Elena is trying to figure out how many movies she can download to her hard drive. The
hard drive is supposed to hold 500 gigabytes of data, but 58 gigabytes are already taken up
by other files. Each movie is 8 gigabytes. Elena wrote the inequality and
solved it to find the solution .

1. Explain how you know Elena made a mistake based on her solution.

2. Fix Elena’s inequality and explain what each part of the inequality means.

Answers

Answer 1

Answer: Elena used the "greater than" sign when she should have used the "less than sign".

The correct inequality is 8x + 58 < 500, where 8 is the amount of gigabytes taken up by a movie, x is the amount of movies, 58 is the amount of gigabytes already taken up, and 500 is the maximum storage capacity in gigabytes. The < sign denotes that 500 CANNOT be exceeded.

Step-by-step explanation:

Elena wrote the equation as 8x + 58 > 500, meaning that the amount of gigabytes MUST exceed 500. This does not make sense since a computer would still function even with less movies. Since the hard drive has a capacity of 500 GB, it cannot go higher, making the correct inequality 8x + 58 < 500.

Quadrilateral ABCD is rotated 90° about the origin. Select the graph that shows this rotation.

Answers

First thing is correct I think

The correct graph that shows this rotation is shown in Option 3.

What is Translation?

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

Quadrilateral ABCD is rotated 90° about the origin.

Now, We know that;

Condition of 90° clockwise rotation: (x, y) becomes (y,-x)

Hence, For Option 1;

A = (- 2, - 2)

A' = (2, - 2)

Foe option 2;

A = (- 2, - 2)

A' = (2, 2)

Thus, This shows correct graph of rotation.

Answer:

C. (5-1), (5-2), (5-3), (5-4), (5-5), (5-6)

Step-by-step explanation:

So let's look at the choices and find which one has only one 3 (3's will be boldened for convenience).

A. (1-1), (2-2), (3-3), (4-4), (5-5), (6-6)

A has two three's, so it's out.

B. (1-3), (2-3), (3-1), (3-2), (3-4), (3-5), (3-6), (4-3), (5-3), (6-3)

B has 10 three's, so it's also out.

C. (5-1) (5-2) (5-3) (5-4) (5-5) (5-6)

C has 1 three, so it's correct. However I will still test D to make sure.

D. (1-6) (2-5) (3-4) (4-3) (5-2) (6-1)

D, like A, has two three's, so it's out.

With that information, we can deduce that C has the favorable outcomes for rolling exactly 1 three.

The change in the average price of a gallon
of milk from 2011 to 2013 is shown in the
table below.

At the end of 2010, the price of a gallon of
milk was $3.47.
What was the price, in dollars, of a gallon of milk at the end of 2013?

Answers

Answer:

Price at the end of 2011 :

$3.47 - 0.57 = $2.90

Price at the end of 2012 :

$2.90 + $0.25 = $3.15

Price at the end of 2013 :

$3.15 - $0.08 = $3.07

So, at the end of 2013, the price of a gallon of milk was $3.07 .

If the simple interest on a principal amount of $6000 for 7 years is $2,520, then what is the interest rate as a percent?

Answers

Answer:

6%

Step-by-step explanation:

first multiply $6000 by 7 years then divide 2520 by 42000 to get 0.06

6% because interest= principal amount x rate x time / 100

So 2520=6000xRx7 / 100 = 6%

Find the CIRCUMFERENCE of a circle with a RADIUS of 13mm. Use 3.14 for the value of pi.

Answers

Answer:

Circumference = 81.64

Step-by-step explanation:

The formula for finding circumference is C = pi(d). Since you don't have the diameter, but you do have the radius (which is half of the diameter), you will multiply 13 by 2, or 13 x 2. 13 x 2 = 26. So, the diameter is 26.

Fill in what you know: C = 3.14(26)

Now, all you have to do is multiply 3.14 and 26, which equals 81.64.

Hope this helps! :)

For finding circumference you want to double the radius first to get a diameter. 13mm*2= 26mm so the diameter is 26 now we need to multiply it by 3.14 (the first 3 digits of pi). 26mm*3.14= 81.64mm Hope this helped!!

How many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel? Which of the following equations could be used to solve this?

Answers

Answer:

3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.

Step-by-step explanation:

To determine how many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel, the following calculations must be performed:

50 + 0.62X = 78

0.62X = 78 - 50

0.62X = 28

X = 28 / 0.62

X = 45.16

100 - 45.16 = 54.84

54.84 = 4

45.16 = X

45.16 x 4 / 54.84 = X

180.64 / 54.84 = X

3.29 = X

Therefore, 3.29 milligrams of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel.

C

Carla's library account showed that she owed $4.00 in late fees. She made a payment of $7.00. She then lost a library book and was assessed a $12.00 fine. If Carla then makes a payment of $20, what is her balance after the payment?

Answers

Answer:

$9

Step-by-step explanation:

ok so this is what she owes- **i'm 'separating' them to make it easier**

$4 and $12 so let's add those together-

4+12=$16 so she owes 16 dollars in fines and late fees

and let's remember that she paid $7 for her late fee and assuming that she gets her $3 back she has $3 so far then for the 12 dollar fine she pays 20 dollars, and we're assuming that she gets back $6

she should have $9 left
