Answer: -4860y^2
Solution:
81 x (5y x 6) x (-2y)
-81 x 5y x 6 x 2y
= -4860y^2
Answer:
G
Step-by-step explanation:
First off, we know that Trinity is allowed to watch 420 minutes of television a week, which means that her watch time can be=420, cannot be >than 420 minutes, and can be <than 420 minutes. (in other words, her watch time can be equal to or less than 420 minutes) Because of this, we know that our answer choice must have 420≥. So H and J are out of the question.
Also, we know that each show that she watches is 30 minutes long. Because of this, the next part of our answer is going to be 30s. (I will explain this in the comment section of my post because it's getting a little long)
Therefore, the answer is G: 30s≤420
Equation is 25x + 100 is greater than or equal to 700. First subtract 100 from 700. Then divide 600 by 25 = 24. Sharon must Sell greater than or equal to 24 items
1614 divided by 4 is 403.5
The area of the circle = π r² = π (d/2)²
Where r is the radius of the circle
And d is the diameter of the circle
d = 2r OR r = d/2
given d = 10 in ∴ r = d/2 = 10/2 = 5 in
∴ The area of the circle = π r² = π * 5² = 25π ≈ 78.54 in²
The correct answer is the fourth option 78.54
==========================================
very important note:
There is a mistake in the dimension of the answers.
The dimension of the given diameter is inch , while the dimensions of the answers is square cm.
If it is required to find the area in square cm
∵ 1 inch = 2.54 cm
∴ r = d/2 = 10/2 = 5 in = 5 * 2.54 cm = 12.7 cm
∴ Area = π r² = π * (12.7)² = 161.29π ≈ 506.7 square cm
