Answer: H
Step-by-step explanation:
So this is called a problem you would use PEMDAS or (please-excuse-my-dear-aunt-sally)
Parenthesis
Exponents
Multiply
Divide
Addition
Subtract
In this sens, since parenthesis are present you do them first so it would be H
Complete question is: Each bicycle have speed 10 mi/h and fly flies at 21 mi/h. How far the fly flies?
Answer:
47.25 mi
Step-by-step explanation:
The relative velocity of the bicycles is 10+10 = 20 mi/h
Time in which the two bicycles meet:
Distance covered by fly:
10-6v+9v=28
10+3v=28
-10 -10
3v=18
3 3
v=6
Answer:
6.81m
Step-by-step explanation:
Using the formula for finding the length of am arc
L = theta/360° × 2πr
theta is the angle subtended by the drum in rotation
r is the radius of the drum
Given theta = 315.7°
r = 1.1m
Substituting the given values into the formula we have:
L = 315.7/360 × 2π(1.1)
L = 315.7/360 × 2.2π
L = 315.7/360 × 2.2(3.14)
L = 315.7/360 × 6.91
L = 6.81metres
Line of about 6.81metres will be wounded around the drum
The area of the wall is 92,322
