Determine whether the given lengths can be sides of a right triangle. Which of the following are true statements. A.The lengths
Stels [109]

Answer:

Given sides 12, 16 and 20 can be the sides of right triangle.

Step-by-step explanation:

Sides of right triangle always follow the Pythagoras theorem.

i.e (base)^2 + (Height)^2 = (Hypotenuse)^2

For the given Lengths 7, 40 and 41

We need to check if

7^2 + 40^2 =41^2 \\or\\ 7^2 + 40^2 \neq41^2

Since \\7^2 + 40^2 = 1649\\and \\41^2 = 1681

That means, \\ 7^2 + 40^2 \neq 41^2

hence 7,40 and 41 can not be the sides of right triangle.

Next,

Given sides 12,16 and 20.

Again follow the similar process used in the above problem.

12^2 + 16^2 =400\\And \\20^2 = 400\\Since 12^2 + 16^2 = 20^2

Therefore given sides 12,16 and 20 can be the sides of right triangle.

How to find the volume of this composite figure
babymother [125]
1st you're going to want to divide the figures into smaller parts. I deviated them and got the measurements 2W, 1L, and 2H. The formula for rectangular prisms is LxWxH and I got 4.

Now we need to use the same formula for the other figure. 
4L, 2W, and 1H.  
Multiple them all and we get 8

Now we take the Volume of both the figures and add them together 8+4 = 12
So, the volume of the composite figure is 12

Bogdan [553]

Answer: Jamar is correct

Step-by-step explanation:

Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.

A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.

From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.
