Step-by-step explanation:
any rational number can be expressed as a/b, with a and b being integer numbers, and b different to 0.
-7 = -7/1 rational
sqrt(10) irrational (because there is no rational number multiplied by itself that results in 10)
sqrt(16) = sqrt(4×4) = 4 = 4/1 rational
52% = 52/100 rational
1.235 = 1235/1000 rational
So here is the answer. Initially, Ed's toy cars compared to Pete's toy cars was 5:2. So for every 5 cars that Ed has, Pete has 2. Now that Ed gave 30 cars to Pete. So here it goes. The total number of ratio units is 5+2=7, so each will have an equal number if they both have 3.5 ratio units. That is, if Ed transfers to Pete 1.5 ratio units, their car counts will be equal. Thus 1.5 ratio units = 30 cars, or 1 ratio unit = 20 cars. Therefore, this makes <span> 7*20 cars = 140 cars.

Answer:
D.
{ (1, 3), (2, 3), (3, 3), (4, 3) }
Explanation:
This is because for each x value, the number on the left of the set, there is no other x values of the same number, ( 1, 2, 3, 4)
Hope this helps you with your question!

answer
no change
We've now found that there was (surprisingly) no change in the rectangle's area, despite changing its size.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
A) not true. Sin A = some decimal
Cos 720 = 1
D) That means that d is not true either. not true
B) Sin55 = cos55 is not true either only sin(45) = cos(45) is true. So B is not true.
That leaves C. I think if you check it, you'll find it is right. sin(A) = cos(90 - A)
