It's 20, the answer is 20.

Given:

A right rectangular prism is packed with cubes of side length [tex]\dfrac{1}{5}[/tex] inch.

Prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height.

To find:

The volume of the prism

Solution:

Side length of each cube [tex]=\dfrac{1}{5}[/tex] inch.

15 cubes along the length, so length of prism is

[tex]l=15\times \dfrac{1}{5}=3\text{ inches}[/tex]

6 cubes along the width, so width of prism is

[tex]b=6\times \dfrac{1}{5}=\dfrac{6}{5}\text{ inches}[/tex]

5 cubes along the height, so height of prism is

[tex]h=5\times \dfrac{1}{5}=1\text{ inch}[/tex]

Now,

Volume of rectangular prism is

[tex]V=l\times b\times h[/tex]

[tex]V=3\times \dfrac{6}{5}\times 1[/tex]

[tex]V=\dfrac{18}{5}[/tex]

[tex]V=\dfrac{3\times 5+3}{5}[/tex]

[tex]V=3\dfrac{3}{5}\text{ cubic inches}[/tex]

Therefore, the correct option is B.

Answer:

x = -2

Step-by-step explanation:

Step 1: Write equation

2(x - 6) + 6 = 4x - 2

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

2(-2 - 6) + 6 = 4(-2) - 2

2(-8) + 6 = -8 - 2

-16 + 6 = -10

-10 = -10

Answer:

distribute the 2. add -12+6. add 2 to both sides. decide both sides by 2. x= -2

The coordinates of the image of the point (4,5) after reflecting over the

the y-axis is (- 4, 5).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, A point (4, 5) is reflected over the y-axis.

We know points of coordinated (x, y) reflected over the x-axis becomes

(- x, y).

Therefore, The coordinate points (4, 5) after reflecting over the y-axis would be ( - 4, 5).

Answer: 6 cups of ketchup per cup of mustard

Step-by-step explanation:

Given : The recipe calls for 3 cups of ketchup for every [tex]\dfrac12[/tex] cup of mustard.

That means , for [tex]\dfrac12[/tex] cup of mustard. we need 3 cups of ketchup.

By using proportions, if we multiply 2 on both sides ,we get

for  [tex]\dfrac12\times 2[/tex] cup of mustard. we need [tex]3\times 2[/tex] cups of ketchup.

⇒ for  [tex]1[/tex] cup of mustard. we need [tex]6[/tex] cups of ketchup.

Hence, the required rate = 6 cups of ketchup per cup of mustard

The  rate in cups of ketchup per cup of mustard is 6.

Given that,

Based on the above information, the calculation is as follows:

Answer:

4

Step-by-step explanation:

the number before x is the slope

^^^^^^^^^^^^^^^^^^^^^^^^

The equation is y = mx + b. b is the y intercept, which means the line intersects the y axis at 50, not the x axis. Also, the equation is an inequality and you wrote an equation. The inequality should be 100 ≥ 4x + 50, or 50 ≥ 4x. If y = 4x + 50, then 100 ≥ y.

Also, in the end you got 12.5. 12.5 is not a number of people that can attend her party. The number has to be a positive integer.

Usually, inequalities are graphed with shading up or down. In this case it is down because you have a limit on how much Gamora can spend.

The actual answer is 12 people.

Your answer was almost right if only you had converted it to the greatest positive integer less than 12.

Your graphing was wrong because you put 50 as the x intercept instead of the y intercept, and you forgot to shade. The question tells you to graph an inequality.

Answer:

The answer is

[tex] \huge y = \frac{5}{3} x - 4[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)\\[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (6,6) and slope 5/3

We have

[tex]y - 6 = \frac{5}{3} (x - 6) \\ y - 6 = \frac{5}{3} x - 10 \\ y = \frac{5}{3} x - 10 + 6 \\ [/tex]

We have the final answer as

[tex]y = \frac{5}{3} x - 4 \\ [/tex]
