Answer:

The number of feet away from the sprinkler where it could spread water would be the radius of the circle in which it is spraying.

The Area of a circle is

πr2=808.64

(3.14)r2=808.64

Divide both sides by 3.14

r2=257.5286624

Answer:

40 miles because they are da same size

Step-by-step explanation:

The perimeter of lot C is 46.64 miles

Lot C is a square, hence the perimeter of lot C with a length of each side as a miles is:

Perimeter = 4 * length = 4a

40 = 4a

a = 10 miles

Lot B is a square, hence the perimeter of lot B with a length of each side as b miles is:

Perimeter = 4 * length = 4b

24 = 4b

b = 6 miles

Let c represent the length of lot A,, since a, b, c form a right angle triangle. Using Pythagoras theorem:

c² = a² + b²

c² = 10² + 6²

c² = 136

c = 11.66 miles

Perimeter of lot C = 4 * c = 4 * 11.66 = 46.64 miles

The perimeter of lot C is 46.64 miles

Answer:

m<5 = 133°

m<8 = 47°

Step-by-step explanation:

if <2 = 47°, and <5 is supplementary to <2, that means that together they both have to equal 180°. So, to get the measure of <5, you need to do 180 - 47 to get <5 = 133°.

Now, <5 (133°) is supplementary to <8, so they both have to equal 180° together. So, you must do 180 - 133 to get <8 = 47°. Or, another way to get <8 is to notice that <2 and <8 are alternate interior angles, which means they equal the same amount. So if <2 = 47°, then so does <8.

The interest earned on a $30,000 deposit for six months at 1.5% interest compounded continuously will be $225.846.

Compound interest is applicable when there will be a change in the principle amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.

The continuously compound interest formula is given by

P = P₀[tex]e^{rt}[/tex] where r is the annual interest rate and t is the time period in years.

So,

P₀ = 30000

r = 1.5% = 0.015

t = 6 months = 0.5 year

So,

P = 30000[tex]e^{0.015(0.5)}[/tex]

P = 30000 × 1.007528195

P = $30225.84586

So, interest

I = 30225.84586 - 30000 = $225.8486

Hence " The interest earned on a $30,000 deposit for six months at 1.5% interest compounded continuously will be $225.846".

The surface area of the rectangular prism is 164 square in.

Important information:

The surface area of a rectangular prism is:

[tex]A=2(lb+bh+hl)[/tex]

Where, [tex]l,b,h[/tex] are the dimensions.

Using the above formula, we get

[tex]A=2(4\cdot 10+10\cdot 3+3\cdot 4)[/tex]

[tex]A=2(40+30+12)[/tex]

[tex]A=2(82)[/tex]

[tex]A=164[/tex]

Therefore, the surface area of the rectangular prism is 164 square in.
