Answer:
27
Step-by-step explanation:
If the ratio is 1:3 multiply that by 9:9 so you effectively get 9:9x3 = 9:27. Or, you can say to yourself if B (3) is 3 times greater than A (1) then B is 3 times greater than 9. So 9x3 = 27
I'm may not be that good at math, but I'm going to try my best to help you, because I know how it feels to be in this situation!
The first one :
You might be right on D. But I'm thinking B also. The question asks "Which could be a cross section of a rectangular pyramid that has been intersected by a plane perpendicular". But a triangle is basically a flat pyramid.
(I'm typing really fast to help!!!!)
Second one: Its B!! Look at it really closely! You'll get it!!!
(Going really fast now!!!!)
Third one: Between B or D!!! But I think you're right on your choice!!!!
(FASTER FASTER!!!)
FINALLY: Copy and paste your answers into google. People have asked the same question!
I hope I helped. I don't want to make you fail, as I am in the SAME similar situation as you! I really REALLY REALLY HOPE YOU PASS!!!
Answer:
false
Step-by-step explanation:
Answer:
let anumber be x so
2*x=2x
Step-by-step explanation:
Answer:
x ≈ 73.3
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos39° = 
= 
( multiply both sides by x )
x × cos39° = 57 ( divide both sides by cos39° )
x = 
≈ 73.3 ( to the nearest tenth )
