Marcus spent 10 hours doing his homework last week.This week he spent 11 hours doing his homework.He says that he spent 110% mor

KonstantinChe [14]

We know that Marcus spent 10 hours on his homework this week so:
10 hours = 100%

Marcus is saying that he spent 110% more time doing his homework this week, in comparison to last week.

Then to see if he is correct we have to find 110% of 10 hours.

So if: 100% of 10 hours = 10 hours
And: 10% of 10 hours (equivalent to 600 minutes) = 1 hour (or 60 minutes)
Then we add the two: 10 hours + 1 hour
And we get: 11 hours

As a result, Marcus is correct; he did spend 110% more time on his homework this week.

Hope this helps! :D

For what side length(s) is the area of an equilateral triangle equal to 30 cm?? Only enter the number, in centimeters, rounded t

xenn [34]

Answer: The sides length are 8.32 cm

Step-by-step explanation:

An equilateral triangle has all his sides of the same lenght, so we assume that the triangle has an L lenght in his sides.

The area of a triangle is $Area = \frac{base * height}{2}$ where the base is L, the Area is 30 and an unknown height.

To determine the height, we cut the triangle in half and take one side. By simetry, one side has a base of $\frac{L}{2}$ , a hypotenuse of L and a the unknown height.

Then we apply the Pythagoras theorem, this states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides, or, $hypotenuse = \sqrt{c^{2} + c^{2} }$ Where one c is $\frac{L}{2}$ and the other is the height.
