Prime factorization of 20:-
2²×5
=20
Answer:
Amy worked 47 1/2 (47.5) hours
Step-by-step explanation:
(22.25) (40) = $890
1,173.50 - 890 = $ 283.50
283.50/37.80 = 7 1/2 hours
The small & large triangle are similar the we can write the following proportion/ratio:
8/(8+x) = 12/(12+18) ==> 12(8+x) =8(12+18) ==> 96+12x=240
12x =240-96 ==> 12x = 144 and x=12
Before we can determine the rectangular coordinate of the point, let's determine first its polar coordinates. For this, we need two things: radius and angle.
For the radius, we see that point R is 4 units away from the center.
For the angle, we see that it is 30° clockwise or 330° counterclockwise. See the illustration below:
Now that we know the radius is 4 units and the angle is 330° counterclockwise, let's now convert this to rectangular coordinates.
Use the formula below:
For x-coordinate, we have:


For the y-coordinate, we have:


Therefore, the rectangular coordinate of the given polar point is (2√3, -2). Option B.
Length = a
Width = (a - 10)
Height = (a + 10)
(a - 10) means that the width is 10 units less than the length of the rectangular prism.
The correct answer is D. The width of the rectangular prism is 10 units less than the length.
Hope this helps!! :)
