Suppose Aji and sunshine have to pay $11 in royalties for each Beatles song and $7 for each Donovan song. How many of each type

andrey2020 [161]

To minimize their royal costs to $200, the number of Donovan songs to include is <u>15</u> and the number of Beatles songs to include is <u>5</u>.

<h3>What are ratios?</h3>

Ratios are numerical relationships between variables that show how much each variable is contained in another.

Ratios are stated in fractions, percentages, or decimals.

<h3>Data and Calculations:</h3>

Total songs to include in the song = 20

The ratio of Donovan and Beatles = 5:1.5

The number of Donovan songs to include = 15 (20/6.5 x 5)

The number of Beatles songs to include = 5 (20/6.5 x 1.5)

Royalty cost per Donovan song = $11

Royalty cost per Beatles song = $7

Total royalty costs for Donovan and Beatles song = $200 ($11 x 15 + $7 x 5)

Thus, the number of Donovan songs to include is <u>15</u> and the number of Beatles songs to include is <u>5</u>.

<h3>Question Completion:</h3>

Aji and Sunshine want to make a CD of songs from the 1960s to donate to their school library to be broadcast during school picnics. Sunshine's parents were big fans of the 60s singer Donovan, and they named her after his song "Sunshine Superman." Aji's folks were devotees of the Beatles. Aji and Sunshine want their CD to consist entirely of songs by Donovan and the Beatles. Because Sunshine is named after a Donovan song, she wants to include at least as many Donovan songs as Beatles songs. Aji agrees. In return, Sunshine agrees to include at least five Beatles songs. 5 1.5 To provide enough variety to make the mix interesting, they decide to include at least 20 songs altogether.

Use greatest common factor and the distributive property to write equivalent expressions in factored form for the following expr

Nitella [24]

Answer:

a. 4(d+3e)

b. 6(3x+5y)

c. 7(3a+4y)

d. 8(3f+7g)

Step-by-step explanation:

In each case we find the greatest common factor of the numbers. That is the greatest number that goes into both the numbers. Then we factor it out in front and inside parentheses we divide each original term by the greatest common factor:

a. 4d+12e, GCF: 4

$\displaystyle4\left(\frac{4d}{4}+\frac{12e}{4}\right)=4(d+3e)$

b. 18x+30y, GCF: 6

$\displaystyle6\left(\frac{18x}{6}+\frac{30y}{6}\right)=6(3x+5y)$

c. 21a+28y, GCF: 7

$\displaystyle7\left(\frac{21a}{7}+\frac{28y}{7}\right)=7(3a+4y)$

d. 24f+56g, GCF: 8

$\displaystyle8\left(\frac{24f}{8}+\frac{56g}{8}\right)=8(3f+7g)$

The water pressure for a standard fire hydrant is 20 pounds per square inch. Convert this to

Kaylis [27]

<h3>Answer: 2880 pounds per square foot</h3>

==========================================================

Explanation:

psi = pounds per square inch

1 foot = 12 inches

1 square foot = 144 square inches

I squared both sides to get the second equation. Think of a 12 by 12 square representing 12 inches along each side, so that leads to 12*12 = 144 square inches being the same as 1 square foot.

That last equation helps us convert from square inches to square feet like so:

$20 \text{ psi} = \frac{20 \text{ pounds}}{1 \text{ square inch}}\\\\20 \text{ psi} = \frac{20 \text{ pounds}}{1 \text{ square inch}}*\frac{144 \text{ square inches}}{1 \text{ square foot}}\\\\20 \text{ psi} = \frac{20*144}{1*1}*\frac{\text{ pounds}}{\text{ square foot}}\\\\20 \text{ psi} = \frac{2880 \text{ pounds}}{1 \text{ square foot}}\\\\20 \text{ psi} = 2880 \frac{\text{ pounds}}{\text{ square foot}}\\\\20 \text{ psi} = 2880 \text{ pounds per square foot}\\\\$

Notice in the jump from the second step to the third step, we have the "square inches" unit cancel out when dividing. All that's left is "pounds" up top and "square foot" down below.

In short, we simply multiply by 144 to go from 20 to 2880.
