What is the perimeter of this figure
40 in.
10 in.
50 in.
18 in.

Answer:

This is a proportion

Step-by-step explanation:

Cross multiply:

12 * 20 = 16 * 15

Simplifying:

12 * 20 = 16 * 15

Multiply 12 * 20

240 = 16 * 15

Multiply 16 * 15

240 = 240

Add '-240' to each side of the equation.

240 + -240 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 0

Solving

0 = 0

Answer:

[tex]\sqrt{3}[/tex]

Step-by-step explanation:

See attachment 1. This is the formula to use.

There are two numbers, so n=2. Plugging them into the formula, you get

[tex]\sqrt[2]{6*\frac{1}{2}} \\[/tex]

Now, putting a 2 in front just means we're finding the square root, so I'll get rid of it. Then, just do the calculation.

[tex]\sqrt{6*\frac{1}{2}}=\sqrt{\frac{6}{2}}=\sqrt{3}[/tex]

Answer:

√3

Step-by-step explanation:

To find the Geometric mean, multiply the values given, then take the square root.

x² = ab

x= √ab

It's a "central tendency" we are calculating.

This is different from the arithmetical mean which uses addition and division to find that average.

Answer:

1/4

Step-by-step explanation:

3/4 is also equal to 6/8. And 1/2 is also equal to 4/8.

So the order would be 6/8, 5/8, 4/8, 3/8 and then 2/8. Which would simplify to 1/4.

Answer:

1/8 ????

Step-by-step explanation:

dont put this im not really sure sorry :(

Answer:

Step-by-step explanation:

1/2(4x - 16) = 14

2x - 8 = 14             {add 8 to both sides}

 2x = 22               {divide both sides by 2}

   x = 11

Answer:

60 seconds

Step-by-step explanation:

step 1.) find how many meters it falls per second

          40m / 4sec = 10m/s

step 2.) use the equation above to find in terms of the question

          10m/s for 6sec = 10 x 6 ====> 60 seconds

Answer:

41/99

Step-by-step explanation:

Simplest form of the number 0.41 repeating; 41/99

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction.

It can be written as the form of p : q, which is equivalent to p / q.

We are Given that 0.41 repeating.

Consider x = 0.41, then multiply both sides of this equation by 100 to remove the decimal point:

100x = 41.41

Simplifying;

99x = 41

Dividing both sides by 99;

x = 41/99

Answer:

=3

Step-by-step explanation:

5b/c

=5*6/10

=30/10

=3

Answer:

If b = 6 and c = 10, the value of an expression is 3.

Step-by-step explanation:

Given the expression

[tex]\frac{5b}{c}[/tex]

We have to evaluate the expression if b = 6 and c = 10.

Important Tip:

In order to evaluate the expression  [tex]\frac{5b}{c}[/tex], all we need to do is to substitute the value of b and c in the expression.

As the expression is

[tex]\frac{5b}{c}[/tex]

substitute b = 6 and c = 10 in the expression

[tex]\frac{5b}{c}=\frac{5\left(6\right)}{10}[/tex]

     [tex]=\frac{30}{10}[/tex]

      [tex]=3[/tex]       ∵ [tex]\frac{30}{10}=3[/tex]

Therefore, if b = 6 and c = 10, the value of an expression is 3.

Answer:

Step-by-stepexplanation:

The y axis is the vertical line. b is y intercept, meaning where the line crosses the y axis. here b is 2, so plot a point on (0,2). m is the slope. slope is rise/run, and your slope is -1/2. this means your rise is negative one, (go down one) and you run is positive two (go two to the right) and plot your point. then you connect this point to the first point and extend the line on both sides. hope this helps :)

Answer:

C- 42

Step-by-step explanation:

Answer:

C. x=42

Step-by-step explanation:

16 + 3x + y = 180

126 + 16 + y = 180

y = 38

16 + 3x + 38 = 180

54 + 3x = 180

3x = 126

x=42

Answer:

C) 23

Step-by-step explanation:

If the computer monitor is 20 inches wide, and 12 inches high, we can solve for the diagonal by using the Pythagorean theorem.

Let a = the width, let b= the height, let c = the diagonal.

a^2 + b^2 = c^2

20^2 +12^2 =c^2

400 + 144 = c^2

544 = c^2

C is approximately equal to 23 inches.
