A balloon is rising vertically at the rate of 12 feet per second; at the same time, it is being blown horizontally by a wind of

Nuetrik [128]

Answer:

Angle is 33.82°

Step-by-step explanation:

It is given that, from the figure below,

Vertical distance = 12 feet

Horizontal distance = 18 feet.

Using the trigonometric rule for the right triangles, we have,

$\tan x=\frac{perpendicular}{base}$

i.e. $\tan x=\frac{12}{18}$

i.e. $\tan x=0.67$

i.e. $x=\arctan 0.67$

i.e. x= 33.82°

Thus, the angle made by the path with the horizontal is 33.82°.

Please find the volume of the cone!!

daser333 [38]

$volume = \frac{1}{3} \times \pi \times {r}^{2} \times h$

Plugging in our values,

$volume = \frac{1}{3} \times 3.142 \times {1}^{2} \times 2 = \frac{1}{3} \times 3.142 \times 2 = 2.095{m}^{3} \\$

So the answer is,

$2.095{m}^{3}$

2.75

step-by-step explanation:

5 and 3/8 inches = 5 + 3/8 = 5 + 0.625 = 5.625

2 and 7/8 inches = 2 + 7/8 = 2 + 0.875 = 2.875

the inches that snow melted: 5.625 - 2.875 = 2.750
