Given is 1/2(10x+20y+10z)
Simplifying the given expression using Algebra properties.
Hence, the final answer would be (5x + 10y + 5z) or 5·(x + 2y + z).
Answer:
I'm so sorry I need the points
Step-by-step explanation:
Hope you understand
So in finding the area of the square where the part of the yard that is not covered, first is to calculate the are of both then subtract the two and the are for the circle is pi*r^2 so it means pi*(4x)^2 then for the are of square the formula is A^2 and its (20x)^2, and i think the best answer would be 20X^2-(pi*4x^2)
Answer:
30 PS4 in the shipment are likely to be defective
Step-by-step explanation:
We take the estimate from the sample and estimate to all the PS4 in store. This means that we can solve this question using a rule of 3.
From the sample of 50 PS4, 3 are defective. How many are expected to be defective out of 500?
50PS4 - 3 defective
500 PS4 - x defective
![50x = 3*500](https://tex.z-dn.net/?f=50x%20%3D%203%2A500)
![x = \frac{1500}{50}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1500%7D%7B50%7D)
![x = 30](https://tex.z-dn.net/?f=x%20%3D%2030)
30 PS4 in the shipment are likely to be defective
