Hello! I would love to help! :)

Number 4:

First, let’s find 45% of $37, because we need to see how much to mark up the ball. We can do this by multiplying 45% (0.45) by 37

0.45*37= 16.65

Now, add that number to the original price of the ball to find the retail price.

16.65+37=53.65

So, $53.65 is the answer for number four!

Number 5:

Since you know that the area the sprinkler is spraying is a circle, we can use the formula for areas of circles. That formula is
A=πr^2

Since we know the radius is 8 ft. (I think... the pic cuts it off a little), we can plug that in for r

A=π8^2

You will get
201.0619298297468


Now, round it down to the nearest 100th

201.06

So, 201.06 square feet is your answer for five.


Hope this helps! Comment if you have any questions!

If I have a line that starts at the origin (0,0), and goes 13 meters at an angle of π/6 in the standard position (ie. 30° north
Klio2033 [76]

Line goes 11.2583303 meters in the x direction (east) and 7.5 meters in the y direction (north) .

<u>Step-by-step explanation:</u>

Here we have , If I have a line that starts at the origin (0,0), and goes 13 meters at an angle of π/6 in the standard position (i.e. 30° north of east) . We need yo find how far does it go in the y direction (north), and how far does it go in the x direction (east). Let's find out:

According to question we have a right angle triangle as :

Hypotenuse =13m\\x=\frac{\pi}{6} =30

x direction (east)

We know that ,

⇒ cosx = \frac{Base}{Hypotenuse}

⇒ cos30 = \frac{Base}{13}

⇒ \frac{\sqrt{3} }{2} = \frac{Base}{13}

⇒ Base=\frac{\sqrt{3}(13) }{2} m

⇒ Base=11.2583303m

y direction (North )

We know that ,

⇒ sinx = \frac{Perpendicular}{Hypotenuse}

⇒ sin30 = \frac{Perpendicular}{13}

⇒ \frac{1}{2} = \frac{Perpendicular}{13}

⇒ Perpendicular=7.5m

Therefore , Line goes 11.2583303 meters in the x direction (east) and 7.5 meters in the y direction (north) .

Advance says you can double your money in 10 years if you put $1,000 and a simple interest account What annual interest rate doe
lesya692 [45]
Ok
I=PRT
P=present amount
I=interst
T=time in years
R=rate in percent


when you double your money, interest=present amount
I=1000=P
T=10 years
so
1000=1000(10)(R)
1000=10000R
divide both sides by 10000
0.10=R
10% is answer
