Answer:In order to calculate the volume of a composite figure, first you separate the two figures.Then, find the volume for each figure by multiplication.Lastly, add the volumes of the two shapes.
Step-by-step explanation I checked by the sample response.

Three equivalent ratios:
16:20
24:30
32:40
Answer:
2/10
Step-by-step explanation:
If you are trying to find out the probability of a number just know that the whole number is always going to be the denominator. In this problem, the denominator is <em>10</em> because that is the whole number of pieces of paper.
Then we look at the second part of the problem where it is asking us to figure out the probability of pulling out a number that is less than 3 which would only leave us with <em>1-2 </em>
This means that the probabilaty of pulling out a number less than 3 is <u><em>2/10</em></u>
The surface area of the two triangles is 12 cm^2.
3*4=12
The surface area of the bottom rectangle is 8 cm^2.
4*2=8
The surface area of the rectangle that is on the left side of the figure is 6 cm^2.
3*2=6
The surface area of the rectangle that is on the top side of the figure is 10 cm^2.
To find the third side of the triangle, use the Pythagorean theorem.
3^2+4^2=h^2
9+16=25
The third side of the triangle is 5 cm.
The surface area of the whole figure is 36 cm^2.
12+8+6+10=36
