Answer:
9 1/2
Step-by-step explanation:

D = 5/6 sqrt(h)
7 = 5/6 sqrt(h)
42/5 = sqrt(h)
h = (42/5)^2 = 1,764/25 = 70.56
The height of the mast is 70.56 miles
Step-by-step explanation:
In trapezoid ABCF, AB || CF.
Therefore, parallelograms ABEF & ABCD have same height and lie on the same base AB.

From equations (1), (2) & (3), we find:

Thus, the two triangular pieces of land are equal in area.
Hence proved.
Answer: 15 mL
Step-by-step explanation:
Before the stone the reading was 180 mL
When the stone was added the reading rose to 195 mL
So, we subtract them both, this will give us the volume of the stone
195 mL - 180 mL = 15 mL
Answer:
The square root of 49 is 7.
Step-by-step explanation:
To find the square root of 49, you would need to look at the possible multiplication equations. For example:
1 x 49 = 49
7 x 7 = 49
49 x 1 = 49
As you can see, 7 x 7 would have the square root of 49, which is 7.
7^2=49
.
In conclusion, the square root of 49 is 7
