.35 x .7

.245

35 times 7 is 245

Because there are three letters to the right of the decimal, the decimal then goes three places to the left.

Answer:

87.7 degrees.

Step-by-step explanation:

In triangle ABC, attached.

The height of the building |AB|=443 meters

The distance of the agent across the street , |BC|=18 meters

We want to determine the angle at C.

Now,

$Tan C=\dfrac{|AB|}{|BC|} \\C=arctan (\dfrac{|AB|}{|BC|} )\\=arctan (\dfrac{443}{18} )\\=87.67^\circ\\\approx 87.7^\circ $(correct to the nearest tenth)$

The agent should sfoot his laser gun at an angle of 87.7 degrees.

Answer:

1. 3sqrt(2)

Choice C

2. 2sqrt(3)

Choice D

Step-by-step explanation:

1. sqrt(x+3)

sqrt(15+3)

sqrt(18)

sqrt(9*2)

sqrt(9)sqrt(2)

3sqrt(2)

Choice C

2. 6/sqrt(x)

6/sqrt(3)

no radicals in the denominator, multiply by 1 in the form of the radical

6/sqrt(3) * sqrt(3)/sqrt(3)

6sqrt(3)/ (sqrt(3)*sqrt(3))

6sqrt(3)/3

2sqrt(3)

Surface area of cylinder

steposvetlana [31]

Answer:

The answer is C. $256\pi$ $in^2$ .

Step-by-step explanation:

To solve for the surface area of this cylinder, start by using the cylinder surface area formula, which is $SA=2\pi rh+2\pi r^{2}$ . Next, plug in the information given from the problem into the formula, which will look like $SA=(2)(\pi )(8in)(8in)+(2)(\pi )(8in^{2})$ . Then, simplify the equation, which will look like $SA=(128in)(\pi) +(128in)(\pi)$ . The next step is to simplify the equation further, which will look like $SA= 256\pi$ $in^{2}$ . The final answer is $256 \pi$ $in^2$ .
