Answer:

6.75

Step-by-step explanation:

first let's simplify whatever is inside the parantheses

8(2x-10)=28

8*2(x-5)=28

16(x-5)=28

now we divide both sides by 16 to get rid 16

x-5 = 28/16

now move -5 to the right side

x = 28/16 + 5

x = 28/16 + 80/16 = 108/16 = 6.75

First, distribute eight

16x - 80 = 28

Then, get x to be the only value on its side

16x = 108

Next, divide

x = 108/16

Finally, simplify

x = 27/4

A box with a square base and no top is to be made from a square piece of carboard by cutting 7 in. squares from each corner and

mojhsa [17]

Answer:

The size of the cardboard should be $26 in\ by\ 26in$

Step-by-step explanation:

The diagram for this question is shown on the first uploaded image

The volume of the box is $V = 2527 \ in ^3$

The length and the Width of the card is

L = W = Z

From the question we are told that 7 in squares were cut from each corner

So the length and the width of the box would be

L = W = (Z - 7)

And the height would be H = 7 in

Mathematically the volume of the box can be represented as

$V = Length\ of\ bx * Width\ of\ box * Height\ of\ box$

So the Volume would be

$V = (Z-7)(Z-7) * 7$

Substituting values

$(Z-7) ^2 = \frac{2527}{7}$

$(Z-7) ^2 = 361$

$(Z-7) ^2 = 19^2$

=> $Z - 7 = 19$

$Z = 19 + 7$

$Z =26 \ in$

You roll a standard number cube. Find P (number less than 4).

Serggg [28]

A standard number cube has 6 sides.

P is any number less than 4 (or 3,2, and 1).

3, 2, and 1 are 3 numbers

Place the number 3 over the amount of numbers there is.

3/6.

Simplify. Divide 3 from the numerator and denominator.

(3/6)/(3/3) = 1/2

1/2, or (B) is your answer

hope this helps!

Zoro Manufacturing Company manufacturers wooden picture frames. Each piece of wood yields 15 frames. Each piece of wood costs $1

sesenic [268]

To determine the cost of manufacturing one picture frame, add all the known cost by the number of frames produced. With the basis of one hour of operation,

Cost of wood per frame = $18.75 / 15 = $1.25

Cost of direct labor per frame = $ 13.50 / 65 = $ 0.21

Adding all up the costs,

total cost = $1.25 + $0.21 = $1.46

Therefore, manufacturing one picture frame costs approximately $1.46.
