Answer:
There are 4 prime numbers from 1 to 10: 2, 3, 5, and 7. This means that there are 4 ways to choose the first outcome. There are 5 composite numbers from 1 to 10: 4, 6, 8, 9, and 10 (1 is just 1). So, you just multiply the two numbers together because each depends on each: 4 * 5 = 20 outcomes.

What out of 9 is 15%?
Y out of 9 is 15%
Equation: Y/X = P%
Solving our equation for Y
Y = P% * X
Y = 15% * 9
Converting percent to decimal:
p = 15%/100 = 0.15
<span>Y = 0.15 * 9 </span>
<span>Y = 1.35

A. The square of an irrational number \sqrt(11)=\sqrt(11)*\sqrt(11)=\sqrt(11^2)=11, which is a rational number. However, in B, C, and D, the two pair of rational numbers cannot multiply to become a rational number.
Answer:
x
Step-by-step explanation:
(2x+8)-(x+8)
Distribute
2x+8-x-8
Combine like terms
2x-x= x
8-8= 0
x
Answer:
Yes, the area of the square would be a rational number.
Step-by-step explanation:
Area of square = 400 units² = x²
x = one side length of square
x = √400 = <u>20 units</u>
Increase each side length by 1 unit.
New side length = <u>21 units</u>
Area of new square = 21² = 441
441 is a rational number because the square root of 400 is a rational number.
√400 = 21
Therefore: If the length of each side of the square increased by one unit, the area of the square would be a rational number. The area of the square would still be a perfect square.
