Answer:
6233500
Step-by-step explanation:
We are given that CEO of a company that sells car stereos has determined the profit x number of stereos.
The profit of selling x number of stereos is given by
We have to find the value of profit when the company selling 12500 stereos.
Substitute the value of x=12500
Then, we get
Hence, the company should expect profit 6233500 from selling 12500 stereos.
Yeah y=9
hope this helped even tho I’m kinda late haha
Answer:
Hamburgers + Cheeseburgers= 390
Hamburgers= x
Cheeseburgers= 2x
2x+x= 390
3x=390
x=130
Hamburgers sold= 130
Answer:
fourth option
Step-by-step explanation:
A translation of 6 units right ( positive x- direction ) means add 6 to the original x- coordinate.
A translation of 2 units down ( negative y- direction ) means subtract 2 from the original y- coordinate.
Thus the translation rule is
(x, y ) → (x + 6, y - 2 )
Surface area of cylinder is 2 (pi)rh+2(pi)r^2
this is the area of the side [(2 (pi)rh] and the two circles together [2 (pi)r^2]
122. r=24
h=15
2 (3.14)24×15+2 (3.14)24^2

124. the surface area of a cylinder that has a hole is going to be
surface area of big cylinder-2small area circles (the holes) + the area of the holes sides
hopefully that isn't too confusing
big radius: 8
height: 14
little radius: 2.5
height: 14
2 (3.14)8×14+2 (3.14)8^2
6.28×8×14+6.28×8^2

125. h=20
r=6 since diameter is a foot or 12 in, half of that is 6
2 (3.14)6×20+2 (3.14)6^2
6.28×6×20+6.28×6^2

126. first radius= 10
first height = 6
second radius= 6
second height= 10
2 (3.14)10×6+2 (3.14)10^2

1004.8-602.88= 401.92
the surface area of the cylinder with radius 10 and height 6 is GREATER that the surface area of the cylinder with radius 6 and height 10..
by 401.92in
