Probably too late, but still need to know how to do this.

Formula for the area of a circle: A = πr²     [pi times radius(r) squared]

The radius is half of the diameter. [diameter would be a line that would go through the whole circle, the radius would be a line that would stop/end halfway through the circle - see attached image]

They gave you the diameter, which is 3, so divide it by 2 or multiply by 1/2 to get the radius, which will be 1.5.

A = πr²    Plug in 1.5 for r

A = π(1.5)²         Find 1.5²  [or 1.5 x 1.5 = 2.25]

A = 2.25π meters²

Final answer:

In the equation f(-11)=5x+1, solving for x yields x = -2.4.

Explanation:

To find what x equals in the function f(-11)=5x+1, we start by understanding that the function f(x) identifies the relation between x and f(x). In this case, f(-11) has been given the value of 5x+1. Therefore, we solve for x by setting the expression equal to f(-11).

We have the equation 5x + 1 = f(-11). Since f(-11) is given as a constant, we substitute and solve for x:

5x = -12

x = -2.4

Hence, x equals -2.4 in the function f(-11)=5x+1.

Answer:

Marcos had 6 nickel coins and 9 quarter coins.

Step-by-step explanation:

We are given the following in the question:

Let x be the number of nickel coins and y be the number of quarter coins.

Marcos had 15 coins in nickels and quarters.

Thus, we can write the equation:

[tex]x + y =15[/tex]

He had 3 more quarters than nickels. We can write he equation,

[tex]y = x + 3[/tex]

Solving the two equations, we get,

[tex]2y = 18\\y = 9\\x + 9 = 15\\x = 6[/tex]

Thus, Marcos had 6 nickel coins and 9 quarter coins.

The solution to the system of equations representing Marcos's coins is x = 6 and y = 9. Hence, Marcos had 6 nickels and 9 quarters.

This question pertains to creating and solving a system of equations in mathematics. Given Marcos had 15 coins in nickels and quarters and considering the information that he had 3 more quarters than nickels, two equations can be formed from this. The first equation sets up the total number of coins: x + y = 15. The second equation sets ups the difference in quantity of each coin: y = x + 3.

To find the solution, substitute the second equation in for y in the first equation. This gives: x + (x + 3) = 15. Solve the equation and find x = 6. Furthermore, using x in our second equation, we get y = 6 + 3 = 9. Therefore, Marcos had 6 nickels and 9 quarters.

To determine the maximum number of adults and children that can attend the play without exceeding the bus capacity of 40 people and the $400 budget, set up and solve a system of equations representing the capacity and budget constraints. The solution is 8 adults and 32 children.

Explanation:

We are given a situation where a company charges $18 for each adult (a) and $8 for each child (c) for a bus trip to an upcoming play, with the constraints that the bus holds a maximum of 40 people and the available budget is $400. To find the maximum number of adults and children that can attend under these constraints, we need to set up a system of equations:

For the capacity constraint: a + c = 40

For the budget constraint: 18a + 8c = 400

We can solve this system using substitution or elimination. Let's use elimination. Multiply the first equation by -8 and add it to the second equation to eliminate c:

-8a - 8c = -320

18a + 8c = 400

Adding these two equations together gives us:

10a = 80

Thus, a = 8. Plugging a = 8 back into the first equation, we get c = 32.

The maximum number of adults and children that can attend the play is 8 adults and 32 children.

Answer:

110°

Step-by-step explanation:

the supplement of an angle is 30 degrees less than twice the measure of the angle itself. find the angle and its supplement.

Let the angle be A, then its supplement = (180 - A)

Now, since the supplement is 30 degrees less than twice the measure of the angle itself, then we'll have:

180 - A = 2A - 30

-3A = - 210

A, or the angle = [tex]\frac{-210}{-3}[/tex]= 70 °

Its supplement, (180 - A) = 180 - 70 = 110°

Answer:

16 feet.

Step-by-step explanation:

Given:

Ben’s living room is a rectangle measuring 10 yards x 168.

Question asked:

How many feet does the legs of the room exceed the width ?

Solution:

By applying unitary method:

Length of rectangle = 10 yards = 30 feet (1 yard = 3 feet)

                                                                    (10 yard = [tex]3\times10 = 30)[/tex]

Breadth of  rectangle = 168 inch = 14 feet   (12 inch = 1 feet)

                                                                       (1 inch = [tex]\frac{1}{12}[/tex])

                                                                       ( 168 inch = [tex]\frac{1}{12}[/tex][tex]\times168 = 14 feet)[/tex]

By subtracting the breadth from the length of rectangle,

30 feet - 14 feet = 16 feet

Therefore,  by 16 feet, length of the room exceed the width.

Answer:

a. Number of people surveyed were 900.

b. 360 people preferred running.

Step-by-step explanation:

Given:

On a recent survey, 60% of those surveyed indicated that they preferred walking to running.

If 540 people preferred walking.

Now, to find a. number of people were surveyed. b. number of people preferred running.

a.

Number of people preferred walking = 540.

Percentage of people preferred walking = 60%.

Let the total number of people surveyed be [tex]x.[/tex]

Now, to get the number of people surveyed:

60% of x = 540.

[tex]\frac{60}{100} \times x=540[/tex]

[tex]0.60\times x=540[/tex]

[tex]0.60x=540[/tex]

Dividing both sides by 0.60 we get:

[tex]x=900.[/tex]

Thus, number of people surveyed = 900.

b.

Total number of people surveyed = 900.

People preferred walking = 540.

Now, to get the people preferred running we subtract people preferred walking from total number of people surveyed:

[tex]900-540[/tex]

[tex]=360.[/tex]

Thus, people preferred running = 360.

Therefore, a. Number of people surveyed were 900.

b. 360 people preferred running.

Surface area of the three dimensional figure is 166 unit².

Solution:

Let us find the area of the net of the figure.

Length = 7, Width = 5, Height = 4

Area of the bottom = length × width

                                = 7 × 5

                                = 35 unit²

Area of the Top =  length × width

                          = 7 × 5

                          = 35 unit²

Area of the left = width × height

                         = 5 × 4

                         = 20 unit²

Area of the right = width × height

                         = 5 × 4

                         = 20 unit²

Area of the front = length × height

                            = 7 × 4

                            = 28 unit²

Area of the back = length × height

                            = 7 × 4

                            = 28 unit²

Surface area = 35 + 35 + 20 + 20 + 28 + 28

                     = 166 unit²

Surface area of the three dimensional figure is 166 unit².

Final answer:

The constant of proportionality for the given ratios is 1.5, as each second number in the ratio is 1.5 times the corresponding first number.

Explanation:

To find the constant of proportionality for the given set of ratios, we first look at each pair to determine if there is a common constant that each first number is multiplied by to result in the second number. Inspecting the given ratios (2, 3), (4, 6), (6, 9), and (8, 12), we can see that in each case, the second number is 1.5 times the first number.

For example, for the ratio (2, 3), if you multiply 2 by 1.5, you get 3. Similarly, for the ratio (4, 6), multiplying 4 by 1.5 gives you 6, and so on. This consistency across the ratios confirms that the constant of proportionality is 1.5.
