I believe this is right. But not 100%
Answer:
Fast car = 45.6
Slower car = 30.4
Step-by-step explanation:
Let the speed of the first car = x
Let the speed of the second car = y
Travelling towards each other.
x *1 + y*1 = 76 miles
x*5 - y*5 = 76 miles. This is kind of tricky. You have to understand that the first car that is 76 miles from the second car and makes up that 76 in 5 hours. The distance they both travel is subtracted out.
Divide by 5
x - y = 76/5
x - y = 15.2 The speeds differ by 15.2
x + y = 76
x - y = 15.2
2x = 91.2
x = 45.6
y = 76 - 45.6 = 30.4
When the two vehicles speeds are multiplied by 5, the difference is 76 km
Answer:
y= (x - 12)^3
y= (x - 4)^3
Step-by-step explanation:
Shift to the right is a horizontal shift so it needs to be with x in the parenthesis. And negative because it is to the right.
y= (x - 12)^3
y= (x - 4)^3
are the two that fit those criteria
We know that
[volume of a prism]=L*W*H
L=3 1/2 in-------> (3*2+1)/2--------> 7/2 in
W=3 1/2 in-------> (3*2+1)/2--------> 7/2 in
H=7 in
so
[volume of a prism]=(7/2)*(7/2)*7--------> 85.75 in³
[the difference in volume between the prism and the storage container]=90-85.75------------> 4.25 in³ (4 1/4 in³)
the answer is 4.25 in³ (4 1/4 in³)
