Answer:

<h2>Q 11. A and E</h2><h2>Q 12. A</h2><h2>Q 13. 4/3 cups of sugar</h2>

Step-by-step explanation:

The points (1, 3) and (15, 45) are proportional to point (3, 9) since they correspond with each other so if you multiply the point (1, 3) by a factor of 3, it would be (3, 9). If you divided the point (15, 45) by a factor of 5, it would be (3, 9).

In this equation, 2.95 represents the price of the gallons since it is being multipied by g, or the number of gallons.

If you were to multiply 2/3 cup of sugar and 1/2 cup of flour by 2, I would get 4/3 cups of sugar and 1 cup of flour. Why did I do this? Well, she uses 1 cup of flour so you can divded 1 by 1/2 is which 2.

Hope this helps, you can ask me why certain choices were not correct if you'd like.

See the explanation

<h2>Explanation:</h2><h2></h2>

Here we have the following points:

$(3,9) \ and \ (-3,-9)$

The point-slope form of the equation of a line is:

$y=ax+b \\ \\ \\ a:Slope \\ \\ b:y-intercept$

So the slope can be found as:

$a=\frac{-9-9}{-3-3} \\ \\ a=\frac{-18}{-6} \\ \\ a=3$

So:

$y=3x+b \\ \\ \\ Finding \ b: \\ \\ For \ x=3, \ y=9: \\ \\ \\ So: \\ \\ 9=3(3)+b \\ \\ b=9-9 \\ \\ b=0$

So the equation is finally:

$y=3x$

This line passes through and is shown below.

Justin has a crate that is 8 feet long 2 feet wide and 3 feet tall decide weather each of the crate sizes described below has th

Nuetrik [128]

Complete question is;

Justin has a crate that is 8 feet long, 2 feet wide, and 3 feet tall. Decide whether each of the crate sizes described below has the same volume as Justin’s crate.

a. 9 feet long, 1 foot wide, 4 feet tall

b. 8 feet long, 2 feet wide, 2 feet tall

c. 4 feet long, 4 feet wide, 3 feet tall

d. 8 feet long, 3 feet wide, 3 feet tall

e. 6 feet long, 2 feet wide, 4 feet tall Answer:

Options C & E have the same volume as Justin's crate.

Step-by-step explanation:

We are told Justin has a crate that is 8 feet long, 2 feet wide, and 3 feet tall.

Thus, original volume is;

V_o = 8 × 2 × 3 = 48 ft³

A) For a dimension of 9 feet long, 1 foot wide, 4 feet tall , volume is;

V_a = 9 × 1 × 4 = 36 ft³

B) For a dimension of 8 feet long, 2 feet wide, 2 feet tall, volume is;

V_b = 8 × 2 × 2 = 32 ft³

C) For a dimension of 4 feet long, 4 feet wide, 3 feet tall, volume is;

V_c = 4 × 4 × 3 = 48 ft³

D) For a dimension of 8 feet long, 3 feet wide, 3 feet tall, volume is;

V_d = 8 × 3 × 3 = 72 ft³

E) For a dimension of 6 feet long, 2 feet wide, 4 feet tall, volume is;

V_e = 6 × 2 × 4 = 48 ft³

Looking at all the options, the only ones that given a volume equal to Justin's original volume are options C & E.

Find the height of a cylinder with a volume of 1408 cubic feet and a radius of 8 feet

storchak [24]

Height of cylinder = h = 7.006 feet

Step-by-step explanation:

<u>We are given:</u>

Volume of cylinder = 1408 cubic feet

Radius = 8 feet

Height of cylinder = ?

<u>Formula used:</u>

$Volume = \pi r^2h$

Putting values in the formula and finding height:

$Volume = \pi r^2h\\1408=3.14*(8)^2*h\\1408=3.14*64*h\\1408=200.96*h\\h=\frac{1408}{200.96}\\h=7.006\,\,feet$

So, Height of cylinder = h = 7.006 feet

F(ə) =

barxatty [35]

Answer: To get function g, shift f DOWN by 7 units and to the RIGHT by 2 units

Step-by-step explanation: g(x)= (x-2)^2-7 since they’re both negatives it should be the opposite. An example would be g(x)=(x+3)^2+5, f goes UP for positive by 5 units, left by 3 units.

What is the sum of 9 7/8 plus 11 2/8?

slamgirl [31]

Answer:

169/8

Step-by-step explanation:

9 7/8 = 79 / 8

11 2/8 = 90 / 8

90/8 + 79/8

The denominator (8) stays the same

90+79 = 169

169/8 or 21 1/8
