Answer:

6710.46x

Step-by-step explanation:

The solution is : the value of x is x = 9.75.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

You need to convert from mixed number to decimal number. To do this you can follow the steps shown below:

Step 1: You must divide the numerator of the fraction by the denominator of the fraction.

Step 2: Now you must add the quotient obtained to the Whole number part.

So, you get:

3 + 1/4

=3 + 0.25

= 3.25

Then, the scale image that maps "Figure a" onto "Figure b" is:

1: 3.25

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure a" by .

Therefore, you get that the result is:

x = 3 * 3.25

or, x = 9.75

Hence, The solution is : the value of x is x = 9.75.

Step-by-step explanation:

Probabilities are used to determine the chances of events

The probability that two boys are selected is 0.1517

The given parameters are:

Boys = 12

Girls = 18

Total = 30

Given that the selection is without replacement, the probability that two boys are selected is:

p = 12/30 * 11/29

So, we have:

p = 0.1517

Hence, the probability that two boys are selected is 0.1517

Step-by-step explanation:

Basic info you need to know first:

Left triangle:

[tex]\frac{1}{2} (6)(7)=\frac{42}{2}=21[/tex]

Right triangle:

[tex]\frac{1}{2}(7)(5)=\frac{35}{2}[/tex]

(-3, -1); x = -3; y = -1

Step-by-step explanation:

-3x + 5y = 4; x + y = -4

solving via substitution

rearrange second equation: y = -x - 4

-3x + 5(-x - 4) = 4

-3x - 5x - 20 = 4

-8x -20 = 4

-8x = 24

x = -3

- 3 + y = -4

y = -1

(-3, -1)

The sorted inputs in order from least to greatest is:

3/21 < 3/15 < 3/11 < 3/8 < 3/7

Step-by-step explanation:

Using the given inputs:

3/15 3/7 3/21 3/8 3/11

As the least common denominator (LCD) is: 9240

Rewriting as equivalent fractions with the LCD:

3/15                  3/7                       3/21                 3/8                     3/11

1848/9240      3960/9240       1320/9240        3465/9240        2520/9240

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

    3/21                3/15                 3/11                     3/8                  3/7

1320/9240  < 1848/9240 < 2520/9240  < 3465/9240   <   3960/9240

Therefore, the sorted inputs in order from least to greatest is:

3/21 < 3/15 < 3/11 < 3/8 < 3/7
