Answer:
117.5 or 235/2
Step-by-step explanation:
We can set up an equation for this problem:
Lets Joe's weight be x
then:
2x -5 = 230
therefore:
2x = 235
x = 117.5 or 235/2
Answer:
820 ounces
Step-by-step explanation:
$2,460 divided by 3 = 820 ounces
820 x 3 = $2,460
Step-by-step explanation:
If the scale factor of two similar solids is a: b:. then
(1) the ratio of corresponding perimeters is a:b
(2) the ratio of the base areas, of the lateral areas, and of the total areas is 
(3) the ratio of the volumes is 
NUMBER 2 is 240 because 6 times 4 times 10 is equal to 240. I am still working on the others
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Step-by-step explanation:
interchanging the variables
x = 5y^2 + 10
5y^2 +10 = x
5y^2 = x - 10
dividing by 5
5y^2/5 = x/5 + -10/5
y^2 = x/5 + - 10/5
y^2 = x/5 - 2
y = 5 (x-10) 0/5 (sq.rt)
g(5x^2 + 10) = 5x/5
g(5x^2 + 10) = x
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
