The measure of the segment CD is 12 and CE is 8.

In a triangle, the centroid is the point of intersection of the three medians, which are line segments joining each vertex to the midpoint of the opposite side.

The centroid divides each median into two segments, with the distance from the centroid to the vertex being twice the distance from the centroid to the midpoint of the opposite side.

Let M be the midpoint of side AB, N be the midpoint of side AC, and P be the midpoint of side BC. Then, we have:

CD = 2DP

CE = 2DN

We are also given that DE = 15. Since D is the centroid, we have:

AD = BD = CD/3

AE = CE/3

DC + DP = PC

CE + DN = NE

AD + AE = DE

Using these relationships, we can find CD and CE:

CD = 2DP = 2(PC - DC) = 2((AD + DP) - (AD/3)) = 2(2AD/3) = 4AD/3

CE = 2DN = 2(NE - CE) = 2((AE + DN) - (AE/3)) = 2(2AE/3) = 4AE/3

To find AD and AE, we can use the fact that AD + AE = DE and AD = BD:

AD + BD = DE

AD + (2AD/3) = 15

5AD/3 = 15

AD = 9

AE = DE - AD = 15 - 9 = 6

Substituting these values into the equations for CD and CE, we get:

CD = 4AD/3 = 4(9)/3 = 12

CE = 4AE/3 = 4(6)/3 = 8

Therefore, CD = 12 and CE = 8.

The required area of tortilla is 16π square inches.

What is an area of a circle?

Area of a circle is defined as the region occupied by the circle in two-dimensional plane.

Mathematically,

                         A = π (d/2)²

where d is the diameter of circle

or,                      A = π r²  

where r is the radius of circle.

Now, given diameter of tortilla is 8inches.

⇒ d  = 8inches

Since,tortilla is a circle

So, area of tortilla A = π (d/2)²

⇒ A = π (8/2)²

⇒ A = π (4)²

⇒ A = 16π square inches

Hence, required tortilla's area is 16π square inches.

Answer:

x = 30

y = 115

Step-by-step explanation:

Suppose line m is parallel to line n:

65+y = 180 because they are supplementary angles

subtract 65 from both sides

y = 115

angle represented by y and the angle represented by 3x + 25 are alternate angles and their measure is equal, so to find the value of x we can write the following equation:

3x + 25 = 115 subtract 25 from both sides

3x = 90 divide both sides by 3

x = 30

Given: Radius of the wheel = 30 inches, Revolutions per minute = 401 rpmThe linear speed of the car in miles per hour can be calculated as follows:

Step 1: Convert the radius from inches to miles by multiplying it by 1/63360 (1 mile = 63360 inches).30 inches × 1/63360 miles/inch = 0.0004734848 milesStep 2: Calculate the distance traveled in one minute by the wheel using the circumference formula.Circumference = 2πr = 2 × π × 30 inches = 188.496 inchesDistance traveled in one minute = 188.496 inches/rev × 401 rev/min = 75507.696 inches/minStep 3: Convert the distance traveled in one minute from inches to miles by multiplying by 1/63360.75507.696 inches/min × 1/63360 miles/inch = 1.18786732 miles/minStep

The radius of the wheel on a car is 30 inches. If the wheel is revolving at 401 revolutions per minute, The linear speed of the car is approximately 19.2 miles per hour.

To find the linear speed of the car in miles per hour, we need to calculate the distance traveled in one minute and then convert it to miles per hour. Here's how we can do it step by step:

Calculate the circumference of the wheel:

The circumference of a circle is given by the formula

C = 2πr

where r is the radius of the wheel.

In this case, the radius is 30 inches, so the circumference is

C = 2π(30)

   = 60π inches.

Calculate the distance traveled in one revolution:

Since the circumference represents the distance traveled in one revolution, the distance traveled in inches per revolution is 60π inches.

Calculate the distance traveled in one minute:

Multiply the distance traveled in one revolution by the number of revolutions per minute.

In this case, it is 60π inches/rev * 401 rev/min = 24060π inches/min.

Convert the distance to miles per hour:

There are 12 inches in a foot, 5280 feet in a mile, and 60 minutes in an hour.

Divide the distance traveled in inches per minute by (12 * 5280) to convert it to miles per hour.

The final calculation is (24060π inches/min) / (12 * 5280) = (401π/66) miles/hour.

Approximating π to 3.14, the linear speed of the car is approximately (401 * 3.14 / 66) miles per hour, which is approximately 19.2 miles per hour.

When the coefficient on an independent variable becomes statistically significant after controlling for something, it means that the variable's effect on the dependent variable is considered significant and reliable, even when accounting for the influence of the controlled variable.

Controlling for something typically involves adding additional independent variables to a statistical model to examine their individual effects on the dependent variable while holding other variables constant. By doing so, we can assess the unique contribution of each variable and determine if the coefficient on the initially non-significant variable becomes significant when accounting for other factors.

If the coefficient on an independent variable becomes statistically significant after controlling for another variable, it suggests that the initially non-significant variable has an impact on the dependent variable that was previously masked or confounded by the presence of the controlled variable. This highlights the importance of considering multiple factors simultaneously to obtain a more accurate understanding of the relationship between variables.

Option C

Step-by-step explanation:

We know that the expression:

2*w^2 + 10*w

Represents the area of a rectangle with width w.

Now we want to find the situation that can be represented with the expression:

100 - 10*w - 2*w^2

Let's rewrite this as:

100 - (2*w^2 + 10*w)

Then we are subtracting the area of our rectangle to an area of measure 100.

Now, suppose that we have a square of 10in by 10 in.

The area of that square will be:

A = 10in*10in = 100 in^2

Now if we cut our rectangle (with an area = 2*w^2 + 10*w) from that square, the new area of the figure will be:

area = 100in^2 - (2*w^2 + 10*w)

Which is exactly the expression in the question, then the correct option is:

Option C

The child who received more land if the land was divided evenly among them compared to the way the mother divided it is Sofia. Option (d) is correct.

A mother divided her land of 141/4 acres among her 5 adopted adult children such that Samuel received 11 acres, Sophia received 9 acres, Anthony received 8 acres, Jasmine received 5 acres, and Juan received 4 1/4 acres.

Among the given children, the child who received more land if the land was divided evenly among them compared to the way the mother divided it is Sofia.

To determine the land received by each child if the land was divided evenly among them, divide the total area by the number of children.

Therefore, each child would receive 141/4 ÷ 5 acres.

141/4 ÷ 5 = 113/20 ≈ 5.65 acres.

(to two decimal places)

Approximately, each child would receive 5.65 acres of land.

Which is not how the mother divided her land among the children.

Now, let's compare the area of land that each child received with the 5.65 acres they would have received if the land was divided evenly among them.Samuel received 11 acres.

11 > 5.65

So, Samuel received more land than they would have received if the land was divided evenly among them.Sophia received 9 acres.

9 < 5.65

So, Sophia received less land than they would have received if the land was divided evenly among them.

Anthony received 8 acres.

8 < 5.65

So,

Anthony received less land than they would have received if the land was divided evenly among them.

Jasmine received 5 acres.

5 = 5.65

So, Jasmine received the same land as they would have received if the land was divided evenly among them.

Juan received 4 1/4 acres.

21/4 = 5.25 and

5.25 < 5.65

So, Juan received less land than they would have received if the land was divided evenly among them.
