The center of the circle that can be circumscribed about Triangle EFG with E(2,2), F(2,-2), and G(6,-2) is (2, -2).

To find the center of the circle circumscribed about triangle EFG, we can first find the midpoint of EF and the midpoint of FG.

These midpoints will lie on the perpendicular bisectors of EF and FG respectively.

The intersection of these bisectors will give us the center of the circle. Let's calculate it step-by-step:

Step 1: Find the midpoint of EF.

Midpoint of EF = ((2+2)/2, (2-2)/2) = (2, 0).

Step 2: Find the midpoint of FG.

Midpoint of FG = ((2+6)/2, (-2-2)/2) = (4, -2).

Step 3: Find the equation of the perpendicular bisector of EF.

The slope of EF = (0 - 2)/(2 - 2) = undefined. The midpoint of EF is (2, 0).

Hence, the equation of the perpendicular bisector of EF is x = 2.

Step 4: Find the equation of the perpendicular bisector of FG.

The slope of FG = (-2 - (-2))/(6 - 2) = 0. The midpoint of FG is (4, -2).

Hence, the equation of the perpendicular bisector of FG is y = -2.

Step 5: Solve the equations of the perpendicular bisectors to find the center of the circle. Since x = 2 and y = -2, the center of the circle is (2, -2).

Final answer:

To find the center of the circle that can be circumscribed about Triangle EFG, use the midpoint formula and equations of the perpendicular bisectors.

Explanation:

To find the center of the circle that can be circumscribed about Triangle EFG with coordinates E(2, 2), F(2, -2), and G(6,-2), we can use the following steps:

Find the midpoint of each side of the triangle, which will be the center of the circle.

Use the midpoint formula to find the coordinates of the midpoints of EF and FG.

The center of the circle will be the point where the perpendicular bisectors of each side intersect.

Find the equation of the perpendicular bisectors of EF and FG.

Solve the system of equations formed by the equations of the perpendicular bisectors to find the coordinates of the center of the circle.

The center of the circle that can be circumscribed about Triangle EFG is (-2/3, -4/3).

Answer: 86

Step-by-step explanation: You would add up all the numbers, then divide by the amount of numbers there are.

For example

79+89+90=258

Since there are three numbers(79,89,90) you would divide 258 by 3 and would get 86.

Answer:

The correct answer option is 'then'.

Step-by-step explanation:

The "to prove" part of the information is the 'then' of the "if-then" statement.

For example, we have this problem:

[tex] y = 2 x - 1 [/tex]

If [tex] x = 3 [/tex], then find the value of y.

Here in this problem, we are asked that 'if' the value of x is true then prove it by substituting in the value.

Answer:

The answer is Then.

Step-by-step explanation:

The "to prove" part of the information is the THEN of the "if-then" statement.

If is the question like, it is not validated. You are asking something if it holds true.

For example: If it rains heavily, then water bodies fill up.

So, here you are proving that water bodies fill if rains are heavy.

Final answer:

The correct equation is c=3.5h+15, where c is the total rental cost and h is the number of hours the kayak is rented. The equation includes a fixed fee of $15 and a variable hourly rate of $3.50. The correct answer is option (A).

Explanation:

The equation representing the function for the total cost c, to rent a kayak for h hours, is A. c=3.5h+15. This equation consists of a fixed cost and a variable cost.

The fixed cost, or y-intercept, is the initial $15 fee required to rent the kayak, which is represented when h=0. The variable cost, or slope, is $3.50 per hour of rental, indicating that for each additional hour h, the cost increases by this amount.

ANSWER

The height is 6 units.

The base is 2 units.

EXPLANATION

The given rectangle has vertices (–4, 7), (–2, 7), (–2, 1), and (–4, 1).

To find the height of the rectangle, we use the points (-2,7) and (-2,1) or

(-4,7) and (-4,1) because they form the vertical side of the rectangle.

The height is

[tex]|7-1|=6 units[/tex]

To find the base, use the points (-2,7) and (-4,7) or (-2,1) and (-4,1).

The base is

[tex]|-2--4|=2 units[/tex]

Answer: The base is 2 units and the height is 6 units.

Step-by-step explanation:

You can plot the points  (-4, 7), (-2, 7), (-2, 1), and (-4, 1) and obtain the rectangle shown in the figure attached.

As you can see in the figure, the distance between the points of the base is:

[tex]d=\sqrt{(-2-(-4))^2+(1-1)^2}\\d=2[/tex]

Then the lenght of the base is 2 units

The distance between the points of the height is:

 [tex]d=\sqrt{(-2-(-2))^2+(1-7)^2}\\d=6[/tex]

Then the height is 6 units

52 cups.

3.35 times 52 equals 174.20

2.45 times 77 equals 188.60

So 52 cups of apple cider were sold in total.

Answer:

 The number of cups of apple cider sold was 60 cups

Step-by-step explanation:

We will develop equations to solve this problem.

Let a= price for a cup of apple cider in dollars

Let b= price for a donut in dollars

Let x = number for cups of apple cider sold

Let y= number of donuts sold

Let z = number of items sold on the day = 126 items

Let v = total money made = $362.70

Lets write two equations. One in terms of the amount of items sold of cups of apple cider and donuts, and one in terms of how much money was made for selling cups of apple cider and donuts.

z = x + y

x = z- y (1)

v = ax + by (2)

we substitute equation 1 in to equation 2

v = a(z-y) +by = az -ay +by = az +y(b-a)

solve for y

y = (v-az)/(b-a) = (362.70 - 3.35×126)/(2.45-3.35) = 66 donuts were sold

therefore x = z-y = 126-66 = 60 cups of apple cider were sold

Answer:

588.827

Step-by-step explanation:

Volume of a cylinder

[tex]\pi \times {r}^{2} \times h[/tex]

larger cylinder: r=2, h=28

volume of larger cylinder lets say (V) :

[tex]\pi \times {2}^{2} \times28 \\ = 4 \times 28\pi =112\pi[/tex]

vokume of smaller cylinder lets say (v): r=2, h=7

so in ratio terms the

Ans: 4:1

The ratio of the volume of the larger cylinder to the smaller cylinder is 4:1, calculated using the volume formula for cylinders, V = πr²h.

To calculate the ratio of the volumes of two cylinders, we need to use the formula for the volume of a cylinder, V = (πh), where r is the radius and h is the height.

For the first cylinder with a height of 7 cm and a radius of 2 cm, the volume is V₁ = 3.14 (2 cm) (7 cm) = 88.36 cm³.

For the second cylinder with a height of 28 cm and the same radius, the volume is V₂ = 3.14 (2 cm) (28 cm) = 353.44 cm³.

The ratio of V2 to V1 is then 353.44 cm³ / 88.36 cm³, which simplifies to 4:1.

Answer:

20 girls.

Step-by-step explanation:

The girl to boy ratio is 10 to 2.

Insert the multiplier m and write an equation for the total number of students:

10 m + 2 m = 24, or

12 m = 24.  Then m = 2.

The number of girls is 10(m) = 10 m = 10(2) = 20.

The number of boys is 2(m) = 4

Note that 20 (girls) + 4 (boys) = 24 (students), as specified.

Note that 20/4 = 10/2, which is the given ratio.
