A group of students made trees out of paper for a scene in a school play. The trees are shaped like square pyramids. The base is
Readme [11.4K]

Answer:

26.4ft²

Step-by-step explanation:

I first converted the centimeter values to feet

140Cm x 30.48 = 4.59

70cm x 30.48 = 2.3

the paper required is approximately equal to the area of the pyramid.

area of pyramid is equal to area of triangle + base²

Are of triangle = 1/2 x b xh

= 4 x 1/2 x4.59x2.3 + (2.3)²

= 2 x 4.59 x 2.3 + 5.29

= 26.4 feet²

therefore it will take 26.4 feet² paper to make each tree, including the bottom.

a taxi ride costs 40 dollars for the first 500 meters and each additional 300 meters (or a fraction thereof) adds $3.50 to the f
Colt1911 [192]

Answer:

$ 71.5

Step-by-step explanation:

firstly kilometer to meters

<em>1 km = 1000 m </em>

therefore 3 km = 3000m

for the first 500 = $40

hence deduct the 500 from 3000m

3000 - 500 = 2500

now find out how many 300m go into 2500

2500 / 300 = 8.33

which is rounded up to 9

therefore the total amount is :

40 + 9 * 3.5

<u>= $71.5</u>

How do i ask a question in hot questions?
Tcecarenko [31]
Hello!

You can't make one of your questions a "Hot Question"

I Think that the Moderators are the Ones who pick a certain question from certain subjects depending on what they're about.

So yeah, the only thing you can do is post a question and hopefully, leave it in the hands of the Moderators to do the work.

Hope this Helps! :)
