Answers
[tex]\\ \sf\longmapsto V=\pi r^2\dfrac{h}{3}[/tex]
[tex]\\ \sf\longmapsto \dfrac{h}{3}=\dfrac{V}{\pi r^2}[/tex]
[tex]\\ \sf\longmapsto h=\dfrac{3V}{\pi r^2}[/tex]
Option B
Answer:
[tex] \hookrightarrow \: { \rm{V = \pi {r}^{2} \frac{h}{3} }} \\ [/tex]

The sidelengths
are x,x+2 and
x+4, what is the
length of the longest
side ?
Answers
Answer:
The longest side is 16 cm
Step-by-step explanation:
[tex]x + (x + 2) + (x + 4) = 42cm \\ x + x + 2 + x + 4 = 42cm \\ 3x + 6 = 42cm \\ 3x = 36cm \\ x = 12[/tex]
check and finish
[tex]12 + (12 + 2) + (12 + 4) = 42cm \\ 12 + 12 + 12 + 6 = 42 cm\\ 36 + 6 = 42cm \\ 42cm = 42cm[/tex]
lengths of sides
[tex]12 + 4 = 16cm \\ 12 + 2 = 14cm \\ 12cm[/tex]

Luisa took a job in which her salary can be modeled by the exponential function y = 36,000(1.025)^x, where x is the number of years after she is hired. Damon took a job with a starting salary of $38,500 and yearly raises of $800. Pick EACH correct statement about the scenario.
[] The difference in the starting salaries is $1,600.
[] The difference in the starting salaries is $2,500.
[] The difference in the starting salaries is $2,000.
[] Luisa will make more money in the first 8 years.
[] Damon will make more money in the first 8 years.
[] They will make the same amount of money in the first 8 years.
Answers
Answer:
B and D are the correct answer
Step-by-step explanation:
I took the test
The difference in the starting salaries is $2,500 and Luisa will make more money in the first 8 years thus (B) and (D) are correct.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
Given salary of Luisa by function,
y = 36,000(1.025)^x
The starting salary of Luisa,
x = 0 → y = 36000(1.025)^0 = $36000
Starting salary Damon = $38500
Difference = 38500 - 36000 = $2500
Amount of money that Luisa make in first 8 years ⇒
36,000(1.025)¹ + 36,000(1.025)² + ...up to 8 times
Amount of money that Damon makes in first 8 years ⇒
38500 + (38500 + 800) + (38500 + 2 × 800) + ...up to 8 times.
The rate of increment of Luisa > Damon
Hence "The difference in the starting salaries is $2,500 and Luisa will make more money in the first 8 years".

The idea behind correct deciphering of word problems is correct understanding of the words used in the question. Both literally and mathematically. “More than” implies that something is greater than something in a literal sense. In mathematics, “a” is “more than” “b”, would be written as a>ba>b. Here even the verb, “is” plays an important role in the formation of the mathematical expression. For example, “a is more than b” means a>ba>b and “a more than b” means a+ba+b.

An equation is 92 + 2x = 180.
The congruent angles each measure 44°.
Step-by-step explanation:
1. If two angles in a triangle are congruent and unknown, we can represent that as 2x. That means 92 + 2x = 180.
2. To find the measure of each congruent angle, x, we have to solve the equation above.
Step 1: Simplify both sides of the equation.
[tex]2x + 92 = 180[/tex]Step 2: Subtract 92 from both sides.
[tex]2x + 92 - 92 = 180 - 92[/tex] [tex]2x = 88[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{88}{2}[/tex] [tex]x = 44[/tex]x = 44 means that the congruent angles each measure 44°.
Answer: 92+2x=180
Step-by-step explanation:
180-92=88
88/2 = 44
x=44

Suppose y varies directly with x, and y= 24 when x= 8. What is the value of y when x=10?
A. 10
B. 30
C. 80
D. 240
Answers
Answer:
[tex]\huge\boxed{\sf y = 30}[/tex]
Step-by-step explanation:
Given that:
y ∝ x
Turning proportionality into equality by putting the constant 'k'
y = kx ---------------------(1)
We know that y = 24, when x = 8
24 = k(8)
Divide both sides by 8
24 / 8 = k
3 = k
OR
k = 3
Now, Finding y when x = 10
Put x = 10 and k = 3 in Eq. (1)
y = (3)(10)
y = 30
