$130.80
$87.20
$21.80
$78.20
Answer:
The answer would be $87.20
Step-by-step explanation:
Because if it is 20 % off you would multiply it by 0.2 which would get you 21.8
Then, 109 - 21.8 is 87.20

Answer:
5.33 or 5[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Assuming you don't want the answer in decimals, this is the process to find the answer in fractions:
1 [tex]\frac{2}{5}[/tex] + (3 [tex]\frac{1}{3}[/tex] + [tex]\frac{3}{5}[/tex])
= [tex]\frac{7}{5}[/tex] + [tex]\frac{10}{3}[/tex] + [tex]\frac{3}{5}[/tex] → convert into mixed fractions
= [tex]\frac{21}{15}[/tex] + [tex]\frac{50}{15}[/tex] + [tex]\frac{9}{15}[/tex] → find the least common denominator to make them the same
= [tex]\frac{80}{15}[/tex] = 5[tex]\frac{5}{15}[/tex] = 5[tex]\frac{1}{3}[/tex] → = add and simplify
Sam decided to go to the amusement with his sister. He paid $10 for parking and $12.50 per ticket. Determine the y-intercept. Write your answer as an ordered pair (x,y).
Answer:
[tex]y= 10+12.5x[/tex]
Step-by-step explanation:
Given data
He paid $10 for parking and
$12.50 per ticket.
let the number of tickets be x
and let the total cost be y
Hence the expression in terms of x and y is
[tex]y= 10+12.5x[/tex]

Show that the lines
y = 4x + 2 and 8x + 2y = -3 are parallel
help pls asap ty ! ! !
Answer:
They intersect
Step-by-step explanation:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.
Here we have two functions:
1) y = 4x + 2
2) 8x + 2y = - 3
2y = - 8x - 3
// divide both sides by 2
y = - 4x - 1,5
- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.
(a) Reflect the point (5 3) across the x-axis:
(b) Reflect the point(5 3) across the y-axis:
Answer:
(5, -3)
(-5, 3)
Step-by-step explanation:
Reflecting across the x-axis makes the y coordinate change from a positive to a negative and reflecting across the y axis makes the x value negative.
Y=91 if x is 4 what is y

Part A
Using opposite operations, rewrite the equation so s2 is on one side of the equation by itself.
Part B
What is the opposite operation of squaring? Using this opposite operation, rewrite the equation from question 1 so s is by itself on one side of the equation.
Part C
The pyramid of Khufu, also known as the Great Pyramid of Giza, is one of the Seven Wonders of the World. Its volume is about 2,433,400 cubic meters, and its height is about 138 meters. Substitute these values into the equation from Part B, and solve the equation.
Part D
Search the Internet to find the length of each side of the base of Khufu’s pyramid. Does this length match your calculation?
Part E
Khafre was a son of Khufu. He also had a pyramid built, but it was not as big as his father’s. The volume of the Pyramid of Khafre is about 2,115,072 cubic meters, and its height is about 136 meters. Approximate the length of each side of the base?
Part F
Search the Internet to find the length of each side of the base of Khafre’s pyramid. Does this match your calculation?
Part G
About how much longer are the side lengths of the base of Khufu’s pyramid than Khafre’s?
Answer:
Part A: S^2= 3V/H
Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]
Part C: s=√3* 2,433,400 /138=230 metres
Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.
Part E: S = √3*2,115,072/ 136 =216 metres
Part F: The length of Khafre's pyramid is about 215.5 My calculation was a little off, but not by much.
Part G: 14 meters longer
Step-by-step explanation:
Part A:
I am going to solve:
So,
V=1/3 [tex]HS^{2}[/tex]
Then, multiply both sides by 3:
V x 3= 1/3 [tex]HS^{2}[/tex] x 3
So,
3V=[tex]HS^{2}[/tex]
Then, we divide by H:
[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]
So,
[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]
Then switch sides:
[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]
I hope this helps!

Roy and two friends are at a game center. Each person buys hot dogs for $3, fries for $2.49, and a drink for $2.50. They also have a coupon for $1 off each drink. Write an expression to represent the total cost. Then find the total cost.
Answer:
$20.97
Step-by-step explanation:
3 people, meaning to multiply each one by 3.
Total price of Hot Dogs= 9.00
Total price of Fries=7.47
Total price of Drinks=7.50
7.50 - 3= $4.50
9.00+7.47+4.50= $20.97
Eight bowls cost $160, but Adrien wants only 5 of them so how much does he have to pay?
Answer:
$100
Step-by-step explanation:
you have eight bowls so you divide 160 by 8 and you get 20 so each bowl is 20 so 5x20=100
Answer:
100
Step-by-step explanation:
First, calulate the cost of each bowl, so, 160/8=20
Next, calculate how much total it costs, so 20x5, which the answer is $100

Determine the common factors and HCF for each of the following terms.
b) 2b, 3b
e) 5bc, 2c2, 3cd
f) 4a2b, 8b2c, 6bcd
Help please and explanation..
Answer: Please see explanation column for answers
Step-by-step explanation:
When a number divides into another number without a remainder, it s called a factor of that number. Lets say we want to find the common factors of two numbers, we get the factors of each one and compare them. The common factor is the one that is found in both lists
While The Highest common factor, is the highest factor number found in both lists.
b) 2b , 3b
Factors of 2b= 1, 2 and b
Factors of 3b=1, 3 and b
Common factors =1 and b
HCF=1b
e) 5bc, 2c2, 3cd
Factors of 5bc= 1, 5, b, c
Factors of 2c2= 1, 2, c, c2
Factors of 3cd= 1, 3, c, d
Common factors = 1 and c
HCF= 1c
f) 4a2b, 8b2c, 6bcd
Factors of 4a2b= 1, 2, 4, a, a2, b
Factors of 8b2c= 1, 2, 4, 8, b, b2, c
Factors of 6bcd= 1, 2,3,6, b, c,d
Common factors = 1, 2 , b
HCF= 2b
A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students

Solve the inequality.
8(x - 2) + 9<3(x - 1) + 5x
A. x <-7
B. X<-3
C. no solution
D. all real numbers
Answer:
D
Step-by-step explanation:
All real numbers are solution
Step 1: Simplify both sides of the inequality.
8x−7<8x−3
Step 2: Subtract 8x from both sides.
8x−7−8x<8x−3−8x
−7<−3
Step 3: Add 7 to both sides.
−7+7<−3+7
0<4

A car travels 160 miles in 4 hours. At this rate, how far will the car travel in 7 hours?( find unit rate,
then multiply by 7)
Answer:
280
Step-by-step explanation:
160 divided by 4 is 40 then times that by 7 and u get 280
Answer:
280 miles
Step-by-step explanation:
First you have to find how many miles a car travels in 1 hour. (160 ÷ 4 = 40).
Then, once you find that, you multiply 40 by 7. (280)
Hope this helps!
