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
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
Ms. Etienne deposited $450 into an account that paid 5% interest compounded annually. She did not make any
additional deposits or withdrawals.
Which amount is closest to the value of the account at the end of 6 years?
A $603.04
B $585.00
© $463.67
o
$463.50
Answer:
$603.04
Step-by-step explanation:
The Compound Amout formula is A = P(1 + r)^t, where:
P is the principal (initial deposit), r is the annual interest rate as a decimal fraction, and t is the time period in years.
In this particular case, the Compound Amount is:
A = ($450)(1 + 0. 05)^6 = ($450)(1.34) = $603.04

Write each fraction in simplest form. If it is in
simplest form, write simplest forms. 7. 4/12
Answer:
1/3
Step-by-step explanation:
To put it in simplest form, swap the numbers and evaluate:
4/12 = 12/4
12 divided by 4 is equal to 3
4 multiplied by 3 is equal to 12
Therefore, the correct answer is 1/3
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°?
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]
It 16x = (141)²-(109)², then
the value of x is.
(a). 150
(b). 500
(c). 600
(d). 32
Answer:
b) 500
16x = (141)^2 - (109)^2
or, 16x = 19881 - 11881
or, x = 8000/16=500
Based on the diagram, which expresses all possible
lengths of segment AB?
A. AB = 25
B. 27 < AB <81
C. AB = 85
D. AB < 27 or AB > 81
Answer:
B
Step-by-step explanation:
Given 2 sides of a triangle then the third side is in the range
difference of 2 sides < AB < sum of 2 sides , that is
54 - 27 < AB < 54 + 27
27 < AB < 81 → B

Use triangles to find the sum of the interior angle measures of the polygon.
Answer:
1440°
Step-by-step explanation:
From the 8 sided diagram, 8 triangles can be obtained. 1 triangle adds up to 180° thus for the diagram ,sum of interior will be 180°×8=1440°
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
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)

h/6-1=-3 Please help me with this math problem.
Answer:
[tex]h=-15[/tex]
Step-by-step explanation:
[tex]\frac{h}{6-1}=-3[/tex]
Simplify:
[tex]\frac{1}{5} h=-3[/tex]
Multiply both sides by 5:
[tex]5\times(\frac{1}{5}h)=(5)\times(-3)\\h=-15[/tex]
h = -15 is your final answer.
Answer:
h = -15Step-by-step explanation:
[tex] \frac{h}{6 - 1} = - 3 \\ \: \: \: \: \: \: \frac{h}{5} = - 3 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: h = 5 \times ( - 3) \\ \: \: \: \: \: \: \: \: \: h = - 15[/tex]

What is the measure of angle D?
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°
