hank orders popcorn while watching a movie. the popcorn was served in a trapezoidal bucket. the height of the bucket is 10x-9 cm
Gnoma [55]

Area of the trapezoidal bucket, A is 130x² - 77x - 36 cm²

Step-by-step explanation:

  • Step 1: Area of a trapezoid = 1/2 (Sum of parallel sides) × Height

Sum of parallel sides = (10x - 2) + (16x + 10)

                                   = 26x + 8 = 2(13x + 4)

Height = 10x - 9

⇒ Area of the bucket = 1/2 × 2(13x + 4) (10x - 9)

                                    = (13x + 4)(10x - 9) cm²

                                    = 130x² - 117x + 40x - 36

                                A = 130x² - 77x - 36

Answer:

Once upon a time, there were a two person family who lived out in the woods. The father took great care of the son. The father was a Botany, but had retired because of his age. But still he loved plants and grew a garden. The garden included Giant Bird of Paradise, Carnations, Irises, and ofc roses. He loved plants so much that he went out to dig a hole and plant different  flowers and plants every spring. When the son grew older he helped the father with the garden. Two years later his son was accused of murder, but the body wasn't found. Next spring came and the father went out to dig. He couldn't Finnish it. He called his son and say he couldn't do the garden thing, because of his age. The son said don't dig there that's where he hid the bodies. The police came to dig the holes and try to find the bodies, but none of them were found. The father called the son again, and the son said thats all I can do for you right now.

You own three different rings. You wear all three rings, but no two of the rings are on the same finger, nor are any of them on
Eddi Din [679]

Answer:

Therefore you can wear your rings in =336 ways

Step-by-step explanation:

Multiplication Law: If one occurs in x ways and second event occurs in y ways.Then the number of ways that two event occur in sequence is xy

Given that you have 3 different rings.

We have total 10 figures.

But you don't wear ring on your thumbs.

We have 2 thumbs.

So you can wear rings on (10-2) = 8 figures.

The ways of wearing of first ring is = 8

The ways of wearing of second ring is = 7

The ways of wearing of third ring is = 6

Therefore you can wear your rings in =(8×7×6)

                                                             =336 ways
