Kisachek [45]

Answer: 2/3

Explanation: Assume that the number of smarties he picked is c.

Now, we are given that:

1- He picked 3 times as many cola bottles as smarties. This means that:

Number of cola bottles he picked = 3s

2- He picked twice as many smarties as marshmallows. This means that:

number of marshmallows he picked = 0.5s

Now to get the proportion o f cola bottles, we will divide the number of cola bottles by the total number of sweets as follows:

Please help me with this!

Answer:

___________________________________________________

360 — A

___________________________________________________

Step-by-step explanation:

This is a square based pyramid. Which means that all of the triangles have the same area. All you need to do is find the area of one triangle, multiply it by 4, and add that to the area of the square base.

___________________________________________________

Step 1) FIND THE AREA OF ONE TRIANGLE

Imagine the triangle as a flat 2D shape. The height of this shape would be 13km, that mush is given to us. The length is also given, 10km.

How to find the area of a triangle:

Multiply the height times the width and divide the result by 2.

1. 13 x 10 = 130

2. 130/2 = 65

The area of this triangle is 65km squared.

___________________________________________________

Step 2) MULTIPLY BY 4

65 x 4 = 260

___________________________________________________

Step 3) FIND THE AREA OF THE SQUARE

When you find the area of a square, all you need is the length of one edge. That is 10km in this case.

Multiply this length by itself,

10 x 10 = 100

___________________________________________________

GETTING THE FINAL ANSWER

Add all your results :

260 + 100 = 360
