Answer:

640.5 cm^2

Step-by-step explanation:

So the formula for trapezoid is height times the average of the bases. So 25+36=61, and then we divide that by 2 to get 30.5 as our average. Then, we take 30.5 and multiply it by 21 and we get 640.5.

A pair of pants with a marked price of $35.00 has a discount of 20%. How much is the discount? Can someone help me learn to do p
andreyandreev [35.5K]
When you see a "%" you need to ask " a percent of what"?

Here, it's a percent of the original prize, so the discount is 20% of the original prize, that is 20% of 35.

20% is also 20/100 or 1/5, so we can calculate this like this:

\frac{1}{5} *35=7

so the discount is 7 dollars.

9 games

You can get this by multiplying each percentage by the total number of games to see what they have to expect.

.55*180 = 99 games (red team)

.60*180 = 108 games (blue team)

Now subtract the blue team expectation from the red team.

108 - 99 = 9 games.

Mimi needs eleven 18-inch pieces of rhinestone ribbonShe purchased 5 yards of the ribbon shown at the rightWhat is the total amo
GalinKa [24]

Answer:

5.5 yards.

Step-by-step explanation:

We have been given that Mimi needs eleven 18-inch pieces of rhinestone ribbon. She purchased 5 yards of the ribbon. We are asked to find the total amount of ribbon that Mimi needs.

First of all, we will multiply 11 by 18 to find amount of ribbon needed in inches as:

\text{Amount of total ribbon in inches}=11\times 18\text{ inches}

\text{Amount of total ribbon in inches}=198\text{ inches}

We know that 1 yard equal to 36 inches. To convert 198 inches into yards, we will divide 198 by 36 as:

\text{Amount of total ribbon in yards}=198\text{ inches}\times \frac{1\text{ Yard}}{\text{36 inches}}

\text{Amount of total ribbon in yards}=\frac{1\text{19 Yard}}{36}

\text{Amount of total ribbon in yards}=5.5\text{ Yards}

Therefore, the total amount of ribbon that Mimi needs is 5.5 yards.
