Answer: 56 degree
Step-by-Step Explanation:
Let measure of unknown angle be ‘x’
One angle = 68 degree
Sum of all angles is 180 => 68 + 2x = 180
Therefore,
68 + 2x = 180
2x = 180 - 68
2x = 112
x = 112/2
=> x = 56
Therefore, the measure of the missing angles is 56 degrees each.
Answer:
64=boys
Step-by-step explanation:
Boys to girls
4:5
80=girls
80÷5=16×4=64
Answer:
11.46 I believe
Step-by-step explanation:
N = number of hours.
$5 per hour, total = 5*n = $5n
Since $35 has been saved.
The amount saved plus the amount got from baby sitting should be greater or equal to the $90 cost.
5n + 35 ≥ 90
5n ≥ 90 -35
5n ≥ 55
n ≥ 55/5
n ≥ 11
So Rodney should baby sit for at least 11 hours, that is 11 and above.
Answer:
V = 882pi units^3
or approximately
2769.48 units^3
Step-by-step explanation:
The column of a cylinder is given by
V = pi * r^2 * h
We know the radius is 7 and the height is 18
V = pi * 7^2 *18
V =pi *49 *18
V =882 pi
If we want an approximate answer, we can approximate pi by 3.14
V = 3.14 * 882
V =2769.48
