Answer:
Step-by-step explanation:
Let
y ----> the total cost for renting the popcorn machine
x ----> the time in hours
we know that
The total cost of renting a popcorn machine for 6 hours is $48
so
using proportion
Find out the total cost for renting the popcorn machine for x hours
Is a linear direct variation
The constant of proportionality or slope is equal to
That means ----> the total cost is $8 per hour
Answer:
65
Step-by-step explanation:
55 + 65 + 57 = 177
there are more factors, but I found this one the quickest.
hope this helps!
Shouldn't it be 19? 4+15=19 If it's wrong I have no clue.
The height of the trapezoid is
Explanation:
AKLM is a trapezoid.
The measurements of the trapezoid are AK=13, LM=14, KL=5, AM=20
We need to find the height of the trapezoid.
Let M' be a point on AM that is 5 units toward point A from M.
Let B be a point on AM such that KB⊥AM. Let x = AB; then BM' = 15 -x.
Using Pythagorean theorem, we have,
--------(1)
-----------(2)
Subtracting the two equations, we have,
Simplifying, we get,
Subtracting both sides of the equation by 225, we get,
Dividing by 30, we get,
Substituting in the equation , we get,
Thus, the height of the trapezoid is
