Answer: the perimeter is 40.1 feet

The area is 76 ft²

Step-by-step explanation:

The given shape contains a rectangle and a trapezoid.

The perimeter of a shape is the distance around the shape. Therefore, the perimeter of the given shape is

4 + 8 + 4 + 4.5 + 14 + 5.6 = 40.1 ft

The area of the rectangle is

8 × 4 = 32ft²

The formula for determining the area of a trapezoid is

Area = 1/2(a + b)h

Where a and b are the length of the opposite sides.

h represents the vertical height.

Area = 1/2(14 + 8)4

= 1/2 × 22 × 4 = 44ft²

Area of the shape is

32 + 44 = 76 ft²

Answer:

Perimeter = 40.1 ft.

Area = 76 ft^2.

Step-by-step explanation:

The perimeter is the sum of the exterior sides.

The perimeter = 4 + 8 + 4 + 4.5 + 14 + 5.6

= 40.1.

The area = the area of rectangle + area of the trapezoid

= 8 * 4 + (8 + 14) * 4 / 2

= 32 + 44

= 76.

Missing term = –2xy

Solution:

Let us first find the quotient of $-8x^2y^3 \div xy$ .

$-8x^2y^3 \div xy=\frac{-8x^2y^3 }{xy}$

$=\frac{-8\times x\times x\times y\times y\times y}{xy}$

Taking common term xy outside in the numerator.

$=\frac{xy(-8\times x\times y\times y)}{xy}$

Both xy in the numerator and denominator are cancelled.

$=-8xy^2$

Thus, the quotient of $-8x^2y^3 \div xy$ is $-8xy^2$ .

Given the quotient of $-8x^2y^3 \div xy$ is same as the product of 4xy and ____.

$-8xy^2=4xy$ × missing term

Divide both sides by 4xy, we get

⇒ missing term = $\frac{-8xy^2}{4xy}$

Cancel the common terms in both numerator and denominator.

⇒ missing term = –2xy

Hence the missing term of the product is –2xy.

Mashutka [201]

Answer:

Diameter = 23 Radius = 11.5

Step-by-step explanation:

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

diameter = 23

Divide the diameter by 2.

There you go, you found the circle's radius
