1/2 because 36 is half of 72. You could also divide the numbers by 12 and you will get 3/6 which is the same as 1/2.
In the 7th and 8th grade combined, there 3+5 girls = 8 girls, and 7+5 boys = 12 boys. If there are only boys and girls, then there are 12+8=20 students in all.
The fraction of girls out of the total is P = 8/20 = 2/5.
Actually, the area of the square is 49 cm^2.
The length of one side is sqrt(49 cm^2) = 7 cm (answer)
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:
AB = 3√5
Explanation: You can use
a^2 + b^2 = c^2 formula.
6^2 + b^2 = 9^2.
36 + b^2 = 81.
81 - 36 = 45
√45 = 3√5
