Answer:The Basic Formula

The formula multiplies the area's length in feet by its width in feet and its height in feet. This number is then multiplied by one-third and divided by 27 to convert the answer into cubic yards. To make it clearer, the equation is as follows: (Length (ft) x Width (ft) x Height (ft) x 1/3) / 27.

The side of rhombus is 14 in. The obtuse angle is 160º. Find the longer diagonal of the rhombus.

Mandarinka [93]

Answer:

x = 27.57 in to the nearest hundredth.

Step-by-step explanation:

The longer diagonal is opposite the obtuse angle.

Also as it is a rhombus all sides = 14 in.

Use the Cosine Rule:

x^2 = 14^2 + 14^2 - 2*14^2 cos 160

x^2 = 760.36

x = sqrt 760.36

x = 27.57 in.

Disregarding wind resistance the distance a body falls from rest varies directly as th squares of the time it falls if a skydive

Firdavs [7]

Answer:

The skydiver will fall 1600 ft in 10 seconds.

Step-by-step explanation:

<u>Distance a body falls from rest varies directly as the squares of the time it falls </u>

Let distance = s

time = t

Therefore , s = k $\times t^{2}$

Given, the body falls 64 ft in 2 seconds.

Substituting in above equation,

64 = k $\times (2)^{2}$

64 = k $\times (4)$

k = $\frac{64}{4}$

k = 16 ft/ $s^{2}$

We have to find how much he will fall in 10 seconds.

s = k $\times t^{2}$

s = $16 \times 10^{2}$

s = $16 \times 100$

s = 1600 ft
