SA = 2 pi r * x + 2* pi r^2

r = 6

SA = 2 pi * 6 * x + 2 * pi * 6^2

SA = 12 pi * x + 72 pi

Volume = pi r^2 * x

Volume = pi 36 x

Now volume and surface area are made to be equal so

Volume = Surface area

36 pi x = 12 pi x + 72 pi                 Divide through by pi

36x = 12x + 72                               Subtract 12x from both sides

24x = 72                                        Divide by 24

x =  72/24

x = 3

15 is done exactly the same way. You can try it yourself. Only the numbers are different. Use 10 for the radius. You should get x = 2.5

two members have a sum of 112. If one number is x, represent the other numbers as an expression in x

Answers

Based on the information given, the other number will be 112 - x

Value of the first number = x

Value of the second number = y

Sum of the numbers = 112

Therefore, the value of the second number will be:

x + y = 112

y = 112 - x

In conclusion, the value of the second number is 112 - x.

Answers

Answer:

[tex]x \ge3.5[/tex]

Step-by-step explanation:

First, write the given in the form of a mathematical equation rather than words. I'll call the mystery number given in the question [tex]x[/tex]:

[tex]\frac{5*7}{x} \leq 10[/tex]

Simplify:

[tex]\frac{35}{x} \leq 10[/tex]

Solve for x:

[tex]\frac{35}{x} *x\leq 10*x[/tex]

Simplify the fraction:

[tex]35\leq 10x[/tex]

Divide by 10 to isolate x:

[tex]\frac{35}{10} \leq x[/tex]

Flip the equation around to make it easier to read:

[tex]x \ge \frac{35}{10}[/tex]

Simplify the fraction:

[tex]x \ge \frac{7}{2}[/tex] or [tex]x \ge3.5[/tex]

The number of [tex]x[/tex] satisfying [tex]| x - 2 |^{10x^2 - 1} = |x - 2|^{3x}[/tex] is
A. 5
B. 6
C. 2
D. 4

Answers

Answer:

D. 4

Step-by-step explanation:

Without actually solving the equation, recall that for [tex]a=|b|[/tex], there are two cases:

[tex]\begin{cases}a=b, \\a=-b\end{cases}[/tex]

In the given equation [tex]|x-2|^{10x^2-1}=|x-2|^{3x}[/tex], there are two pairs of absolute value symbols.

Since each has two cases, there must be a total of [tex]2\cdot 2=\boxed{4}[/tex] different equations created.

All four cases are:

[tex]\begin{cases}(x-2)^{10x^2-1}=(x-2)^{3x},\\(-x+2)^{10x^2-1}=(x-2)^{3x},\\(x-2)^{10x^2-1}=(-x+2)^{3x},\\(-x+2)^{10x^2-1}=(-x+2)^{3x}\end{cases}[/tex]

Exponents differ, hence clearly there are four possible solutions to this equation.

You can solve for all four values of [tex]x[/tex] by taking the log of both sides and using a bit of algebra to verify you have four solutions.

Equation : 12v + 10v + 14 = 80

Answers

Answer:

this can be simplified

12v + 10v + 14 = 80

22v + 14 = 80

22v = 66

v = 3

Answer:

v = 3

Step-by-step explanation:

12v + 10v = 22v

22v + 14 = 80

Subtract 14 from both sides.

80 - 14 = 66

22v = 66

now divide both sides by 22

66/22 = 3

v = 3

Answers

Answer: 11

Step-by-step explanation:

Complementary angles mean both angles sum 90°, then:

(3x + 2)° + 5x° = 90°

3x° + 2° + 5x° = 90°

8x° + 2° = 90°

8x° = 88°

x = 11

Confirmation:

(3x + 2)°                                        5x°

(3(11) + 2)°                                      5(11)x°

The perimeter of figure one is four times a number minus three. The perimeter of figure two is two times the same number plus five. The perimeter of figure 1 and figure 2 are the same.

a. Write an equation to find the number
b. Solve the equation to find the number
c. What is the perimeter of Figure 2? Explain.

Answers

Answer:

Let the no. be x.

Therefore,

PERIMETER 1=4x-3

PERIMETER 2=2x+5

Since,

Both PERIMETER are equal .

Therefore,

4x-3=2x+5

2x=8,

x=4

PERIMETER 2 =2×4+5

=13

The answer will be ;

a) The equation to find the number will be 4x-3 = 2x +5

b) After solving the equation we get value of number equal to 4.

c) Perimeter of figure 2 will be equal to 13.

It has been given that there are two figures. Perimeter of figure 1 is four times a number minus three whereas, perimeter of figure 2 is two times the same number plus five.

We have to solve given subparts of the question based on data given.

What is the perimeter ?

Perimeter is the distance around the edge of a shape.

Let the number be x.

Perimeter of figure 1 will be equal to 4x - 3

Perimeter of figure 2 will be equal to 2x + 5

a) As per the question perimeter of both the figures are equal.

   So, the equation will be ,

   4x-3 = 2x+5

b)

4x -3 = 2x + 5

   4x-2x = 3 + 5

   2x = 8

    x = 4

Thus the number is 4.

c) Perimeter of figure 2 = 2x + 5

                                       = (2 × 4 ) + 5

                                       = 13

Thus, the perimeter of figure 2 will be equal to 13.

Step-by-step explanation:

Hi there!

Let x be equal to the smallest integer.

Let (x+2) be equal to the next even integer.

Let (x+4) be equal to the largest even integer out of the three.

We're given:

⇒ smallest number + (2 × middle number) = 20 + largest number

Construct an equation:

[tex]x+2(x+2)=20+(x+4)[/tex]

Combine like terms:

[tex]x+2x+4=20+x+4\\3x+4=x+24\\2x=20\\x=10[/tex]

Therefore, the smallest integer is 10, making the next two even integers 12 and 14.

|-12|

|-26|

Step-by-step explanation:

Basically, the absolute value turns the -'s into +'s so the |-26| turns into a 26. Thus, when you convert the two numbers out of the absolute value, it's easy then on.

Answer:

-15, -12, |10|, |-12|, |-26|

Step-by-step explanation:

The bars around three of the numbers are absolute value bars. The absolute value of a number is its distance from 0. Since distance cannot be negative, a number's absolute value will just be that number but positive. Therefore, the largest number listed is |-26| because it equals 26. Then, -15 is the smallest number represented.
