The circle below has a sector 120° shaded. 120° 22. Then area of sector is 200.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Area of sector=theta/360*πr^2

Given π = 7,

theta=120 degrees

d=22, so r=11.

Area of sector=210/360*7*7^2

=0.583*7*7*7

=200.08

Therefore area of sector is 200.

The time taken by Franklin to make a 200 sq. foot cement patio = 14 hours

The time taken by Scott to make a 200 sq. foot cement patio = 10 hours.

Let x be the number of hours it would take Franklin and Scott to make the patio together.

Then x = 14 x 10 / (14 + 10)

⇒ 1 / x = (14+10)/(14 x 10)

⇒ 1/x = 1/14 +1/10

This is the equation to find the number of hours taken by Franklin and Scott together.

Step-by-step explanation:

The midpoint of AR is (1/2 , 1).

Let the points be:

A(0,0) = (x₁,y₁)

B(1,2) = (x₂,y₂)

Midpoint = (x₁₊x₂/2) , (y₁₊y₂/2)

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway. In addition, the halfway is reached if a line is drawn to divide the line that connects these two places.

= (0₊1/2) , (0₊2/2)

=(1/2 , 2/2)

= (1/2 , 1)

hence the midpoint of the number line is  (1/2 , 1).

The volume of the square pyramid that has a side length of 7 and a height of 21 is calculated as: 343 units³.

A square pyramid is a type of pyramid that has a square base and four triangular faces.

The volume of a square pyramid can be calculated using the formula expressed as:

Volume (V) = 1/3(a²)(h), where a is the length of a side and h is the height of the square pyramid.

Given:

Side length (a) = 7 units

Height of the square pyramid = 21 units

Substitute

Volume (V) = 1/3(7²)(21)

Volume (V) = 1/3(49)(21)

Volume (V) = 1(49)(7)

Volume = 343 units³

The numerical expression using commutative property of multiplication that is equivalent to 2⁸ is 2² x 2² x 2² x 2² = 256.

Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division. The result of a multiplication operation is called a product.

Now the given exponent is,

2⁸

Now, 8 can be written as using associative property of addition,

8 = 2 + 2 + 2 + 2

Thus we can write,

2⁸ = 2^( 2 + 2 + 2 + 2 )

Using exponential property

x^(a + b) = x^a . x^b

Thus we get,

2⁸ = 2^2 . 2^2 . 2^2 . 2^2

Thus numerical expression for 2^8 = 2^2 . 2^2 . 2^2 . 2^2

Solving we get,

2^8 = 4 x 4 x 4 x 4 = 256

Thus, the numerical expression using exponential property of multiplication that is equivalent to 2⁸ is 2² x 2² x 2² x 2² = 256.

The bank can borrow $6440 based on the $7000 deposit.

The following deposit amount: $7000

Because the reserve rate is 8%, the bank will reserve 8% of the 7000. The remaining funds can be lent by the bank.

7000 × (8/100) = amount set aside

= $560

Thus, the reserve deposit is $560.

Amount the bank is willing to lend = 7000 - 560 = $6440

Answer: P = 4x + 2, A = x² + x - 6

Step-by-step explanation:

       Perimeter is the distance around a shape, or all the sides added together. We will create an equation, plug in the known values, and then solve. The first step is to distribute, then we combine like terms.

   P = 2l + 2w

   P = 2(x + 3) + 2(x - 2)

   P = 2x + 6 + 2x - 4

   P = 4x + 2

       The area of a rectangle is found by multiplying the width by the length. We will use the FOIL method.

A = (x + 3)(x - 2)

A = x² + x - 6

First ➜ x * x = x²

Outside ➜ x * -2 = -2x

Inside ➜ 3 * x = 3x

Last ➜ 3 * -2 = -6

Add together ➜ x² + 3x - 2x - 6 = x² + x - 6
