A radio station requires DJs to play 3 commercials for every 18 songs they play. What is the unit rate of songs to commercials?

Mathematics

6 songs

The way to find this answer is to divide 18 by 3, which is six, which means that after every six songs a commercial is played. 

Hope this was helpful and that I explained it correctly.

" According to the Joy Cone Company, their waffle cones have a diameter of 2 5/8 inches and a
ASHA 777 [7]

Answer:

No, the cone will not hold all of the ice cream.

Step-by-step explanation:

Given:

" According to the Joy Cone Company, their waffle cones have a diameter of 2 5/8 inches and a  height of 6 inches.

If you place one scoops of ice cream (in the shape of a sphere) with a diameter of 2 7/8 inches would let  it melt.

Now, to explain mathematically will the cone hold all of the ice cream.

<u>Taking the value of π = 3.14.</u>

So, to get the volume of waffle cone we put formula:

Height (h) = 6 inches.

Diameter = 2\frac{5}{8}=\frac{21}{8}\ inches.

Thus radius (r) = Diameter ÷ 2 = \frac{\frac{21}{8}}{2} =\frac{21}{16} \ inches.

Volume=\pi r^2\frac{h}{3}

Volume=3.14\times \frac{21}{16} \times \frac{21}{16} \times \frac{6}{3}

Volume=3.14\times 1.31\times 1.31\times 2

Volume=10.78\ inches^3.

The volume of waffle cone = 10.78 inches³.

Now, to get the volume of scoop which is in the shape of sphere we put formula:

Diameter = 2\frac{7}{8} =\frac{23}{8} \ inches.

Thus radius (r) = Diameter ÷ 2 =\frac{\frac{23}{8}}{2} =\frac{23}{16} \ inches.

Volume = \frac{4}{3} \pi r^3

Volume = \frac{4}{3} \times 3.14\times \frac{23}{16} \times \frac{23}{16} \times \frac{23}{16}

Volume=1.33\times 3.14\times 1.44\times 1.44\times 1.44

Volume=12.47\ inches^3.

<em>The volume of one scoop of ice cream = 12.47 inches³.</em>

<u><em>So, as the volume of scoop of ice cream is more than the volume of cone.</em></u>

<u><em>Thus, if placing one scoop of ice cream in the cone and let it melt, the cone will not hold all of the ice cream.</em></u>

Therefore, no the cone will not hold all of the ice cream.

The population of bacteria doubles every 6 hours. By how much will it grow in three days. Write the equation
ch4aika [34]

Answer:

Step-by-step explanation:

let x be the population

so we have ,

2x= 6h

?= 3 days or 3×24h

by cross multiplication we have

2x× 72h= 6h×?

?= 2x×72/6 = 24x

So, in three days the bacteria will b 24 times current population.

Ava deposited $14 in a savings account that earns 2.7% simple interest. What would the graph look like?
katen-ka-za [31]

Deposited amount = $14.

Rate of interest =  2.7%

In decimals 2.7 could be written by dividing 2.7 by 100, we get

0.027.

Interest earned each year = 2.7% of $14 = 0.027*14 = $0.378.

We can make a table to balance by after each year.

First year balance: First year interest + Deposited amount = 0.378 +14 = $14.378.

Second year balance: Second year interest + Deposited amount = 2*0.378 +14 = 0.756+ 14 = $14.756.

Third year balance: Third year interest + Deposited amount = 3*0.378 +14 = 1.134+ 14 = $15.134.

We get four coordinates to graph A(0,14), B(1, 14.378) , C(2, 14.756) and D(3, 15.134).

Plotting those coordinates of the points A, B, C and D on the graph.
