Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

y = -2x

Step-by-step explanation:

the line passes through the origin (where both x and y are 0...they both meet).

that rules out it being the X +4 and x - 4 options.

the line goes from top left to bottom right, indicating that the gradient is negative. the gradient value if the number of front of the x in the equation.

negative gradient is a minus sign.

so our answer is y = -2x

Answer:

  (b)  10π square centimeters

Step-by-step explanation:

You want the total surface area of a cylinder 1 1/4 cm in radius and 2 3/4 cm in height.

The surface area is given by the formula ...

  A = 2πr(r +h)

Filling in the given dimensions, we find the surface area to be ...

  A = 2π(1 1/4)(1 1/4 +2 3/4) = 5/2π(4) = 10π . . . . cm²

Answer:

The chances are 1/6 because 6-8 is 1/6 of the possible timings.

:)

Answer:

7/8

Step-by-step explanation:

Because it is 8 hours combined (noon to 8) 8 will be the denominator and since it is 3 hours (6 to 8) 3 is the numerator. Keep that aside.

Since there are 2 days in a weekend 2 will be the denominator and since it is on Sunday 1 will be the numerator.

So 3/8 + 1/2 = 7/8

Answer:a

Step-by-step explanation:

The solution to the equation ax² + bx + c = 0 , has a graph that crosses the y-axis once and does not intersect the x-axis, then the equation has one real root and two complex conjugate roots that lie on either side of the axis of symmetry.

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

If the graph of the equation ax² + bx + c = 0 crosses the y-axis once, it means that the equation has one real root. This is because when x = 0, the equation becomes:

c = 0² + 0 + c = c

Therefore, the point (0, c) is on the y-axis, which means the graph crosses the y-axis once.

If the graph does not intersect the x-axis, it means that the discriminant b² - 4ac is negative. This is because the discriminant determines the nature of the roots of a quadratic equation, and when it is negative, the roots are complex (not real) and the graph does not intersect the x-axis.

So, the solution(s) of the equation ax² + bx + c = 0 are:

x = (-b ± √(b² - 4ac)) / 2a

Since the discriminant is negative, the term inside the square root is negative, and there are no real solutions for x. Instead, the solutions are complex conjugates of the form:

x = (-b ± i√(4ac - b²)) / 2a

where i is the imaginary unit. Since the real part of these solutions is -b/2a, which is the axis of symmetry of the parabola, and the parabola does not intersect the x-axis, the complex roots will be a conjugate pair that lie on either side of the axis of symmetry.

Hence , the quadratic equation is solved

Step-by-step explanation:

Answer:

\(13.5 m^{2}\)

Step-by-step explanation:

area = length × width

       = 15m  × 9/10m

       = 15m  ×  0.9m

       = \(13.5 m^{2}\)

Answer:

\(\Huge \fbox{Area = 13.5 m^{2}$}\)

Step-by-step explanation:

To find the area of the baseboard, we need to multiply the length by the width:

To multiply these values, we can convert the width to a decimal by dividing the numerator (9) by the denominator (10):

Now we can multiply the length and width:

Therefore, the area of the baseboard is 13.5 m².

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Formula used,

Area of rhombus = Base × height

Substituting the values,

\( \longrightarrow\)Area = 18 × 15.5

\( \longrightarrow\) Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
\(A=bh\)

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

A=279 cm²

Answer:

-18.75 + 7.5x

Step-by-step explanation:

-2.5(7.5 - 3x)

you can seperate it into

-2.5 * 7.5 and -2.5 * -3x

-2.5 * 7.5 = - 18.75

-2.5 * -3x = 7.5x

so... -2.5(7.5 - 3x) = -18.75 + 7.5x

Answer: -14

Step-by-step explanation:

Plug in the x and y value. 8(-1/4)-3^2-3

-2-9-3=-14

Answer:

-14

Step-by-step explanation:

Let's simplify it, because if we do, we can find the value and then deduce whether it is divisible by 60.

2^10 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2

2^10 = 1,024

2^8 = 256

2^5 = 32

2^3 = 8

Substitute the expressions in the equation for their values...

(1,024+256)(32-8)

Simplify...

(1,280)(24)

Simplify...

30,720

Now, divide it by 60...

512 * 60 = 30,720

512*60=(2^10+2^8)(2^5-2^3)

Answer:

B) Square root of 45 and C) Square root of 30, are both irrational numbers, because they aren't perfect squares.

Explanation:

A square root can be defined as, "a factor of a number that, when multiplied by itself, gives the original number."

For example: 8 squared (8^2) is the same as 8 × 8 , which equals 64 , so the square root of 64 is 8. Since 64 is a perfect square, then it makes it a rational number.

Hope this makes sense to ya :)
