$3.616
Step-by-step explanation:
At the restaurant, the cost of the meal before tax was $40. The tax is 8.5%, and Sheri wants to leave at least an 18% tip. Explain how to approximate the total cost of the meal.
Solution :-
given that,
→ Cost of meal before tax = $ 40
and,
→ Tax = 8.5%
So,
→ Total tax paid = 8.5% of cost of meal = (40 * 8.5)/100 = $ 3.4
now,
→ Tip = 18% of cost of meal = (18 * 40)/100 = $ 7.2
then,
→ Total cost of the meal = Cost of meal before tax + Total tax paid + Tip = 40 + 3.4 + 7.2 = $50.6 ≈ $51 (Ans.)
Shortcut :-
→ Total cost of the meal = Cost of meal * (100% + 8.5% tax + 18% tip) = 40(1 + 0.085 + 0.18) = 40 * 1.265 = $50.6 ≈ $51 (Ans.)

The required relation whose constant of proportionality matches with the constant of proportionality given in the graph.
Given that,
A curve is shown in the graph, it is to be determined that the constant of proportionality of the curve matches one of the curves given in the options.
Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense that are they directly proportional or inversely proportional to each other.
Here,
Constant of proportionality for the given function,
y/x = 2 / 8 = 0.25
Since the constant of proportionality of the functions mentioned in Option A, C and E matched with the given graph.
Thus, the required relation whose constant of proportionality matches the constant of proportionality is given in the graph.

Each football costs the same amount, and each basketball costs the same amount. At the first store, the coach paid $110 for 5 footballs and 14 basketballs. At the second store, the coach paid $82.50 for 10 footballs and 6 basketballs. What was the cost in dollars of each basketball?
Answer:
$6.25
Step-by-step explanation:
Each football costs the same amount, and each basketball costs the same amount.
Let the cost of:
Footballs = f
Basketballs = b
Hence, we have the following system of equations
At the first store, the coach paid $110 for 5 footballs and 14 basketballs.
5f + 14b = 110
At the second store, the coach paid $82.50 for 10 footballs and 6 basketballs.
10f + 6b = 82.50
What was the cost in dollars of each basketball?
5f + 14b = 110..... Equation 1
10f + 6b = 82.50.....Equation 2
We solve using Elimination method.
Multiply Equation 1 by 10 and Equation 2 by 5 to eliminate f
50f + 140b = 1100.... Equation 3
50f +30b = 412.5.......Equation 4
Subtract Equation 4 from Equation 3
110b = 687.5
b= 687.5/110
b = $6.25
Therefore, the cost of one basketball in dollars = $6.25

T is the midpoint of segment SU. If ST= 17x and TU= 7x + 39 Find the value of x.
Answer:
[tex]\displaystyle x=\frac{39}{10}[/tex]
What is the midpoint?The midpoint of a line bisects that line into two congruent line segments - otherwise speaking, they are equivalent to each other.
Due to this, we can set the equations equal and solve for x.
SolveFirst, set the equations equal to one another.
[tex]17x = 7x + 39[/tex]
Subtract 7x from both sides of the equation to combine like terms.
[tex]17x - 7x = 7x - 7x + 39[/tex]
[tex]10x =39[/tex]
Then, divide both sides of the equation by 10 to isolate the variable.
[tex]\displaystyle \frac{10x}{10} = \frac{39}{10}[/tex]
[tex]\displaystyle x=\frac{39}{10}[/tex]

4 thumb drives and 1 compact disk have a
total capacity of 18 gigabytes. 3 compact
disks and 4 thumb drives have a total
capacity of 22 gigabytes. Find the capacity
of 1 thumb drive (x) and the capacity of 1
compact disk (y).
The capacity of thumb drive disc is 4 gigabytes and the capacity of compact disc is 2 gigabytes.
How to calculate the equation?Let thumb drive = (x)
Let the capacity of 1 compact disk = (y).
Therefore, the appropriate equation will be:
4x + y = 18
4x + 3y = 22
Subtract the equations
2y = 4
y = 4/2
y = 2
The capacity of compact disc is 2 gigabytes.
Since 4x + y = 18
4x + 2 = 18
4x = 18 - 2
4x = 16
x = 16/4
x = 4
The capacity of thumb drive disc is 4 gigabytes.

The coordinates of point T are (0,5). The midpoint of is (2,-5). Find the coordinates of point S.
The coordinates of point S is (4, -15)
How to find the coordinates of point S?The given parameters are
T = (0, 5)
Midpoint = (2, -5)
The midpoint of a line is calculated using
Midpoint = 1/2 * (x1 + x2, y1 + y2)
So, we have
(2, -5) = 1/2 * (0 + x, 5 + y)
This gives
(4, -10) = (x, 5 + y)
Solve for x and y
So, we have
x = 4
5 + y = -10
This gives
x = 4
y = -15
Hence, the coordinates of point S is (4, -15)
