R=number of hours ruby worked
i=number of hours issac worked
s=number of hours shetland worked
ruby worked 8 more than issac
r=8+i
shetland worked 4 times as many as ruby
s=4r
total they worked 136
r+i+s=136
so
we gots
r=8+i
s=4r
for r=8+i
solve for i
minus 8 both sides
r-8=i
so
r+i+s=136
subsitute r-8 for i and 4r for s
r+r-8+4r=136
6r-8=136
add 8 to both sides
6r=144
divide both sides by 6
r=24
sub back
r-8=i
24-8=i
16=i
s=4r
s=4(24)
s=96
ruby worked 24 hours
issac worked 16 hours
shetland worked 96 hours
Answer: 2
Step-by-step explanation:
24 divided by 3 is 8 so 1 stick of butter makes 8 cookies so 2 sticks of butter make 16 cookies(2 x 8)

Answer:
(b) 10.5 in
Step-by-step explanation:
The formula for the volume of a cone is ...
V = 1/3πr²h . . . . . . for radius r and height h
Then the height is ...
h = 3V/(πr²)
Your cone has a volume V = 199 in³ and radius r = 4.25 in, so the height is ...
h = 3(199 in³)/(π(4.25 in)²) ≈ 10.52 in
The height of the cone is about 10.5 inches.
Assuming you are asking how many weeks, than the answer would be 17-32, because at 16 weeks the growth would be 4 cm, totaling at 11, but you need more than 11cm, and at 32 weeks it's at 15 cm.
Answer:
3 = f
Step-by-step explanation:
3(6 - f) - 4 = 3f - 4
Distribute within Parenthesis
18 - 3f - 4 = 3f - 4
Combine like terms
14 - 3f = 3f - 4
Add 3f on both sides of the equation
14 = 6f - 4
Add 4 on both sides of the equation
18 = 6f
Divide by 6 on both sides of the equaiton to get your answer of
3 = f
Hope this helps :)
