Answer:

tbh im no t so good with stuff like this in the morning so but i got this How do you calculate sales growth? To start, subtract the net sales of the prior period from that of the current period. Then, divide the result by the net sales of the prior period. Multiply the result by 100 to get the percent sales growth.

Step-by-step explanation:

if this helps a bit lmk and have a brilliant day with a smile :D

Please help me and show how you worked out.

sdas [7]

Answer: The sequence rule is division. 80 divided by 2 = 40 divided by 2 = 20 divided by 2 = 10 and 10 / 2 equals 5.

Step-by-step explanation:

The sequence is divided by 2 because when you divided 80 by 2, it equals the second pattern in the sequence, 40.

I worked it out by dividing every number by 2 and getting the same numbers in the pattern, I checked by doing the opposite, 40 x 2 = 80.

Hope this helps!

Divide and simplify.

vredina [299]

Answer:

$\frac{ {x}^{2} + 10x + 16 }{ {x } {}^{2} + 6x + 8} \div \frac{1}{x + 2}$

$\frac{ {x}^{2} + 8 x+ 2x + 16}{ {x}^{2} + 4x + 2x + 8} \times (x + 2)$

$\frac{x(x + 8) + 2 (x + 8)}{x(x + 4) + 2(x + 4)} \times (x + 2)$

$\frac{( x + 8)(x + 2)}{(x + 2)(x + 4)} \times ( x + 2)$

$\frac{( x + 8)(x + 2)}{(x + 4)}$

7. Which of the following can be determined from the graph below?

Answer:

The ordered pair (6,25) is a solution to both

$y=-\frac{5}{2}x+40$ and $y=\frac{5}{3}x+15$

Step-by-step explanation:

Part 7)

step 1

Find the equation of the line with positive slope

take the points (0,15) and (9,30)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{30-15}{9-0}$

$m=\frac{15}{9}$

simplify

$m=\frac{5}{3}$

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=\frac{5}{3}$

$b=15$

substitute

$y=\frac{5}{3}x+15$

step 2

Find the equation of the line with negative slope

take the points (0,40) and (8,20)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the given values

$m=\frac{20-40}{8-0}$

$m=-\frac{20}{8}$

simplify

$m=-\frac{5}{2}$

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=-\frac{5}{2}$

$b=40$

substitute

$y=-\frac{5}{2}x+40$

step 3

Find the solution of the system

we know that

The solution of the system of equations is the intersection point both graphs

The intersection point is (6,25) ----> see the graph

therefore

The ordered pair (6,25) is a solution to both $y=-\frac{5}{2}x+40$ and

$y=\frac{5}{3}x+15$

Hi can you help me to answer this?

Lemur [1.5K]

Answer:

1) 85

2) 150

Step-by-step explanation:

The measure of a minor arc is EQUAL to the central angle

"The measure of a minor arc is equal to the measure of the central angle that intercepts the arc. We can also say that the measure of a minor arc is equal to the measure of the central angle that is subtended by the arc."
