Then we add the fractions that dont have x.
We only add the numerators (2 and 3) and dont change the denominators (4)
2/4 + 3/4 = 5/4
Now we add the ones with x.
5/4 + 3/4x + 3/4x = 11/4x

Stephen has $500 in an account for 9 months at a compound interest rate of 7.5%. At the end of 9 months, how much money is in his account?
Answers
Answer:
8.12
Step-by-step explanation:
Stephen has approximately $532.72 in his account at the end of 9 months with a 7.5% compound interest rate.
We can use the formula for compound interest to find the amount of money in Stephen's account at the end of 9 months:
A =P \((1 + r/n)^_(nt)\)
where:
A is the amount of money in the account at the end of the period
P is the principal (initial amount) in the account
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the time (in years)
We know that P = $500, r = 0.075 (since the interest rate is 7.5%), n = 12 (since the interest is compounded monthly), and t = 9/12 (since 9 months is three-quarters of a year). Substituting these values into the formula, we get:
A = \($500(1 + 0.075/12)^_{(12*(9/12))\) = \($532.72\)
Therefore, Stephen has approximately $532.72 in his account at the end of 9 months.

A scuba diver is 15.5 feet below the surface of the water. If the diver continues to swim downward at a rate of 2.5 feet per second, what is her location, in feet, relative to the surface after 712 seconds? feet
Answers
The answers is: 33
33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
Step-by-step explanation:
Given:
A scuba diver is 15.5 feet below the surface of the water.
The diver continues to swim downward at a rate of 2.5 feet per second.
Now, to find the integer represents her location relative to the surface after 7 seconds.
And to find how far does the diver have to go to return to the surface.
So, to get the integer represents her location relative to the surface after 7 seconds.
Initial depth = 15.5 feet.
Distance traveled down = 7 × 2.5 = 17.5 feet.
Final depth of water surface = Initial depth + Distance traveled down.
Final depth of water surface = 15.5 feet + 17.5 feet.
Final depth of water surface = 33 feet.
Thus, 33 is the integer represents her location relative to the surface after 7 seconds.
Now, to get how far does the diver have to go to return to the surface:
As, the diver goes to 33 feet down to the surface.
Thus, the diver to return she have to go through the same distance.
So, to return to the surface she need to go to 33 feet far.
Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²

A cylindrical can of vegetables has a label wrapped around the outside, touching end to end. The only parts of the can not covered by the label are the circular top and bottom of the can. If the area of the label is 88π square inches and the radius of the can is 2 inches, what is the height of the can?
22 inches
11 inches
8 inches
4 inches
Answers
Answer:
22 inches
Step-by-step explanation:
The area of the label is the lateral area of the cylinder, which is given by the formula:
A = 2πrh
where r is the radius and h is the height of the cylinder.
We are given that the area of the label is 88π square inches and the radius is 2 inches. Substituting these values into the formula, we get:
88π = 2π(2)(h)
Simplifying, we get:
88 = 4h
Dividing both sides by 4, we get:
h = 22
Therefore, the height of the can is 22 inches. Answer: 22 inches.

A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 18 centimeters. The blueprint has a scale of three centimeters to four feet. What will be the actual ares of the base of the fountain, in square feet, after it is built? Round your answer to the nearest tenth of a square foot.
Answers
Answer:
452.4 square feet
Finding the diameter:
Since there are 3 centimeters for every 4 feet, we need to divide 18 by 3
18 ÷ 3 = 6 which means the ratio is scaled up by 6 so we multiply 4 by 6
4 · 6 = 24 that means that the diameter of the base of the fountain is 24 feet
Finding the area:
Since the area of a circle is πr² we need to divide the diameter by 2 to get the radius(r)
24 ÷ 2 = 12 now we need to square 12 (which is multiplying it to itself ex. 5² is 5 · 5)
12 · 12 = 144 now we multiply it by π
π · 144 ≈ 452.38934 lastly we round it
452.4 square feet

ANSWER BOTH QUESTIONS QUESTION A AND QUESTION B.
Answers
Answer: A) $333
B) $468
Step-by-step explanation:
A) First we multiply. 130x5=650 Now we know that we have to get $650 total in 5 weeks in order to get an average of $130 per week.
87+105+125=317
650-317=333
Necolai has to earn $333 the fifth week to achieve an average of $130 per week.
B) 28% of 650 = 182
Now subtract the taxes from his earnings. 650-182=468
Necolai has $468 of his total pay after taxes.
To find how much Necolai has to earn in the fifth week to achieve an average of $130 per week, we have to use the concept of mean.
The average of five weeks' earnings should be $130. Therefore, the sum of his five-week earnings should be:
5 * 130 = 650
Necolai's total earnings for the first four weeks are:
87 + 105 + 125 + x (earning in the fifth week) = 317 + x
317 + x + y = 650
where y represents his earnings in the fifth week. Solving for y, we get:
y = 650 - 317 - x
y = 333 - x
So, Necolai has to earn $333 in the fifth week to achieve an average of $130 per week.
Question B:
After earning $87, $105, $125, and x dollars (from the third week), Necolai’s total earning are $317 + x. After 5 weeks, Necolai has to pay 28% in taxes, which means he gets to keep 72% of his earnings.
The taxes are calculated as:
Taxes = 0.28 * (317 + x)
Taxes = 88.76 + 0.28x
Therefore, the taxes he has to pay after five weeks are $88.76 + 0.28x.
The portion of his total earnings that he keeps after taxes is:
Total earnings - Taxes = (317 + x) - (88.76 + 0.28x)
Total earnings - Taxes = 228.24 + 0.72x
Therefore, after paying taxes, Necolai is left with $228.24 + 0.72x of his total earnings.

How many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel? Which of the following equations could be used to solve this?
Answers
Answer:
3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.
Step-by-step explanation:
To determine how many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel, the following calculations must be performed:
50 + 0.62X = 78
0.62X = 78 - 50
0.62X = 28
X = 28 / 0.62
X = 45.16
100 - 45.16 = 54.84
54.84 = 4
45.16 = X
45.16 x 4 / 54.84 = X
180.64 / 54.84 = X
3.29 = X
Therefore, 3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.
