Answer:

The answer is 1/2 an hour

Step-by-step explanation:

First, you know that in 1/4 of an hour, you paint 1/2 of the wall
Since we know that it took them 1/4 of an hour to paint half of the wall, to paint the other half of the wall it would also take 1/4 of an hour
Then, 1/4 + 1/4 = 2/4
So it takes 2/4 of an hour to finish painting one wall.
Lastly, you can reduce 2/4 to 1/2

So your final answer is 1/2 hour

c) area of a square = (base X width) = 11 X 11 - 121 yds sqaured

d) are of a trapezoid (the hardest) =

Help Q-Q 7/10c =4 1/5

shepuryov [24]

$\huge\mathfrak\green{answer}$

$= q - \frac{q7}{10} c = \frac{41}{5}$

$\red{multiply}$

$= q - \frac{cq7}{10} = \frac{41}{5}$

$\red{subtract \: q \: from \: both \: sides}$

$= q - \frac{cq7}{10} - q = \frac{41}{5} - q$

$\red{now \: simplify}$

$= - \frac{cq7}{10} = \frac{41}{5} - q$

$\red{multiply \: 10 \: both \: sides}$

$= 10( - \frac{cq7}{10} ) = 10. \frac{41}{5} - 10q$

$\red{simplify}$

$= - cq7 = 82 - 10q$

$\red{now \: divide}$

$= \frac{ - cq7}{ - q7} - \frac{82}{ - q7} - \frac{10q}{ - q7}$

$\red{simplify}$

$= c = - \frac{82 - 10q}{q7} (q≠0)$

Brainliest? :) (I'd really appreciate if you mark me as brainliest)

A stream is flowing down a slope into a larger river. The elevation of the head of the stream is 1,776 feet above sea level. The

ddd [48]

Answer:

-167.2 ft/mile

Step-by-step explanation:

The "rise" is 1298 -1776 = -478 ft. The run is given as 15,098 ft, so the slope is ...

slope = rise/run = -478/15098 ≈ -0.0316598

For 5280 feet in 1 mile, that rate of change amounts to ...

-0.0316598×5280 ft ≈ -167.2 ft . . . per mile
