Maggie is planning on going to Penn State University. She estimates that she will need to earn at least $2,000 to live off of ov

er the course of the year after she buys a $450 laptop.
Part A: Let x represent the amount of money she earns over the summer. Write an inequality that describes the situation above.

Part B: Now that her expenses are taken care of, she has $2,000 to start school. Every week she plans to withdraw $30 for food. If x represents the number of weeks she can withdraw $30, write an inequality that describes this situation.

Part C: Solve the inequality in Part B.

Part D: Explain what your answer in Part C means in terms of the number of weeks that Maggie is able to withdraw money for food.

Thanks for your help :)

A. The amount of money she must earn in the summer must be
x ≥ 2450

B. The inequality that describes the situation is
30x ≤ 2000

C. Solving the inequality
x ≤ 66.67 ~ 66 weeks

D. The answer is Part C means that she can only make use of the $2000 money for food for 66 weeks before it's not enough.

Standard Normal Distribution. As discussed in the introductory section, normal distributions do not necessarily have the same means and standard deviations. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution.

What is the sum of the degrees of the interior angles of a 19-gon?
emmasim [6.3K]
Sum of interior angles formula = (n-2) x 180
where n = number of sides

so,
( 19-2 ) x 180
= 17 x 180
= 3060

ans : A

hope it helps :)

Help with this question please​
Allisa [31]

Step-by-step explanation:

The LKM angle is an enclosed angle. So its size is half the arc facing it.

LKM (angle) = ½ LM (arc)

The LMN angle is a shadow angle. So its size is half the size of the arc facing it.

LMN(angle) = ½ LM(arc)

so:

LKM = LMN

Barry has 17 more than two-thirds of the number of cards in his brother’s baseball card collection. If x represents the number o
ioda

Answer:

(2/3) x + 17

Step-by-step explanation:

One way we can solve this is to start at x and to work from there.

Since x represents the number of baseball cards that Barry's brother has, and the closest phrase to it is "two-thirds of the number of cards", we can start by writing that as "2/3 of x", or (2/3) * x.

Next, we have "17 more than two-thirds of ...". We have 17 more than the number we just got, so we have 17 more than (2/3) * x = 17 + (2/3) * x =  (2/3)*x + 17 as our answer

A convex hexagon has interior angles with measures x^0, (5x - 103); (2x + 60), (7x - 31), (6x -6), and (9x - 100), what is the v
cestrela7 [59]

Answer:

x = 30.66°

Step-by-step explanation:

The sum of the interior angles of a hexagon is 720°

Each angles are x^0, (5x - 103); (2x + 60), (7x - 31), (6x -6), and (9x - 100),

we add all these angles together

x^0 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100) = 720

x^0  = 1

1 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100)

1 + 5x - 103 +2x + 60 + 7x -31 + 6x - 6 + 9x - 100 = 720

1 - 103 + 60 - 31 - 6 - 100 + 5x + 2x + 7x + 6x + 9x = 720

1 - 180 + 29x = 720

-179 + 29x = 720

29x = 720 + 179 = 889

x = 889/29 = 30.655 ≅ 30.66°
