Answer:
P = -30
Step-by-step explanation:
first, you need to move the virable to one side:
3/4P - 4/5P = 3/2
second, you make the denominator the same:
15/20P - 16/20P = 3/2
-1/20P = 3/2
third, you will divide it both side of -1/20:
-1/20 -:- -1/20P = 3/2 -:- -1/20
P = 3/2 x -20/1
P = -60/2
P = -30
Answer:
156
Step-by-step explanation:
Let the sum of the set of numbers = S
So....the mean would be calculated as the sum of the set divided by its number of entries, or :
S / 12 = 13 ....... multiply both sides by 12
S = 13 * 12 = 156 .....so.....the sum is 156
Answer:
151
Step-by-step explanation:
tan 40° = x/180
tan 40°*180 = x
0.8391*180 = 151
height = 151m
If the measure of central angle is 3π /4 radians, then the area off the shaded sector is 96π square units
The radius of the circle = 16 units
The central angle of the shaded region = 3π /4 radians
The area of the sector = (θ/ 360) × πr^2
Where θ is the central angle of the sector
r is the radius of the sector
Substitute the values in the equation
The area of the sector = ((3π /4) /360) × π × 16^2
Convert the radians to the degrees
= (135/360) × 256π
Multiply the terms
= 96π square units
Hence, the area of the shaded sector is 96π square units
