Minchanka [31]3 years ago
3 0

Answer:

Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\

Step-by-step explanation:

We have a 4-sided triangular pyramid , where

Q=\frac{\pi}{2}*H\\P=Q*\sqrt{\frac{1}{2}+\frac{4}{\pi ^{2}}}\\Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\

What scale factor was used in going from the grey triangle to the yellow triangle?
Lena [83]

Answer:

2

Step-by-step explanation:

First, we need to find out the length of the third side of the triangle. (The right side of the Y-axis) We use the pythagorean theorem to find it. 4²+2² = 20 find the square root of 20 √20 = ~4.5 so with this in mind, lets find the length of the whole triangle. 8²+4²=80 then √80 = ~9 with this, we can say that since the length of one of the legs has increased by 2, and so has the length of the base, and also the length of the hypotenuse, the scale factor must be 2.

three boards are placed end to end to make a walkway. the first board is 4 feet 5 inches long, the second is 6 feet 9 inches lin
AysviL [449]

Answer:

15 feet 1 inch

Step-by-step explanation:

Given :

Length of boards placed end to end :

Board 1 = 4 feet 5 inches

Board 2 = 6 feets 9 inches

Board 3 = 3 feets 11 inches

The length is the addition of the lengths of the 3 boards :

4 ft 5in + 6 ft 9 in + 3 ft 11 in

(4+6+3) ft + (5+9+11) in

13ft + (25in)

1 ft = 12 in

25 in = 2 ft 1 in

13 ft + 2ft 1 in

15 ft 1 in
