Answer:
Variable d represents the time per minute Lilianna spends in the park.
Step-by-step explanation:
Lilianna uses 
calories per minute just by sitting. She uses 1 more calorie per minute by walking.
Liliana uses a total of 
calories walking to the park.
Lilianna uses the equation, 
to represent the situation.
Here, variable d represents the time per minute she spends in the park.
and is given as,
It can be written as,
Solving for d,
Thus, she spend d= 7 minutes total to the park.
16 gal... 480 mi
1 gal... 480/16 = 30 mi
9 gal.. 30*9 = 270 mi
Answer:
26π, 130π, 780π (inches)
Step-by-step explanation:
We first need to find how long the circumference of the circle is, since that is the part of a wheel that determines how far it will go. The formula to find the circumference is 2πr, where r is the radius. This formula is just something you have to remember, there is no way around it.
Now, applying the formula, we find that the diameter of the circle is 26π inches, which means that the bike will go 26π inches every rotation of the wheel.
To find the distance for 5 rotations, we multiply 26π by 5, getting 130π
Similarly, with 30 rotations, we get 26π*30=780π
Answer:
15.4z - 12
Step-by-step explanation:
Distribute:
=7.4z + (−5)(−1.6z) + (−5)(2.4)
=7.4z + 8z + −12
Combine Like Terms:
=7.4z + 8z + −12
=(7.4z+8z) + (−12)
=15.4z + −12
