Answer:

12.15

Step-by-step explanation:

3/20 = 15/100 = 0.15

Explanation:

Decimals are way of writing fractions which have denominators that are powers of 10

0.3 = 3/10

0.38 = 38/100

0.384 = 384/1000

etc

Find an equivalent fraction for 3/20

3/20× 5/5 = 15/ 100

This can now be written as

0.15

and the remaining whole twelve you are to add

so it would be 12.15

Answer:

12.15

Step-by-step explanation:

It is 12.15 because you have 12, right? 3 divided by 20, gives you 15.

Another way you can use to find the answer is taking 3/20 from 12 3/20, and then 3/20 equals 15/100. As a decimal it will be 12.15

Hope this helps!

ANSWER

The correct answer is A

{ $x|-5$ }

EXPLANATION

$|x|$

This implies that

$x$

We solve the compound inequality to obtain,

$x-5$

Remember that, dividing through by negative 1 reverses the inequality sign

The solution set is

{ $x|-5$ }

A number cube with faces labeled 1 through 6 is rolled 200 times. About how many times would you expect to roll an even number?

Sergio039 [100]

Answer:

The theoretical probability is smaller than the relative frequency

Step-by-step explanation:

6-sided cube rolled 200 times

Probability of an even number is 1/2= 0.5

200*1/2= 100- theoretical probability

Experimental frequency= 115

Relative frequency= 115/200= 0.575

0.575 > 0.5

The theoretical probability is smaller than the relative frequency

Find the length of the missing side. the triangle not drawn to scale. (Image attached)

3241004551 [841]

Answer: 8

Step-by-step explanation:

The triangle shown in the image attached is a right triangle.

Therefore, to calculate the missing lenght of the triangle you can apply the Pythagorean Theorem, which is shown below:

$a^2=b^2+c^2$

Where a is the hypotenuse and b and c are the legs.

The problem gives you the value of the hypotenuse and the value of one leg. Therefore, you must solve for the other leg from $a^2=b^2+c^2$ , as following:

$17^2=15^2+c^2\\c=\sqrt{17^2-15^2}\\c=8$

Therefore, the lenght of the missing side is: 8

What is the rule for the pattern 3 12 6 24 12 48 24

schepotkina [342]

Multiply by 4 is your rule

3 x 4 = 12

6 x 4 = 24

12 x 4 = 48

To solve for the answer for 24, multiply it by 4

24 x 4 = 96

96 is the match for 24

hope this helps
