I Need Help With This Question.

Answers

Answer 1

Step-by-step explanation:

the volume of a cylinder is as for any regular shaped object

ground area × height

here the ground area is a circle, so we get

pi×r²×h

with r being the radius (half the diameter), and h the height.

therefore,

pi×(2.7/2)²×10 = 3.14×1.8225×10 = 57.25552611... cm³

so, the first option is correct.

The hexagon surface area is the amount of space on it

The surface area of the hexagon is 665.11 square centimeters

How to determine the surface area?

The question is incomplete, as the diagram is not given.

So, I will calculate the surface area of the hexagon.

The side length of the hexagon is given as:

L = 16 km

The surface area of the hexagon is calculated using:

A = 1.5[tex]\sqrt3[/tex]L^2

This gives

A = 1.5 * [tex]\sqrt3[/tex] * 16^2

Evaluate the product

A = 665.11

Hence, the surface area of the hexagon is 665.11 square centimeters

x² - 7x+10=0

Answers

Answer:

x²-7x+10=0
x²-5x-2x+10=0
x(x-5)-2(x-5)=0
(x-2)(x-5)=0 ANS!

Step-by-step explanation:

First we will multiply x² into 10, the answer will be 10x². Now, take L.C.M of 10, the L.C.M will be 5x2 or 2x5. Now we will make sure that:
2x x 5x=10x² while 5x+2x=7x. Now, we know that 7x is in negative so, we will change the signs and it will become x²-5x-2x+10=0. Now take common:
x(x-5)-2(x-5)=0. Now, write the common taken numbers first and then the other brackets in last i.e: (x-2)(x-5)=0

Find the area of each circle with the given radius or diameter. Use 3.14 for pi.

Answers

Answer: (Note*: Radius is half of the diameter, so the d = 2 and d = 12 have been converted into radius's instead to solve the problem).

r^2 = 4 in: 50.24 in^2.

r^2 = 2 in: 12.56 in^2.

d = 2 or r^2 = 1 in: 3.14 in^2.

r^2 = 8 in: 200.96 in^2.

d = 12 or r^2 = 6 in: 113.04 in^2.

Step-by-step explanation: To find the area of a circle, you need the radius squared times pi, which is 3.14.  The following is solved below:

4^2 x 3.14 = 50.24 in^2.

2^2 x 3.14 = 12.56 in^2.

1^2 x 3.14 = 3.14 in^2.

8^2 x 3.14 = 200.96 in^2.

6^2 x 3.14 = 113.04 in^2.

Therefore, the following above are the answers you need.

Let me know if this is right! :)

Answer:

r = 4.)  50.24

r = 2.) 12.56

d = 2.) 3.14

r = 8.) 200.96

d = 12.) 113.04

Step-by-step explanation:

The formula for finding the area of a circle would be π(pi) x r (radius)²

1.) r = 4

4 x 4 = 16

16 x 3.14 = 50.24

2.) r = 2

2 x 2 = 4

4 x 3.14 = 12.56

3.) d = 2

2 ÷ 2 = 1

1 x 1 = 1

1 x 3.14 = 3.14

4.) r = 8

8 x 8 = 64

64 x 3.14 = 200.96

5.) d = 12

12 ÷ 2 = 6

6 x 6 = 36

36 x 3.14 = 113.04

Milk is on sale for 40% off when it is normally $3.75 per gallon. How much will a gallon of milk cost?

The discounted price for milk is $_____(Round to the nearest cent.)

Answers

Answer:

$2.25 is the discounted price for each gallon.

Step-by-step explanation:

So you take 40% and convert it into decimal form, which is 0.4. Then you take $3.75 x 0.4 = 1.5. Then subtract $1.50 from $3.75, and that equals $2.25 each gallon.

In the triangle shown, the ratio of the height to the length of the base is 3:4.


Chose True or False on A-C.


A. The area of the triangle is twice the area of a parallelogram with the same base and height


B. The height is 3/4 the base length.


C. The area is 8.64 mm²

Answers

Answer:

A. False

B. True

C. True

Step-by-step explanation:

A: Area of traingle = 1/2 × Base Length × Height

Area of parallelogram = Base Length × Height

Therefore, Statement A is False.

B: Base on the ratio for height to base length 3:4,

Statement B is True.

C: Base Length = 4.8 ÷ 4 × 3

= 3.6 mm

Area of Triangle = 1/2 × Base Length × Height

= 1/2 × 3.6 × 4.8

= 8.64mm²

Therefore, Statement B is True.

