Find the prime factors of each term in order to find the greatest common factor.

Step-by-step explanation:

a. The rate of change is $33.33 per month

200/6 = approximately $33.33 per month

This means that in addition to the initial fee, Josh has to pay $33.33 per month for the gym membership.

b. The initial value is $25. This is a constant value and a one time fee to open and attain a gym membership.

Answer:

a). 4 + 9x + 17 + 15x

b) 21 + 24x

Step-by-step explanation:

Here, we want to write expressions for the perimeter

Mathematically, this is the sum of the length of the sides

We have this as

a)

4 + 9x + 17 + 15x

b) = 4 + 17 + 9x + 15x = 21 + 24x

Answer:

2,600 male students

Step-by-step explanation:

[tex]\frac{2,400}{0.48} = 5,000[/tex]

There are 5,000 students in total.

Since 2,400 of them are female, the remaining students must be male.

5,000 - 2,400 = 2,600 male students

Answer: A

Step-by-step explanation:

Answer:

Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.Step-by-step explanation:

Answer:

-1/3

Step-by-step explanation:

hope it helps thanks

Answer:

-1/3

Step-by-step explanation:

Given:

The expression is:

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\_\_\_+\dfrac{1}{19}n\right)+\left(-8+\_\_\_\right)[/tex]

                                          [tex]=\_\_\_n+\_\_\_[/tex]

To find:

The missing values.

Solution:

We have,

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)[/tex]

It can be written as

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\dfrac{11}{19}n+\dfrac{1}{19}n\right)+\left(-8+10\right)[/tex]

So, the values for the first two boxes are [tex]\dfrac{11}{19}n[/tex] and 10 respectively.

On simplification, we get

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\dfrac{11+1}{19}n\right)+\left(2\right)[/tex]

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\dfrac{12}{19}n+2[/tex]

So, the values for third and fourth boxes are [tex]\dfrac{12}{19}[/tex] and 2 respectively.

Answer: [tex]15\times\frac{1}{2}[/tex]

Explanation:

Multiplying by 1/2 is the same as dividing by 2.

For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]

The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]

Answer:

108

Step-by-step explanation:

36 inches in a yard

12 inches in 1 foot, 3 feet in 1 yard.

12 * 3 = 36, 36 * 3 = 108

108 inches in 3 yards

Answer:

5/4

Step-by-step explanation:

36 is the 5tf power of 2 so we can rewrite the equation as

[tex] {2}^{4x} = {2}^{5} [/tex]

Since the expressions has same base the powers must be equal to

4x = 5 and x = 5/4

His average speed for the rest of the journey was of 48mph.

Answer:

(a) The possible dimensions are:

1 unit by 72 units;  2 units by 36 units;  3 units  by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units

(b): Patio with greatest and the least perimeter

The dimension with the greatest perimeter is: 1 by 72

The dimension with the least perimeter is: 8 by 9

Step-by-step explanation:

Given

[tex]Tiles = 72[/tex]

Solving (a): Possible rectangular models

To do this, we simply list out the possible factor pairs of 72.

So, we have:

1 unit by 72 units;  2 units by 36 units;  3 units  by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units

Solving (a): Models with the least and the greatest perimeter

Perimeter (P) is calculated using:

[tex]P = 2 * (L + W)[/tex]

So:

1 unit by 72 units;  

[tex]P = 2 *(1 + 72) = 146 units[/tex]

2 units by 36 units;  

[tex]P = 2 *(2 + 36) = 76 units[/tex]

3 units by 24 units;

[tex]P = 2 *(3 + 24) = 54 units[/tex]

4 units by 18 units;

[tex]P = 2 *(4 + 18) = 44 units[/tex]

6 units by 12 units;

[tex]P = 2 *(6 + 12) = 36 units[/tex]

8 units by 9 units

[tex]P = 2 *(8 + 9) = 34 units[/tex]

From the calculations above:

The dimension with the greatest perimeter is: 1 by 72

The dimension with the least perimeter is: 8 by 9

8*22 = 22*8

Hope this helps!

Answer:

3c = t

Step-by-step explanation:

3 cereal boxes is 3c and the total is t. so 3c = t

Answer:

3c = t

3 is the amount of boxes, c is the money, therefore, it is 3c=t, which means c times the number of boxes equals t
