Answer:

24 cm

Step-by-step explanation:

Answer:

24cm

Step-by-step explanation:

V= 4/3πr³

or, r³= 3/4π ×V= 3/4π× 18432π= 13824

or, r= (13824)^1/3= 24cm

Step-by-step explanation:

Solve the inequality:

[tex]3x - 11 > 7x + 9[/tex]

Rearrange unknown terms to the left side of the equation:

[tex]3x - 7x > 9 + 11[/tex]

Combine like terms:

[tex] - 4x > 9 + 11[/tex]

Calculate the sum or difference:

[tex] - 4x > 20[/tex]

Reduce the greatest common factor for both sides of the inequality:

[tex] - x > 5[/tex]

Divide both sides of the inequality by the coefficient of variable:

[tex]x < - 5[/tex]

2: plot:

[tex]x < - 5[/tex]

Graph on number line:

The solution inequality that represents the solution of the given expression inequality is → x < - 5.

Given is the inequality as follows -

3x – 11 > 7x + 9

The inequality is given as -

3x – 11 > 7x + 9

3x > 7x + 9 + 11

3x - 7x > 9 + 11

- 4x > 20

x < - 5

Therefore, the solution inequality that represents the solution of the given expression inequality is → x < - 5.

Answer:

b=5

Step-by-step explanation:

the answer is in the image above

Answer:

5

Step-by-step explanation:

The Pythagorean Theorem states that a^2 + b^2 = c^2 for right triangles where a and b are the legs and c is the hypotenuse.

In the image, b and 12 are legs and 13 is the hypotenuse, so b^2 + 12^2 = 13^2 -> b^2 = 13^2 - 12^2 = 169 - 144 = 25 -> b = 5

I hope this helps! :)

What two numbers multiply to -10 and add to 3

5*-2 = -10

5+-2 = 3

(x+5)(x-2)

Answer:

1/3

Step-by-step explanation:

3x -9y =4

To find the slope get the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)

Subtract 3x from each side

-9y = -3x+4

Divide each side by -9

-9y/-9 = -3x/-9 +4/-9

y = 1/3x -4/9

The slope is 1/3 and the y intercept is -4/9

Here,

3x -9y =4

To find the slope get the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)

Subtract 3x from each side

-9y = -3x+4

Divide each side by -9

-9y/-9 = -3x/-9 +4/-9

y = 1/3x -4/9

The slope is 1/3 and the y intercept is -4/9

Answer:

It's actually 13 groups

4 students will be left over

Step-by-step explanation:

Add all the students together

134

Divide 10

13 and remainder 4

Answer:

13 ; 4

Step-by-step explanation:

Total students = 24 + 21 + 33 + 36 + 20 = 134

grups that will be made = 134 : 10 = 13,4 = 13

13 x 10 = 130

Students that will be left overs = 134 - 130 = 4

Answer:

The final speed after collision of the first ball that weighs 4 kg will be 8.5 m/s.

Step-by-step explanation:

M1 = 4

M2 = 2

V1 = 8

V2 = 6

V2f = 5

V1f = ?

Rep. Situation with Momentum formula:

M1*V1+M2*V2 = M1*V1f+M2*V2f

Rearrange:

((M1*V1+M2*V2)-M2*V2f) / M1 = V1f

Calculate:

((44) - 10) / 4 = V1f

V1f = 8.5

Answer:

A =196 cm^2

Step-by-step explanation:

The perimeter of a square is

P = 4s where s is the side length

56 = 4s

Divide by 4

56/4 = 4s/4

14 =s

The area is given by

A =s^2

A =14^2

A =196 cm^2

bro/sis through this solution u can solve ur values

Step-by-step explanation:

To calculate the variance, you first subtract the mean from each number and then square the results to find the squared differences. You then find the average of those squared differences. The result is the variance. The standard deviation is a measure of how spread out the numbers in a distribution are.

Answer:

-5

Step-by-step explanation:

4+2(x-4) = -7(x+7)

First, work out parenthesis: 4+ 2x-8 = -7x -49

Combine like terms: 2x-4= -7x-49

now isolate x by first adding 49 to each side: 2x+45= -7x

Then subtract 2x from each side: 45= -9x

Last, divide both sides by -9:

x= -5

Answer:

The answer is negative five or -5.

Step-by-step explanation:

First, you need to distribute your equation and at the end, the -4 should be just 2x - 8.

Second, subtract the numbers 4 and -8, which will equal to -4.

Third, rearrange your terms. Those terms would be -4 + 2x, so it should be 2x - 4.

Fourth, distribute again but with -7(x + 7) and you should get -7x - 49.

Fifth, add four to both sides of your equation. It should be like 2x - 4 + 4 = -7x - 49 + 4.

Sixth, add the numbers for the both sides. Therefore, you have 2x = -7x - 45.

Seventh, add 7x to both sides of the equation. You add it to 2x and -7x - 45 + 7x.

Eighth, simplify by combining like terms which you get 9x = -45.

Ninth, divide both of the sides of your equation by the same term. Your number to use when diving is 9.

Tenth, simplify but cancel terms that are both the numerator and denominator. Then you divide the numbers and get -5.

Answer:

Step-by-step explanation:

Apply the Distributive Property of Multiplication.  Multiply each of the three terms inside parentheses by -(1/2):

(3/4)x - 3x - (1/2) - 3x, or

(3/4)x - 6x - 1/2

The first two terms can be combined, to obtain:

(-5 1/4)x - 1/2, or (-21/4)x - 1/2

Answer:

x = 2 and y = 4

Step-by-step explanation:

Given:

Consider the given expression is:

[tex]\dfrac{2c-a}{3c+b}-\dfrac{5a+4c}{c-a}[/tex]

To find:

The value of the given expression for [tex]a=3, b=-2, c=-4[/tex].

Solution:

We have,

[tex]\dfrac{2c-a}{3c+b}-\dfrac{5a+4c}{c-a}[/tex]

Substituting [tex]a=3, b=-2, c=-4[/tex], we get

[tex]\dfrac{2(-4)-(3)}{3(-4)+(-2)}-\dfrac{5(3)+4(-4)}{(-4)-(3)}[/tex]

[tex]=\dfrac{-8-3}{-12-2}-\dfrac{15-16}{-4-3}[/tex]

[tex]=\dfrac{-11}{-14}-\dfrac{-1}{-7}[/tex]

[tex]=\dfrac{11}{14}-\dfrac{1}{7}[/tex]

Taking LCM, we get

[tex]=\dfrac{11-2}{14}[/tex]

[tex]=\dfrac{9}{14}[/tex]

Therefore, the value of the given expression for [tex]a=3, b=-2, c=-4[/tex] is [tex]\dfrac{9}{14}[/tex].
