Answer:
30420ft
Step-by-step explanation:
We have to break the shape into two. So..
13 times 26=338
now the top..23-13=10
10 times 9 = 90
338 times 90 = 30420 ft
8*(1/x) = 4*(1/8)
8/x = 4/8
64 = 4x
x = 16
I think X is 2. But I am not sure, cuz I don’t know what you teacher is really asking you to do.
1. Rational/The sum of two rationals is always rational
2. Irrational/ the sum of a rational and an irrational is always irrational
3. Irrational/The product of a nonzero rational and an irrational is always irrational
4. Rational/The product of two rationals is always rational
Pretty much all the irrational numbers are the ones with radical signs over them and the rational numbers are the fractions and whole numbers. Once you identify the two numbers to be rational or irrational, you can then find your answer within the second part of the answers.
Answer:
360 mi/h
Step-by-step explanation:
The speed for the outbound trip was ...
speed = distance/time = (715 mi)/(2 1/6 h) = 330 mi/h
The inbound speed was ...
(715 mi)/(1 5/6 h) = 390 mi/h
The airspeed of the plane is the average of these two ground speeds, so is ...
(330 +390)/2 = 360 . . . . mi/h
