Answer:
25 students
Step-by-step explanation:
Let t= total students
Take the total number of students and multiply by the percent that are boys to get the number of boys
t * 40% = 10
Change to decimal form
t*.40 = 10
Divide by .4 on each side
.40t /.4 = 10/.4
t =25
There are 25 students
Attached is a plot of the base with one of the cross sections (at
).
The area of any one cross section is given by
, where
is the radius of the circular cross section. In terms of the sections' diameters
, the area would be
.
Each section's diameter is determined by the vertical distance (in the x-y plane) between the curve
and the x-axis (
), or simply
. So the area of any one cross-section for a given
is
.
The region extends from
to
(the positive root of
), so the volume of the solid would be
You can compute this by expanding the integrand, then integrating term by term. You should find a volume of
.
Answer: 1 + 1 = 2
Step-by-step explanation:because that's how we've defined it, in the same way that the word "cat" refers to small, furry, feline creatures because that's how we've defined it.
In base 16, C = 12 and D = 13, so
CD₁₆ = 12•16¹ + 13•16⁰ = 205₁₀
