A and B
Step-by-step explanation:
I tried it and it was correct. The United states has the tallest... and China has more buildings... are the correct ones.
<span> The product of two perfect squares is a perfect square.
Proof of Existence:
Suppose a = 2^2 , b = 3^2 [ We have to show that the product of a and b is a perfect square.] then
c^2 = (a^2) (b^2)
= (2^2) (3^2)
= (4)9
= 36
and 36 is a perfect square of 6. This is to be shown and this completes the proof</span>
Answer:
Hope this helps! If I could have brainliest I'm trying to rank up.
Step-by-step explanation:
First find the probability of each color being drawn.
We need to find the total number of marbles first.
4 + 3 + 6 = 13
Everything will be over 13.
Probability of a white marble being drawn --> 4/13
Probability of a blue marble being drawn --> 3/13
Probability of a red marble being drawn --> 6/13
Now to find the probabilities of more than one being drawn, we can multiply.
Part A:
6/13*6/13=36/169
Part B:
3/13*3/13=9/169
Part C:
6/13*6/13=18/169
Part D:
7/13*7/13=49/169
To be able to solve this question, we need to know about the Pythagorean theorem: a² + b² = c². A and b represents the two sides that make the right angle, and C represents the hypotenuse, or the longest side, of the triangle.
We know that the hypotenuse is the longest side of the triangle, so that means 9 is c. One side of the triangle is 6, and we have to solve for b. That means 6 is a. We can plug in our values to the formula like this:
Now that we have our equation down, we know what we have to do next: subtract 81 from 36 to get b².
