Answer:
13.85$
Step-by-step explanation:
105$-8$=97$
97$/7$=13.85$
Answer: About $13.86
Step-by-step explanation: To find how much the cost of the forks is, we need to subtract the value of the lunch box from the total cost, because we don't need to find the value of the lunch box. So:
105 - 8 = 97
So, now since he bought 7 forks, we need to divide 7 by 97. So:
97 / 7 = 13.857142857142858
So, we need to round to the nearest cent. So, the 7 is greater than 5, so we round up. So, we have $13.86 each. So, check, we do:
13.86(7) + 8
97.02 + 8
= 105.02
This is the closest he can buy for each fork is ABOUT $13.86. I hope this helps ;)
pete runs an ice cream stand that also sells snow cones served in paper cones. the paper cones he usually uses have a diameter of 6 inches and a height of 2 inches, but his supplier is out of them. as a replacement, he purchases paper cones with a diameter of 2 inches and a height of 6 inches. how do the volumes of the original and replacement cones compare?
Answer:
replacement is 1/3 the volume of the original
Step-by-step explanation:
You want to compare the volumes of a cone with diameter 6 in and height 2 in to one with a diameter of 2 in and height of 6 in.
VolumeThe volume of a cone is jointly proportional to the height and the square of the diameter:
V ∝ d²h
RatioThe ratio of the volume of the replacement cone to the original is ...
r = V2/V1 = ((2 in)²(6 in))/((6 in²)(2 in) = 2/6 = 1/3
The replacement cone has 1/3 the volume of the original.
According to the United States Census Bureau, the state of Texas had a population of 16,986,510 in 1990. Census data shows that in 2000, the population of Texas was 20,851,820. Find the percent of change.
Answer:
22.7551745473%
Step-by-step explanation:
I could be very wrong but to find the percentage of change you have to divide the increase by the original number, and then multiply it by 100.
20851820-16986510=3865310
3865310/16986510=0.22755174547
0.22755174547*100=22.755174547
This answer can then be rounded up to 23%

