<span>We can use the Pythagorean theorem to solve for the diagonal (hypotenuse) length of the gate. This theorem states that a^2 + b^2 = c^2 where a and b are the leg lengths and c is the hypotenuse length. In this case, 80^2 + 60^2 = 6400 + 3600 = 10,000 = c^2. Taking the square root, we see that the length of the brace is 100 inches (thus making the gate a standard 3-4-5 right triangle).</span>

Answer:

x= 12

Step-by-step explanation

3x+8=44

then divide by 3 on both sides

3x=36

3    3

which leaves : x=12

Answer:

Jack is incorrect because a triangle's interior angles should add up to 180°.

You want to put a 4 inch thick layer of topsoil for a new 28 ft by 14 ft garden. The dirt store sells by the cubic yards. How ma
Digiron [165]

Answer:

Step-by-step explanation:

1 yard = 3 feet = 36 in

so 1 in = 1/36 yard,  1 ft = 1/3 yard.

The volume of the layer of the topsoil, is:

4 in * 28 ft * 14 ft = 4 *(1/36)*23*(1/3)*17*(1/3)  yard cubed =

(4*28*14)/(36*3*3)= 1955/324=

The store only sells increments of 1/4 = 0.25 cubic yards.

we need 6.034/0.25=

So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
