You would do the whole perimeter (the length of all the sides added up) minus the three known sides to find the missing side.
20 - 4 - 4 - 8 = 4, so the answer would be 4 inches.

When finding perimeter you add all the sides up.
So if you're looking for the perimeter, which is 20, just add 8 + 4 + 4
That equals 16.
So do 20 - 16.
Then you get your answer which is 4 in

You could also do:
20-8
That's 12
Then 12-4
That's 8
Then do 8-4
To get you your answer of 4 in

Felix scored 52 and 64 on his first two test in Sociology 212. What must he get on the third test to get an average of the three
Pie

Answer:

Felix's third test score must be greater than 94

Step-by-step explanation:

Felix scores on Sociology 212 tests:

1st test - 52

2nd test - 64

3rd test - x

Find the average of Felix's scores:

\text{Average}=\dfrac{\text{The sum of all scores}}{\text{The total number of scores}}\\ \\\text{Average}=\dfrac{52+64+x}{3}

An average of the three test must be above 70, this means

\text{Average}>70\\ \\\dfrac{52+64+x}{3}>70

Solve this inequality. First, multiply it by 3:

52+64+x>210\\ \\x>210-52-64\\ \\x>94

an aeroplane is flying with a help of 300 km per hour who much distance will it cover in 160 minute ​
uysha [10]

Answer:

800 km

Step-by-step explanation:

Does the plane have a speed of it's own?  I don't see it, so will assume the plane is simply travelling at 300 km/h.

(300 km/hr)*(1 hr/60 min) = 5 km/min

(5 km/min)*(160 min) = 800 km in 160 minutes