Line m passes through points (7, 6) and (5, 13). Line n is perpendicular to m. What is the
slope of line n?
Answer:
-3.5
Step-by-step explanation:
To find the slope of line n, we need to find the slope of line m first. The slope of a line is calculated by dividing the difference in the y-coordinates of two points on the line by the difference in the x-coordinates of the same two points. In this case, we can use the two points (7, 6) and (5, 13) to calculate the slope of line m. The difference in the y-coordinates of these two points is 13 - 6 = 7, and the difference in the x-coordinates is 5 - 7 = -2. Dividing the difference in the y-coordinates by the difference in the x-coordinates yields 7 / -2 = -3.5.
A line is perpendicular to another line if the product of their slopes is -1. Since the slope of line m is -3.5, the slope of line n, which is perpendicular to line m, is -1 / -3.5 = 1/3.5 = <<-1/-3.5=1/3.5>>1/3.5.
Answer:
Slope of a line equation.
Formula for slope of line n is m= rise/run. y2-y1/x2-x1
(7,6) is (x1, y1) and (5,13) is (x2,y2). Simply plug these values in to the equation and solve.
Step-by-step explanation:
(13)-(6) = 7.
(5)-(7) = -2.
7/-2 = - 7/2
- 7/2 = -3.5.
Perpendicular just means that the 1. answer changes sign (pos/neg). This answer is negative, so it becomes a positive. 2. the denominator number switches places with the numerator number. so 7/2 becomes 2/7. Decimal version is 3.5/1 becomes 1/3.5
Final Answer: 1/3.5 or 2/7
find the length of the curve. r(t) = 4t i + 8t3/2 j + 9t2 k, 0 ≤ t ≤ 1
The length of the curve [tex]r(t) = 4t i + 8t^{3/2} j + 9t^{2}k, 0\leq t\leq 1[/tex] is 13.
The given curve is defined by the parametric equation [tex]r(t) = 4t i + 8t^{3/2} j + 9t^{2}k, 0\leq t\leq 1[/tex].
The length of a curve is given by the formula
⇒ [tex]|| r(t) || = \int\limits^a_b {\sqrt{{(x')^{2}} + (y')^{2} + (z')^{2} } } \, dt[/tex]
where the variables x', y', z' are defined as
[tex]x' = \frac{d(4t)}{dt} = 4 \\y' = \frac{d(8t^{3/2})}{dt} = 12t^{1/2} \\x' = \frac{d(9t^{2})}{dt} = 18t\\[/tex]
Hence, substituting the values in the formula for the length
⇒ [tex]|| r(t) || = \int\limits^0_1 {\sqrt{{(4)^{2}} + (12t^{1/2})^{2} + (18t)^{2} } } \, dt[/tex]
⇒ [tex]|| r(t) || = \int\limits^0_1 {\sqrt{{16 + 144t + 324t^{2}} } \, dt[/tex]
The given definite integral is in the form of
[tex]\int\limits^a_b {\sqrt{P(x)}} \, dx = \int\limits^a_b {\sqrt{{ax^{2} + bx + c}} } \, dx[/tex]
where P(x) is a polynomial of degree 2.
Writing the polynomial P(x) as
⇒ [tex]\sqrt{P(x)} = \sqrt{a}\sqrt{{(x + b_1)^{2} + c_1}} dx[/tex]
⇒ [tex]\int\limits^a_b {\sqrt{P(x)}} \, dx = \sqrt{a}\int\limits^a_b {\sqrt{{(x + b_1)^{2} + c_1}}} \, dx[/tex]
where [tex]b_1, c_1[/tex] are defined as
⇒ [tex]b_1= \frac{a}{2b} \\c1 = \frac{c}{a} - b_1^{2}[/tex]
Therefore, the solution will be
⇒ [tex]\int\limits^a_b {\sqrt{{(x + b_1)^{2} + c_1}}} \, dx = \frac{(b_1 + x)\sqrt{P(x)} + c_1log{(b_1 + x + \sqrt{P(x)}}}{2}[/tex]
Hence, solving the integral
⇒ [tex]|| r(t) || = \int\limits^0_1 {\sqrt{{16 + 144t + 324t^{2}} } \, dt[/tex]

According to the IRS, taxpayers calling the IRS in 2017 waited 13 minutes on average for an IRS telephone assister to answer. Do callers who use the IRS help line early in the day have a shorter wait? Suppose a sample of 50 callers who placed their calls to the IRS in the first 30 minutes that the line is open during the day have a mean waiting time of 11 minutes before an IRS telephone assister answers. Based on data from past years, you can assume that the standard deviation of waiting times is 8 minutes. Using these sample results, can you conclude that the waiting time for calls placed during the first 30 minutes the IRS help line is open each day is significantly less that the overall mean waiting time of 13 minutes? Use alpha=0.05
- Establish the two hypotheses
- Calculate the test statistic
- Make a decision using the critical value approach
- Make a decision using the p-value approach
We can reject the null hypothesis and conclude that the mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is significantly less than the overall mean waiting time of 13 minutes.
Two-Hypotheses:
H0: The mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is not significantly less than the overall mean waiting time of 13 minutes.
Ha: The mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is significantly less than the overall mean waiting time of 13 minutes.
Test Statistic: t = (11 - 13) / (8/√50) = -2.5 and the Critical Value Approach is: The critical value for a one-tailed test at alpha = 0.05 is 1.645. Since the test statistic (-2.5) is less than the critical value (1.645), we can reject the null hypothesis and conclude that the mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is significantly less than the overall mean waiting time of 13 minutes, and the P-Value Approach: The p-value for the one-tailed test is 0.0062. Since this p-value is less than alpha = 0.05, we can reject the null hypothesis and conclude that the mean waiting time for calls placed during the first 30 minutes the IRS helpline is open each day is significantly less than the overall mean waiting time of 13 minutes.

