to have 2.40$ between 30 dimes and nickels she would have to have 18 dimes being 1.80$ and 12 nickles being .60 cents.
In order for two lines to be perpendicular, their slopes must multiply together to equal to negative one
So we do negative one divided by 2/5 to get the slope of the red line
Which is -5/2
To check, we do 2/5 multiplied by -5/2 which equals to -1 so our answer is correct

Answer:
V = 314
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
r = 5
h = 12
Work:
V = πr²(h/3)
V = 3.14(5²)(12/3)
V = 3.14(25)(4)
V = 314
