Answer:

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = (4/3)πr³

When you have several of these calculations to do, it is convenient to let a graphing calculator or spreadsheet do them. A spreadsheet can do the rounding for you, too. The results are attached. The units are the cube of the units of the radius.

Example calculation:

  (4) Radius = diameter/2 = 13.5 cm/2 = 6.75 cm

  V = (4/3)π(6.75 cm)³ = 4.18879 × 307.547 cm³ = 1288.2 cm³

Note that the constant (4/3)π ≈ 4.18879 remains the same for each calculation. All you need to do is multiply that by the cube of the radius.

2nd option ,

A is correct, B is incorrect, C is correct

Answer:

Area= 70x^3y^2

Perimeter = 20x^2 + 14 xy^2

Step-by-step explanation:

Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 .  The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.  

Answer:

9

Step-by-step explanation:

x+1/3x=12

(3x+1x)/3=12

4x/3=12

4x=12×3

4x=36

x=36/4

x=9

Answer:

1/3+x=12(cross multiply)

x+1=12*3

x+1=36(collect like terms)

x=36-1

x=35

Answer:

S(10)=3*(1-(5/3)^10)/(1-5/3)

Step-by-step explanation:

It is Geometric series with r:

r=5/3=(25/3)/5=5/3

a=3

Sum of G.S. in formula:

S(n)=a(1-r^n)/(1-r)

S(10)=3*(1-(5/3)^10)/(1-5/3)

=246.5725...

Answer:

(-7, -8)

Step-by-step explanation:

Yes, this is the same answer as the other person, but I just included the other factors, a picture of my table, and the answer to part two is "The pair (-7, -8) equal the coefficient of the x-term in the trinomial."

Have a great day, I hope this helps you or anyone else who might've needed this!

Answer:

$28

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 70 × 0.1 × 4 = 28

I = $ 28.00

The simple interest accumulated

on a principal of $ 70.00

at a rate of 10% per year

for 4 years is $ 28.00.

Answer:

Last option is the correct answer

Step-by-step explanation:

None of these choices are correct.

Correct order would be,

Since,

58° < 59° < 63°

Therefore,

AC < CB < AB

AC, CB, AB (this is the correct order of the sides from shortest to longest.)

Answer:

.47

Step-by-step explanation:

9 gumballs in all

7 of them are not green

'ng' = not green

P(ng,ng,ng) = 7/9 x 7/9 x 7/9 = .47

The probability will be 0.87.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that,

Number of Pink gumballs = 3,

Number of Red gumballs = 4,

Number of Green gumballs = 2,

Now,

Total number of gumballs = 3 + 4 + 2 = 9,

Thus, total number of ways of selecting 3 gumball

= 9 x 9 x 9

= 729

Number of Green gumballs = 2

Number of gumballs other than green = 9 - 2 = 7

So, Number of ways to draw 3 gumballs other than green is;

= 7 x 7 x 7

= 243

And, Number of ways to draw one green and two other gumballs in 3 draw = 2 x 7 x 7 + 7 x 2 x 7 + 7 x 7 x 2

       = 294

( Since the green gumballs can be drawn in 1st, 2nd, and 3rd draw.)

Thus, The probability of not drawing all 2 green gumballs is;

= 343 + 294 /729

= 637/729

= 0.87

So, The probability will be 0.87.

Answer:

P=16 cm.

Step-by-step explanation: it is 16 inches

Answer:

To find the perimeter, you do 2 x length + 2 x width

So it would be, 2x4 + 2x6 = 20 inches

You didn't measure properly!!!

Personally, I think you meant to write 3 and 5, that would make 16

Answer:

f(- 2) = 8

Step-by-step explanation:

To evaluate f(- 2) , substitute x = - 2 into f(x) , that is

f(- 2) = 3(- 2)² + (- 2) - 2 = 3(4) - 2 - 2 = 12 - 4 = 8

Answer:

7 1/3

Step-by-step explanation:

The answer is in the simplest form already.

Rewrite the equation:

2 + 1/2 - 9 - 5/6

2 - 9 = -7 (negative 7)

1/2 minus 5/6 = ?

Find LCD of 1/2 and 5/6 and rewrite to solve.

3/6 is the LCD, so:

3/6 - 5/6 = -2/6

-2/6 = -1/3

So, the answer is:

-7 -1/3 = 7 1/3
