· 2πr Use the formula for arc length.
=
90
360
· 2π(3) Substitute 3 for r and 90 for m.
= 1.5π Simplify.
Let t be the length of the cut encompassing the tray.
t = 2 · 1.5π + 2 · 6
= 3π + 12 Simplify.
≈ 21.5 ft Use a calculator to evaluate. Then round your answer to the nearest half foot.

18. A jar contains 200 coins.
• Zack pulls out a coin, records its value, and then puts the coin back into the jar.
• Zack does this same process 8 times and records 1 quarter, 2 dimes, 2 nickels, and
3 pennies.
Based on these results, how many coins in the jar can Zach expect to have a value of
$0.10 or more?
А
75
B.
67
C. 50
D. 25
Answers
Answer:
Step-by-step explanation:
3 coins pulled are 10 cents or more
5 coins are under 10 cents
so 3 out of 8 coins are 10 cents or more
the jar contains 200 coins
This is a ratio problem 3 is to 8 as x (an unknown value) is to 200
3/8 = x/200 solve for x
times both sides by 200
200(3/8) = x solve directly here using a calculator
600/8 = x or keep similifying until you can divide more
300/4 = x easily I kept dividing the numerator and the
150/2 = x denominator by 2 until i got 150/2 = 75
75 = x

What is the measure of angle D?
Answers
Answer:
m<D = 26
Step-by-step explanation:
<D = x
x + 122 + 32 = 180
x + 154 = 180
x = 180 - 154
x = 26
Answer:
Step-by-step explanation:
<D + 122° + 32° = 180° ( being sum of angles of triangle )
< D = 180° - 154°
< D = 26°

What is the height of a tree if a man standing 5 feet tall is 42 ft from the tree and sees the top of the tree at an angle of elevation of 32°?
Answers
Answer: [tex]31.24\ ft[/tex]
Step-by-step explanation:
Given
The height of a man is 5 ft
Distance between man and tree is 42 ft
the angle of elevation is [tex]32^{\circ}[/tex]
Suppose h is the height of the tree
[tex]\Rightarrow \tan 32^{\circ}=\dfrac{h-5}{42}\\\\\Rightarrow h-5=26.24\\\Rightarrow h=31.24\ ft[/tex]

Which of the following expressions are equivalent to -4/7 - 8/9 + 4/7 + 9/8?
Answers
Answer:
C and D
Step-by-step explanation:
I'm too braindead to explain this, read comments
Answer:
-2 1/72
Step-by-step explanation:
Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.

Samantha bought a refrigerator that is 3 1/2 feet wide, 5 1/2 feet tall, and 2 1/2 feet deep. How much space will the new refrigerator occupy?
Answers
Answer:
48.125 ft³
Step-by-step explanation:
The space occupied by the new generator is the product of it's dimension:
The space occupied = Length * width * height
Space occupied = 3 1/2 * 5 1/2 * 2 1/2
Space occupied = 7/2 * 11/2 * 5/2
Space occupied = (7*11*5) / (2*2*2) = 385 / 8
Space occupied = 48.125 ft³

You deposit 500 in a savings account that earns 9% annual interest compounded monthly. Enter a function that represents the balance y (in dollars) after t years
Answers
Answer: y = 500 * ( 1 + 0.75%) ^ (t * 12)
Step-by-step explanation:
Formula for calculating the amount of money in an account as a result of compound interest is:
Balance = Amount * ( 1 + rate) ^ no. of periods
This interest is compounded monthly so has to be converted to a monthly rate:
= 9% / 12
= 0.75%
t is in years so has to be converted as well to months:
= t * 12 months
Function is therefore:
y = 500 * ( 1 + 0.75%) ^ (t * 12)
