Answer:
18
Step-by-step explanation:
10% of 30 = 3
50% of 30 = 15
10%+50%=60%
3+15=18
Answer: Any real number x as long as and
In other words, anything but 0 or -2/3 is valid.
========================================================
Explanation:
Set the denominator equal to zero and solve for x
2(3x^2 + 2x) = 0
3x^2 + 2x = 0
x(3x + 2) = 0
x = 0 or 3x+2 = 0 .... zero product property
x = 0 or 3x = -2
x = 0 or x = -2/3
If either x = 0 or x = -2/3, then the denominator 2(3x^2 + 2x) will be zero. But recall that we cannot have zero in the denominator. Dividing by zero is not allowed. The expression is undefined when we divide by zero.
Therefore, we must exclude x = 0 and x = -2/3 from the domain. Any other real number is valid as an x input.
Answer:32,970 and 39250 inches
Step by step explanation:
C=2pi*r
C=2*3.14*11.5
C=72.22
D=C*500
D=72.22*500
D=36,110 inches
This gives you the exact middle so we need to pick the one right above this number and right below this number so
32,970 and 39250 are your answers
Total of $7.75
13 more quarters than nickels
15 nickels = $0.75
28 quarters = $7.00
28 - 15 = 13 coins
$7.00 + $0.75 = $7.75
She has 15 nickels and 28 quarters.
