Okay the denominator stays the same. Add across the top 2+6= 8 . so put 8 over 11 and you can't simplify it is at its lowest term. 8/11

Four friends are told that the average (mean) of their grades in their favorite class was 88%

Kazeer [188]

First we have to find out the total. So we do 88 x 4 = 352 since it will give us the the total score when all of the scores are added.Then we add 74+94+86 which equals 254. And then 352 - 254 = 100 and that would be Ethan's score

Solve and express the solution set in simplest form.

oee [108]

Answer:

$\frac{11}{6}$

Step-by-step explanation:

The equation to be solve is

4x−1/3=7/1

We can go about this by first adding 1/3 to both sides.

$4x - \frac{1}{3} + \frac{1}{3} = \frac{7}{1} + \frac{1}{3}$

$\implies \ 4x = \frac{7}{1} + \frac{1}{3}$

We then simplify the the right hand side of the equation

$\implies 4x = \frac{21 + 1}{3}$

$\implies 4x = \frac{22}{3}$

To find x, we multiply through by 1/4

$\implies \frac{1}{4} \times 4x = \frac{22}{3} \times \frac{1}{4}$

$\implies x = \frac{22}{12}$

$\implies x = \frac{11}{6}$

Hence the solution set in the simplest form for the expression is

{x=11/2}

Aaron bought a new television that has a 92 in. 76 in. screen. It has a feature that splits the screen to allow him to watch 4 c

castortr0y [4]

Answer:

The scale factor is equal to 1/2

The dimensions of each channel when splits the screen is 46 in x 38 in

Step-by-step explanation:

we know that

The dimensions of the new television is 92 in x 76 in

Remember that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

A1 -----> the area of the new television

A2 ----> the area of each channel when splits the screen

z-----> the scale factor

$z^{2} =\frac{A2}{A1}$

we have that

The area of the new television is 4 times the area of each channel

$A1=4A2$

$(A2/A1)=1/4$

$z^{2} =\frac{1}{4}$

$z=\frac{1}{2}$ -----> the scale factor

When splits the screen, the dimension of each channel is equal to

92/2 in x 76/2 in

46 in x 38 in

Remember, if two figures are similar then the scale factor is equal to the ratio of their corresponding sides

<em>Verify the value of the scale factor</em>

92/46=1/2

76/38=1/2

There are 36 carpenters in a crew. On a certain day, 29 were present. What percent showed up for work? (Round to nearest tenth)

andreyandreev [35.5K]

To get this, We will need to divide 29 by 36.

29/36=.80555556

This means that about 80.5% Showed up for work.
