I NEED HELP FAST PLEASE! Find the surface area of the following composite figure.
the answer is 228 I was wrong when I said
I think the choices is wrong
Answer:
B. 228 meters square
Step-by-step explanation:
6 x 4 = 24
24 x 4 = 96
6 x 6 = 36
(8 x 6) / 2 = 24
24 x 4 = 96
96 + 96 + 36 = 228 square meters

Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.
Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.
Answer:
The representation of Brian's situation in slope intercept form is:
y= 15x +70
Step-by-step explanation:
Let x be the number of weeks Brian started his collection.
y be the number of cards Brian has at present.
y= 45+25+ 15 x
or, y= 15 x +70
which is in the form of,
y= mx +c (slope intercept form)
where,
m= slope
x= x- intercept
c= constant.

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 .

Find the perimeter and the area of the polygon with the given vertices.
A (12,2), B (12,13), C (15,13), D (15,2)
The perimeter is __ units.
The area is __ square units.
Answer:
Step-by-step explanation:
As points A and B have same x-coordinate, length of AB will be given by the difference of y-coordinate
AB = 13 - 2 = 11 units
As points C and D have same x-coordinate, length of CD will be given by the difference of y-coordinate
CD = 13 - 2 = 11 units
As points B and C have same y-coordinate, length of BC will be given by the difference of x-coordinate
BC = 15 - 12 = 3 units
As points A and D have same y-coordinate, length of AD will be given by the difference of x-coordinate
AD = 15- 12 = 3 units
AB = CD = 11 units
BC = AD = 3 units
So,ABCD is a rectangle
Area = 11 * 3 = 33 square units
Perimeter = 11+11+3+3 = 28 units
Answer:
Solution :-At first
Length of AB = 13 - 2 = 11 cm
Length of CD = 13 - 2 = 11 cm
Length of BC = 15 - 12 = 3 cm
Length of AD = 15 - 12 = 3 cm
Now
Perimeter = 11 + 11 + 3 + 3
Perimeter = 22 + 6
Perimeter = 28
Area = 11 × 33 = 33 cm

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

Answer:
F) = 79.27cm
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)

While walking to the gym, Marie decides to play a game using a her lucky fair
six-sided die (which she carries with her all the time). Tossing an even number would
indicate walking forward that many steps and, likewise, tossing an odd number would
mean walking backwards that many steps (i.e. if she tosses a 3, she walks backward 3
steps). If the probability that after 2 rolls of the die, she is further away from the gym
that she was at the beginning of the game, can be represented as m/n
for m and n being relatively prime positive integers, find m^2 + n^2 ?
Answer:
i think that every time she rolls the dice, she is further away from the gym

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.

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.
