*40 people responded that they use mouthwash.
*Of the people who use mouthwash, 30 people use floss.
*55 people responded that they do not floss.
*45 people responded that they don't floss and don't use mouthwash
Answer: The image of the completed table is shown below
In the completed table, we have the following values (left to right)
Row One: 30, 10, 40Row Two: 15, 45, 60Row Three: 45, 55, 100==============================================
Explanation:
We're told that "40 people responded that they use mouthwash". That means we'll write "40" at the very end of the "use mouthwash" row. This represents the total number of people who use mouthwash, since we're underneath the "total" in that far right column.
Then we're further told that "Of the people who use mouthwash, 30 people use floss", so we'll write "30" in the first row, first column blank space. These are the people who both floss and use mouthwash. Because earlier we know 40 people use mouthwash overall, this leaves 40-30 = 10 people who use mouthwash, but they don't floss.
To summarize so far: In row 1, we have the following values from left to right: 30, 10, 40
The first two items of this row must add to the last item.
---------------------
Now onto row 2
Since 40 people use mouthwash, and 100 people were surveyed, this means that 100-40 = 60 people do not use mouthwash. The value 60 goes at the very end of row 2. This represents another total.
Like earlier, the first two items must add to the last. So 40+60 = 100.
Now turn to the fact that "45 people responded that they don't floss and don't use mouthwash". This tells us that "45" will be in the "no mouthwash" row and "don't floss" column.
We have 60 people who don't use mouthwash, and 45 of those people also don't floss. Therefore, 60-45 = 15 people do floss but they don't use mouthwash. We'll write "15" in the second row, first column.
Along row 2, we have the following values: 15, 45, 60
----------------------
Row 3
For each column, add up the first two items to get the third one. This will lead to the totals along this bottom row.
Floss: 30+15 = 45Don't Floss: 10+45 = 55 .... note how this matches up with the third piece of information your teacher providedThe third column is already done, but again we can see that 40+60 = 100.
Furthermore, the first two items of the third row add to 45+55 = 100 which helps confirm our answers.
The full completed table is shown below.
------------------------
To summarize, we are effectively just sorting the values given to us to write them into the table. Then we use a bit of algebraic detective work to find out what values are missing so we fill out the completed table.

Miko and her parents rent boats for the afternoon. Her parents rent a canoe and Miko rents a kayak. • It costs $20.49 to rent a canoe plus an additional $7.49 for each hour. • It costs $17.99 to rent a kayak plus an additional $5.99 for each hour. Miko and her parents rent one canoe and one kayak for the same amount of time, and their total cost for the rentals is $78.92. Write and solve an equation to determine the amount of time, in hours, that they rented the kayak and canoe.
Answer:
Kayak and Canoe rented for 3 hours
Step-by-step explanation:
Let the time for which they rent canoe & kayak = x hours
Total canoe cost = 20.49 + 7.49x , Total kayak cost = 17.99 + 5.99x
Given] Total canoe & kayak cost = 78.92
So, (20.49 + 7.49x) + (17.99 + 5.99x) = 78.92
20.49 + 17.99 + 7.49x + 5.99x = 78.92 ; 38.48 + 13.48x = 78.92
13.48x = 78.92 - 38.48 ; 13.48x = 40.44
x = 40.44 / 13.48 ; x = 3

Step-by-step explanation:
The other legs of the right-angle triangle will be 12.23 units and 11.81 units.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The right angle triangle is shown with the angle of 44° and the length of the hypotenuse is 17 units.
Then the measure of the length of x will be given by a cosine angle of 44°.
cos 44° = x / 17
x = 12.23 units
Then the measure of the length of y will be given by a sine angle of 44°.
sin 44° = y / 17
y = 11.81 units
Thus, the other legs of the right-angle triangle will be 12.23 units and 11.81 units.

the equation s = p - 0.15 represents the sale price s of an item with an original price p, after a 15% discount. A T-shirt costs $12. What is the sale price?
Answer:
S = $10.20
Step-by-step explanation:
s = 12 - .15 (12)
s = 12 - 1.80
s = $10.20
If 15% comes off the price, then 85% of the price is left to pay. (100 - 15 = 85)
12 x .85 = $10.20

help please! quadratic equation and stretch factor
Answer:
Equation: f(x)=x²-4x+3
Stretch factor: a=1
Step-by-step explanation:
Notice the x-intercepts are (1,0) and (3,0) which can help us determine the equation by setting their expressions equal to 0 and expanding:
(x-1)(x-3)=0
x²-4x+3=0
Therefore, the equation is f(x)=x²-4x+3 where the stretch factor is a=1

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Clayton gets paid at home for doing extra chores. Last week, he did 4 loads of laundry and 5 loads of dishes, and his parents paid him $14. The week before, he finished 4 loads of laundry and 10 loads of dishes, earning a total of $24. How much does Clayton earn for completing each type of chore? Clayton earns $ per load of laundry and $ per load of dishes.
Answer:
$1.00 per load of laundry, $2.00 per load of dishes
Step-by-step explanation:
4($1.00) = $4
5($2.00) = $10
This equals $14, when he does 10 loads of dishes the number changes to $20 and by adding $20 to $4, that equals $24.
The answer is $1.00 per a load of laundry, $2.00 per load of dishes
