The radius is 5.5 feet.
The area of the whole circle is A = (5.5) squared pi.
The area of the whole circle is A = (11) squared pi.
The area of the shaded region can be found by multiplying the area of the whole circle by three-fourths as in A = three-fourths (pi times r squared).
The area of the shaded region can be found by multiplying the area of the whole circle by two-thirds as in A = two-thirds (pi times r squared).

David is running a 500 m sprint. so far he has run 300 m. what fraction of the spirit does he have left?
?
__
?
what percent?________%

Answers

40 percent is left to run

Answer:

200/500=2/5

40%

Step-by-step explanation:

If the total distance of the sprint is 500m and he's already run 300m, so subtract 500-300 which equals 200.

Then put it in fraction form 500 being the total distance needing to be traveled in all will be your denominator and 200 being the distance left to be traveled will be your numerator. 200/500

Then simplify=200/500 divided by 100/100 equals 2/5.

Then to get it to a percentage divide 2 by 5 which equals  .40

Then convert to a percentage 40%

A cake recipe requires flour and sugar in a ratio of 4 to 3. Which table has been generated using this ratio?

Answers

I think the third one because they are all multiples of 3

Answer:

The third table

Step-by-step explanation:

A ratio is a relationship that illustrates how many times one number contains another. For example, the ratio of 4:3 means there is 4 cups of flour for every 3 cups of sugar. The third table is the only one that increases proportionate to the ratio. This can be seen because when 4 is multiplied by 3 to get 12, so is 3 to get 9. This pattern continues, with both amounts being multiplied by the same number.
