Answer:
8
Step-by-step explanation:
The lateral area of a cone is ...
LA = (π/2)ds
where d is the diameter, and s is the slant height.
The area of this tower roof is about ...
LA = (π/2)(12 ft)(13 ft) = 78π ft² ≈ 245 ft²
About 245/32 = 7.7 bundles of shingles will be required for coverage.
You should buy 8 bundles of shingles to cover the roof.
Answer:
A. 30(18a - 6b) and D. 4(10a + 2a - 9b)
Step-by-step explanation:
Answer:
Second number line(from top to bottom).
Step-by-step explanation:
We are given the following inequality:
It is solved similarly to an equality, so:
Multiplying by -1, the signal changes from < to >. So
Thus the correct answer is given by the second number line.
The answer would be m^2+3m+2=0 because the first “part” of the equation (x^2-5) is equal to m; in the equation it’s squared so it can be replaced by m^2. next, 3m is the same as 3(x^2+5) which is what you have when you see 3x^2+15. finally, you have to bring the -2 over from the other side so you have positive 2. hope this helps!
