Answer:
26 meters
Step-by-step explanation:
a = bh
416 = 16h
Divide both sides by 16
h = 26
26 meters
1/3 of 45 is 15, meaning 15 students gave their speech on day 1
Today 2/5 of the remaining students gave their speech. That’s 12 more
So a total of 27 students gave their speeches. That means 18 students remain. The answer is 18
Here's how to do dividing in a certain ratio:
-- You want to divide up the whole thing in the ratio of
4 parts, 5 parts, and 9 parts.
-- How many parts all together ? (4 + 5 + 9) = 18 parts all together.
-- The whole thing is 180, and that's 18 total parts.
So each part is (180/18) = 10 degrees.
4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.
Check: (40 + 50 + 90) = 180 . yay!

For the second one, I think there are some words missing.
Here we multiply the 2nd eqation with -1 and then add both
and answer is
-6y=12
Answer:
the area would be 4 times
Step-by-step explanation:
4* 17 = 68
8* 34 = 272
272/68= 4
