If x and y are in direct proportion and y is 45 when xx is 15, find y when x is 4.

Answers

Answer:

y = 12

Step-by-step explanation:

the equation is

y = 3x

You find the constant or proportionality by put y/x

(15,45) is in the form (x,y)  The x is 15 and the y is 45.  Put this in the form y/x and you get 45/15 or 3.  3 is the constant of proportionality.

y = 3x

y = 3(4)

y = 12

y = 12

Length: 2 and 1 over 4 feet
Width: 1 foot
Height: 1 and 1 over 4 feet
The lengths of the sides of a small cube are 1 over 4 foot each.

Part A: How many small cubes can be packed in the rectangular prism? Show your work. (5 points)

Part B: Use the answer obtained in part A to find the volume of the rectangular prism in terms of the small cube and a unit cube. (10 points)

Answers

Answer: 84 cubes

Step-by-step explanation: Given, The dimension of the rectangular prism are, 1 1/3 ft. * 1 * 2 1/3 = 4/3 * 7/3 = 28/9 cube ft.

Now, the volume of a cube = side³, if side = 1/3 ft., Then the volume of each cube, V = (1/3)³ = 1/27 cube ft.

Hence, the number of cubes that can be packet in the prism = V/V1 = 28/9 / 1/27 = 27*28/9 = 3 * 28 = 84

A) The number of small cubes which can be packed in the rectangular prism are 180.

B) The volume of the rectangular prism in terms of the small cube and a unit cube will be 180 units³

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Length = 2 1/4 feet

Width = 1 feet

Height = 1 1/4 feet

And, The lengths of the sides of a small cube are 1 /4 foot each.

Now,

Since, The volume of rectangular prism = Length x width x height

Substitute all the values, we get;

⇒ The volume of rectangular prism = 2 1/4 × 1 × 1 1/4

                                                       = 9/4 × 1 × 5/4

                                                       = 45/16 ft³

                                                       = 2.81 ft³

And, The Volume of one cube = Side³

Here, The length of side of cube = 1/4 feet = 0.25 feet

Hence, The Volume of one cube = Side³

The Volume of one cube = 0.25³

The Volume of one cube = 0.015625 ft³

So, The number of small cubes that can be packed in the rectangular prism = Volume of rectangular prism / Volume of cube

         = 2.81 /0.015625

         = 180

B) The length, the width and the height of the rectangular prism in term of units cubes is:

Length = 2 1/4 feet / 0.25 feet = 2.25 / 0.25 = 9 units

Width = 1 feet / 0.25 feet = 4 units

Height = 1 1/4 feet / 0.25 feet = 1.25 / 0.25 = 5 units

So, The volume of the rectangular prism in terms of the small cube and a unit cube is,

Volume = 9 x 4 x 5

            = 180 units³

Answer:

250y = 800

Step-by-step explanation:

[tex]\frac{8}{250}[/tex] = [tex]\frac{y}{100}[/tex]  Cross multiply

250y = 800

Answer:

A)  250y = 800

Step-by-step explanation:

Given equation:

[tex]\dfrac{8}{250}=\dfrac{y}{100}[/tex]

Cross multiply by multiplying the numerator and denominator of the first fraction by the denominator of the second fraction, and multiplying the numerator and denominator of the second fraction by the denominator of the first fraction:

[tex]\implies \dfrac{8 \times 100}{250\times 100}=\dfrac{y \times 250}{100 \times 250}[/tex]

Simplify:

[tex]\implies 8 \times 100 = y \times 250[/tex]

[tex]\implies 800=250y[/tex]

We can rewrite this as:
5+6(4)
Since 6 is being multiplied by c, which is 4, and d=5
Now we can solve:
5+24
=29
6 times 4 is 24, and then you just have to add 5, which gets you 29.
Hope this helped!

Answer: 29

Step-by-step explanation: We first replace the variables with the numbers so it turns into 5 + 6 x 4 and according to the order of operations we do 6 x 4 first which is 24 and then we do 5 + 24 which is 29.

Write an inequality of the form Ax + B ≤ C to represent the word problem using your answers for A, B, and C. Solve the inequality and show your work.

A= $8
B= $10
C= $100

Answers

Since you have the values, just plug them into the inequality given.
8x + 10 <= 100
To solve the inequality, first get x by itself by subtracting 10 from both sides to get 8x <= 90, then divide both sides by 8 to get x <= 11.25
That means that whatever x is is no more than 11.25, but either less than or equal to it.
