It is 180 - 65
Which is 115 which would be your answer
Answer:
.
It means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
Step-by-step explanation:
Given:
The function relating number of 9 inch tiles required and area to cover is:
Now, plug in 400 for to evaluate .
Therefore, Don required 673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
The answer would be 168 ft tall!
Step by step:
If each floor is 12 ft high, then we can multiply any number by that to get the ft high.
Since there is 14 floors, we can multiply it by 12.
Hope this helped!! :)
Answer:
Step-by-step explanation:
The graph of the absolute value function looks like a V that opens UP and has its vertex at the origin, (0, 0). There are no restrictions on the input, x, so the domain is (-infinity, infinity).
On the other hand, this function has no values less than zero. Its range is
[0, infinity).
5(n - 2) = n + 7
5n - 10 = n + 7
5n - n = 7 + 10
4n = 17
n = 17/4 or 4 1/4 <== ur answer
check..
5(n-2) = n + 7
5(17/4 - 2) = 17/4 + 7
5(17/4 - 8/4) = 17/4 + 28/4
5(9/4) = 45/4
45/4 = 45/4 (correct)
