If you can buy 1⁄4 pizza for 5 dollars, how much can you purchase for 8 dollars? Write your answer as a fraction.

Answers

This is a problem using proportions.

a/b = c/d where: ad = bc

1/4 : 5 = x : 8

a = 1/4 ; b = 5 ; c = x ; d = 8

get the cross products: ad = bc

1/4 * 8 = 5 * x
8/4 = 5x
2 = 5x
2/5 = x

2/5 of a pizza can be purchased for 8 dollars.

to check:

1/4 : 5 = 2/5 : 8

1/4 * 8 = 5 * 2/5
8/4      = 10/5
  2       = 2
  

Shen is going to rent a truck For one day. There are two companies he can choose from, and they have the following prices.Company a charges $110 and allows unlimited mileage.
Company B has an initial fee of $65 in charges an additional $0.90 for every mile driven.
For what mileages Will company a charge less than Company B

Answers

Answer:

The mileages for which company A charge less than company B when , y > 50 .

Step-by-step explanation:

Given as :

The two truck companies have following prices

Company A

The initial fee = i = $110

And unlimited mileage

Company B

The initial fee = I = $65

Additional charge = $0.90 per mile driven

Let it driven x mile

Let The mileages for which company A charge less than company B = y

Now, According to question

Charges of company A = charges of company B

i.e i = I + 0.90 × x

Or, $110 = $65 + 0.90 × x

Or, $110 - $65 = 0.90 × x

Or, $45 = 0.90 × x

∴    x = (45)/(0.90)

i.e  x = 50

i.e  Company B driven x = 50 miles

So, The mileages for which company A charge less than company B = y

And y > x

i.e y > 50

Hence, The mileages for which company A charge less than company B when , y > 50 . Answer

What is the measure oRCD in the figure below?350

Answers

Answer:

RCD = 35°

Step-by-step explanation:

Analyzing the figure you can observe the following: Both triangles have two equal sides (the CD line and the sides of 11), as well as an equal angle (that of 90°).

When this happens, two equal sides + 1 equal angle it means that the triangles are similar, that is, the measures of their angles are the same.

The angle PCD and RCD are opposite to sides that measure the same (11), so the angle RCD is equal to the angle PCD: 35°

Answer: 35° is the answer
