Can someone just explain the formula for the surface area of a 3-D rectangle (I do not know the official name)? Please explain it step by step.
Answers
Answer:
rectangular prism Area = 2L(W) + 2L(H) + 2W(H)
Step-by-step explanation:
Step 1 recognise the shape and unit ie) inches. cm etc.
Rectangular prism is like a cube but the length or height etc is disproportionate and therefore rectangular.and not cubic. even though its measured in cubic for volume and squared for surface area, it is added together each side square to allow for coverage.
Step 2
Count the sides you should automatically know how many sides for area
Full surface Area = how many sides
= 6
We then realise there is symmetry so we can multiply in pairs.
For spheres we multiply in 4;s Surface area = 4 π r2
Step 3
Know we have pairs how mnay pairs = 3
2L(w) + 2 L(h) + 2 W(h) = Surface area of rectangular prism
Show the multiplication and seperate with + sign
Step 4 Then add them all up and show unit square ^2 at end.
Answer:
SA=2lw+2lh+2hw
Step-by-step explanation:
To find the surface area of a cuboid or a rectangular prism, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Answer:
16250/3 or 5416.6666...
Step-by-step explanation:
((5)^2 +(7)^0) * (5^3)/(5/3)^-1
Step 1: You need to solve the numbers in the brackets first.
(5)^2 = 25 You do 5*5=25
(7)^0 = 1 Every number to the power 0 is equal to 1
(5^3) = 125 You do 5*5*5=25*5=125
(5/3)^-1 = (3/5) Since it is a fraction to the negative power, to remove the negative you do the reciprocal of the fraction which is putting the denominator as the numerator and the numerator as the denominator. Then you are left with (3/5)^1 and every number to the power one is that number.
Now we are left with (25+1) * 125/(3/5)
We still have (25+1)=26 We don't solve the (3/5) because the brackets is there to show that 26*125 is being divided by the fraction 3/5 not being divided by 3 then 5.
So with all the brackets solved
Step 2: Now you do the multiplication
26*125/(3/5)
26*125=3250 You get 26*125 as it is the only multiplication.
Now we are left with 3250/(3/5)
Step 3: You solve the division
3250/(3/5) When you have a number divided by a fraction you
=3250*(5/3) must change it to multiplication by doing the reciprocal
=16250/3 of the fraction (defined in step 1) and change from doing
or division to multiplication. Then you multiply the = 5416.66... numerators (3250*5=16250) and you are left with 16250/3.
If you want it in decimals you divide the numerator to the denominator 16250/3=5416.66...

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

( Will give 20 points! )Which ordered pair is a solution to the equation y = –3x – 5? A. (0, 0) B. (–1, 8) C. (1, –2) D. (1,-8)
Answers
Answer:
D
Step-by-step explanation:
to find which ordered pair is a solution to the equation.
substitute the x- coordinate into the right side of the equation and if the value obtained is equal to the y- coordinate then the ordered pair is a solution.
A (0, 0 )
y = - 3(0) - 5 = 0 - 5 = - 5 ≠ 0 ← not a solution
B (- 1, 8 )
y = - 3(- 1) - 5 = 3 - 5 = - 2 ≠ 8 ← not a solution
C (1, - 2 )
y = - 3(1) - 5 = - 3 - 5 = - 8 ≠ - 2 ← not a solution
D (1, - 8 )
y = - 3(1) - 5 = - 3 - 5 = - 8 ← solution
then (1, - 8 ) is a solution to the equation
Answer:
D. (1, -8)
Step-by-step explanation:
Given: y = -3x - 5
Using substitution, we can substitute the given value of coordinates into the equation to see which coordinate makes a true statement.
A. (0, 0)
0 = -3(0) - 5
0 = -5
This is a false statement.
B. (-1, 8)
8 = -3(-1) - 5
8 = 3 - 5
8 = -2
This is a false statement.
C. (1, -2)
-2 = -3(1) - 5
-2 = -3 - 5
-2 = -8
This is a false statement.
D. (1, -8)
-8 = -3(1) - 5
-8 = -3 - 5
-8 = -8
This is a true statement.
Therefore, the correct answer is D.

Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.