5. Sima invests some money in an account that earns a fixed rate of interest
compounded annually. The amounts of the investment at the end of the first
three years are shown below
a) Determine the annual rate of compound interest earned.
b) How much did Sima invest?
Year. Total amount
1. $4240.00
2. $4494.40
3 $4764.06
Answer:
Step-by-step explanation: To solve this problem, we can use the following formula for compound interest:
A = P * (1 + r/n)^(n*t)
Where:
A is the total amount at the end of the period
P is the principal (initial investment)
r is the annual interest rate
n is the number of times the interest is compounded per year
t is the number of years
We can rearrange this formula to solve for r:
r = n * ((A/P)^(1/n*t) - 1)
We can plug in the values for A, P, and t for each year to solve for the annual interest rate:
Year 1:
r = n * ((4240.00/P)^(1/n*1) - 1)
r = 1 * ((4240.00/P)^(1/1) - 1)
r = (4240.00/P) - 1
r = 4240.00/P - 1
r = 4240.00 - P/P
r = 4240.00 - 1
r = 0.08
Year 2:
r = n * ((4494.40/P)^(1/n*2) - 1)
r = 1 * ((4494.40/P)^(1/2) - 1)
r = (4494.40/P)^(1/2) - 1
r = 4494.40/P - 1
r = 4494.40 - P/P
r = 4494.40 - 1
r = 0.08
Year 3:
r = n * ((4764.06/P)^(1/n*3) - 1)
r = 1 * ((4764.06/P)^(1/3) - 1)
r = (4764.06/P)^(1/3) - 1
r = 4764.06/P - 1
r = 4764.06 - P/P
r = 4764.06 - 1
r = 0.08
Since the annual interest rate is consistent at 0.08 for all three years, we can conclude that this is the annual rate of compound interest earned.
To solve for the principal, we can use the formula for compound interest again, this time solving for P:
P = A / (1 + r/n)^(n*t)
Plugging in the values for A, r, and t for each year, we get:
Year 1:
P = 4240.00 / (1 + 0.08/1)^(1*1)
P = 4240.00 / 1.08
P = 3925.93
Year 2:
P = 4494.40 / (1 + 0.08/1)^(1*2)
P = 4494.40 / 1.16
P = 3925.93
Year 3:
P = 4764.06 / (1 + 0.08/1)^(1*3)
P = 4764.06 / 1.24
P = 3925.93
Since the principal is consistent at $3925.93 for all three years, we can conclude that this is the amount Sima invested.

Step-by-step explanation:
the angle south-east of x is hard to read.
I assume this is 86 (but could be also 96).
remember, the sum of all angles in a triangle is always 180°.
and the intersection angles between 2 lines are the same in both sides of the lines. the only difference between above and below angles is that they are left-right mirrored.
so,
180 = x + 22 + 86
x = 180 - 22 - 86 = 72°
x and y are intersection angles of 2 lines and are therefore equal (due to the left-right mirroring).
y = x = 72°
180 = w + 33 + 72
w = 180 - 33 - 72 = 75°
remember also that the sum of all angles around a single point on one side of a line is always 180°, because the line can be seen as diameter of a circle with the point being the circle center. and the degrees of a half-circle are 180°.
180 = angle1 + unnamed angle = angle1 + 85
angle1 = 180 - 85 = 95°
180 = angle2 + angle3 + unnamed angle =
= 42 + angle3 + 85
angle3 = 180 - 42 - 85 = 53°
for the third question we don't see a picture of the situation. I assume this is a circle with O being the center of the circle, and Q, N, P are points on the circle arc.
it is not clear, if the angle QOP is part of the angle QON, or if they are separate segments of the circle.
if the angle QOP is part of the angle QON, then the angle PON = 142 - 46 = 96°
if the angle QOP is separate from the angle QON, then the angle PON = 360 - 142 - 46 = 172°

a van full of storm chasers is driving along a straight road at 94 kilometers per hour in hopes of filming a tornado. the tornado, 7 kilometers away, is traveling along the same road and moving directly toward them, traveling at 69 kilometers per hour. if neither the van nor the tornado changes course, how long will it be before they meet?
The time taken to traveled the van and the tornado before they meet as per the speed of the van and the tornado is equal to 2.6 minutes.
As given in the question,
Speed of the van along the straight road = 94 kilometers per hour
After travelling distance of 7 kilometers
Speed of the tornado along the same road = 69 km/hour
Total relative speed of van and tornado = 94 + 69
= 163km/hour
Distance travelled between two different speed = 7km
Time used to traveled before they meet = distance / speed
= 7 / 163
= 0.043 hours
= 2.58minutes
= 2.6minutes
Therefore, the time required to traveled the van and the tornado before they meet is equal to 2.6 minutes.

