Answer:
12.9 hours.
Step-by-step explanation:
First, do 2.15 hours multiplied by 2, for each day. Then, multiply 4.30 by the 3 for 3 weeks.
Answer:
Step-by-step explanation:
You need to divide 250 by 2.205 and get 113.398 if you estimate it your answer will be 113
Let a, b and c be 3 numbers whose Greatest Common Factor is 13.
This means that all a, b, and c are multiples of 13, and the three of them have no other common factor (except1)
So we can construct a, b and c as follows:
a=13*2*3, b=13*2*5, c = 13*7
a=78, b=130, c=91
Answer: {78, 130, 91}
Answer:
225 ft^2
Step-by-step explanation:
From what we have in the question, we have 60 ft of fencing
To maximize the area, we will need to have a square
For a square, the length of all sides are equal
Let us call one of the sides s
Thus, from the perimeter of the square;
4s = 60
s = 60/4
s = 15 ft
The area is thus, the product of the side length of the square
15 * 15 = 225 ft^2
Answer:
40
Step-by-step explanation:
40 because since we know c is 25 and b is 65 we have to subtract 25 from 65 and get 40
