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.

The probability of drawing 3 aces and 2 kings is 9.23×[tex]10^{-6}[/tex] and the probability of a “full house” is 0.00144.

5 cards are drawn from a standard deck of 52 cards.

a) Probability that we draw 3 aces and 2 kings

Number of cards = 52

No of aces = 4

No of kings = 4

Number of cards drawn = 5

So, the probability becomes,

The possibility is the department of arithmetic concerning numerical descriptions of ways in all likelihood an event is to arise, or how in all likelihood it's miles that a proposition is authentic. The opportunity of an occasion varies between zero and 1, wherein, more, or less speaks to me, 0 suggests the impossibility of the event and 1 shows reality. The better the probability of an event, the much more likely it's far that the event will arise.

An easy example is the tossing of a fair (unbiased) coin. for the reason that coin is fair, the 2 effects ("heads" and "tails") are each equally probable; the opportunity of "heads" equals the possibility of "tails"; and considering no other outcomes are viable, the opportunity of either "heads" or "tails" is half off (which can additionally be written as 0.5 or 50%).

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.

The volume of a cone is jointly proportional to the height and the square of the diameter:

  V ∝ d²h

The 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.

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°

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

Step-by-step explanation:

For the absolute value function g(x) = |x + 2| + 1, h must be negative and k must be positive.

We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.

In piecewise terms  | x | = x for x ≥ 0 and | x | = - x for x < 0.

We know the coordination of the vertex of an absolute value function

g(x) = |x - h| + k is, (h, k).

Given, An absolute value function has vertex coordinate (- 2, 1).

Therfore the absolue value function g(x) = |x - (-2)| + 1.

g(x) = |x + 2| + 1, The graph is shifted horizontally left by 2 units and up vertically by 1 unit so h must be negative and k must be positive.

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:

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.

Since the stages are simply whole values taken one after the other, they should be whole numbers or integers.

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.
