First make this:
x/90= 40/100 (percent)
Then cross multiply...(Don't know how to explain so search it up)
90x40= 3600
...then divide (by the remaining number)
3600/100=36 left handed players
Answer:
He began with 12.
Step-by-step explanation:
14-8=6
You need to multiply 6 because he sold half of his comic books at the beginning.
6*2=12
Answer:
Step-by-step explanation:
Remark
Assume all of the sheet of plywood is to be used.
Front and back = 2 * 2x *h
Top and Bottom = 2 * 2x * x
Left/Right side = 2 * x * h
Total area = 4xh + 4x^2 + 2xh
Total area = 6xh + 4x^2
Total area = 600
6xh + 4x^2 = 600
h = (600 - 4x^2)/6x
h = 100/x - 2/3 x
Volume = x * 2x * h
Volume = 2x^2 * (100/x - 2/3 x)
Volume = 200x - 4/3 x^3
I can do this without calculus (I think), but it is much easier to use it.
dV/dx = 200 - 4x^2
This is a maximum when dV/dx = 0
dV/dx = 200 - 4x^2 = 0
4x^2 = 200
x^2 = 50
x = 5√2
Slope-intercept form is:
y = mx + b
"m" being the slope, "b" being the y-intercept(when x = 0)
You first isolate the "y" in the given equation.
y - 2 = 3(x + 7) Multiply the 3 into (x + 7)
y - 2 = 3x + 21 Add 2 on both sides to get "y" by itself
y = 3x + 23
For the equation of the line to be perpendicular to the given equation, the slope has to be the opposite(you flip the sign and the number of the given slope)
For example:
slope = -2
the perpendicular line's slope = 1/2(positive)
slope = 4/5
the perpendicular line's slope = -5/4(negative)
The given slope is 3 or , when you flip the sign and the number, the perpendicular line's slope is
Now you need to find b, to do so you plug in the point (4,2) into the equation
Add 4/3 on both sides
Make the denominators the same
Your equation is:
There are no shaded regions below so we cannot find the value of these things
