The volume of a football with a diameter of 22 centimeters is approximately 1795.76 cubic centimeters

To determine the volume of a football, we can use the formula for the volume of a sphere:

V = (4/3)πr³

Given that the football has a diameter of 22 centimeters, we can find the radius (r) by dividing the diameter by 2:

r = 22 cm / 2 = 11 cm

Now we can substitute the value of the radius into the volume formula:

V = (4/3)π(11 cm)³

Calculating this expression, we have:

V = (4/3)π(11 cm)³

 = (4/3)(3.14159)(11 cm)³

 ≈ 1795.76 cm³

Therefore, the volume of the football is approximately 1795.76 cubic centimeters (cm³).

On using subtraction it can be seen that Simone needs more 8 inches space in her room to fit the chest beside the bed. So, the chest cannot fit in Simone's room with the measurements of room = 100 inches and bed  = 74 inches.

What is subtraction?

The process of subtracting one number from another is called subtraction. The way to calculate the difference between two numbers is by using the basic arithmetic operation of subtraction, which is represented by the symbol (-).

The measurement for Simone's room is, a = 100 inches.

The measurement for Simone's bed is, b = 74 inches.

The amount of space left in Simone's room = a - b.

Using the arithmetic operation of subtraction -

= 100 - 74

= 26

Hence, 26 inches of space is left in Simone's room.

The measurement for chest that Simone wants to fit in her room next to bed is 85 centimeters.

To convert 85 cm to inches divide the length by 2.5 -

Using the arithmetic operation of division -

85/2.5 = 34

Hence, the measurement of the chest in inches is 34 inches.

26 < 34

Using the arithmetic operation of subtraction -

34 - 26 = 8

So, Simone has 26 inches space left and the size of chest is 34 inches, which cannot be fitted in the room.

Therefore, Simone cannot fit the chest in her room.

Using proportions, the costs are given as follows:

a) Total Labor Cost: $2,505,600.

b) Total Product Cost: $1,950,000.

c) Total Cost = $4,455,600.

d) Cost per home = $461.77.

e) Cost per week = $99,013.33.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For item a, the labor cost is found using the earnings of the workers, as follows:

45 weeks x 5 days x 8 hours x 58 per hour x (12 + 8 + 4 workers)

Hence:

Total Labor Cost = 45 x 5 x 8 x 58 x 24 = $2,505,600.

For item b, the product cost is the cost of the boards, hence:

(175 + 150 + 50 boards) x 5,200

Total Product Cost = 375 x 5,200 = $1,950,000.

For item c, the total cost is the sum of the product cost and the labor cost, hence:

Total Cost = 2,505,600 + 1,950,000 = $4,455,600.

For item d, the cost per home is found dividing the total cost by the 9,649 homes, hence:

Cost per home = 4455600/9649 = $461.77.

For item e, the cost per week is found dividing the total cost by the 45 weeks, hence:

Cost per week = 4455600/45 = $99,013.33.

The factors of the equation is  (x - 5)  (x + 2).

Given the equation is x²-3x-10

we are asked to factorize the equation.

Factorization is the process of identifying two or more expressions whose product is an algebraic expression. It is often referred to as finding the factors of an expression. Finding two or more expressions whose product is the given expression—known as factorization—is the process of breaking down algebraic expressions. A factor is any number that divides the given number by itself without leaving any remainder. It simply implies representing a number as the product of two other integers.

x²-3x-10

x² - 5x + 2x - 10

x(x - 5) + 2(x - 5)

(x - 5)  (x + 2)

Thus, the factorization of the given expression  x²-3x-10

= (x - 5)  (x + 2)

The number of nickels and dimes are 11 and 15 respectively.

What are system of equations?

A system of equation is set of 2 or more equation in 2 or more variables. These equations can be solved by using the methods like substitution and elimination.

Let the number of nickels be x and number of dimes is y.

We are given the total number of nickels and dimes are 26.

hence the equation becomes x + y = 26               (1)

Total amount by nickels and dimes is $2.05

1 nickel equals 5 cents that is $0.05

and 1 dime is 10 cents that is $0.1

Hence the equation becomes

0.05x + 0.1y = 2.05                                   (2)

Multiply equation 2 by 10 we get

0.5x + y = 20.5             (3)

Subtract equation 1 and 3 we get

0.5x = 5.5

multiplying both sides by 2 we get

x = 11

Now subtract this value in equation 1 we get

x + y= 26

11 +y =26

y= 15

Answer:

C. y=1/2x+2

Step-by-step explanation:

1. Find the slope using the slope formula.

Slope formula: y2-y1/x2-x1

Let the y-value in the second ordered pair (4,4) be y2, and the 3 in the first ordered pair (2,3) be y1. 4 and 2 from these ordered pairs will be x2 and x1.

