Answer:
Time required by Ben was 12 minutes.
Step-by-step explanation:
Given:
Time Required for Fred = 16 mins
Ben completed his run in 3/4 of the amount of time of Freds run.
We need to find the time required by Ben.
Now Given that;
Ben completed his run in 3/4 of the amount of time of Freds run.
It means that time required by Ben is equal to 3/4 times time required by Fred.
Time required by Ben = 
Time required by Ben = 
Hence Time required by Ben was 12 minutes.
Answer:
5 and 7.
Step-by-step explanation:
Hey! So to start you need to create an algebraic expression. You can express this problem through the following equation:
*Note: if x is an odd integer, x + 2 is the next consecutive odd integer.

Expanding, you get:

And moving the 35 to the other side, you get a simple quadratic.

Solving by factoring:

This means two possible solutions for the smaller consecutive number are -7 and 5. However the question asks for two positive odd integers, so one of the numbers must be 5. The next will be 7(as its x + 2).
30?
30pi = 2pi r
30pi / 2pi = 15
15 = r

Answer:
Step-by-step explanation:
Area = 42x + 56
length * width = 14* 3x + 14*4
14 * width = 14*(3x+4)
