Answer:

above is the solution to the question

Answer:

Volume for a cylinder in this case is

V=˜ πr^2h

So R being radius

H being height

V being volume.

We know the volume is 250π

The height is given in the diagram which is 10.

Plug in the infromation into the formula.

250π = πr^2*10

Simplify and solve for r (radius).

Let’s divide by π on both sides

250 = r^2 * 10

Divide by 10 to get rid of 10

25 = r^2

√25 = r

√25 = 5

The radius is 5

First you multiply 3 five times, then you multiply 3 seven times and you divide the results of each multiplication

Answer:

0.111111111111111

Step-by-step explanation:

=> 3⁵÷3⁷

Note 3⁵ means multiplying 3 five times

And 3⁷ means multiplying 3 7 times

=> 3×3×3×3×3÷3×3×3×3×3×3×3

multiply the values and then divide

=> 243÷2,187

divide 243 by 2187

=> 0.111111111111111

Answer:

p=m*9+9

So 45/4=9

9*4=36

36+9=45

Check with table

5*9=45

45+9=54

6+9=54

63+9=63

7+9=63

63+9=72

So as you can se the equation is p=9*m+9

Hopes this helps!

Answer:

Depends on the pool you are pulling them from.

There are currently 11 different denomination accessible.

That would be 1 out of 11.

But considering that 4 of those bills are uncommon, the odds become 1 out of 7

Then to pull 2 of the same would mean you multiply 1/11 by 1/11 = 1/121

for the 1/7 it would become 1/49

Step-by-step explanation:

look at a die, for example.

the probabilty to roll a 6 is 1/6 (if all numbers truly have the same probability due to a perfectly balanced die).

so, you expect as a mean value that you have to roll the die 6 times to get one 6.

now in our general example :

20% = 1/5

so, we expect event A to happen once as a mean value every 5 attempts.

now we do 40 attempts. that means 8×5 sets of attempts.

and we therefore expect to see event A 8 times.

Step-by-step explanation:

m <HGJ + m <KGJ =180°

So, m <HGJ = 180° - m <KGJ = 180° - 86° =94°

Answer:

x=16°

x+46°=62°(The external angle formed by the base of a triangle is equal to the sum of the two intersecting angles.)

x=62°-46°

x=16°

Answer:

y-intercept is 3

The point where the line intercepts the y-axis is (0, 3)

Step-by-step explanation:

Slope-intercept form of a linear equation:  [tex]y=mx+b[/tex]

(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)

Given equation of line:  [tex]y=3-4x[/tex]

Rearrange:  [tex]y=-4x+3[/tex]

Therefore, the slope of the line is -4 and the y-intercept is 3.

FYI the line intercepts the y-axis when x = 0, so you can input x = 0 into the equation to find y ⇒ (0, 3)

Answer:

The y-intercept of the line is 3.

Step-by-step explanation:

Formula: y = mx + b

y = 3 - 4x

y = -4x + 3

On the formula, "b" means y-intercept. Therefore, the y-intercept of the line is 3.

Answer:

22.608 units

Step-by-step explanation:

Basically, the circumference of a circle is the distance around a circle, sort of like the perimeter of a figure. It has a unique formula which is [tex]C=2\pi r[/tex] where [tex]r[/tex] is the radius, which is the distance between the circle and its center. Using our given information, we can find the circumference:

[tex]C=2\pi r\\C=2(3.14)(3.6)\\C=22.608[/tex]

Therefore, the circumference of a circle with a radius of 3.6 units is 22.608 units.

Answer:

Circumference is...

Step-by-step explanation:

Multiply the radius by 2 to get the diameter.

Multiply the result by π, or 3.14 for an estimation.

That's it; you found the circumference of the circle.

dont worry I already took this lesson.

Step-by-step explanation:

Solve the problem step by step.

First,

Base area: 6 * 2.5 = 15

Then,

The area of the two smallersides:

2.5 * 4 = 10

10 * 2 = 20

After that,

The area of the two larger sides:

6 * 4 = 24

24 * 2 = 48

After all of the calculations, you add all of the sums up:

15+20+48

Which equals 83.

The equation form for this problem would be:

(6*2.5) + 2(2.5*4) + 2(6*4) = 83

Hope this helps and it wasn't too confusing!
