we will need at least 96 bags of sand to cover the base of the circular pool.

what is circle?

A circle is a two-dimensional geometric shape consisting of all the points that are equidistant from a given point, called the center.

The area of a circular pool with a diameter of 22 feet can be calculated using the formula:

A = πr^2

where A is the area of the circle, π is a constant (approximately equal to 3.14), and r is the radius of the circle (which is half the diameter).

In this case, the diameter is 22 feet, so the radius is:

r = d/2 = 22/2 = 11 feet

Now we can calculate the area of the circle:

A = πr^2 = 3.14 x 11^2 = 379.94 square feet (rounded to 2 decimal places)

To cover this area with sand, we need to know how many bags of sand are required. We are told that one bag of sand covers about 4 square feet, so we can calculate the number of bags of sand required as follows:

Number of bags = Area of pool / Area covered by one bag

Number of bags = 379.94 square feet / 4 square feet per bag

Number of bags ≈ 95 bags

Since we need to round up to a whole number of bags, we will need at least 96 bags of sand to cover the base of the circular pool.

The man's daily wage is obtained applying the proportions in the context of the problem.

Their wages per hour are in the ratio 7:5, hence the man's hourly wage is 7/5 of the woman's hourly wage, hence:

7/5 x 24/8 = 7/5 x 3 = 21/5 = $4.2 per hour.

The man works 10 hours a day, hence the daily wage is given as follows:

Answer: To find the monthly payment for each option, we can use the following formula:

Monthly Payment = Total Cost * (Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Months))

For the option to finance at the store for 2 years at 14% interest:

Total Cost = $2,000

Monthly Interest Rate = 14% / 12 = 0.011667

Number of Months = 2 years x 12 months/year = 24 months

Substituting these values into the formula, we get:

Monthly Payment = $2,000 * 0.011667 / (1 - (1 + 0.011667)^(-24)) = $95.13

Therefore, the monthly payment for financing at the store for 2 years at 14% interest is $95.13.

For the option to use his credit card at 21% interest for 1 year:

Total Cost = $2,000

Monthly Interest Rate = 21% / 12 = 0.0175

Number of Months = 1 year x 12 months/year = 12 months

Substituting these values into the formula, we get:

Monthly Payment = $2,000 * 0.0175 / (1 - (1 + 0.0175)^(-12)) = $185.44

Therefore, the monthly payment for using his credit card at 21% interest for 1 year is $185.44.

To find the total repayment for each option, we can multiply the monthly payment by the number of months:

For the option to finance at the store for 2 years at 14% interest:

Total Repayment = $95.13/month x 24 months = $2,283.12

Therefore, the total repayment for financing at the store for 2 years at 14% interest is $2,283.12.

For the option to use his credit card at 21% interest for 1 year:

Total Repayment = $185.44/month x 12 months = $2,225.28

Therefore, the total repayment for using his credit card at 21% interest for 1 year is $2,225.28.

The value of x from the trapezium is 118° and the value of y from the trapezium is 35°.

What is a trapezium?

A trapezium is a quadrilateral with two parallel sides. It has two non-parallel sides that are called the legs of the trapezium, and the other two sides are called the bases.

From the given trapezium 4 angles are x, y, 62° and 145°.

Here, x+62°=180° (Sum of allied angles is 180°)

x=180°-62°

x=118°

Now, y+145°=180°

y=180°-145°

y=35°

The required solutions of the equation |3x| = 9 are x = 3 and x = -3.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Here,

We can solve the given equation by isolating the absolute value on one side and simplifying it.

|3x| = 9
| x | = 3

Now, we need to solve two separate equations for x:

When x is positive:
|x| = 3
=> x = 3 (since x is positive)

When x is negative:
|x| = 3
-x = 3 (since x is negative)
x = -3

a) The family's best deal is with Smokey's BBG which charges $780 for 60 guests.

b) Choosing Smokey's BBG over Bennie's BBQ will save (difference) the family $40.

The total cost for each company's catering services is worked out using their cost functions.

Smokey's BBG does not charge a fixed cost, unlike Bennie's BBG.

The difference between the total costs of the companies is obtained by subtraction.

The number of guests = 60

                                  Smokey's BBQ       Bennie's BBQ

Catering Fees                       $0                        $100

Charge per person              $13                          $12

The total charge for 60    $780 ($13 x 60)     $820 ($100 + $12 x 60)

Difference between the charges = $40 ($820 - $780)

However, using a system of equations we can determine the number of guests that makes the total cost the same for each company as 100.

Thus, comparing the total costs for the two companies shows the difference or cost savings to be gained by the family.

Answer: The correct answer is yes, he brought enough money to get into the park.

Step-by-step explanation:

Well, let's analyze the information provided:

Admission to the amusement park for 8 students is $ 100. If each student agreed to share of cost equally, it means that we must divide those 100, for each of those students.

Therefore it will remain 100/8 = 12.5

If each student must pay 12.5, and Noah brought $ 13, that means he will have enough money to enter the park, and he will even have $ 0.50 left over.

Step-by-step explanation:

Given the cubic f(x) = x³ -x² -5x -3 has x=3 as a root, you want the other roots.

You can find the quadratic factor of the polynomial using synthetic division. That tells you ...

  f(x) = (x -3)(x² +2x +1)

You recognize the quadratic factor as the perfect square trinomial ...

  x² +2x +1 = (x +1)²

The remaining roots will be the values of x that make these factors zero:

  x +1 = 0   ⇒   x = -1 . . . . . and the other is the same: multiplicity 2

None of the given angles are complementary angles.

An angle is a geometric figure formed by two rays with a common endpoint called the vertex. The rays are also known as the sides or legs of the angle. Angles are usually measured in degrees or radians and are used to measure the amount of rotation between two lines or planes.

The sum of two angles is 90 degrees if and only if they are complementary angles.

Using this concept, we can add up the angles in pairs to see which ones are complementary:

Angle AFB + Angle BFC = 40 + 60 = 100 degrees (not complementary)

Angle BFC + Angle CFD = 60 + 50 = 110 degrees (not complementary)

Angle CFD + Angle DFE = 50 + 30 = 80 degrees (not complementary)

To find the average number of pages written per hour, we need to divide the total number of pages written by the total time taken:

Total pages written = 6 3/10 = 63/10

Total time taken = 2 1/3 = 7/3

Average pages written per hour = Total pages written / Total time taken
