Dr. Al-Islam teaches the football team 4 new plays in 2/5 of a practice. How many new plays can he teach them in one practice?

1 answer:

4 0

10 plays

Divide 2/5 and 4 by 2 to get 1/5 and 2

For every 1/5 of practice he teaches the ten 2 plays

5/5 = 1

So 5*2 = 10 plays

Lee has 3 children, the oldest is twice as old as the oungest, the middle is 5 years older than the youngest, the sum of the chi

tangare [24]

Oldest = 2x
Middle = x + 5
Youngest = x

2x + x + 5 + x = 57
combine like terms

4x + 5 = 57
subtract 5 from both sides

4x = 52
divide both sides by 4 to isolate x

x = 13

Oldest = 2x = 2(13) = 26
Middle = x + 5 = 13 + 5 = 18
Youngest = x = 13

Write an expression equivalent to h^6/h^3 in the form of h^m

Pavel [41]

Answer:

$h^3 = h^m$

Step-by-step explanation:

$\frac{h^6}{h^3} = h^m$

6 - 3 = 3

keep the base same, therefore

$h^3 = h^m$

Hope this helps!

Hey everyone. I need the answer to this ASAP!: Michael knows that 2 cans of paint is the exact amount he needs to paint a 10-foo

Ivahew [28]

Answer:

See attachment for graph

Step-by-step explanation:

Given

$2 cans = 10ft\ by\ 12ft$

Required

Graph the relationship between both parameters

First, calculate the area;

$Area = 10ft * 12ft$

$Area = 120ft^2$

This implies that: (2, 120) i.e. 2 cans for 120ft^2.

So we have:

(0,0) and (2,120)

(0,0) implies that: 0 cans for 0 square feet

Calculate the slope:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{120 - 0}{2-0}$

$m = \frac{120 }{2}$

$m = 60$

The equation is:

$y = m(x - x_1) + y_1$

So, we have:

$y = 60 * (x - 0) + 0$

$y = 60 * (x )$

$y = 60 x$
