A company lost an average of $30,000 per month. Find the total loss of the company in 1 year.

Answers

Answer:

What is the solution to this math problem[tex]4x + 2(x - 5) = 3(2x - 4)[/tex]

Answers

[tex]4x+2(x-5)=3(2x-4)\\\\4x+2x-10=6x-12\\\\4x+2x-6x=-12+10\\\\0=-2[/tex]

Equation doesn't have any solution.

4x+2 (x-5) = 3(2x-4)
4x+2x-10 = 6x-12
6x -10 = 6x -12

Since the 6x will get canceled from both sides of the equation, this problem has no proper solution

Answers

An answer could be 7.7899775796… because it is not a terminating or repeating decimal.

Answer:

[tex]\sqrt{60}[/tex], which is 7.745966692414834 and continuing.

Step-by-step explanation:

An irrational number is one that cannot be displayed on a simple fraction, so the easiest way to find an irrational number is to square root a number which is not a perfect square.

Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?

Answers

Answer:

2 4/36

Step-by-step explanation:

To do this, multiply the whole number by the denominator and add it to the numerator.

8 x 9 = 72

72 + 4 = 76

76/9

Then multiply across (multiply numerators with numerators; denominators with denominators)

76 x 1 = 76

9 x 4 = 36

76/36 = 2  4/36

____________________________

A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.

1/4 x 8/1 = 8/4 = 2

1/4 x 4/9 = 4/36

 = 2  4/36

Answer:

2 1/9

Step-by-step explanation:

Multiplying fractions: Numerator times numerator over denominator times denominator. IF you have a mixed number, convert it into improper fraction, then do numerator times numerator over denominator times denominator.

1/4 x 76/9 (I got 76/9 because the 8 means 8 9/9s, so (8 x 9)=72 plus 4 because 4/9s=76/9)

1/4 x 76/9= 76/36

=38/18

=19/9

=2 1/9

Tell whether the given statement is true or false. Explain your choice.
7. All real numbers are rational.
8. All whole numbers are integers.

Answers

For number 7 since the rational number is countable, and the set of real numbers is uncountable, almost all real numbers are irrational. So you should choose false

8 yes! All whole numbers are integers. For an example 0 is a whole number, 0 Is ALSO a integer. So you should choose truth
7. False. Since the set of rational numbers is countable, and the set or real numbers is uncountable, almost all real numbers are irrational.
8.true. All whole numbers are integers, so since 0 is a whole number, 0 is also an integer

what is the area of a semi circle when the diameter is 6

Answers

Answer: 14.13

Step-by-step explanation:

Your answer is 14.13

First, the formula for area of a semi circle is 3.14 x r^2 and divide by two.

To find the radius, we need to divide the diameter by two, which is 3.

So like

3.14 x 3^2/2

3.14 x 9/2

28.26/2

A=14.13

Answer:

14.13

Step-by-step explanation:

normal circle area equation = r^2*3.14

6/2=3

3*3*3.14

= 28.26

it's a semicircle so /2

=14.13

Answer:

Range=88°−30°=58°F

The Range is the difference between the highest and the lowest values.

It tells us how far apart or how how widely spread the values are.

Range=88°−30°=58°F
