Answer:

EF = 11

JK = 32

Step-by-step explanation:

Because the average of  10 and 12 is 11, therefore that would be the answer, since EF has a slite angle, finding the average of the largest side length and the opposite side would be the best way to find it.

Because the average of 28 and 36 is 32 your answer would be 32, this is from adding both lengths on LJ, which is 12 and 24, I added them to get 36, then found the average, the average was 36,  meaning that this was your answer.

Answer:

A. $ 58.50

B. $ 80

C. No, it did not mark up 30%

Step-by-step explanation:

Since,

A. We have,

Mark up percentage = 30%

Actual price = $ 45,

 B. We have,

SP = $ 104,

  C.  We have,

AP = $ 75,

SP = $100,

Thus, mark up percentage =  

= 33.33 %

Hence, store did not mark up the price by 30%.

Answer:

$ 72.80

Step-by-step explanation:

30% of 104 = 0.30 * 104

                  = $ 31.20

Money paid by the store = 104 - 31.20

                                         = $ 72.80

Answer:

1. [tex]-5-\sqrt{x}[/tex]

2. [tex]7+\sqrt{b}[/tex]

Step-by-step explanation:

The conjugate of a radical expression

[tex]a+\sqrt{b}[/tex]

is the expression

[tex]a-\sqrt{b}[/tex]

And vice-versa.

The conjugate is mostly used to rationalize radical expressions because the expression by its conjugate produces another expression without the radicals.

The question asks to find the conjugate of:

1. [tex]-5+\sqrt{x}[/tex]

The conjugate is

[tex]-5-\sqrt{x}[/tex]

2. [tex]7-\sqrt{b}[/tex]

The conjugate is

[tex]7+\sqrt{b}[/tex]

Answer:

5/6 - 1/6 = 4/6 = 2/3

Step-by-step explanation:

Since both numbers' denominators are the same, all you have to do is minus normally on the top numbers. You would take the difference and put it on the same denominators. Finally simplify!

Answer:

x+10-y

Step-by-step explanation:

i'm not 100% sure about this response, but i'd assume the answer is like this for the following reasons:

alex is x years old, and 10 years have passed, meaning 10 years are added onto his age (x+10). addison is still the same amount of years apart from him in age, so you subtract y from that (x+10-y).

Step-by-step explanation:

Given the expression for the equation representing the prediction of number of trucks as;

2/7 = t/54-t where t is the number of trucks

To get the number of trucks t, we will have to evaluate the expression and solve for t as shown;

Given 2/7 = t/54-t

Cross multiply

2(54-t) = 7t

Open the parenthesis

2(54)-2t = 7t

108-2t = 7t

7t+2t = 108

9t = 108

Divide both sides by 9

9t/9 = 108/9

t = 21

Hence the engineers should have counted 21trucks

Answer:

The answer is x = 0

Step-by-step explanation:

-7x - 8 = x - 8(1-5x)

Simplify and FOIL.

-7x - 8 = x - 8 + 40x

-7x - 8 = 41x - 8

Add 7x to both sides.

-8 = 48x - 8

Add 8 to both sides.

0 = 48x

x can only be 0 to multiply it by any other number and get 0.

x = 0

Answer:

x = -1

Step-by-step explanation:

-11 + 9(x+1) = 4(1+3x) - 3

9x + 9 - 11 = 12x + 4 -3

9x - 2 = 12x +1

-2 = 3x + 1

-3 = 3x

x = -1

Hope this helped

The value of  8/9/20 could be either 0.04 or 17.77.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, the fraction is the division of the two numbers but the division is not wholly complete.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Given the fraction,8/9/20

Case 01)

(8/9)/20 = 0.888/20 = 0.044.

Case 02)

8/(9/20) = 8/0.45 = 17.77.

Hence "The value of  8/9/20 could be either 0.04 or 17.77".

Answer:

Equilibrium quantity before the tax  = 40 units

Step-by-step explanation:

Given:

Qd = 240 - 5P

Qs = P

Computation:

Qd = 240 - 5P

P = 48 + Qd/5

Equilibrium quantity before the tax

Qd = 240 - 5P

P = 240 - 5P

6p = 240

p = 40

Qd = 240 - 5P

Qd = 240 - 5(40)

Qd = 40

Equilibrium quantity before the tax  = 40 units

Answer:

x = 1.25

Step-by-step explanation:
