A right triangle. If AC = 7 and BC = 8, find AB. Leave your answer in simplest radical form.
harkovskaia [24]

We don't know whether those two sides are both legs
of the right triangle, or if  BC  is the hypotenuse.

If  AC  and  BC  are both legs, then

           AB = √ (AC² + BC²)
                 =  √ (7² + 8²)
                 =  √ (49 + 64)  =  √ 113 .

If  BC  is the hypotenuse of the right triangle, then

           AB = √ (BC² - AC²)
                 =  √ (8² - 7²)
                 =  √ (64 - 49)  =  √ 15 .

Tony paid 35% of the bill. Eric paid 3/8 of the bill. Jeff paid .175 of the bill and Gary paid 1/10 of the bill. Place the peopl
Blizzard [7]

Answer:

Eric,Tony,Jeff,Gary

Step-by-step explanation:

Given the payments made by each individual below:

  • Tony paid 35% of the bill.
  • Eric paid 3/8 of the bill.
  • Jeff paid 0.175 of the bill
  • Gary paid 1/10 of the bill.

The most convenient way to order their payments is to convert each to percentage.

Eric paid 3/8 of the bill.

  • In Percentage: \frac{3}{8}X100=37.5\%

Jeff paid 0.175 of the bill

  • In percentage, 0.175 X100 =17.5%

Gary paid 1/10 of the bill.

In Percentage: \frac{1}{10}X100=10\%

Therefore, the order from most to least is:

Eric(37.5%), Tony(35%),Jeff(17.5%),Gary(10%)
