QUESTION Lin’s father is paying for a $20 meal. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied.
how much does lin father pay for the meal
Answer:
18.19
Step-by-step explanation:
First we must determine how much 15% of 20 is (3). Now we must subtract that from 20 (20-3=17$) Once we have that we must figure out how much 7% of 17 is ($1.19) Lastly, we must add the tax to 17.00 (17+1.19) to get 18.19.

A right triangle is ____ a scalene triangle.
Always, sometimes, or never
Answer: Sometimes
Step-by-step explanation:
This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas

Factor 72x−18xy
Find the Factor of 72x-18xy
Answer:
4x and (1-y)
Step-by-step explanation:
4x(1-y)
this is my answer
The factors of the expression are 18x and 4-y
Given the expression 72x - 18xy
Find the factor of each term:
72x = 18 * 4 * x
18xy = 18 * x * y
Since 18x is common to both terms, hence the factored form is expressed as:
72x - 18xy = 18x (4 - y)
The factors of the expression are 18x and 4-y

c = s (which is unknown)
plugin values into the formula:
a² + b² = c²
8² + 15² = s²

Mr. Hudson's bill when taking his family to a restaurant for dinner was $65. He used a discount card for 15% off and left a 20% tip on the original amount of the bill. Complete the statements to determine how much Mr. Hudson spent at the restaurant. The amount of Mr. Hudson's bill after the 15% discount was $ . Mr. Hudson left $ for a tip. Mr. Hudson spent $ at the restaurant.
Answer:
Amount of bill after discount = $55.25
Amount of tip left = $13
Total money spent at the restaurant = $68.25
Step-by-step explanation:
Original bill amount of Mr. Hudson = $65
Discount card value = 15% of the bill
Tip offered = 20% of the original amount
To find:
Amount of bill after the discount of 15%.
Amount of tip left.
Total amount spent in the restaurant.
Solution:
Let us apply the percentage here to find the values of total discount, total tip offered.
Discount = 15% of $65
[tex]\Rightarrow \dfrac{15}{100} \times 65 = \$9.75[/tex]
Amount of bill after discount = $65 - $9.75 = $55.25
Amount of tip left = 20% of $65
[tex]\Rightarrow \dfrac{20}{100} \times 65 = \$13[/tex]
Total money spent at the restaurant = Amount of bill after discount + tip offered = $55.25 + $13 = $68.25
The answers are:
Amount of bill after discount = $55.25
Amount of tip left = $13
Total money spent at the restaurant = $68.25
A watering can dispenses water at the rate of 0.3 gallon per minute. The original volume of water in the can was 7 gallons. Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water? (1 point)
{(1, 6.7), (2, 6.4), (3, 6.1)}
{(1, 7.0), (2, 6.7), (3, 6.4)}
{(6.7, 1), (6.4, 2), (6.1, 3)}
{(7.0, 1), (6.7, 2), (6.4, 3)}
Answer:
The correct ordered pairs are:
{(1, 6.7), (2, 6.4), (3, 6.1)}
Option A is correct.
Step-by-step explanation:
A watering can dispenses water at the rate = 0.3 gallon per minute
The original volume of water in the can = 7 gallons.
Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water?
First making the function:
The the volume of water in the can in gallons is represented by y and time in minutes is represented by x. Initially the volume is 7 gallons, after than water dispense at rate of 0.3 gallon per minute so, the function will be:
y=7-0.3(x)
Now, putting values to find ordered pairs
So, when time is 1 minute i.e x = 1
y=7-0.3(1)
y=7-0.3
y=6.7
So, when x=1, y=6.7 the ordered pair is: (1,6.7)
when time is 2 minutes i.e x = 2
y=7-0.3(2)
y=7-0.6
y=6.4
So, when x=2, y=6.4 the ordered pair is: (2,6.4)
when time is 3 minutes i.e x = 3
y=7-0.3(3)
y=7-0.9
y=6.1
So, when x=3, y=6.1 the ordered pair is: (3,6.1)
So, the correct ordered pairs are:
{(1, 6.7), (2, 6.4), (3, 6.1)}
Option A is correct.

A function can't have two X values that are the same (If I remember correctly) and the second table is the only one that doesn't have duplicated X values
Answer:
the correct answer is b
Step-by-step explanation:
line passes through points (5, 8) and (10, 5). Line b is parallel to line a. what is the slope of line b??
Answer:
-3/5
Step-by-step explanation:
Let's go from the point (5, 8) to the point (10, 5). We can see immediately that x (the 'run') increases by 5 and y (the 'rise') decreases by 3. Thus, the slope of the line connecting these two points is m = rise/run = -3/5.
Both of these lines have the slope -3/5, given that they are parallel lines.

Answer:

-7
Step-by-step explanation:
0 x any number = 0
4(-5) = -20
126/(-18) = -7
Answer:
1. 0
2. -20
3. -7
Step-by-step explanation:
1. 0 times anything is equal to nothing times something.
So, the first one is 0.
2. For 4 x -5, you can just do 4 x 5 x -1, which equals 20 x -1, whixh equals -20.
3. Remember, a negative times a negative = a positive. So, the number must be negative. Just do 126 / 18 x -1, which equals -7.

(dont write random answers pls)
look at the pic attached:
Answer
the answer would be
D(5,-2).
Answer:
D(-6, 1)
Step-by-step explanation:
To determine the solution we can start by calculating the slope of AB;
A(-1, 4), B(2, -5)
m = -5 - 4 / 2 - (-1) = -9 / 3 = -3
Then CD, if to be perpendicular, should have the 'negative reciprocal' of the slope of AB. In other words it should have a slope of 1/3. We are given point C as (3, 4) so let's take each of the given options for point D, and find the slope using the two points. If the slope is 1/3rd then that is the correct option.
Now I already know the answer, so instead of going through all the options I will just check the slope with the correct answer choice. You will find the slope to be 1/3rd;
C(3, 4), D(-6, 1)
m = 1 - 4/- 6 - 3 = -3/-9 = 1/3rd
Correct, as you can see
So your solution is option c
