The diagram shows a circle inside a square.<br> a O<br> 16 cm<br> Work out the area of the circle.
LuckyWell [14K]

Answer:

perimeter of circle=2πr

16=2πr

r=16/2π=8/πcm

now.

area of circle=πr²=π(8/π)²=π×64/π²=64/(22/7)=64×7/22=20.36cm²

Abe real estate is developing 15 solar homes per states. If the cost of each home is estimated at 80,000 what’s the projected co
Soloha48 [4]

Answer:

the Total cost= 1,200,000*number of states

Step-by-step explanation:

Given the  cost of each home is $80,000

The number of homes per state are 15

The Total cost of the project is = (Total number of houses per state) * (cost of each house) * (the number of states).

Therefore the total cost =15*80000*Number of states.=1,200,000*number of states

The equation tan(55) = 15/b can be used to find the length of line AC.what is the length of line AC round to the nearest 10th 3.
Nadusha1986 [10]

Answer:

10.5 in

Step-by-step explanation:

Given

tan(55) = \frac{15}{b}

Required

Find length AC

The question is not detailed enough; so, I'll assume that b represents line AC.

Having said that;

We start by multiplying both sides by b

tan(55) = \frac{15}{b}

b * tan(55) = \frac{15}{b} * b

b * tan(55) =15

Divide both sides by tan(55)

\frac{b * tan(55)}{tan(55)} = \frac{15}{tan(55)}

b = \frac{15}{tan(55)}

Find tan(55)

b = \frac{15}{1.42814800674}

b = 10.5031130731

b = 10.5  <em>(Approximated)</em>

<em />

Length AC is 10.5

A cat chases a mouse. The cat is originally 4 feet behind the mouse, which is running in the same direction along the same route
Darya [45]

The cat will take 0.8 seconds  to catch up with the mouse

Step-by-step explanation:

Given:

The  distance between the cat and the mouse =  4 feet

cat's speed  = 17 feet per second.

mouse's speed =  12 feet per second

To Find:

how long will it take the cat to catch up with the mouse = ?

Solution:

We know that

distance  = speed x  time

Rewriting the equation for time we get

time  =\frac{distance }{speed}

now we know that distance is  4 feet

and the speed is 17 -12 = 5 feet per second

Thus the time is

= \frac{4}{5}

= 0.8 seconds
