each can of paint will cover 450 tiles. Augustin is painting 300 tiles in his bathroom, 675 in his kitchen, and 100 in his hallway. How many cans of paint does he need to buy?

Answers

Answer 1

Answer:

Answer:

He will need to buy 3 cans.

Step-by-step explanation:

First we need to know how many tiles he will paint.

The total amount of tiles he will paint is 300 + 675 + 100 = 1075 tiles.

We know that a can of paint will cover 450 tiles, therefore, we need to divide the total amount of tiles between the number of tiles covered by can:

1075/450 = 2.38.

He will need 2.38 cans of paint. But he cannot buy this number of cans, therefore he will have to buy 3 cans and will have some paint left.

Answer 2

Answer: You have to add all of the tiles that he needs painting. 675+300+100=1075. Then to figure out how many paint cans you need, divide 1075 by 450. It equals 2.388... so, you need to round up or else you will be missing some tiles. The final answer is 3 paint cans. Hope this helps

Cynthia is standing at the center of a circular playground. Which statement is true with respect to Cynthia’s position?

Answer: Out of all the options shown above the one that best represents the statement that is true with respect to Cynthia’s position is answer choice D) The distance from Cynthia to pole 3 is equal to the distance from Cynthia to pole 1. The reason being that it is the same as the radius of a circle. If you picture in your mind this analogy you will understand.

In basketball, Shaquille makes 40% of his free throw attempts. He goes to the free throw line to shoot one and one ( if he makes the first shot, he gets to shoot one more). He scores 1 point per free throw. What is the expected value of the number of points he will score?

Answers

Situations:
1) he makes 1st shot + he makes 2nd shot
P(A) = 0.4 · 0.4 = 0.16 ( 16 % )
2) he makes 1 st shot + he misses 2nd shot
P(B) = 0.4 · 0.6 = 0.24 ( 24 % )
3) he misses 1st shot and he has no more attempts
P (C) = 0.6 ( 60 %)
0.16 · 2 + 0.24 · 1 + 0.6 · 0 = 0.32 + 0.34 = 0.56
The expected value is 0.56 points.

.56 is the answer....
