Step-by-step explanation:

To be honest I really just started with a common number I've seen in these types of problems (35) and that was not enough so I kept using numbers from 35 to 50. For the problem you just multiply 4 by the same number you multiply 5 by and then add the same number hope that makes sense.

Step-by-step explanation:

First of all, write the values of x and y respectively. Then do the DMAS. When there is equal to sign between two numbers then you can bring on number to the other side of equal to sign with the sign changed. Then you get your answer

Answer:

When x= 3, then y= 1/3 and When y= 5, then x= 45

Step-by-step explanation:

3 = 9y

3/9 = y

1/3 = y

and

x = 9 * 5

x = 45

980 feet per minute

Step-by-step explanation:

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

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]

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

Answer: 27

Answer:

The height of the plant is 76 cm after 24 months.

Step-by-step explanation:

Here, we know that on each month 1 cm every month so it's increased 24 cm after 24 months

Therefore

H = 52 + m

H = 52 + 24

H = 76 cm

Thus, The height of the plant is 76 cm after 24 months.

Answer:

[tex]y = 6[/tex]

Step-by-step explanation:

[tex]6(y + 15) = 126 \\ y + 15 = 21 \\ y = 21 - 15 \\ y = 6[/tex]

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.

Answer:

Step-by-step explanation:

order of operations parentheses first!

so 4(6k+4) = (4x6)k + (4x4)

which gets you to

5k + 24k + 16 - 29k = 16

simplified down to

29k + 16 -29k = 16

the answer is 16 = 16 the 29k’s cancel out

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

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
