if fred can blow up 20 balloons up in 15 minutes then how many balloons can fred blow up in 6 minutes ​

8

Step-by-step explanation:

have a good day

The Answer is 8

Step-by-step explanation:

Hello,

The answer to the question is 8, let me explain why.

1. we know how many balloons Fred can blow up in 15 minutes

Fred can blow up 20 balloons in 15 minutes.

2. we need to find out how many balloons Fred can blow up in 1 minute.

To solve this we just divide 20 by 15

20 ÷ 15 = 1.3 (repeated)

3. Finally we multiply the answer by 6

This will give us the answer of 8

because 1.3 × 6 = 8

Hope I could help, Hope it was easy to understand as well.

The area of a trapezoid is basically the average width times the altitude, or as a formula:
Area=h·

b1+b2
2

where
b1, b2 are the lengths of each base
h is the altitude (height)
Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases.

In the applet above, click on "freeze dimensions". As you drag any vertex, you will see that the trapezoid redraws itself keeping the height and bases constant. Notice how the area does not change in the displayed formula. The area depends only on the height and base lengths, so as you can see, there are many trapezoids with a given set of dimensions which all have the same area.
