Answer:
9
Step-by-step explanation:
12-5=7 so...
2+7 = 9
y = 9
speed equals 825 divided by 17
speed equals to 48.5miles per hour
gas mileage equals to 825/38
gas mileage equals to 21.7
125/38 equals to 3.3 unit price
Answer: The second term of the expression which is 0.25x is the variable cost which is the extra amount paid for being late.
The expression 2 + 0.25x represents the amount that Ruth paid for the book.
It should be noted that the fixed cost is represented by 2 while the 0.25 represents the variable cost which is the late fee. Also, the x represented the number of days for being late.
In conclusion, the second term of the expression represents the amount that was charged for being late.
Answer:
4.5×10^17 m²
Step-by-step explanation:
The radius is half the diameter, so we can make the substitution r=d/2 into the formula to get ...
A = 4πr² = 4π(d/2)² = πd²
Filling in the given values and doing the arithmetic gives ...
A = 3.14×(3.8×10^8 m)² = 45.3416×10^16 m²
A ≈ 4.5×10^17 m²
__
We round to 2 significant digits because that is the precision of the given diameter.
Answer:
w = x = 36
Step-by-step explanation:
In the largest triangle, the longest side is x
The shortest side = 18
In the smaller triangle the longest side is 6
The shortest side is 3
You can set up a ratio
x/18 = 6/3 Divide the right side by 3
x/18 = 2 Multiply both sides by 18
18 *x / 18 = 2 * 18
x = 36
