Answer:

area =  2348 ft^2

Step-by-step explanation:

(15 x 40) + (28x40) + Pi(20^2)(0.5) = area

area = 600 + 1120 + 628 = 2348 ft^2

Answer:

Step-by-step explanation:

So we have a half circle, a rectangle, and a triangle.

circle area is A=3.14r^2 and the radius is 40/2=20, since we only have half a circle

A=3.14(20^2)/2=628ft^2

The rectangle has an area A=LW=28(40)=1120ft^2

The triangle has area A=bh/2=40(15)/2=300ft^2

So the total area is

A=628+1120+300=2048ft^2

Answer:

9.6

Step-by-step explanation:

Find the diagram attached. Using the similarity theorem of triangles

AC/AD = FH/EH

Given

AC = 24

AD = 35

FH = x

EH = 14

Substitute into the formula

24/35 = x/14

Cross multiply

35×x = 24×14

35x = 336

x = 336/35

x = 9.6

Hence the value of x is 9.6

divide both sides by 5

t=-3.7

Answer:

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

Answer:

Dividing by fractions is just like multiplying fractions, except for one additional step. To divide any number by a fraction: First step: Find the reciprocal of the fraction. Second step: Multiply the number by the reciprocal of the fraction. Third step: Simplify the resulting fraction if possible.

Answer:

X = 3

Step-by-step explanation:

First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.

5x + 2 = 17

Then Solve For X

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide by 5

X = 3

Check your answer

5(3) +2 = 17

15 + 2 = 17

17 = 17

It is correct!

The linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)

The linear factors of polynomials are the first-degree equations that act as the building block for the simple or complex higher-order polynomials.

Given that, a polynomial 2x⁴+13³+27x²+13x-15, the remainder upon division with x²+4x +5 is zero,

That means, x²+4x +5 is a factor of the given polynomial,

On diving 2x⁴+13³+27x²+13x-15 by x²+4x +5 we get 2x²+5x+3 as quotient that means,  x²+4x +5 and 2x²+5x+3 are the factors of the polynomial,

On factorizing both the factors we get,

(2x+3)(x+1)(x+2+i)(x+2-i)

Hence, the linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)

mean= 0.65

standard deviation=[tex]\sqrt{\frac{0.65(0.35)}{100}[/tex]

Step-by-step explanation:

The mean of the sampling distribution is 0.65 and the standard deviation is approximately 0.004779.

The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.

The mean of the sampling distribution of the proportion of citizens who are registered to vote is equal to the proportion of all citizens who are registered to vote, which is 65% = 0.65.

The standard deviation of the sampling distribution is equal to the standard error of the proportion, which can be calculated as follows:

standard error = √((65% × 35%) / 100)

= √((0.65 × 0.35) / 100)

= √(0.0227 / 100)

= √(0.0000227)

= 0.004779

Therefore, the standard deviation is approximately 0.004779.

Answer:

The missing side's length is 18.2

Step-by-step explanation: To find a missing side in a right triangle, you use the Pythagorean theorem to solve it. According to the Pythagorean Theorem, [tex]12.6^{2}[/tex] + [tex]13.1^2[/tex] = [tex]x^{2}[/tex], so 158.76 + 171.61 = [tex]x^{2}[/tex] ⇒ 330.37 = [tex]x^{2}[/tex] ⇒ x ≈ 18.2.

Answer/Step-by-step explanation:

1. The figure is composed of a triangle and a rectangle.

Area of the triangle = ½*base*height

base = 4 ft

height = 12 - 8 = 4ft

Area of triangle = ½*4*4 = 8 ft²

Area of rectangle = length * width

Length = 8 ft

Width = 4 ft

Area of rectangle = 8*4 = 32 ft²

✔️Area of the figure = 8 + 32 = 40 ft²

2. The figure is composed of a semicircle and a triangle

Area of the semicircle = ½(πr²)

radius (r) = 3 cm

π = 3

Area = ½(3*3²) = 13.5 cm²

Area of triangle = ½*base*height

base = 3*2 = 6 cm

height = 6 cm

Area = ½*6*6 = 6 cm²

✔️Area of the figure = 13.5 + 6 = 19.5 cm²

Answer:

The perimeter of the square is 76ft.
