Step-by-step explanation:
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: 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.
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?
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 .

The mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.
What is mean absolute deviation?It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.
We have data as shown in the picture in the form of frequency graph.
The mean = 11/4 = 2.75
The difference between each value and mean is shown in the attached table.
MAD = 5/4 = 1.25
The nearest value is 1.1.
Thus, the mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

Step-by-step explanation:
Area of triangle:
The formula to find the area of a triangle is 1/2bh
- We plug in the values given.
1/2 x 8 x 7
Which is 28ft.
Area of semicircle:
The formula to find the area of a semicircle is 1/2[tex]\pi[/tex][tex]r^{2}[/tex]
- We plug in the values given
1/2 x [tex]\pi[/tex] x [tex]4^{2}[/tex]
1/2 x 16[tex]\pi[/tex]
8[tex]\pi[/tex] or 8 x 3.14 = 25.12
In order to get the total area of the whole shape we need to add the areas of those two, which will be 25.12 + 28 = 53.12

Answer:
D) 472
Step-by-step explanation:
Surface Area formula:
SA = 2(wl + hl + hw)
Given:
w = 7
l = 12
h = 8
Work:
SA = 2(wl + hl + hw)
SA = 2(7 x 12 + 8 x 12 + 8 x 7)
SA = 2(84 + 96 + 56)
SA = 2(236)
SA = 472

I need the answer asap
Answer:
A = 254.34
3.14 = pi
Step-by-step explanation:
C = 18(3.14)
C = 56.52
A = C^2/4(3.14)
A = (56.52)^2 = 3194.5104
A = 3194.5104/4(3.14) = 254.34

Mimi uses a 7.5-gal bucket to fill a wading pool. She pours 12 buckets full of water into the pool, which can hold up to 138 gal of water. She wants to solve for n, the number of additional full buckets of water she can pour into the pool.
Answer: 6 full buckets.
Step-by-step explanation:
138(pool)/7.5(a bucket)=18.4
18-12=6 full buckets.
URGENT!!! plz help will give brainlist question is in photo
what is the measure of
Answer:
A = 37 degrees ; B = 82 degrees
Step-by-step explanation:
the angle A plus 143 must measure 180 degrees
angle A = 180 - 143 = 37 degrees
the sum of the inner angles of a triangle is 180 degrees
A + B + C = 180
37 + B + 61 = 180
B = 180 - 98 = 82 degrees

The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which is 40% of the total miles of their trip. How many miles is the Jackson’s trip from Boston to New York?
Explain how you solved this problem in the box below. Include a description of your strategy and your answer in your explanation.
Answer:
84 is .4 of the trip
40% times 2.5 is 100% (40+40+20)
so, multiple 84 by 2.5 and that's the answer
84 * 2.5= 210
Answer:
84 is .4 of the trip
40% times 2.5 is 100% (40+40+20)
so, multiple 84 by 2.5 and that's the answer
84 * 2.5= 210
Step-by-step explanation:
sorry for copy write dont report me
please help im lost i dont understand this objective
Answer:
Explained Below
Step-by-step explanation:
You'll want to start off by knowing the formulas for the area and perimeter of triangles:
Area Formula - A= 1/2 bh (1/2 x base x height)
Perimeter Formula - P = a + b + c (sides added together)
So, we will plug in the numbers.
Triangle 1: A = 1/2 bh So, A = 1/2 8 x 10, which means half of 8 or 10 multiplied by the number that you did not half. (For instance: If you half 8, that means you multiply 4 and 10.) Now, you should have A = 40 either way (4 x 10 = 40 and 8 x 5 = 40).
P = a + b + c. So, you will add 8, 6, and 10. This is 14.
Triangle 2: A = 1/2 bh. But, this triangle requires you to cut in half. Doing this, that cuts your base as well. It will no longer be 30, by 15. For the left side of triangle 2, it will be A = 1/2 15 x 12, which you half either 15 or 12, where 12 is easier. Now it should be A = 15 x 6, which is 90. The right side of the triangle will be A = 1/2 15 (12) as well, which is also 90. In the end, you will add it together, which is 180.
P = a + b + c. So, you will add 15, 23, and 12 first. Then, add 15, 20, and 12. You should have 50 and 47, which you will add that together as well.
Triangle 3: I will keep working on this one, as I am a little unsure :/
Triangle 4: You will do the same steps for this triangle like you did on #2. Though the numbers you plug on are different. A = 1/2 bh - A = 1/2 10 x 14. (This is for the left side) You will have to half either the base or the height's number. So, it will be A= 5 x 14 or A=10 x 7. Then, you will multiply and find your answer (70). (This is for the right side) A = 1/2 10 x 14. Due to the numbers being the same, it can be shown that the area will also be 70. You then add 70 and 70 together.
P = a + b + c. You will add 10, 14, and 15 for the left side and 10, 14, and 17 for the right side. Once you add them separately, add the answers together (10+14+15 =39 and 10+14+17 = 41. 39 + 41 = 80.
Triangle 5: A=1/2 bh. A = 1/2 12 x 16. You will half either 12 or 16 (It does not matter). Then you should have A = 6 x 16 or A = 12 x 8. Either way, your answer is 96.
P = a + b + c. You will add 12, 16, and 18. This results in 46.
Hope this helps! I will continue to figure out Triangle 3

G) = 50.8cm
Step-by-step explanation:
For F, add the area of the rectangle (8*5 = 40) to the area of the half circle ((pi * 5^2)/2 = 39.27) to get the total (79.27)
For G, add the area of the square (5.5*5.5 = 30.25) to the area of the trapezoid (3 * (8.2+5.5)/2 = 20.55) to get the total (50.8)

Step-by-step explanation:
the interior sum of a triangle is 180 so add and subtract
63 + 49 = 112
180 - 112 = 68
Answer:
w = 68
Step-by-step explanation:
All angles add up to 180 so:
w + 63 + 49 = 180
w + 112 = 180
w = 180 - 112
w = 68
