Find the tan A and sin B exactly.

Rudik [331]

Answer:

B - tan A = 4/3, sin B = 3/5

Step-by-step explanation:

First, lets find the length of the third side

b = √15² - 12² = √225 - 144 = √81 = 9

Now, lets get Tan A and Sin B

Tan A = 12/9 = 4/3
Sin B = 9/15= 3/5

Correct option is B

On a test Matilda answered 12 out of the first 15 correctly. If this rate continues how many of the next 25 problems will she an

Reil [10]

12/15 = x/100
Multiply 12 x 100 to get 1,200/15 is 80.
Because 25 x 4 = 100, you divide 80 by 4.
Your answer is 20.

what is the volume of a sphere with a radius of "60.5" Ft, Rounded to the nearest tenth of a cubic foot?

Neporo4naja [7]

Answer:

$volume = 927,587.2ft^3$

Step-by-step explanation:

The equation to find the volume of a sphere is as follows:

$volume = \frac{4}{3}\pi r^3$

We have a radius of 60.5ft, let's plug this into the equation and solve:

$volume = \frac{4}{3} \pi (60.5)^3 \\volume = 927,587.17\\volume = 927,587.2$

Therefore, the volume of a sphere with a radius of 60.5ft is 927,587.2ft^3.

Hope this helps!!
