Three angles of a hexagon are congruent. The other three angles are also congruent, each with a measure twice that of the first

three. What is the measure of each angle?

Serga [27]3 years ago

The sum of the interior angles of a hexagon is 720 degrees. If 3 angles are congruent, each with measure x degrees, and the other 3 angles are also congruent to each other, each with measure 2x degrees, then the total sum of all 6 angles would be 3x + 3(2x) = 9x. If this is equal to 720, then x = 80 degrees, while 2x = 160 degrees.
Therefore, there are 3 80-degree angles and 3 160-degree angles.

You can peel 48 potatoes in 10 minutes. How long will it take you to peel 100 potatoes?
dybincka [34]

Answer:

About 20.8 minutes

Step-by-step explanation:

TO solve this just think of it as a ratio. The number of potatoes goes on top and the time goes on bottom.

48

__

10

That is what the first one would look like. In the second one we know the number of potatoes but we are trying to find the time (x).

100

___

 x

Take these two ratios and set them equal to each other.

\frac{48}{10} =\frac{100}{x}      Next you cross multiply (take 48 times x and 100 times 10).

48x=1000    Now divide by 48 and you have your answer.

About 20.8 minutes

A teenager’s heart pumps an average of 7200 L of blood every 24 hours. What is the rate of change of volume of blood?
love history [14]

Answer:

300L per hour

Step-by-step explanation:

The rate of change of volume of blood pumped by the teenager's heart expresses the volume of blood pumped with respect to hour.

Rate of change of volume of blood = \frac{volume of blood}{time}

                           = \frac{7200L}{24}

                           = 300L/hour

The rate of change of volume of blood by the teenager's heart is 300 litres per hour. This implies that his/ her heart pumps 300 litres of blood every hour.