This problem can be solved using divide and conquer techniques. An method known as "divide and conquer" works by breaking down a large task into smaller ones.
An algorithmic pattern is known as Divide and Conquer. In algorithmic approaches, the idea is to take a dispute involving a large amount of input, divide the input into smaller pieces, solve the problem on each of the smaller pieces, and then combine the piecewise solutions into a comprehensive solution. The Divide and Conquer is the algorithmic name of the approach that was used to solve the issue.
The three steps below are used in a dispute utilizing the Divide and Conquer method.
Create a group of subproblems from the main issue.
Conquer: Recursively and individually solve each subproblem.
Combine: Combine the solutions to the individual subproblems to arrive at the overall solution.

what is the probablity that six consecutive integers will be chosen as the winning lottery numbers where each number chsoen is an integer between 1 and 40
The probability is 0.00000911843.
The number of terms is 40 because the number selected falls within the range of integers 1 through 40 (inclusive).
Thus; n = 40
The combination formula, which is; gives the probability that 6 integers (r = 6)—the number of possible outcomes—will be obtained without repetition.
C(n, r) = n!/((n - r)!(n - r)!)
C(40, 6) = 40!/(6!(40 - 6)!)
C(40,6) = 3838380

An object is moving at a speed of 6 inches every 4 to 5 days. express the speed in yards per year. round your answer to the nearest 10th
Answer:
The speed in yards per year is 60.8.
Step-by-step explanation:
To convert the speed from inches per day to yards per year, we need to first convert the speed to inches per year and then convert the units to yards per year.
First, we can convert the speed to inches per year by multiplying the speed by the number of days in a year:
Speed (inches/day) * Days per year = Speed (inches/year)
6 inches/day * 365 days/year = 2190 inches/year
Next, we can convert the units to yards per year by dividing the speed in inches per year by the number of inches per yard:
Speed (inches/year) / Inches per yard = Speed (yards/year)
2190 inches/year / 36 inches/yard = 60.8 yards/year
Rounding to the nearest 10th, we have:
60.8 yards/year ≈ 60.8 yards/year
Therefore, the speed in yards per year is 60.8.
An isosceles triangle has a base that is 3 times the length of its legs. The perimeter of the triangle is 45 cm. What is the length of the base?
Answer:
27cm
Step-by-step explanation:
[tex]s + s + s = p \\3x + x + x = 45 \\ 5x = 45 \\ \frac{5x}{5} = \frac{45}{5} \\ x = 9[/tex]
That's the length of one of its legs
The length of the base = 3x
= 3 x 9

Inez heard that a a general rule, he hould pend no more than 30% of her take-home pay on rent. If Inez' take-home pay i $46. 800 per year, what i the maximum amount per month that he hould pent or rent?
The maximum amount per month that Inez would spent on rent is $1170 knowing that he could spend no more than 30% of the take home pay.
Here Inez heard that a a general rule, he should pend no more than 30% of her take-home pay on rent. If Inez' take-home pay i $46. 800 per year.
The term Take-home pay is the net amount of income received after the deduction of taxes, benefits, and voluntary contributions from a paycheck. It is the difference resulting from the subtraction of all deductions from gross income.
Pay = $46,800
Total allowed = 46,800 x 0.30
Total allowed = $14,040
Now since we know that there are 12 months in a year, we need to divide the Total allowed by 12 to find how much Inez can pay in rent per month.
14,040 / 12 = $1,170
Following the rule that he could not spend more than certain of the take home pay he should rent $1170.
