Step-by-step explanation:

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:

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

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.

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.

Step-by-step explanation:

i think It is 21! Let me know if i is wrong.

The midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).

The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates:

((x1 + x2)/2, (y1 + y2)/2)

In this case, the endpoints are (-1, -6) and (4, 5), so we can plug in the values:

((x1 + x2)/2, (y1 + y2)/2) = ((-1 + 4)/2, (-6 + 5)/2)

Simplifying this expression, we get:

((x1 + x2)/2, (y1 + y2)/2) = (3/2, -1/2)

Therefore, the midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).
