Answer:

80%

Step-by-step explanation:

We can get the percent value of the amount of students who have older siblings by diving 28 by 35.

28 / 35 = 0.8

We can convert this decimal into a percentage, giving us 80%.

Therefore, we know that 80% of the students in Ms. Bailey's class have siblings.

Answer:

11.8

Step-by-step explanation:

5 + 10 + 12 + 4 + 6 + 11 + 13 + 51= 118

The average (mean) is equal to the sum of all the data values divided by the count of values in the data set.

Count = 10

Sum = 118

Average = Sum / Count

118/10= 11.8

The given object is made up of circle and squares. The expression for the area of the flower garden is 4π²(9π - 4)square units

The given object is made up of circle and squares. To find the area of the garden, we wil use the expression

Area of the garden = area of circle - area of square

Find the area of circle

Area = πr²

Area = π(6π)²

Area pf circle = 36π³ square units

For the square

A = length * length

A = 4²π²

A = 16π²square units

Take the difference

D =   36π³ - 16π²

D =4π²(9π - 4)square units

Hence the expression for the area of the flower garden is 4π²(9π - 4)square units

Answer: (pi * r^2) - (6x*4x)

Step-by-step explanation:
Since the formula of the area of a circle is pi * r^2 and the area of a square is base* height or in this case 6x*4x the answer is: (pi * r^2) - (6x*4x). The reason we subtract is because your trying to find the area of the square inside the circle.

Answer:

A = $17,238.65

I (interest) = $8,838.65

Step-by-step explanation:

Using the formula A = P(1 + r/n)^nt

A = $17,238.65

A = P + I where

P (principal) = $8,400.00

I (interest) = $8,838.65

First, convert R as a percent to r as a decimal

r = R/100

r = 3.6/100

r = 0.036 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 8,400.00(1 + 0.036/12)^(12)(20)

A = 8,400.00(1 + 0.003)^(240)

A = $17,238.65

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $8,400.00 at a rate of 3.6% per year compounded 12 times per year over 20 years is $17,238.65

Two different roots the given polynomial function have. Therefore, option C is the correct answer.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The given equation is y=(x-2)(x+3)

The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.

Here, (x-2)(x+3)=0

(x-2)=0 and (x+3)=0

x=2 and x=-3

Therefore, option C is the correct answer.

Add 3y to both sides

6x-3y- 15 + 3y =0+3y

Simplify

6x- 15 =3y

Add 15 to both sides

6x-15 + 15 =3y + 15

The volume of the solid generated by revolving the plane region y=3−x about the y-axis is 9π cubic units.

It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.

We have a function:

y = 3 - x

From the graph:

Shell radius = y

Height = 3 - y

From the shell method, we can write the integral as follows:

[tex]\rm Volume =2\pi\int\limits^0_{-3} {y(3-y)} \, dy[/tex]

[tex]\rm Volume =2\pi\int\limits^0_{-3} {(3y-y^2)} \, dy[/tex]

After solving the above definite integral, we will get volume:

Volume = 9π cubic units

Thus, the volume of the solid generated by revolving the plane region y=3−x about the y-axis is 9π cubic units.

Answer:

Step-by-step explanation:

The number that indicates the extent of a region on a plane or a curved surface is known as area. The total surface area of this triangular prism is 1,782 cm².

The number that indicates the extent of a region on a plane or a curved surface is known as area. The area of a plane region or plane area refers to the area of a form or planar lamina, whereas the area of an open surface or the border of a three-dimensional object is referred to as surface area.

The given figure has two rectangles and two triangles, therefore, the total surface area can be written as,

[tex]\rm Total\ Surface\ Area =\text{Surface area of rectangle1} + \text{Surface area of rectangle2} + (2 \times \text{Surface area of triangle})\\[/tex]

Substitute the dimensions we will get,

[tex]\rm Total\ Surface\ Area =( 25 \times 30)+ (24 \times 25) + (2 \times \dfrac12 \times 18 \times 24)[/tex]

                              [tex]\rm = 750+600+432\\\\=1,782\ cm^2[/tex]
