Answer: The required system of equations are
y = 30x
13x + y = 258
Step-by-step explanation:
Let x represent the number of hours
that the driver worked.
Let y represent the number of miles that the truck drove.
For every truck that goes out, Mason must pay the driver $13 per hour of driving and also has an expense of $1 per mile driven for gas and maintenance. If on a particular day, his total expenses for the driver, gas and truck maintenance were $258, it means that
13x + y = 258
On that particular day, the driver drove an average of 30 miles per hour.
Speed = distance/time
It means that
y/x = 30
y = 30x
Part A) means that we have to find a composition of functions A and m
A(m(t))=π(9t)²=9πt²
part B)
A(m(t))=9πt²
A(m(2))=9*3.14*(2)²=113.04
Answer:
<u>j = 2.5s</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Lemon juice (mL) Sugar (gr)
Batch A 500 200
Batch B 750 300
Batch C 1,500 600
2. Write an equation to describe the relationship between j, the amount of lemon juice in mL, and s, the amount of sugar in g.
Ratio = Amount of lemon juice/Amount of sugar
Ratio = 500/200 = 750/300 = 1,500/600
Ratio = 2.5
Now, we can write the equation, this way:
<u>j = 2.5s</u>
Tension seems the obvious answer here, but then we are left with x. Since the horisontal line on a graph is 'x'. The answer appears to be Tension X (Tension on X axis. Hope this helps.