Plug these values into the equation and simplify.

4-3/4-2

=1/2

Slope is 1/2

2. Choose one of the ordered pairs and plug those numbers and the slope into the point-slope formula.

Point slope formula: y-y1=m(x-x1). M represents the slope, and the x1 and y1 represent the values of the ordered pair.

Let's use the pair (4,4).

y-4=1/2(x-4)

3. Simplify the equation to convert to y=mx+b format.

Multiply the inside of the parentheses by 1/2.

y-4=1/2x-2

Add 4 to both sides.

y=1/2x+2

A function \(P(t) = 170.(1.30)^t\)  that gives the deer population P(t) on the reservation t years from now

We were told there were 170 stags on reservation. The number of deer is increasing at a rate of 30% per year.

We could see the deer population grow exponentially since each year there will be 30% more than last year.

Since we know that an exponential growth function is in form:

\(f(x) = a*(1+r)^x\)

where a= initial value, r= growth rate in decimal form.

It is given that a= 170 and r= 30%.    

Let us convert our given growth rate in decimal form.

\(30 percent = \frac{30}{100} = 0.30\)

Upon substituting our given values in exponential function form we will get,

    \(P(t) = 170.(1+0.30)^t\)

⇒ \(P(t)= 170.(1.30)^t\)

Therefore, the function \(P(t) = 170.(1.30)^t\) will give the deer population P(t) on the reservation t years from now.

The number of  children bought meal tickets =  700

The number of adult  bought meal tickets = 950

A linear equation is one that can be written as display style a 1x 1+ldots +a nx n+b=0, where x 1, ldots, x n are the variables and display style b, a 1, ldots, a n are the coefficients, which are frequently real integers.

Let x and y be the quantity of kid and adult tickets sold, respectively. 1650 tickets were sold in total, as far as we know.

x + y = 1650

x = 1650 - y

At $12 for adults and $4 for children, the total revenue from tickets is $14200. There are

4x + 12y = 14200

substituting the value of x in the equation:

4(1650 - y) + 12y = 14200

6600 - 4y + 12y = 14200

6600 + 8y = 14200

8y = 14200 - 6600 = 7600

y = 7600 / 8

= 950 adult tickets

x = 1650 - 950

= 700 children tickets

Answer:

a₉ = 11

Step-by-step explanation:

Substitute n = 9 into the nth term formula, that is

a₉ = 3(9) - 16 = 27 - 16 = 11

The combined present worth of the costs associated with the proposed bridge design, including construction and annual operating costs, is $10,583,333.

To calculate the combined present worth of costs, we need to consider the construction cost and the annual operating cost over the infinite life of the bridge. We will use the concept of present worth, which is the equivalent value of future costs in today's dollars.

The present worth of the construction cost is simply the initial cost itself, which is $9,000,000. This cost is already in present value terms.

For the annual operating cost, we need to calculate the present worth of perpetuity. A perpetuity is a series of equal payments that continue indefinitely. In this case, the annual operating cost of $700,000 represents an equal payment.

To calculate the present worth of the perpetuity, we can use the formula PW = A / MARR,

where PW is the present worth, A is the annual payment, and MARR is the minimum attractive rate of return (also known as the discount rate). Here, the MARR is given as 12%.

Plugging in the values, we have PW = $700,000 / 0.12 = $5,833,333.

Adding the present worth of the construction cost and the present worth of the perpetuity, we get $9,000,000 + $5,833,333 = $14,833,333.

However, since we are looking for the combined present worth, we need to subtract the salvage value, which is zero in this case. Therefore, the combined present worth of the costs associated with the proposed bridge design is $14,833,333 - $4,250,000 = $10,583,333, rounded to the nearest dollar.

If x₁₁ increases by one unit while keeping the other predictor variables constant, the response variable y₁ will increase by B₁ units. In the given multiple regression model, SST is equal to 500.

In the multiple regression model, the effect of increasing one unit of a predictor variable on the response variable depends on the specific coefficient (B) associated with that predictor variable.

The sign and magnitude of the coefficient determine the direction and extent of the effect.

For the given model y₁ = B₁ + B₁x₁₁ + ... + Bx + u, if x₁₁ increases by one unit while keeping the other predictor variables constant, the response variable y₁ will increase by B₁ units, assuming all other coefficients and the error term remain constant.

Regarding the second question, you mentioned the regression model as y = B₁ + B₁x₁ + B₂x₂ + Bₓ + u, and provided the values:

SSR = 100 and SSE = 400.
