Answer:

140 ft

Step-by-step explanation:

Given data

Area= 14 square feet

Height a = 1/5 ft

Base b=????

We know that the area of a triangle is given as

Area= (1/2)B*H

substitute

14= 1/2* B* 1/5

14= B/10

cross multiply

B= 140

Hence the base is 140 ft

Answer: 18 1/2 inches

Step-by-step explanation:

Applying the segments of chords theorem, the diameter of the original plate is: PR = 18 ⅛ inches.

Based on the segments of chords theorem, the following equation is true:

(AQ)(QB) = (PQ)(QR)

Plug in the values

(9)(9) = (8)(QR)

QR = 81/8

QR = 10 ⅛ inches.

Diameter PR = QR + PQ

Diameter PR = 10 ⅛ + 8

Diameter PR = 18 ⅛

Answer:

1296 sq inches

Step-by-step explanation:

To start, you need to get the total area of each individual roll of wrapping paper. To do this, you need to multiply the length x width, which would be 18 x 24 = 432. Then, you have three rolls so you mutiply that by three, which is 432 x 3 = 1296. You add the unit, and that leaves you with 1296 sq inches.

Given

[tex]AD = 3x + 7[/tex]

[tex]BC = 5x - 9[/tex]

Required

Find

If AD parallel to BC, then:

[tex]AD = BC[/tex]

This gives:

[tex]3x + 7 = 5x - 9[/tex]

Collect like terms

[tex]3x- 5x = -7-9[/tex]

[tex]-2x = -16[/tex]

Solve for x

[tex]x = 8[/tex]

Substitute [tex]x = 8[/tex] in [tex]AD = 3x + 7[/tex]

[tex]AD = 3 * 8 + 7[/tex]

[tex]AD = 31[/tex]

Answer:

1. It is doubled

I can't help with paragraph explanation as it is something that you should write

2. The change in the area is that is 16 times more

No explanation as it is something that you should write

3. The change in area is that it is 9 times less

I can't help with paragraph explanation as it is something that you should write

Step-by-step explanation:

20 + 16 = 36

40 + 32 = 72

72/36 = 2

Hence it is doubled

(5 x 6) / 2 = 15

(20 x 24) / 2 = 240

240/15 = 16

It is 16 times more

15 x 21 = 315

5 x 7 .= 35

315/35 = 9

Answer:

Step-by-step explanation:

2x=x(1.07)^t

2=(1.07)^t

t=log2/(log 1.07) ≈10.2 4 years

so it doubles in approximately in  10.2 years

To solve the problem we must know about Compounding.

Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.

It is given by the formula,

[tex]A = P(1+r)^t[/tex]

where A is the value after t period of time,

P is the value of the asset at the beginning, and,

r is the rate of interest.

The value of the home doubles once each decade.

Given to us

As it is given that the value of a home increases by 7% each year, therefore, the value of the home is compounding every year.

We know the formula of compounding,

[tex]A = P(1+r)^t[/tex]

Now, let's assume a house whose value is 'P' today, therefore, substitute the value of the house in the formula of compounding,

[tex]A = P(1+r)^t[/tex]

Substitute the rate at which the value is increasing,

[tex]A = P(1+0.07)^t[/tex]

We know that in a decade there are 10 years,

[tex]A = P(1.07)^{10}[/tex]

[tex]A = 1.967P\approx 2P[/tex]

As we can see that the value of the home is almost 2 times the 'P' therefore, twice the value of the home at the beginning.

Hence, the value of the home doubles once each decade.

Step-by-step explanation:

Since we have the endpoints of the diameter, the midpoint coordinates of the line segment joining them gives the centre of the circle.

That is, centre (a,b) = ( [1+(-3)]/2, [4+2]/2) = (-1,3)

Distance between the given points give the diameter and half of that is the radius length.

So, radius r = (1/2)* sqrt ( [1-(-3)]^2 + [4–2]^2) = sqrt(5)

Thus equation required is: (x-a)^2 + (y-b)^2 = r^2

So, (x+1)^2 + (y-3)^2 = 5

The equation of the circle is (x + 1)² + (y - 3)² = 5

The endpoints of the diameter are given as:

(1, 4) and (−3, 2)

Start by calculating the midpoint using:

Midpoint = 0.5 * (x₁ + x₂, y₁ + y₂)

So, we have:

Midpoint = 0.5 * (1 - 3, 4 + 2)

Evaluate

Midpoint = (-1, 3)

So, the center (a,b) of the circle is:

(a,b) = (-1,3)

Calculate the length of the diameter using:

D² =(x₁ - x₂)² + (y₁ - y₂)²

This gives

D² = (1 + 3)² + (4 - 2)²

D² = 20

Take the square roots

D = 2√5

Divide by 2 to calculate the radius

r = √5

Square both sides

r² = 5

The equation of the circle is then represented as:

(x - a)² + (y - b)² = r²

This gives

(x + 1)² + (y - 3)² = 5

Hence, the equation of the circle is (x + 1)² + (y - 3)² = 5
