Answer:
<u>its 11</u>
Step-by-step explanation:

Answer:
5w^2 + 6w - 32
Step-by-step explanation:
Subtract as needed and combine like terms
(-2w^2 + 6w - 19) - (-7w^2 +13) dont forget to distribute the negative
so you get this:
-2w^2 + 7w^2 = 5w^2
6w
-19 - 13 = - 32
your answer is 5w^2 + 6w - 32
hope this helps :)
Answer: 42/11 = 21/5.5
Step-by-step explanation:
1) Since the hypotenuse is 42 for one of the triangles it must be similar to the other triangles hypotenuse, 11.
2) Therefore, the ratio is 42/11.
3)The adjacent sides to the right angle are 21 and 5.5.
4)Therefore, the ratio is 21/5.5
Answer:
the class has 12 girls and 16 boys what is the ratio of the total students to boys in simplest form
The area tom the right of the z-score of 2.75 under a statistical normal distribution curve will be given by:
1-P(z≤2.75)
but
P(z≤2.75)=0.997
thus
1-P(z≤2.75)
=1-0.997
=0.003
Answer: 0.003
