Answer:
27 hours
Step-by-step explanation:
Let her work "x" hours for paperwork
Since, patrolling amount of hours is THREE TIMES that,
Patrolling = 3x hours
Total Hours = 36
That is including paperhour work (x) and patrolling (3x). So we can setup an equation in x and solve for x first:
x + 3x = 36
4x = 36
x = 36/4
x = 9 hours
Amount of Hours for Patarolling = 3x hours = 3(9) = 27 hours
So, she spends 27 hours patrolling
Answer:
132, (D)
Step-by-step explanation:
area = base * height
= (5 + 6) * 12 = 11 * 12 = 132
Answer:
30, 66 and 84 degrees.
Step-by-step explanation:
The number of degrees in a triangle is 180 degrees.
Work out the 'multiplier':
It = 180 / (14+5+11)
= 180/30
= 6.
So the angles are:
14*6 = 84
5*6 = 30
11*6 = 66.
