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.

Answer: 112in^2

Step-by-step explanation:

area of rectangle is

10 x 10  = 100 in ^2

then area of the triangle

h x b / 2 = 12 in^2

so 100 + 12 = 112 in^2

Answer:

Step-by-step explanation:

[tex]\frac{16}{x^{12}}[/tex].

We get this by distributing the 4 into each term. 2^4 is 16 and (x^-3)^4 is x^-12 which is equal to 1/x^12

Answer:

16/x^12

Step-by-step explanation:

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.

Answer:

C

Step-by-step explanation:

a(0.62)+4(1.00)/a+4+78/100

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.

Answer:

10.5

Step-by-step explanation:

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

good luck :)

**please let me know if this was incorrect/ not what you were looking for or both**

Answer:

4.75 to 7.5

Step-by-step explanation:

just look at it or use a pencil to draw lines to proportion

Answer:

k is constant of proportionality

Monday: k = 7.5

Tuesday: k = 2

Step-by-step explanation:

The equation for proportionality is y = kx

Take the first line of the table, plug it in and solve for k. Do that with at least 1 other row to be sure k is the same.

15 = (k)(2)

k = 7.5

Same thing for this day. x is the horizontal, y is the vertical.

16 = (k)(8)

Answer:

I think it is 68cm

Step-by-step explanation:

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

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.

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 .

Answer:

<1 = 50

<2 = 40

<3 = 90

<4 = 90

<5 = 40

<6 = 50

<7 = 130

Step-by-step explanation:

<5 + <6 = 90

40 + <6 = 90

<6 = 50

<5 = <2 because of vertical angles

<2 = 40

<6 = <1 because of vertical angles

<1 = 50

<7 = <4 + <5

<7 = 90 + 40

<7 = 130

Answer:

Solution given:

<4=90°[vertically opposite angle]

<2=<5=40°[vertically opposite angle]

<3=90°[right angle]

again

<1+<2=90°[right angle]

<1=90°-40°=50°

<1=50°

again

<5=40°[given]

<6=<1=50°[vertically opposite angle]

<6=50°
