A rectangular prism has a base with an area of 13 square units and a volume of
109.2 cubic units. The equation shown gives the height, h, in units, of the prism.
13h = 109.2
What is the height, in units, of the prism?
​

Answers

Answer:

Isolate the variable and simplify.

Step-by-step explanation:

13h = 109.2

h = 109.2 ÷ 13

h = 8.4

Your answer would be 8.4 units.

There were 220 people who voted at the 6th grade meeting. Sixty percent of the voters are in favor of changing the school mascot. How many people are against changing the mascot? Use numbers and words to explain your answer.

Answers

Step-by-step explanation:

First I had to find 60% of 220.

220 × .60 = 132.

132 people are in favor so I have to subtract that number from 220 to find how many people were against.

220-132 = 88

88 people were against changing the mascot.

The sum of two numbers is 46 and their
difference is 20. What is the smaller
number?
1
A) 40
B) 13
C) 26
D) 12

Answers

46/2 is 23
20/2 is 10
The number is + or - 23
So 13 and 33
13

Answer:

B. 13

Step-by-step explanation:

We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.

"The sum of two numbers is 46 and their difference is 20."

Meaning we have two equations :

X + Y = 46

X - Y = 20

Looking at the last part of "their difference is 20." We can assume X = Y + 20

So substitute the assumed equation into X + Y = 46

(Y + 20) + Y = 46

2y + 20 = 46

Subtract 20 from both sides :

2y = 26

Divide 2 by both sides :

y = 13

There you go.

The graph below shows the solution to which system of inequalities

Answers

Answer:

C. y </ 3/4x +10 and y<l -1/2x - 3

Step-by-step explanation:

Basically first do process of elimination with your focus on one equation

for example :: ( >l is greater then or equal to and <l is lease then or equal to)

focus -> y >l 3/4x + 10

1) determine which line has the y-intercept of positive 10

2) is the line dotted or straight? dotted line = > or < while straight line = >l or <l

this should get rid of B and D now

3) remember this = if the slope is - then the shaded portion would be the way that the less then sign is pointing

( y <l -4x then the shaded portion would be on the left side )

remember again = if the slope is + then the shaded portion would be the way that the greater then sign is pointing

( y <l 4x then the shaded portion would be on the right side )

so the line that we are focused on would have the right side shaded which means that it would be a <l ,so the answer would be C

hope this helped you understand how to solve these a bit better!

Given the functions f(x) = x ^ 3, g(x) = 9 and h(x) = 2x , what is an expression equivalant to f(2x) + 3g(x)/h(x) + 3?

Answers

Answer:

an expression equivalent to f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

Step-by-step explanation:

As given ,

f(x) = x³ , g(x) = 9 , h(x) = 2x

Now,

f(2x) = (2x)³ = 2³.x³ = 8x³

⇒f(2x) = 8x³

Now,

[tex]\frac{g(x)}{h(x)} = \frac{9}{2x} = \frac{9}{2}x[/tex]

⇒[tex]3\frac{g(x)}{h(x)} = 3.\frac{9}{2}x = \frac{27}{2}x[/tex]

∴ we get

f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

The first snack is 270 calories for 3 servings, and the second snack is 450 calories How many servings does the snack have to have in order to equivalent to the first snack?

Answers

Answer:

5 servings

Step-by-step explanation:

Given that:

For a particular first snack  to be = 270 calories;

the servings = 3

Then, for the second snack, the calories = 450.

To estimate the servings for the second snack; we need to equate the first snack with the second snack.

Let y be the value of the unknown second snack

Then:

270 calories = 3 servings

450 calories = y servings

y servings = (450 calories × 3 servings) / 270 calories

y servings = 5 servings

Thus; the second snack needs to have 5 servings in order to be equivalent to the first snack
