Answer
1.15 hours
Step-by-step explanation:
Assuming 115 is 115 km then you just move the decimal point twice and get 1.15!
For example - (Starting number) 115. (Moving decimal point) 115. -> 11.5 -> 1.15
Answer:
4
Step-by-step explanation:
Let's call the width W and the length L.
We know the width is 3 less than the length, so:
W = L - 3
And we know the area is 28, so:
28 = WL
If we solve for L in the first equation:
L = W + 3
And substitute into the second equation:
28 = W (W + 3)
28 = W² + 3W
0 = W² + 3W - 28
0 = (W + 7) (W - 4)
W = -7, 4
Since W can't be negative, W = 4 units.
Answer:
6(72)= 432 & 8(74.25)=594
594-432=162==> 162-80=82
Answer:
1/3.
Step-by-step explanation:
2 x 6 = 12
1 2 3 4 5 6
1 2 3 4 5 6
4/12 = 1/3
4(5)+4(3)+3(2)=$38 total cost =$38
