The answer is 10.
Here's why:
The equation that we have is y=3x+4 , we know the value of x , but not the value of y.
If x=2 , the new equation is:
y=3(2) + 4
3(2)= 6 + 4=10
The answer is 10 which means that B is correct.

PLZ help Asap!!!!!!!!!!!!!!!!!!!!!!!

maria [59]

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!!!

At a speed of 22 revolutions per minute, how long will it take a wheel of radius 10,

Bogdan [553]

Well, if the radius is 10, then the circumference is $\frac{2*10*22}7=\frac{440}7$
What's the unit? Either way, 22 rev. per minute means each minute you go by $22*\frac{440}7=\frac{9680}7$ units per second. Now you got the linear speed, just find out the time by dividing the distance by the speed!
So, what's the unit for the radius?
