A line containing the points (4,1) and (0,0) intersects a line containing (1,0) and (-1,y). If the lines are perpendicular, what is the value of y?
Answers
Answer:
(-1,-8)
Step-by-step explanation:
the first line has a slope of 1-0/4-0 = 1/4
and a perpendicular slope should have different sign and the fraction flipped which means we need to find a slope of -4 for the perpendicular line
0-y/1-(-1)=-4
-y/-2=-4
y=-8

A circle’s circumference is 600 m.
What is a good approximation of the circle’s area? 1. 300\ m^{2} 2. 3,000\ m^{2} 3. 30,000\ m^{2} 4. 300,000\ m^{2}
Answers
The area of the circle is approximately 30,000 [tex]m^{2}[/tex]
The circumference of the circle is given as 600m.
And we know that circumference = [tex]2\pi r[/tex] where r is the radius of the circle.
Therefore,
[tex]2\pi r = 600[/tex]
[tex]r = \frac{600}{2\pi }[/tex]
[tex]r = \frac{300}{\pi }[/tex]
Now, we know that area of the circle = [tex]\pi r^{2}[/tex]
Putting the value of r in this, we get
area = [tex]\pi (\frac{300}{\pi } )^{2}[/tex]
area = [tex]\pi.\frac{300}{\pi } .\frac{300}{\pi }[/tex]
Therefore, area of the circle = 28,647.889 [tex]m^{2}[/tex]
Therefore, the correct answer is 30,000 [tex]m^{2}[/tex]

Which table shows a function that is decreasing only over the interval (–1, ∞)?
What answer is it and why? To me it seems it can either be C or D (One all the way to the right on the top row and one all the way to the bottom right), but I'm not sure why it would be either one over the other and would need an explanation. If it is neither C nor D I need an explanation on how to solve this question correctly.
Answers
Answer: The table to the farthest right the last one.
Explanation:
The interval (-1, ∞) represents x-values anywhere from -1 and higher.
As such, you are looking for a table with y-values that decrease as the x-values increase.
Starting from -1 -
The first option: -5, -2, -1, 2. This is increasing.
The second option: -7, -6, 1, -1. This increases from -7 to -6 to 1.
The third option: -1, 2, 1, -6. This increases from -1 to 2.
The fourth option: 1, 0, -4, -8. This decreases across all coordinates in the range specified.

You have 2 different savings accounts. For Account A, the simple interest earned after 21 months is $5.95. For Account B, the simple interest earned after 30 months is $36.00. If the interest rate is %3.4 for Account A and %2.4 for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Answers
Answer: Principal amount is A = $250.09
Principal amount is B = $400.
Account B earned you the most interest the first month
The formula for simple interest is expressed as
I = PRT/100
Where
P = the principal or initial amount of money invested.
R = interest rate
T = time
On account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years.
Using the formula:
On account B,
I = $13.80
R = 2.3%
T = 18 months = 18/12 = 1.5 years
Using the formula:
To determine the account that earned more interest in the first month we divide the interest by the number of months.
$6.94/9 = $0.7711
$13.80/18 = $0.7667
Account B earned you the most interest the first month because $0.7667 is higher than $0.7711.

Answer: The difference between the angle measure is 152 degrees
Step-by-step explanation: Supplementary angles are angles that add up to 180
So if one angle is x in this case, the other will be 14x
Adding both ;
x + 14x = 180
15x = 180
x = 180/15
x = 12
The other angle is 14 * 12 = 168
The difference between the two will be;
168-12 = 156
Answer:
168
Step-by-step explanation:
m<B + m<C = 180 since the angles are supplementary.
m<B = 14m<C since the measure of angle B is 14 times the measure of angle C.
m<B + m<C = 180
14m<C + m<C = 180
15m<C = 180
m<C = 180/15
m<C = 12
m<B = 14m<C = 14 × 12
m<B = 168
Answer: 168

Given:
A = $5,000P = $4,000r = 5% = 0.05Substitute the given values into the formula and solve for t:
[tex]\implies 5000=4000(1+0.05t)[/tex]
[tex]\implies \dfrac{5000}{4000}=1+0.05t[/tex]
[tex]\implies1.25=1+0.05t[/tex]
[tex]\implies 0.05t=1.25-1[/tex]
[tex]\implies 0.05t=0.25[/tex]
[tex]\implies t=\dfrac{0.25}{0.05}[/tex]
[tex]\implies t=5\; \rm years=60\; months[/tex]
Given:
A = $11,160r = 8% = 0.08t = 36 months = 3 yearsSubstitute the given values into the formula and solve for P:

[tex]\implies 11160=P(1.24)[/tex]
[tex]\implies P=\dfrac{11160}{1.24}[/tex]
[tex]\implies P=\$9000[/tex]
Given:
A = $3,207P = $3,000t = 18 months = 1.5 yearsSubstitute the given values into the formula and solve for r:
[tex]\implies 3207=3000(1+r \cdot 1.5)[/tex]
[tex]\implies \dfrac{3207}{3000}=1+1.5r[/tex]
[tex]\implies 1.069=1+1.5r[/tex]
[tex]\implies 1.5r=1.069-1[/tex]

A bakery sold 36 brownies in a day, which was 30% of the total items sold that day. What was the total number of items the bakery sold that day?
(show work please)
Answers
Answer: The answer is 120
Step-by-step explanation:
We know that 36 is 30% of total items
So our equation would be 36/? = 30/100
From there we cross multiply so 36x100 = 3600
From there, we divide 3600 by 100
Therefore, your answer is 120
A sporting goods store is having a sale in which all sleeping bags are discounted by 20%. Priya has a coupon for $5 off the regular price of a sleeping bag. The store first applies this coupon and then takes 20% off the reduced price. If Priya pays $34.40 for the sleeping bag, what was the original price, x, before the sale and without the coupon?
Answers
the original price was "x", which oddly enough is the 100%.
now, let's pluck out of "x" 5 bucks, so that makes it "x-5", that's our new adjusted 100%, from which the lady at the counter is happy to apply a 20% discount. Now, if the lady discounts 20% off of that "x-5" amount, what Priya is really paying for the sleeping bag is just 100% - 20% = 80%, and we happen to know that that 80% was really $34.40.
now, if "x - 5" is the 100%, and we know that 34.40 is the 80%, what the heck is "x"?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x-5 & 100\\ 34.40& 80 \end{array} \implies \cfrac{x-5}{34.40}~~=~~\cfrac{100}{80} \implies \cfrac{ x-5 }{ 34.40 } ~~=~~ \cfrac{ 5 }{ 4 } \\\\\\ 4x-20=172\implies 4x=192\implies x=\cfrac{192}{4}\implies x=48[/tex]
