Answer:

A can paint in 3days and B in 6 days

Step-by-step explanation:

From the question we were told

Person A can paint the neighbors house 2 times as fast as Person B

Let A only paint the neighbors house in X days

Let B only paint the neighbors house in 2X days

If we express the given information from the question in terms of fraction we have,

1/X + 1/2X = 1/2

3/2X = 1/2

if we cross multiply we have

6= 2X

X= 6/2

X= 3

Then A can paint the house in 3 days and B in 2(3)= 6days.

Use the graph to estimate the height of a jugglers ball that has been in the air for 1.5 seconds

strojnjashka [21]

Answer:

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

Step-by-step explanation:

we are given height equation as

$h=-16t^2+25t+5$

where

h is the height in feet of a Juggler's ball after t seconds

now, we can plug t=1.5

$h=-16(1.5)^2+25(1.5)+5$

we can solve for h

$h=42.5-16\cdot \:1.5^2$

$h=42.5-36$

$h=6.5$

So,

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

Help solve for r algebra

bija089 [108]

Answer:

$\frac{20}{7}$

Step-by-step explanation:

Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

$7r=4(5)$

Simplify: $7r=20$

Divide both sides of the equation by 7 to get: $r=\frac{20}{7}$
