Answer:

Perhaps the most important reason to study math is because the study of mathematics builds problem-solving skills. All citizens need to know how to reason and analytically think through a problem. The habits of mind associated with learning mathematics trains our brains to seek solutions in a logical way. Math will help you through your everyday life. It could even help you through colleges and or jobs. Paying for stuff in a store you must know how much you have to pay with your money. If your cashier you have to know how much change they need back. Math is super important. It helps with so many things.

Answer:

C. 20 minutes

Step-by-step explanation:

If Victor (V) worked alone, it would take him 30 minutes.

30 * V = 1

V = 1 / 30

When x represents the number of minutes it would take Dennis (D) working alone,

x * D = 1

D = 1 / x

Working together, they would finish in 12 minutes

12 (V + D) = 1

12( 1/30  + 1/x) =1

1/30 + 1/x = 1/12

Multiply all through by x

x/30 + 1 = x/12

x/30 - x/12 = - 1

( 2x - 5x ) / 60 = - 1

- 3x / 60 = - 1

- 3x = -60

x = -60 / -3 = 20 minutes

Answer:

Since

Angle FCG and Angle BCG are equal (Since CG is the bisector)

9x + 3=13x - 9

4x = 12

x=12/4

x = 3

X=3

Answer:

I think the answer will be 20. It is oppsite sides and the lines look even. The area is small as well. So I think 20˙ will be the best option.

a). 20°

The angle x is equal to 20° because vertical angle.

For determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Given that,

Now if we square both the numbers so it comes:

So, 121 is nearest to 120.

Therefore we can conclude that for determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Answer:

z = [tex]\frac{4x}{y}[/tex]

Step-by-step explanation:

Given z varies directly with x and inversely with y then the equation relating them is

z = k × [tex]\frac{x}{y}[/tex] ← k is the constant of variation

To find k use the condition z = 10 when x = 5 and y = 2, then

10 = k × [tex]\frac{5}{2}[/tex] ( multiply both sides by 2 to clear the fraction

20 = 5k ( divide both sides by 5 )

4 = k

z = [tex]\frac{4x}{y}[/tex] ← equation of variation

The function that models the asked relationship is 4x / y

A variation is a relation between a set of values of one variable and a set of values of other variables.

Given that, z varies directly with x and inversely with y then the equation relating them is,

z = (k × x) / y, where, k is the constant of variation

Finding k by using the condition z = 10 when x = 5 and y = 2, then

10 = (k × 5) / 2

20 = 5k

k = 4

Therefore, the equation of variation is 4x / y

Hence, the function that models the asked relationship is 4x / y

Answer:    y= -22

Step-by-step explanation:

Set up a proportional relationship and solve  

If y is -6 and x will be 3   then what will y be when x is 11. \

We can represent that situation like this,

[tex]\frac{-6}{y} = \frac{3}{11}[/tex]    cross multiply  

3y = -66     Divide both sides by 3

y = -22

Answer:

330 + 33 = 363

Step-by-step explanation:

The answers you are looking are 330 and 33.

If you were to take 330 and 33 and add them together, it would equal 363. The question also states if you were to take the 0 off of the first number (330), youd get your second number (33) to equal the sum given.

Step-by-step explanation:

Johnny mows lawns after school and earns $10 per hour.

Let the number of hours h mows = x

Total earning of Johnny = $10x

If the earning is represented by the variable 'y' equation representing the total earnings will be.

y = 10x

Answer: Option D: Inequality.

Step-by-step explanation:

A relation between two unequal values that are compared using the symbols > and <, such like:

A < B    (A is less than B)

A > B (A is greater than )

Are called inequalities.

This is because this is a relation between two unequal values.

Then the correct option is D.
