*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.

PLEASE HELP ASAP Find the value of x.
Answer:
x = 9
Step-by-step explanation:
The secant- secant angle 4x° is half the difference of the intercepted arcs, that is
4x = [tex]\frac{1}{2}[/tex] (9x + 26 - 35 ) ← multiply both sides by 2 to clear the fraction
8x = 9x - 9 ( subtract 8x from both sides )
0 = x - 9 ( add 9 to both sides )
9 = x
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

A desk drawer contains 8 blue pens, 7 black pens, and 10 green pens. Lawrence will randomly choose one item from the drawer. What is the probability Lawrence will choose a green pen?
Answer: [tex]\dfrac{2}{5}[/tex]
Step-by-step explanation:
Given
A desk drawer has 8 blue, 7 black, and 10 green pens
The favorable chances of drawing a green pen are 10
Probability is given by the ratio of favorable outcomes to the total outcomes.
So, the probability of drawing a green pen is
[tex]\Rightarrow P=\dfrac{10}{8+7+10}\\\\\Rightarrow P=\dfrac{10}{25}\\\\\Rightarrow P=\dfrac{2}{5}[/tex]

What is the value of x
Answer:
x = 36.03°
Step-by-step explanation:
We have to find: Angle A, also called "x
We are given: Side opposite to x and the hypotenuse of the triangle.
Trigonometric Ratio that would be used: Sin
=> Sin(x) = Opposite/Hypotenuse
=> Sin(x) = 10/17
=> x = Sin⁻¹(10/17)
=> x = 36.03 Degrees

Una mamá tiene el cuádruplo de la edad de su hijo, y dentro de 5 años, tendrá el triple de años que el. Indica que edad tienen ambos.
Answer:
The son age is 10 years
And, his mother age be 40 years
Step-by-step explanation:
Given that
The mother is four times the age of her son
And, in 5 years, she will be three times as old as him
We need to find out the ages of both
Here we assume that the age of her son be x
So the mother age be 4x
Now in 5 years, her mother would be 3 times as old as his son
So,
4x + 5 = 3(x + 5)
4x + 5 = 3x + 15
x = 10
The son age is 10 years
And, his mother age be 40 years

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
