Patrick will be able to paint the home on his own after a ten-hour effort.

This is further explained below.

<h3>How much time will it take for Patrick to paint the house by himself?</h3>

Generally, the equation for time is  mathematically given as

1/(t+4)  +  1/(t+9)  = 1/t

Therefore

[1/(t+4)] (t+4)(t+9)(t) +  [1/(t+9)](t+4)(t+9)(t) =  (1/t)(t+4)(t+9)(t)  

(t² + 9t)  + (t² + 4t) = t² + 13t + 36

Place the equation on the left side of the page and make it equal to 0. Use the additive inverse property as follows:

t² + t² - t² + 9t + 4t - 13t - 36 = 0

2t² - t² + 13t - 13t - 36 = 0

t² - 36 = 0

Calculate the product of the difference of two squares using the formula t2 - 36 = 0.

Both the total and the difference between the two terms constitute the factors.

(t + 6) (t - 6) = 0

t + 6 = 0

t = -6

t - 6 = 0

t = 6

Choose the positive value for time, t = 6 hours.

It will take 10 hours for Patrick to paint the house alone.

Patrick will be able to paint the home on his own after a ten-hour effort.

Whats the soultion for 10000 ft/hr = mi/hr
VLD [36.1K]
Hi! There are 5,280 feet in a mile. Therefore, you need to divide 10,000 feet by 5,280 (to see how many miles there are per every 5280 feet) and you get 1.89 miles per hour.

Solve this problem. What is x?
DedPeter [7]

a^2 + b^2 = c^2

a^2 = 6^2 + √117^2

a^2 + 36 = 117

a^2 = 117 - 36

a^2 = 81

a = √81

a = 9

x = 9
