The cost for filling the pool if the city charges $1.50 per 1000 gallons is $333.97
Given:
Length = 25 yd
width = 26 yd
Height = 5.1 ft
convert yard to feet
25 yd = 75 ft
26 ft = 78 ft
Volume of the pool = length × width× height
= 75 × 78 × 5.1
= 29,835 cubic ft
1 gallon = 0.134 cubic ft.
222,649.3 gallon = 29,835 ft
charges per 1000 gallon = $1.50
Total charges = 222,649.3 gallon / 1000 gallon × $1.50
= 222.6493 × 1.50
= 333.97395
Approximately,
$333.97
Therefore, the cost for filling the pool if the city charges $1.50 per 1000 gallons is $333.97

Step-by-step explanation:
To solve percent problems, you can use the equation, Percent · Base = Amount, and solve for the unknown numbers. Or, you can set up the proportion, Percent = , where the percent is a ratio of a number to 100.
Answer:
Base = Amount, and solve for the unknown numbers.Step-by-step explanation:
Or, you can set up the proportion, Percent = , where the percent is a ratio of a number to 100. You can then use cross multiplication to solve the proportion.
The school counselor needs to meet with students who have more than three absences. Here is some of the data about the students. Who are the individuals in this data set?

- 2 variables, 2 of which are quantitative
- 5 variables, 1 of which is quantitative
- 5 variables, 3 of which are quantitative
Answer:
The individuals in this data set are students. This data set contains 2 variables, 1 of which is quantitative.
Step-by-step explanation:
Individuals are the people or things described by a data set.
Variables are characteristics of the individuals that we measure or observe.
Categorical variables take on values that are labels or categories, and quantitative variables take on numerical variables.
The individuals described by this data set are students.
The characteristics listed--homeroom teacher and absences--describe each of the students, not teachers or counselors.
One of the variables--absences--is quantitative.
The individuals in this data set are students. This data set contains 2 variables, 1 of which is quantitative.

I have a red, blue, green, and yellow ball. If I put them all in a bag and pick one ball at a time (putting it back each time), what chance do I have of never picking a red ball, assuming I pick a color 40 times. Write as a decimal/percentage. (20 points! A good answer would be appreciated)
Answer:
Step-by-step explanation:
You have four balls
A draw of blue, green or yellow (3 balls) means success for NOT drawing a red ball
You have a 3 in 4 chance of not drawing a red ball on the first draw.
With replacement, the 3 in 4 chance occurs on every draw
the odds multiply together for each draw.
Chance of not drawing a red ball in 40 tries is (3/4)⁴⁰
or about 1 in 10⁻⁵ or 0.00001

Solve for the unknown values.
95x
50y
X=
degrees
y =
degrees
Answer:
x=85 degrees, y=45 degrees
Step-by-step explanation:
solve for x first:
because there is a straight line (meaning that the angle is 180 degrees), the sum of x and 95 must be 180.
x+95=180 so solving for x would result in x=85 degrees (180-95)
then to solve for y:
the total sum of the interior angles of a triangle is 180 degrees.
so if you know x and the given 50, then to solve for y:
50+85(angle x)+y=180
then solve for y to get 45 degrees (180-(50+85))

Answer:
C. (10 - 2) ÷ 4
Step-by-step explanation:
To determine which expression represent a number that is one fourth as great as 10-2 the following logical reasoning has to be made:
Given that a number is raised that is a quarter as large as (10-2), the result of this mathematical operation must be divided by 4.
Thus, since 10 minus 2 is equal to 8 and 8 divided by 4 gives 2, the division is necessary as a mathematical operation.
So, since the only option that raises a division is option C, that's the correct option.
