Shanell answered al of her answer on her science test she had 90% correct there were 40 questions how many did she get incorrect

4

Step-by-step explanation:

If she got a 90% on her test, and the test was 40 questions long, we need to do a bit of division and multiplication.

We have to divide 40 by 100, as percentages are out of 100.

So now we have 0.4.

Now we multiply this by 90.

36. She got 36 answers correct out of 40, which means she got four wrong.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
