Need Help Dont Know What To Do Im Confused

Answers

Answer 1
the last one is the answer h=2t-d distribute the 1/2 into the (d + h) you get t=1/2d + 1/2 h then multiply everything by the denominator of 2 this would give you 2t = d + h because the denominator of 2 on the d and h cancel out and leaves a 1 infront which is just d and h then i’d u switched the h and 2t across the equation they become the opposite sign -h = -2t + d since you don’t want -h switch all the signs leaving you with the answer h = 2t - d
Answer 2

Answer:

last option;  h = 2t - d

Step-by-step explanation:

t = 1/2(d + h)

t = [tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex]

now multiply each side by 2 to eliminate denominator

2t = 2 ([tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex])

2t = d + h

h = 2t - d

On a map 1 inch = 50 miles. If two cities are 3 1/2 inches apart, how many miles are they apart?

Answers

I think 175 miles.
Since 1 = 50 miles and the cities are 3 1/2 miles apart, all you need to do is multiply 50 x 3 which is 150. Then you need to solve the 1/2, which 1/2 of 50 is 25. 150+25 is 175. So the answer is 175 miles.

The formula for the volume, V, of a cone having the radius, r, and the height, h, is shown below.
V = 3r2h
Write the formula to calculate the height, h.

Answers

Answer:

V/3r²

Step-by-step explanation:

We are to make h the subject of the formula as shown;

V = 3r²h

Divide both sides by 3r²

V/3r² = 3r²h/3r²

V/3r²  = h

Rearrange

h = V/3r²

Hence the formula to calculate the height h is V/3r²

Answer:

h = V/3r²
