Answer:
1) x= -1/27
2) x=-4
3) x=13
Step-by-step explanation:
1) 7+7/9x= = -42
14/9x= = -42
14/9x X 9x= -42 X 9x
14= -378x
-378x= 14
-378x/-378= 14/-378
x= -1/27
2) 4x+1=−15
4x+1-1=-15-1
4x=-16
4x/4= -16/4
x=-4
3) −4(x−3)=−40
-4(x-3)/-4= -40/4
x-3=10
x-3+3=10+3
x=13

Answer:
A
Step-by-step explanation:
V = (0.04)*H (Company P)
V = (0.06)*H (Company S)
V represents the vacation hours and H is the hours worked
If they both work 2080 hours
V1 = (0.04)*(2080) = 83.2 vacation hours (Company P)
V2 = (0.06)*(2080) = 124.8 vacation hours (Company S)
124.8 - 83.2 = 41.6 hrs
There are many cones with a height of 12 inches. Let r represent the radius and V
represent the volume of these cones.
Plot points that show the volume when r=1, r=2, r=3, and .r=4.
HELP!
Answer:
If R = 1, ~12.57 is the y. (r is the x.)
If R = 2, ~50.27
If r = 3, ~113.1
If r = 4, ~201.06
Step-by-step explanation:
The formula of a cone is pi * r^2 * h/3
If r = 1, we have pi * 1^2 * 12/3
12/3 = 4
and 1^2 = 1
pi * 1 * 4
4 * pi = ~12.57
if r = 2, we have an imrpoved formula,
pi*2^2 * 4 (h/3 became 4 since 12/3 = 4)
2^2 = 4
4*4 = 16
pi * 16 = ~50.27
If r = 3
our formula is pi*3^2*4
3^2 = 9
pi*9*4
9*4 = 36
36* pi = ~113.1
If r = 4,
our formula is
pi*4^2*4
4^2 = 16 and 16*4 = 64
pi*64 = ~201.06.
Answer:
If R = 1, ~12.57 is the y. (r is the x.)
If R = 2, ~50.27
If r = 3, ~113.1
If r = 4, ~201.06

find surface area of the prism pls!!!!! explain too. I really need help!!!
Answer: 104 square inches
Step-by-step explanation:
The surface area of a prism is the sum of the surface are of all of it's faces.
We can turn that into this equation SA = 2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.
Substitute to get this: SA = 2(6 x 2) + 2(2 x 5) + 2(6 x 5)
Simplify with multiplication to get this: SA = 24 + 20 + 60
Simplify with addition to get this: SA = 104
Add the unit label and you get 104 square inches.
