what's the width of the base of a rectangle if the length is 70ft less than twice the width and the perimeter is 760

schepotkina [342]

Answer:

Let width be x ft

Length=2x-70 ft

Perimeter=760ft

Perimeter=2(x+2x-70)

760 ft=2(3x-70)

380ft=3x-70 ft

450ft=3x

x=450/3

x=150ft.

Can someone please help me!!!!!!!!!!!!!!!!!!!!!

N76 [4]

Answer:

5x-6+7x+12=180

Step-by-step explanation:

5x+7x = 12x

12x - 6 +12 = 180

add 12 and -6 to get 6.

12x + 6 = 180

subtract 6 from both sides to get 174.

12x = 174.

now divide both sides by 12 to get x = 14.5 or 29/2 which cancels out to 6

A population has a mean µ = 6 and ∑x = 48. How many scores are in the population?

maks197457 [2]

Answer:

Step-by-step explanation:

Recall the formula for the population mean of a data set:

$\mu=\frac{\sum x}{N}$

We already know that μ is 6 and the sum is 48. Substitute:

$6=\frac{48}{N}$

Divide both sides by 48:

$\frac{1}{8}=\frac{1}{N}$

Reciprocal of both sides:

$N=8$

Thus, there are 8 scores in the population size.

And we're done!
