Use the value 3.14 for it, and do not round your answer.
Answer:
A = 78.5 ft^2
Step-by-step explanation:
A = 3.14 x 5^2
= 3.14 x 25
The area is:
78.5 ft²Explanation:
To find the circle's area, use the formula [tex]\sf{A=\pi r^2}[/tex].

[tex]Sin QPS=\frac{Opposite}{hypotenuse}[/tex]
sin 15° = [tex]\frac{QS}{PQ}[/tex]
QS= sin 15° * PQ
QS = 0.2588 * 12.6 = 3.36088 ≈ 3.4m
a. The length of QS = 3.4m
b. [tex]cos QPS=\frac{Adjacent}{Hypotenuse}[/tex]
Cos 15° = [tex]\frac{PS}{PQ}[/tex]
PS = Cos 15° * PQ
PS = O.9659 * 12.6 = 12. 17034 ≈ 12.2m
The length of PS = 12.2m
The owner of a small store buys coats for $40.00 each .she sells the coats for $7200 each. What percent of the purchase price is the sale price? The owner increased the price by the same percent
Answer:
Step-by-step explanation:
0056 because 1% is 72 so you know it’s going to have to be less then 72. So to get your percent you divide 40 by 7200 so 40/7200. This will get you .00555556 which I rounded to .0056

Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and (–12, –9). He writes the equation
7x – 10y = 3. Is this a good model? Explain your reasoning.
Answer:
No. Correct is 7x - 10y = 6.
Step-by-step explanation:
The slope of the line is (-9-5)/(-12-8) = 7/10
y - 5 = 7/10(x - 8)
10y - 50 = 7(x - 8)
10y - 50 = 7x - 56
7x - 10y = -50 + 56
7x - 10y = 6.
Explanation:
Let's plug in x = 8 and y = 5. This is directly from the ordered pair (8,5).
7x - 10y = 3
7*8 - 10*5 = 3
56 - 50 = 3
6 = 3
We get a false equation at the end, which means the original equation is false when (x,y) = (8,5). Therefore, the point (8,5) is not on the line 7x-10y = 3. Furthermore it means that 7x-10y = 3 is not a good model since Devon wanted the line to pass through both given points.
If you were to plug in (x,y) = (-12,-9), then you would find the same thing happens. For each ordered pair, the left side results in 6. So if Devon were to change that "3" to "6", then it would be a good model as both points would be on the line. In other words, the standard form equation Devon should use is 7x-10y = 6. When solving for y, Devon would get y = (-7/10)x - 3/5
Below is visual confirmation that 7x-10y = 3 is not a good model. Both points are not on the line. The graph was made using GeoGebra.
The charges for an international call made using the calling card for two phone companies are shown in the table. a. What is the length of a phone call that would cost the same no matter which company is used? b. Analyze Relationships When is it better to use the card from Company B?
Phone Company Charges
Company A 35¢ plus 3¢ per minute
Company B 45¢ plus 2¢ per minute
Answer: 10 minutes
Step-by-step explanation:
Let x be minutes.
Toatl costs for a call are:
A: 35 + 3x
B: 45 + 2x
When will A = B?
35 + 3x = 45 + 2x
1x = 10
They are equal cost at 10 minutes

The sales tax rate in New Mexico is 5.125%. Select all the equations that represent the sales tax, t, you would pay in New Mexico for an item of cost c?
Group of answer choices
Answer:
c = c + (c × t %) or c = c + (c × .05125)
Step-by-step explanation:
c = cost
t = sale tax % 5.125% = .05125 as a decimal.
c = c + ( c × t %) or c = c + (c × .05125 )

1)Solve 3x+2= 5
A. Model 3 2 x+ = 5.
B. Perform the step to have the variables (circles) alone on one side.
C. Write the resulting step.
D. Divide the variables (circles) and numbers (squares) into equal groups.
E. Show the value of one group.
The value of x in the equation, 3x + 2 = 5 is 1.
In order to solve this equation: 3x + 2 = 5, take the following steps:
Combine similar terms together:
3x = 5 - 2
Add the similar terms together
3x = 3
Divide both sides of the equation by 3 in order to make x the subject f the formula
3x / 3 = 3 /3
x = 1

Find the exact circumference.
Answer:
25π
Step-by-step explanation:
C= πd
d=√(24²+7²)=√(576+49)=√625=25
C=25π
Answer:
Step-by-step explanation:
First off, divide 24 by 2 as that would give you the radius of the circle
24cm / 2cm = 12cm
Next, use the formula to calculate the circumference of a circle and plug in radius:
C = 2 x π x r
= 2 x π x 12cm
= 75.40cm is the circumference

55.99 dollars gift with 18% coupon and 7.25% sales tax. What is the final cost?
Answer:
I think it is $91.89.
Step-by-step explanation:
1. Take the number and add sales tax by multiplying 0.0725 ( since that is what the percentage is in a decimal form). Then add that to the original and you have what it would be plus sales tax: $60.05.
2. Then you would need to multiply by 0.18. You would get 10.809
3. Next, subtract the 10.809 from $60.05 and the answer is $49.24.

The cost of admission to a festival was $112 for 9 children and 3 adults. The admission was $108 for 8 children and 3 adults in another festival. How much was the admission for each child and adult?
Answer:
cost of admission for each child was $4.00, and each adult was $25.33
Step-by-step explanation:
When solving questions like these , I like to break down the problem so I understand it better.
Let x ---> cost of the admission for each child
Y ---------> cost of the admission for each adult
9x+3y = 112 ---> equation A
8x + 3y = 108 ---> equation B
Subtract B from A
9x+3y=112
-8x+3y = 108
x = 112-108
x = 4
Find value of y by substituting value of x into equation
9(4)+3y=112
Solve for y
36+3y = 112
3y = 112=36
3y = 76
y = 25.33
An inch is exactly 2.54 centimeters. Write an equation to convert the number of inches x to the corresponding length in centimeters.
Answer:
What's 2.54 cm in inches?
To convert cm to inches, divide your cm figure by 2.54 or multiply it by 0.3937. As an example, let's say you have a piece of wood measuring 50cm and you want to convert it into inches. To get your answer, divide your cm figure by 2.54. So, 50 ÷ 2.54 = 19.685 inches.
Step-by-step explanation:
Answer: 2.54x12 is 30.48
We can write:
2.54x
Where 'x' is the number of inches.
Plug in 12 for 'x':
2.54(12)
30.48
So 12 inches is approximately 30.48 centimeters.

In the Diagram below DE≅AE ,BA∥CE
, CB∥DA
and m∠C=65∘
Find m∠BAE
Answer:
∠ DAE = 130°
Step-by-step explanation:
ABCD is a parallelogram ( opposite sides are parallel )
The opposite angles of a parallelogram are congruent , then
∠ BAD = ∠ BCD = 65°
∠ ADE = ∠ BAD = 65° ( alternate angles )
Since DE = AE then Δ ADE is isosceles with 2 base angles congruent, that is
∠ DAE = ∠ ADE = 65°
Then
∠ BAE = ∠ BAD + ∠ DAE = 65° + 65° = 130°
