Answer:
A and B are correct, but A is most correct.
Step-by-step explanation:
just do Pythagorean theorem and see which numbers add up to each other. if you do them for all 4 answers, you see d and c do not equal to each other. b is almost correct, and a comes out exact.
First we need to find the missing side, use

So the missing leg = the sqrt of the hypotenuse squared minus the other leg squared.
Let's substitute the numbers,

Solve for the squares,

Subtract,

Solve for the root,

~~
So our missing length is 8.
To find the perimeter of the triangle, simply add all the sides....

You use the formula a² +b² =c²
so 4² +b² =8²
solve for b
Using weighted average, it is found that she should score 67% on the computer science test.
- The weighted average is given by <u>each proportion multiplied by it's score</u>.
In this problem, the proportions and scores are given by:
- Proportion of 32% = 0.32 for a score of 300.
- Proportion of x for a score of 200.
- Proportion of 46% = 0.46 for a score of 300 + 200 = 500.
Then





She should score 67% on the computer science test.
