Answer:

The surface area is 148

Step-by-step explanation:

Soooo i had to look up how to do it cause i completely forgot how. But once i did, i worked it out.

The formula i got was: A= 2(wl+hl+hw)

W= width h= height l= length

From there i just replaced the corresponding numbers for the letters that represent them. (think of that as like you see someone that you think represents you and you try to replace them, with you. Same here just w/ numbers and letters)

A= 2 [ (4x5) + (6x5) + (6x4) ]

from here you do order of operations starting with what's inside the parentheses. Then you work your way out.

A= 2 [20+ 30+ 24]

A= 2 [74]

Anytime a number is next to parentheses or brackets (which are these: [ ] ) you multiply what is outside them by what's inside them. (for this think about kids. When you seperate them, they try to make more noise. When you seperate numbers, they multiply)

Final answer is

A= 148

if this is wrong i am so, so, so sorry. I hope this helps, and i hope you have an amazing day!! Be tiger fierce! :)

A length of 5.3, a width of 7, and a height of 3. This would give you the same surface area of 148 as the 1st one. Good luck with your studies <3

So 4a=0.24 well its simple
your gonna divide 4 on both sides the 4 crosses out and 0.24 divided by 4 equals 0.06 or just .06 does that make sense?

May someone please help me on which to graph?

Answer:

Option (4)

Step-by-step explanation:

Proportional relationship means,

y ∝ x

y = kx

$k=\frac{y}{x}$

Here, k = proportionality constant

Therefore, if the graph of a line passes through the origin (0, 0) table will represent the proportional relationship.

From table 1,

For a point (1, 2)

$k=\frac{2}{1}=2$

For another point (3, 2)

$k=\frac{3}{2}=1.5$

In both the cases 'k' is not same of constant.

Therefore, table (1) is not proportional.

For table (2),

Line passes through (2, 0).

That means there is a x-intercept → (2, 0)

Therefore, table doesn't represent a proportional relationship.

For table (3),

Line passes through a point (0, 1)

It means given line has a y-intercept → y = 1

Therefore, table doesn't represent a proportional relationship.

For table (4),

Line of this table passes through two points (1, 3) and (2, 6)

$k=\frac{3}{1}=3$

$k=\frac{6}{2}=3$

Therefore, proportionality constant for the given table is 3.

Now we can graph table (4).

What is the mean absolute deviation and what does it tell you about data sets?

dmitriy555 [2]

The mean absolute deviation is the average of the average. It shows the average distance of the numbers in a data set from the mean. After finding the mean, you find the absolute value of the distance between each number, and find the mean of those numbers to find the mean absolute deviation.
