A cone is 1/3 the volume of a cylinder, so if the cone is 258.9, we should multiply by 3 is get the cylinder's volume:
258.9 times 3 = 776.7
When answering questions like these, it helps to draw arrows,, the variable will always be on top, so in this situation you would draw an arrow from the a to the 10 and an arrow from the 38 to the 12 making them both fractions, you would then cross multiply, after cross multiplying you would get 12a=380 then you would divide by 12 equaling 31.6
False
I think that’s right because three times 5 is 15 increased by four is 19 not -8 so...
She could estimate that there would be about 148 million female drivers.
From her data, she found there were 118 females drivers out of the total 200 drivers that she counted.
That is 118 out of 200 or 0.59 or 59%.
Now, just take 59% of 250.
0.59 x 250 = 147.5 which rounds to 148.
Hello from MrBillDoesMath!
Answer:
@ = pi/3 (or 60 degrees) or @ = 7 pi/3 (or 420 degrees)
Discussion:
Let "@' denote the angle "theta". We are asked to find @ in the interval [0, 4 pi)
where
4cos(@) - 2 = 0. Adding 2 to both sides
4 cos(@) - 2 +2 = 2 =>
4 cos(@) = 2 Divide both sides by 4
cos(@) = 2/4 = 0.5
This implies that @ = pi/3 (or 60 degrees) or @ = (pi/3 + 2pi) = 7 pi/3 (or 420 degrees)
Thank you,
MrB
