Kinetic engery = -1/2mv^2
Work = Fd
Combine:
-1/2mv^2 - Fd = 0
-1/2mv^2 = (0.30*15000*9.81*cos(6))d = 0
Multiply both sides by 2:
v^2 = 2d(0.30*9.81*cos(6))
Solve for d:
d=v^2 / 2(0.30*9.81*cos96))
v = speed:
d = 35^2 / 2*0.30 * 9.81 * cos(6)
d = 1225 / 5.85376
d = 209.27 meters. Round answer as needed.
Okay so there are 100 white balloons, 200 pink balloons, and we are specified that the ratio of pink to yellow is 10:1 soo we can plug 200:20 which can be simplified to 100:10 which can then be simplified to 10:1 there is our ratio. So there are 29 yellow balloons. Therefore there are only 80 balloons left which would mean there are 80 blue balloons!:)
The quotient is -8. This being because when a negative number is in parentheses, the negative will be the opposite: Positive. And we know 48 divided by 6 is 8. So the answer is B.
Hey -- I'll answer it for you but my vision is not that great... Could you just type the question in a reply, or DM it to me? Sorry, it's just really small on the picture, even when I tried to zoom it in.
Answer:
30.3
Step-by-step explanation:
First we find the area of the trapezoid. The formula for that is (b1+b2)/2(h)
2+10=12
12/2=6
6x4=24
To find the area of a semicircle we do πr²/2
2^2=4
4x3.14=12.56
12.56/2=6.28
24+6.28=30.28
That is extremely close to 30.3 so the paper must be a bit off.
