Sadie's earnings varys directly with the number of hours worked.

The number of hours worked in a week where her earnings would be $210 is 20 hours.

Direct variation is when two variables move in the same direction. If one variable increases, the other variable increases. Sadie's earnings increase with hours worked. This is a direct variation.

Hours worked = Total earnings / earning per hour

210 / 10.50 = 20 hours

Answer:

50 calories

Step-by-step explanation:

One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. The fraction that comes from fat:

= 90/150 = 3/5

One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. The fraction that comes from fat here:

= 12/120 = 1/10

The fat that are provided by a 100 calorie serving of the microwave popcorn would be:

= 3/5 × 100

= 60

The fat that are provided by a 100-calorie serving of the pretzels would be:

= 1/10 × 100 = 10

The difference from fat that are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels would be:

= 60 - 10

= 50 calories

Answer:

  C.  x - y > x

Step-by-step explanation:

You can compare the values of these expressions by using numerical values for x and y.

__

We can let x = 1 (a positive integer), and y = -1 (a negative integer).

  y > x + y

  -1 > 1 + (-1)

  - 1 > 0 . . . . . . false

  y < xy

  -1 < (1)(-1)

Answer:

The equation to find Hannah's age is  2h - 2 = 92.

This yields Hannah's age as 47 years.

Step-by-step explanation:

Let h = Hannah's age.

Hannah is older than her sibling, and their ages are consecutive odd integers. Therefore, h = an odd number and the sibling's age =  h-2.

The sum of their ages is 92, therefore

h + (h-2) = 92

2h - 2 = 92

2h = 94

h = 47 years

Answer:

-7.6

Step-by-step explanation:

there are many correct answers for this problem

The number that is greater than -7.81 and less than -7 is -7.41. This can be written as -7.81 < -7.81 < -7. This is obtained by taking the midpoint or middle integer of the given integers.

Given that a number that is greater than -7.81

so, we can write -7.81 <?

And it is also given that the same number which is less than -7. we can write it as -7 >?

So, from this two we can state that the number which is required lies in between the given two integers.

so, we can write -7.81 <?< -7

To find this, we are applying the average for the two integers.

⇒ -7.81 - 7 = -14.81

⇒ -14.81/2 =-7.405 ≅ -7.41

The obtained number satisfies the given conditions

-7.81 < -7.41 and -7 > -7.41

Therefore, the required number is -7.41.

The line perpendicular to y - 3 = 4(x+2) is y-3 = -1/4(x+2)

Two lines are said to be perpendicular if the product of their gradient is -1.

which means m1 x m2 = -1

Analysis:

y - 3 = 4(x+2)

y = 4x + 8+3

y = 4x + 11    m1 = 4

so m1 x m2 = -1

m2 = -1/4

so from the options, the equation with a gradient x = -1/4 is C, y-3 = -1/4(x+2)

In conclusion, the line that would be perpendicular to y - 3 = 4(x+2)
