Must do multiplication first....
-2/5 - 3/7 x 7/10
-2/5 - 21/70 (I'll reduce 21/70)
-2/5 - 3/10
Now you have to find a common denominator and subtract
-35/50 = -7/10......is what I get

The distance between the flagpole and the building is the number of feet between them

The building is 162 feet from the flagpole

<h3>How to determine the distance</h3>

The given parameters are:

  • Flagpole = 40 feet
  • Building Shadow = 324 feet

The flagpole's shadow is 50% longer than the flagpole.

So, the length (l) of the flagpole's shadow is:

l = 40 * (1 + 50\%)

l = 60

The length of the building's shadow (d) is then calculated as:

60 : 40 =d :  324

Express as fraction

\frac{60}{40}= \frac{d}{324}

1.50 = \frac{d}{324}

Solve for d

d = 1.50 * 324

d = 486

The distance (x) of the building from the flagpole is then calculated as:

x = 486 - 324

x = 162

Hence, the building is 162 feet from the flagpole

A restaurant bill comes to $28.35. Determine the total cost if the tax is 6.25% and a 20% tip is left on the amount before tax
Soloha48 [4]
In the given problem there are several known and important facts to take note of. Firstly the restaurant bill without tax and tips is $28.35. Then the tax of 6.25% needs to be added with the bill. Also a tip of 20% on the original bill needs to be added to find the total cost.
Then tax on the restaurant bill = (6.25/100) * 28.35
                                                 = 1.77
So the tax on the restaurant bill is $1.77
Amount of tips given = 28.35 * (20/100)
                                 = 5.67
Amount of tips paid is $5.67
Total cost paid in the restaurant = ( 28.35 + 1.77 + 5.67) dollars
                                                   = 35.79 dollars
