If xx and y vary directly and y is 21 when x is 7, find y when x is 5

Answers

Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Answer: y = 15

The formula for volume is length times width times height so it would be 18×18×6 so your answer should be 1,944

Answer:

well i got two answers

Step-by-step explanation:

to find volume the equation is L*W*H and in the problem it says is 6 by 6 by 6 so just multiply them together to get 216 but the model says that is 18*18*6 which equals 1944

Y = 4x + 9
What is the slope and the y-intercept?

Answers

Answer:

y=4x+9 is in the form y=mx+b , so the slope ( m ) is 4 and the Y-intercept ( b ) is 9

Answer:

m = 4b = 9

Step-by-step explanation:

We know that:

y = mx + by = 4x + 9

If we compare these two equations, we can find the slope and the y-intercept.

=> (y = mx + b) = (y = 4x + 9)

We can clearly see that 'm = 4' and 'b = 9'.

Conclusion:

Therefore:

m = 4b = 9

Answers

Answer:

0.35(800)=x

x=number of tickets sold in advance

Step-by-step explanation:

Answer:

Divide 35÷100 which equals 0.35 then multiply 0.35×800 which equals 280 so the answer is 280 so the equation is 0.35×800=280.

What number can be divided into 9 and 10 equal groups without a remainder?
A. 60
B. 80
C. 150
D. 180

Answers

Answer:

D) 180

Step-by-step explanation:

60/10 has no remainder, but 60/9 has a remainder, so it's not A

80/10 has no remainder, but 80/9 has a remainder, so it's not B

150/10 has no remainder, but 150/9 has a remainder, so it's not C

180/10 has no remainder and so does 180/9, so it's D

Answer:

180

Step-by-step explanation:

The question is trying to ask which one can be divided by 9, and 10.

Solution 1:

60/9 = 6.666 ❌

80/9 = 8.888 ❌

150/9 = 16.666 ❌

180/9 = 20 ✔

180/10 = 18 ✔

180

Solution 2:

The LCM of 9 and 10 is 90, so we're trying to find a number divisible by 90. The only number that is divisible by 90 is 180, thus 180 is our answer

A. 1607.7

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

Thus, the first option is correct.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
