At a dinner party, two desserts are being served. Six of the guests choose cheesecake, and eight of the guests choose apple pie.

Maslowich

Answer:

When six guests choose cheesecake and eight choose apple pie, the ratio is 6:8. If we use the same prompt but change 6 to 3 and change 8 to 4, the ratio becomes 3:4 with the pie graph looking exactly the same.

6:8 comes out to a total of 14 people

and 3:4 comes out to a total of 7 people

The two ratios are equivalent due to the graphs looking exactly the same as well as that 14 is double of 7.

Matt wants to hire a company to detail his car. Company A charges $15+17h where h represents the hours it takes to detail the ca

tensa zangetsu [6.8K]

Answer:

5 hours

Step-by-step explanation:

First, you set the equations equal, so 20h=17h+15

Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15

Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.

Answer:

39 pi cubic inches

Step-by-step explanation:

The volume of a cone is (1/3)(area of the base)(height).

$V=\frac{1}{3}Bh$

Find the area of the circular base. The circumference of a circle is $C=2\pi r$ , so

$2\pi r = 6\pi\\\\r=3$

Now that you know the radius of the circular base, you can find its area:

$A=\pi r^2 = \pi(3^2)=9\pi$

The height of the cone is 13. Time to use the volume formula.

$V=\frac{1}{3}Bh\\\\V=\frac{1}{3}(9\pi)(13)\\\\V=39\pi$
