Barry found a computer at Staples for $989. A week later, the computer went on sale for $849. What

JulijaS [17]

Barry found a computer at Staples for $989. A week later, the computer went on sale for $849. The percentage change is 14.156 % decrease

Solution:

Given that Barry found a computer at Staples for $989

A week later, the computer went on sale for $849

To find: percent of change

Percent change is the extent to which a variable gains or loses value. The figures are arrived at by comparing the initial (or before) and final (or after) quantities according to a specific formula.

THE PERCENT CHANGE IS GIVEN AS:

$\text{ percent change } =\frac{\text { final value - initial value }}{\text { initial value }} \times 100$

If the result is positive, it is percentage increase

If the result is negative, it is percentage decrease

Here initial value = 989 and final value = 849

Substituting the values in above formula,

$\begin{aligned}&\text { percent change }=\frac{849-989}{989} \times 100\\\\&\text { percent change }=-0.14155 \times 100=-14.156 \%\end{aligned}$

Here negative sign denotes percentage decrease

Thus percentage change is 14.156 % decrease

Please explain the steps on how to solve it! (Answer is selected)

LenKa [72]

Answer:

5x - 2y = -10 (B.) This should be right so if its not let me know I am stumped on what else it would be

Step-by-step explanation:

Parallelism: Same slope but different y-intercept

1 - Get into slope formula

5x - 2y = 7

- 5x -5x

-2y = -5x + 7

-2y/-2 = -5x/-2 +7/-2

y = (5/2)x - 7/2

2 - Plug x and y from (0, 5) into y = mx + b however note the - 7/2 is extranneous and wont be used for b

y = (5/2)x + b

5 = (5/2)0 + b

5 = 0 + b

5 = b

Therefore

y = 5/2x + 5 is your slope formula.

Now to get x to the other side.

3 - Get it back to standard form.

y = 5/2x + 5

- 5/2x -5/2x

- 5/2x + y = 5

(Multiply 2 into everything to get rid of the fraction)

-5x + 2y = 10

An end point of a line segment is (-10, -2) and the midpoint of the line segment is (0,4). Find the other endpoint.

Dovator [93]

Answer: The other endpoint is (10,10)

Step-by-step explanation:

$\frac{-10 + x }{2} =0$

-10 +x = 0

+10 +10

x= 10

$\frac{-2 + y}{2} =4$

-2 + y = 8

+2 +2

y =10

The pentagon below has an area of 8.3 square centimeters and a side of 2.2. What is the approximate length of the apothem? A.0.4

nalin [4]

Answer:

C. 1.5 cm

Step-by-step explanation:

A pentagon is a polygon with 5 sides.

The formula for the area of a regular polygon is

$A=\frac{1}{2}ap$

where a is the apothem and p is the perimeter. The perimeter is found by multiplying the number of sides of the figure by the length of 1 of those sides:

5(2.2) = 11

Now we have everything we need to solve for the length of the apothem.

$8.3=\frac{1}{2}a(11)$

Begin by multiplying both sides by 2 to get rid of the fraction, so

16.6 = 11a Divide both sides by 11 to get

a = 1.5090909 or

C. 1.5 cm

7+2|x+5|=11 then what is the solution set

Thepotemich [5.8K]

Answer:

x = -3 and x = -7

Step-by-step explanation:

7 + 2(x+5) = 11

7 + 2x + 10 = 11

2x + 17 = 11

2x = -6

x = -3

7 + -2(x+5) = 11

7 + (-2x) + (-10) = 11

-3 -2x = 11

-2x = 14

x = -7
