George and mindy are playing with a ball that has a diameter of 38 centimeters. What is the volume of the ball?

Answers

Answer 1

Answer:

28734.6cm^3

Step-by-step explanation:

Given data

diameter of ball = 38cm

radius = 38/2 =  19cm

The volume of a spher= 4/3πr^3

substitute

V= 4/3*3.142*19^3

V=4/3*3.142*6859

V=4/3*21550.978

V=86203.912/3

V= 28734.6cm^3

Hence the volume of the ball is 28734.6cm^3

a cone has a height of 4 ft and a volume of 7.77 Ft cubed determine its radius to the nearest tenth of a foot​

Answers

Answer:

The radius of the cone is approximately 1.4 feet

Step-by-step explanation:

The given parameters of the cone are;

The height of the cone, h = 4 ft.

The volume of the cone, V = 7.77 ft.³

The volume, 'V', of a cone is given by the following formula;

V = 1/3 × π·r²·h

Where;

V = The volume of the cone = 7.77 ft.³

r = The radius of the cone

h = The height of the cone = 4 ft.

By substituting the vales of 'h' and 'V' in the above equation, we have;

7.77 ft.³ = 1/3 × π × r² × 4 ft.

∴ r = √(3 × 7.77 ft.³/(π × 4 ft.)) = 1.36196580784 ft.

∴ The radius of the cone, r ≈ 1.4 ft. (rounding the answer to the nearest 10th)

Answers

Answer:

They have different slopes but the same y-intercept, so they have one solution.

Step-by-step explanation:

Both equations are organized in slope-intercept form, y=mx+b. m is the slope and b is the y-intercept.

In the first equation, the slope is 1/2 and the y-intercept is -3.

In the second equation, the slope is -1/2 and the y-intercept is -3.

These two equations have different slopes, in fact, the second equation has the same slope except negative. This means that they travel with the same steepness but one goes up and the other goes down.

However, they have the same y-intercepts. This means that they both intercept the same point on the y axis. Wherever two equations intercept is their solution.

Therefore, these two equations have one solution.

I hope this helps!

how can i solve 3x+y=4​

Answers

Answer:

it will end out to be y = -3x + 4

Step-by-step explanation:

you want to get y by itself, so you would subtract the 3x from the left side, which would get you y = -3x + 4

Rewrite the equation by completing the square.
x^2 - 4x + 3 = 0

Answers

Answer:

the answer would be x=3,1

Answer:

After completing the square, we can say:

(x - 2)² = 1

If we solve for x, this tells us that x has a value of both 1 and 3.

Step-by-step explanation:

Given:

x² - 4x + 3 = 0

We can complete the square by adding 1 to both sides:

x² - 4x + 4 = 1

(x - 2)² = 1

We can then solve for x by saying:

(x - 2)² = 1

x - 2 = √1

x = 2 ± 1

x = 1, 3

- step one :
for the first equation
given that x=-10
f(x) =2x-4 if 3x exists in this domain
substituting x in the equation we have
f(-10)=2(-10)-4
f(-10)= -20-4
f(-10)=-24

step two :

Ok so (-2)^3 means -2 x -2 x -2

Now -2 x -2 = 4
Because minus into minus is plus

4 x -2 = -8
Because minus into plus is minus

Therefore, we can see that -2 x -2 x -2 = -8

Which is the same as saying (-2)^3 = -8

Answers

Answer:

simply need to change its sign

Step-by-step explanation:

To find the opposite value of an integer you simply need to change its sign. Meaning that if a given integer is positive then you change the positive into a negative. This would give you the opposite value of that integer which is located at the same distance from 0 but on the other side of the number line. For example, the opposite value of 5 would be -5, while the opposite value of -8 would be 8

Step-by-step explanation:

Find the integer that is

A rectangle has a perimeter of 600 cm. The width of the rectangle is 40 cm less than the length. What is the length of the rectangle, in cm?

Answers

Answer:

170cm

Step-by-step explanation:

Given data

perimeter of 600 cm

let the Length be x

L=x

W= x-40

P=2L+2W

600=2(x)+2(x-40)

600=2x+2x-80

600= 4x-80

600+80= 4x

680= 4x

divide both sides by 4

x= 680/4

x=170

Hence the length is 170cm
