Answer: Part a) 375 pounds, Part b) 8 words

Step-by-step explanation:

Since n represents the number of words there are, we can plug in 20 for n into the equation to get:

C = 15*20 + 75 pounds

C = 300 + 75 pounds

C = 375 pounds

Since C represents the cost of the advert, we can plug in 195 for C into the equation to get:

195 = 15n + 75

Subtract 75 from both sides:

120 = 15n

Divide both sides by 15:

n = 8 words

Answer:

146%

Step-by-step explanation:

To find the percent increase/decrease:

1. Subtract the original value from the new value.

2. Divide by the original value.

3. Multiply the decimal by 100 to convert to a percent.

98.9 - 40.2 = 58.7

58.7/40.2 = 1.46

1.46*100 = 146%

A parcel delivery service will deliver a package only if the length plus girth (distance around) does not exceed 84 inches. (A

Kisachek [45]

Answer:

A. 14x14x28

B. The maximum volume is 5488 cuibic inches

Step-by-step explanation:

The problem states that the box has square ends, so you can express volume with:

$v=x^{2} y$

Using the restriction stated in the problem to get another equation you can substitute in the one above:

$4x+y=84\\\\$

Substituting y whit this equation gives:

$v=x^{2} (84-4x)\\\\v=84x^{2} -4x^{3}$

Now find the limit of x:

$\frac{84x^{2}-4x^{3}}{dx}=168x-12x^{2}\\\\x=\frac{168}{12}=14$

Find the length:

$y=84-4(14)=28$

You can now calculate the maximum volume:

$v=(14)^{2}(28)= 5488$

RoseWind [281]

Answer:

2A/b

Step-by-step explanation:

A=1/2(b)(h)

2A=(b)(h) Multiply both sides by 2

2A/b=h Divide both sides by b

h=2A/b
