Triangle FGH is similar to triangle DEF. solve for p
nataly862011 [7]

Answer:

p = 16

Step-by-step explanation:

Given that ∆FGH is similar to ∆DEF, it follows that the ratio of their corresponding side lengths would be equal. Therefore:

\frac{FH}{DF} = \frac{FG}{DE}

FH = 12

DF = p

FG = 24

DE = 32

Plug in the values

\frac{12}{p} = \frac{24}{32}

Cross multiply

12*32 = 24*p

384 = 24p

Divide both sides by 24

\frac{384}{24} = \frac{24p}{24}

16 = p

p = 16

Y varies inversely as x. When x=10, y=20. Find y when x=50
IgorC [24]

Answer:

y=100

Step-by-step explanation:

You can solve this by comparing the ratio.

The first set is 10:20 or 1:2 when simplified.

This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.

1. A college newspaper, The College Spy, has a fixed production cost of $70 per edition and it costs 40¢ per copy to print and d
Mars2501 [29]

a. What is the cost expression for the newspaper? 


The cost would be the sum of fixed cost and the variable cost. The fixed cost is 70 while the variable cost is 0.40 x, where x stands for the number of copies made. That is:

Cost = 70 + 0.40 x            

where x = number of copies made


b. What is the revenue expression for the newspaper? 

The revenue would simply be the product of selling price and number of copies sold or made, that is:

Revenue = 0.50 x


c. Put the cost and revenue expressions into an inequality that would represent a successful newspaper. 


To have a successful newspaper, the difference of revenue and cost must be greater than 0, that is:

Revenue – Cost > 0

0.50 x – (70 + 0.40 x) > 0


d. How many copies should be sold to make a profit? Show all work! An answer with no work will receive 0 points. 

From the above equation, we solve for x.

0.50 x – (70 + 0.40 x) > 0

0.50 x – 70 – 0.40 x > 0

0.10 x > 70

x > 700

Number of copies made should be more than 700 copies


e. Now go back to your answer for d. On every line of your solution write what property of math you would use to justify the transformation that occurred. 

 

0.50 x – (70 + 0.40 x) > 0                Distribution property

0.50 x – 70 – 0.40 x > 0                    Addition property

0.10 x > 70                                           Addition property

x > 700                                                  Division property
