Answer:
$50
Step-by-step explanation:
Given data
Cost of sushi= $40
Tax= 5%
Tip= 20%
Let us find the amount of the tax and the tip
Tax
=5/100*40
=0.05*40
=$2
Tip
=20/100*40
=0.2*40
=$8
Hence the total amount paid is
=40+2+8
=$50
Answer:
$50
Step-by-step explanation:
To avoid confusion, we can solve for the sales tax and the tip separately.
Tip
Original Bill x 20%Original Bill x 1/5$40 x 1/5$8Tax
Original Bill x 5%Original Bill x 1/20$40 x 1/20$2Total
Original Bill + Tip + Tax$40 + $8 + $2$50A triangle has sides with lengths of 4 kilometers, 14 kilometers, and 16 kilometers. Is it a right triangle?

A right angle triangle will follow the PYTHAGORUS THEOREM. So the value found by adding the square of the two smaller sides should be same as the square of largest side.
what is the general rule of the following geometric sequence
-4; -1; -1/4
Answer:
Each of these numbers is divided by four to get the next number in the sequence, so the rule of this would be divide by 4.
Step-by-step explanation:
-4/4 is -1, -1/4 is -1/4 (negative one-fourth), and so on.
In UVW, u=51 inches,v= 61 inches and w= 62 inches.find the measure of angle V to the nearest degree
Answer:
49degrees
Step-by-step explanation:
Using the cosine rule
u² = v²+w²-2vwcosU
Substitute the given values
51² = 61²+62²-2(61)(62)cosU
2601 = 3721+3844-7564 cosU
2601 = 7565-7564cosU
-7564cosU = 2601-7565
-7564cosU = -4964
CosU =-4964/-7564
CosU = 0.6563
U = arccos(0.6563)
U = 49degrees(to nearest degree)
Four laps around the track is equal to one mile. It takes Taylor 8 minutes to run 3 laps.
How many minutes would it take Taylor to run 6 miles?
A. 16 minutes
B. 36 minutes
C. 48 minutes
D. 64 minutes
Answer:
D
Step-by-step explanation:
8x60=480
480÷3=160
160x4=640
640 is 10 Minutes 40 Seconds
6 Miles is 24 Laps
640x6=3840
3840÷60=64

John and Paul both run on the same track each morning. The ratio of the number of miles John runs to the number of miles Paul runs is 5:8.
Answer:
Step-by-step explanation:
For example,
Solution: Finding a unit rate
If we divide 150 by 20, we get the unit rate for the ratio, 150 minutes for every 20 miles.
150÷20=7.5
So the runner is running 7.5 minutes per mile. We can multiply this unit rate by the number of miles:
7.5 minutes mile × 6 miles = 45 minutes
Thus it will take her 45 minutes to run 6 miles at this pace.
If it takes her 45 minutes to run 6 miles, it will take her 45÷3=15 minutes to run 6÷3=2 miles at the same pace.
If it takes her 15 minutes to run 2 miles, it will take her 4×15=60 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.
We found her pace in minutes per miles in part (a).
Based on the lesson, identify the first operation needed to solve the following equation.
x/3 - 3 = 11
Answer:
The first operation is to add, and you are adding 3 to both sides of the equation to isolate the x.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. You are solving for the variable, x, when solving this equation.
Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
The first step is to add 3 to both sides of the equation:
(x/3) - 3 (+3) = 11 (+3)
(x/3) = 11 + 3
(x/3) = 14
The second step is to multiply 3 to both sides of the equation:
(x/3) * 3 = (14) * 3
x = 14 * 3
x = 42
42 would be your final answer.

Profit, P(x), is the difference between revenue, R(x), and cost, C(x), so P(x) = R(x) - C(x). Which expression represents P(x), if R(x) = 2x^4 – 3x^3 + 2x – 1 and C(x) = x^4 – x^2 + 2x + 3?
Answer:
x^4-3x^3+x^2-4
Step-by-step explanation:
Given the following functions
R(x) = 2x^4 – 3x^3 + 2x – 1 and
C(x) = x^4 – x^2 + 2x + 3
We are to find the profit function P(x)
P(x) = R(x) - C(x)
P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)
P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3
Collect the like terms
P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3
P(x) = x^4-3x^3+x^2+0-4
P(x) = x^4-3x^3+x^2-4
Hence the required profit function P(x) is x^4-3x^3+x^2-4
Answer:
x^4-3x^3+x^2-4

Find the length of the third side. If necessary round the nearest tenth
Answer: 16.5
formula:
c^2 = a^2 + b^2
(a and b are the lines that form a right angle and c is the line that doesn’t)
a = 16
c = 23
Answer:
16.5
Step-by-step explanation:
a² + b² = c²
x² + 16² = 23²
x² + 256 = 529
x² = 273
x = √(273)
x = 16.52271164...

The line plot below shows the amount of water ( in gallons) students drank in a week. What is the difference in the lowest amount of water and the highest amount of water students drank
The difference in the lowest amount of water and the highest amount of water students drank is 1/2
How to determine the difference?From the complete question (see attachment for line plot), we have:
Least = 1/8
Highest = 5/8
The difference is then calculated as:
Difference = Highest - Least
This gives
Difference = 5/8 - 1/8
Evaluate
Difference = 4/8
Simplify
Difference = 1/2
Hence, the difference in the lowest amount of water and the highest amount of water students drank is 1/2

Given that h varies inversely with respect to g, and that h= -24 when g= 3, write an
equation that describes the relationship between h and g. Then find h when g=-1,
Answer:
h = 72
Step-by-step explanation:
Given that h varies inversely with g then the equation relating them is
h = [tex]\frac{k}{g}[/tex] ← k is the constant of variation
To find k use the condition h = - 24 when g = 3 , then
- 24 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
- 72 = k
h = - [tex]\frac{72}{g}[/tex] ← equation of variation
When g = - 1 , then
h = - [tex]\frac{72}{-1}[/tex] = 72