What is the area of the circle with the equation 2x2 + 2y2 = 8?

Answers

Answer:

4pi

Step-by-step explanation:

Divide through by two to get

x^2 + y^2 = 4       4 = radius squared     radius = 2

area = pi r^2 = 4 pi

Answer: 4π

Step-by-step explanation:

Under the assumption that those are exponents, and your equation is:

[tex]2x^2+2y^2=8[/tex]

You first must turn this circle equation into standard form. The standard form for the equation of a circle is as follows:

[tex](x-a)^2+(y-b)^2=r^2[/tex]

For your case, the constants 'a' and 'b' are clearly zero. We have an annoying coefficient of 2 which can be cancelled by dividing both sides by 2:

[tex]x^2+y^2=4[/tex]

If you'd like, we can write this in the following way:

[tex](x-0)^2+(y-0)^2=2^2[/tex]

So, our circle is centered at the origin (0, 0) and has a radius of 2 units. The area of a circle is given by the formula:

[tex]A=\pi r^2[/tex]

[tex]A=\pi (2^2)=4\pi[/tex]

What is a Polynomial?

A polynomial can be defined as an algebraic expression that consists of constants, variables, and positive exponents.

The degree of a polynomial is dependent on the highest exponent value carried by any of the terms. Also, the number of terms a polynomial has determines what type of polynomial it is.

Given the polynomial, - 2r + 6r^5 + sr:

It has three terms, therefore, it is a trinomial.

find the x and y intercepts of the linear equation 2x - 4y = -20

Answers

Answer:

see explanation↓

Step-by-step explanation:

We are given the following equation of a line:

[tex]2x-4y=-20[/tex]

To determine the x-intercept we must set "y = 0":

[tex]2x-4(0)=-20[/tex]

[tex]2x=-20[/tex]

Now, we divide both sides by 2:

[tex]x=-\frac{20}{2}=-10[/tex]

Therefore, the "x" intercept is -10.

To determine the y-intercept we set "x = 0":

[tex]2(0)-4y=-20[/tex]

[tex]-4y=-20[/tex]

Now, we divide both sides by -4:

[tex]y=\frac{-20}{-4}=5[/tex]

Therefore the y-intercept is 5.

Find the exact circumference of a circle with a diameter of 5 inches.

The circumference is
inches.

Answers

Answer:

15.7 in

Step-by-step explanation:

You can use the below formula to find the circumference of the circle.

C = π × d

Here,

d ⇒ diameter ⇒ 5 in

Let us find it now.

C = π d

C = 3.14 × 5

C = 15.7 in

Answer:

The exact diameter is 15.707963267948966192313216916398 inches multiplied by full form of pi.

________________________________________________________

Solve

Set C as your substitute for circumference.

[tex]C =[/tex]

Now that we have this, we need to assign a value of pi long form followed by the diameter, which is 5 inches².

[tex]C = \pi d[/tex]

[tex]d = 5[/tex]

Lastly, ignore C, and multiply pi by the diameter, d.

[tex]\pi * d = 15.707963267948966192313216916398[/tex] without rounding

Which choice describes an equation
that has a solution set of
"All real numbers"?
3(x + 1) = 3x + 3

Answers

Answer:

Step-by-step explanation:

Remark

Choose any number at all and see what happens.

Suppose x = 8

3*(8 + 1) = 3*8 + 3

3(9) = 27

3*8 + 3 = 24 + 3 = 27

What you have shown is that the second choice is incorrect. There is at least one value that makes the equation correct (that is, both sides come to the same result.)

If choice two is false then choice one must be true since these results may give the only 2 possible results.

25% of z is 150. Find the value of z.
(Can y’all show your work on this so I know how you got it)

Answers

The answer is 600
25 x 4 =100
150 x 4 = 600
checking work
.25 x 600= 150

Answer:

z = 600

Step-by-step explanation:

Method 1 - ratios

If 150 is 25% then z is 100%:

[tex]\begin{aligned} 150 : 25 & = z : 100\\\dfrac{150}{25} & = \dfrac{z}{100}\\150 \cdot 100 & = 25z\\15000 & = 25z\\z & = \dfrac{15000}{25}\\z & = 600 \end{aligned}[/tex]

Method 2

Calculate the amount for 1%, then multiply by 100% to find z:

25% = 150

⇒ 1% = 150 ÷ 25 = 6

⇒ z = 100% = 6 x 100 = 600
