A fast-food restaurant must apply an 8.5% tax on every sale it makes. How much tax must it charge a customer who purchases a total of $18.50 in food?
Answers
Answer: $1.57
Step-by-Step Explanation:
Study.com says: “the formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax,” (study.com, How to Calculate Sales Tax).
So, to find the amount of money they are charging for taxes, we need to use the formula: $18.50 x 8.5%. The selling price is the total sum of the purchase, and the sales tax rate is the percentage number that is apply to every sale as taxes.
Here’s how we solve:
1. To multiply, we first need to change our percentage into a decimal by dividing it by 100. —> 8.5/100 = 0.085
2. Multiply the purchase times the sales tax rate, which is converted into a decimal. —> 18.50 x 0.085 = 1.5725
3. Because money only uses the tenths and the hundredths places, we round up. —> 1.5725 ~ 1.573 ~ 1.57
4. Our answer for the tax amount charged in money is $1.57

The rectangular prism has a volume of 936 cubic inches. Write and solve an equation to find the missing dimension of the prism.
Answers
Step-by-step explanation:
A rectangular prism is nothing but a cuboid. Let the length , width and height of the rectangular prism be l, w and h.
We know that volume of a cuboid V = l×w×h
So, l×w×h = 936
So, we can find any dimension of the prism provided the the other two dimensions are given to us.

(4x+8) + (x+2)=180
5x+10=180

Find the trigonometric ratio as a fraction Tan N =
Find the trigonometric ratio as a fraction Tan L =
Answers
Answer:
Tan N = 4 / 3
Tan L = 3 / 4
Step-by-step explanation:
By Pythagoras theorem,
(LN)² = (MN)² + (LM)²
10² = 6² + (LM)²
100 = 36 + (LM)²
(LM)² = 100 - 36
(LM)² = 64
LM = 8
Tan N
= Opposite / Adjacent
= LM / MN
= 8 / 6
= 4 / 3
Tan L
= 1 / Tan N
= 1 / ( 4 / 3 )
= 3 / 4
Which graph represents a reflection of f(x) = 2(0.4)x across the y-axis? On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 2) and goes through (1, 5). On a coordinate plane, an exponential function decreases from quadrant 3 to quadrant 4 and approaches y = 0 in quadrant 3. It crosses the y-axis at (0, negative 2) and goes through (1, negative 5). On a coordinate plane, an exponential function decreases from quadrant 2 to quadrant 1 and approaches y = 0 in the first quadrant. It goes through the y-axis at (0, 2) and goes through (negative 1, 5). On a coordinate plane, an exponential function increases from quadrant 3 to quadrant 4 and approaches y = 0. It goes through (negative 1, negative 5) and crosses the y-axis at (0, negative 2).
Answers
The graph of g(x) is (a) an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 2) and goes through (1, 5).
The function f(x) is given as:
[tex]f(x) = 2(0.4)^x[/tex]
The rule of reflection over the y-axis is:[tex](x,y) \to (-x,y)[/tex]
This means that:
[tex]g(x) =f(-x)[/tex]
Substitute -x for x in f(x)[tex]f(-x) = 2(0.4)^{-x}[/tex]
Substitute the expression for f(-x) in the above equation [tex]g(x) =f(-x)[/tex][tex]g(x) = 2(0.4)^{-x}[/tex]
Hence, the graph of g(x) is graph (a)

Debra and Alexandria can finish a plowing job in two hours if they work together. Debra can do the job in 7 hours by herself. How long would it take Alexandria to finish the same job alone?
Answers
Answer:
2 hours 48 minutes
Step-by-step explanation:
Debra=1 plowing job / 7 hours
Debra+Alexandra=1 plowing job / 2 hours
1/2-1/7
=7/14-2/14
=5/14
=1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
14/5 hour=2 hours 48 minutes (hope hits helps)
Alexandria to finish the same job alone in, 2 hours 48 minutes
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Debra and Alexandria can finish a plowing job in two hours if they work together.
And, Debra can do the job in 7 hours by herself.
Hence, We get;
For Debra = 1 plowing job / 7 hours
Debra + Alexandra = 1 plowing job / 2 hours
Hence, Time to take Alexandria to finish the same job alone is,
= 1/2 - 1/7
= 7/14 - 2/14
= 5/14
= 1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
= 2 hours 48 minutes
Thus, Alexandria to finish the same job alone in, 2 hours 48 minutes

Using the Pythagorean theorem:
Hypotenuse = sqrt( 24^2 + 36^2)
Hypotenuse = sqrt(576 + 1296)
Hypotenuse = sqrt(1872)
