Leno4ka [110]

Answer:

0.44ft/hr

Step-by-step explanation:

Given parameters:

Quantity of rainfall = 8inches

1ft = 12inches

so;

$\frac{8}{12}$ = 0.67ft

Time = $\frac{3}{2}$ hr

Unknown:

Rate of rainfall expressed in ft/hr = ?

Solution:

The rate of the rainfall is given as;

Rate = $\frac{Quantity}{time}$

Rate = $\frac{0.67ft}{\frac{3}{2} }$ = 0.44ft/hr

The number of windows on each floor form an arithmetic sequence; 124 windows on the first floor, 116 windows on the second floor

zubka84 [21]

Answer:

Formula is 132 - 8n, and there are 52 windows on 10th floor.

Step-by-step explanation:

difference = 116-124 = -8 ( 8 less windows for every floor you go up)

the first fllor has 124 windows

Formula:

$a_{1} = 124$

$a_{n} = 124 + (-8)(n - 1)$ = 132 - 8n

10th Floor:

$a_{10} = 124 + (-8)(10 - 1) = 124 + (-8)(9) = 124 - 72 = 52 windows$

A video camera is being mounted on a bank wall so as to have a good view of the head teller. Find the angle of depression that t

Sever21 [200]

Answer:

The angle of depression of the lens must be 26.3°

Step-by-step explanation:

Here we have a right triangle with the opposite side to the angle equal to 5.93 feet and the adjacent side to the angle equal to 12.02 feet. Therefore we just need to use the tangent definition to find the angle.

$tan(\alpha)=\frac{5.93 ft}{12.02 ft}=0.49$

$\alpha=tan^{-1}(0.49)=26.3^{\circ}$

The angle of depression of the lens must be 26.3°

I hope it helps you!
