Answer:

1A: The area of a flat, or plane figure is the number of unit squares that can be contained within it. The unit square is usually some standard unit, like a square meter, a square foot, or a square inch.

1B: A radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length

1C: A diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.

2A: A=wl

2B: A=πr to the power of 2

Step-by-step explanation:

1. Area = the measurement of the surface of a 2D shape.

Radius = a straight line from the center of a circle to its circumference.

Diameter = a straight line from one side of a circle to the other side, passing through the center point.

2. The area of a rectangle is found by multiplying the length by the width.

The area of a circle is found by multiplying the radius squared by PI.

3. Find the area of the paper and the area of the game pieces, then divide the area of the paper by the area of the game piece.

Answer:

x≥-6

Step-by-step explanation:

The domain is every value of x.  Since the function does not include any values of x less than -6, x≥-6 is the domain.

The inequality which represents the domain of the function is y>=6 . Hence, option A is correct.

Answer:

2320 calories

Step-by-step explanation:

We are given the following information;

Carol;

8 slices of pizza

5 containers of skim milk

5 cups of fruit salad

Chick;

5 slices pf pizza

7 containers of skim milk

7 containers of fruit salad

We let x denote the calories in each slice of pizza and y the calories in each cup or container of fruit salad. Chicks calorie count can thus be represented by the following expression;

5x + 7(40) + 7y

5x + 7y + 280

We are also informed that chicks calorie count was 2500 and thus the following equation is formed;

5x + 7y + 280 = 2500

5x + 7y =2220. This will be our first equation

On the other hand, Carols calorie count can be represented by the following expression;

8x + 5(40) + 5y

8x + 5y + 200

We are also informed that Carols calorie count was 3070 and thus the following equation is formed;

8x + 5y + 200 = 3070

8x + 5y = 2870. This will be our second equation

Now, we have two sets of equation;

5x + 7y =2220

8x + 5y = 2870

We solve these simultaneously to determine the values of x and y;

We multiply the first equation by 8 and the second by 5 in order to eliminate x and solve for y;

40x + 56y = 17760

40x + 25y = 14350

Subtracting the second equation from the first yields;

31y = 3410

y = 110

We substitute this value in the first equation and solve for x;

5x + 7(110) = 2220

5x = 2220 - 770

5x = 1450

x = 290

Therefore, each slice of pizza contains 290 calories. Carol had 8 slices of pizza implying that her total calories count from pizza was;

8 * 290 = 2320 calories

You can make 10 combinations.

Step-by-step explanation:

you can make 10 combinations because all you have to do is just add all the numbers then you get 10

We want to find the total number of combinations of outfits, given that we know the number of each type of clothes that you have.

Using basic counting, we will get that there are 30 different outfit combinations.

Let's see how to get that:

To count the total number of combinations, the first thing we need to find is the selections.

Here we have 3 selections:

Now we need to find the number of options for each one of these selections:

To get the total number of combinations, we just need to multiply all of these numbers of options, we will get:

3*2*5 = 30

This means that there are 30 different outfit combinations.

Answer:

D

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 6, - 8), thus

(x + 6)² + (y + 8)² = r²

The radius is the distance from the centre to a point on the circle

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)

r = [tex]\sqrt{(0+6)^2+(0+8)^2}[/tex] = [tex]\sqrt{36+64}[/tex] = [tex]\sqrt{100}[/tex] = 10

Hence

(x + 6)² + (y + 8)² = 100 → D

Answer:

(5,6)

Step-by-step explanation:

just answered a similar question for you a while ago so I have updated by response to match the different values:

the midpoint formula is

(x1 + x2/2) , (y1 + y2/2) <-- both the x1 and y1 coordinates also are divided by 2

so to solve for the midpoint, we take our endpoints and plug it into the formula

we will list the coordinates as the following to plug it into the formula:

x coordinate 1 = 2

x coordinate 2 = 8

y coordinate 1 = 4

y coordinate 2 = 8

substituting these values into the formula we get this:

x =(2 + 8/2) , y = (4 + 8/2)

x = 2 + 8 = 10/2 = 5 which is our x coordinate for the midpoint

y = 4 + 8 = 12/2 = 6 which is our y coordinate for the midpoint

in an ordered pair it would be (5, 6)

Final answer:

The midpoint of the segment with the endpoints (2,4) and (8,8) is (5, 6).

Explanation:

The midpoint of a line segment is the point that is equidistant from both endpoints. To find the midpoint of a segment with endpoints (2,4) and (8,8), we can use the midpoint formula.

The midpoint formula is given by:

M = (x1 + x2)/2, (y1 + y2)/2

Using the given endpoints, we substitute the values into the formula:

M = (2 + 8)/2, (4 + 8)/2 = (10/2, 12/2) = (5, 6)

Therefore, the midpoint of the segment with the given endpoints is (5, 6).

The volume of cone v= 113.04 cm³.

Step-by-step explanation:

Formula used to find volume of cone is:

[tex]v= \pi * r^2 * \frac{h}{3}[/tex]

where r is the radius and h is the height of cone.

In the given question we are given:

height h= 6 cm

diameter d= 6 cm

We know radius r = d/2 = 6/2 = 3 cm

There are different ways percent problems can be solved. One of the ways to solve a percent problem is by using proportion method.

By using proportion method, the set-up is the same, I.e.

[tex]\frac{Part}{whole}[/tex] = [tex]\frac{percentage}{100}[/tex]

In any given expression:

What number is 80% of 10?

It can be expressed as:

[tex]\frac{part}{10}[/tex] = [tex]\frac{80}{100}[/tex]

If we cross multiply, then we have:

10 x 80 = 100 x part

800 = 100 x part

[tex]\frac{800}{100}[/tex] = [tex]\frac{100}{100}[/tex] x part (800 cross out 100 to give 8 and 100 cross out 100)

8 = part

3 is what percentage of 6?

It can be expressed as:  

[tex]\frac{3}{6}[/tex] = [tex]\frac{percentage}{100}[/tex]

If we cross multiply, then we have:

3 x 100 = 6 x the percent

300 = 6 x the percent

[tex]\frac{300}{6}[/tex] = [tex]\frac{6}{6}[/tex] x the percent (300 cross out 6 to give 50 and 6 cross out 6)

50 = the percent

KEYWORDS:

The proportion method is a way to solve percentage problems by setting up a proportion between the part and the whole.

The proportion method is a way to solve percentage problems. To use this method, you need to set up a proportion between the part and the whole.

For example, if you have a class with 35 students and 13 of them are wearing sandals, you can find the percentage of students wearing sandals by setting up the proportion: 13/35 = x/100. Then, you cross multiply and divide: 13 * 100 = 35 * x. Solve for x to find the percentage: x = 37%.

For this case we make a rule of three to find the cost of dairy products and vegetables.

$ 140 --------------> 1

x ------------------>[tex]\frac {1} {7}[/tex]

Where "x" represents the amount of money spent on dairy products.

[tex]x = \frac {\frac {1} {7} * 140} {1}\\x = 20[/tex]

So, I spend $ 20 on dairy products.

Now we have:

$ 140 --------------> 1

y ------------------> [tex]\frac {3} {20}[/tex]

Where "y" represents the amount of money spent on vegetables.

[tex]x = \frac {\frac {3} {20} * 140} {1}\\x = 21[/tex]

So, I spend $ 21 on vegetables.

Therefore, I spend $ 41 on vegetables and dairy products.

$ 140- $ 41 = $ 99

Spending $ 99 dollars on products other than vegetables and dairy products
