Answer 1

Answer:

Answer/Step-by-step explanation:

Problem 1:

E is the centroid of the triangle.

Centroid theorem states that the centroid is ⅔ of the distance of each vertex to the midpoint of the side opposite each vertex.

This implies that:

AE = ⅔(AD)

AE = 21

Therefore:

21 = ⅔(AD)

3*21 = 2(AD)

(3*21)/2 = AD

31.5 = AD

AD = 31.5

Problem 2: Apply the centroid theorem. Thus:

DE = ⅓(AD)

DE = 12

Therefore,

12 = ⅓(AD)

12*3 = AD

36 = AD

AD = 36

Answers

the quotient of a number k and 5 means to divide k by 5.k / 5We will put this is quotes for clarity.(k / 5)the number b less than means to subtract be from (k / 5), so the answer is:(k / 5) - b

If €1 = £0.72 what would is the exchange rate £ - €

Answers

We know that 1 euro equals 0.72 pounds. To deduce the inverse conversion, we have to manipulate this equation so that it looks like

"x euros = 1 pound"

If you divide both sides of the equation by 0.72, the pounds coefficient will become 1, and you'll get the amount of euros that equal 1 pound.

The vertices of a square are listed below.Q(0,0), U(0,4), A(4,4), D(4,0)

After the square undergoes an isometric transformation, its new vertices are Q'(0,0), U'(4,0), A'(4,-4), and D'(0,-4). Which of the following options best describes the type of transformation that maps QUAD onto Q'U'A'D'?

a. reflection
b. translation
c. rotation

Answers

The right answer for the question that is being asked and shown above is that: "a. reflection." After the square undergoes an isometric transformation, its new vertices are Q'(0,0), U'(4,0), A'(4,-4), and D'(0,-4). The option that best describes the type of transformation that maps QUAD onto Q'U'A'D' is that a. reflection

Luke puts $500 into a savings account that earns 6% simple interest each year. How much money will be in the account after 3 years

Answers

9514 1404 393

Answer:

$590

Step-by-step explanation:

The account balance is given by ...

A = P(1 +rt) . . . . simple interest rate r for t years

A = $500(1 +0.06×3) = $590

There will be $590 in the account after 3 years.

Answer:

= $90

Step-by-step explanation:

I = prt

I = 500 x 0.06 x 3

I = $90

Use the table below to answer the following question.2. Do the values in the table represent a linear function? If so, what is the function rule?
(1 point)
The values do not show a linear function.
Yes, the values show a linear function: y = x + 4.
Yes, the values show a linear function: y = 2x + 2.
Yes, the values show a linear function: y = 2x.

Answers

The values in the table do represent a linear function.

Y = 2X

Plug in values from the table

-4 = 2(-2)

-4 = -4
