Answer: 157.787 cubic cm

Step-by-step explanation:

Given: 8.3 cm

Assuming all sides are equal you have a LWH of 8.3 cubed. So 8.3 times 8.3 times 8.3

This gives you an area of 157.787 cm cubed round to the desired decimal or keep it if not directed otherwise.

What is the relation between the variables in the equation x^4/y=7?
makkiz [27]

Answer:

So, the relation between variables are

y=\frac{x^4}{7}

Step-by-step explanation:

We are given

\frac{x^4}{y}=7

Since, we have to find relation between variables

so, we can solve for y

\frac{x^4}{y}=7

Firstly, we will multiply both sides by y

\frac{x^4}{y}\times y=7\times y

we can simplify it

x^4=7\times y

we can isolate y

so, we can divide both sides by 7

so, we get

y=\frac{x^4}{7}

for the following two numbers, find two factors of the first number such that their product is the first number and their sum is
zepelin [54]
You can make some algebraic equations and solve it.
The first would be:
x \times y =  - 21
The second would be
x + y =  - 4
You can then rearrange the second into
x =  - 4 - y
And subsitute it into the first like so:
( - y - 4) \times y = -  21
After that, distribute the y into the parantheses.
{ - y}^{2}  - 4y =  - 21
Subtract the 21 on both sides and multiply by -1 on both sides:
{ - y}^{2}  - 4y  +  21 \\ {y}^{2}  + 4y  -  21
You then can factor it into:
(y + 3) \times (y - 7) = 0
With Zero Product Property, we can determine y to be either -3 and 7. Since the variables are interchangable, you can say the same about x, just that whatever x is, y must be the other value.


Thus, the answer is 7 and -3.

Help please on this math problem: The prices of backpacks at a store are 22, 16, 39, 35, 19, 34, 20, and 26. Find the Mean Absol
Ivanshal [37]
Answer: 7.22
(note: this is a result after rounding. The result before rounding was 7.21875)

========================================================

Explanation:

Given Set of Values = {22, 16, 39, 35, 19, 34, 20, 26}

Add up the values: 22+16+39+35+19+34+20+26 = 211
Divide that sum by 8 as there are 8 values: 211/8 = 26.375

The mean is 26.375

Now subtract the mean from each data value. Apply the absolute value to ensure the difference is never negative

|22 - 26.375| = 4.375
|16 - 26.375| = 10.375
|39 - 26.375| = 12.625
|35 - 26.375| = 8.625
|19 - 26.375| = 7.375
|34 - 26.375| = 7.625
|20 - 26.375| = 6.375
|26 - 26.375| = 0.375

Add up those results
4.375+10.375+12.625+8.625+7.375+7.625+6.375+0.375 = 57.75
Then divide by 8 
57.75/8 = 7.21875

The mean absolute deviation of the prices is 7.21875
Rounded to two decimal places, it is 7.22
Since we're talking about money, it makes sense to round to the nearest penny.

Solve the following: 4x-1/2 = x+7
MArishka [77]

Answer:

x = 2.5

Step-by-step explanation:

4x-1/2 = x+7

  4x-x = 7+0.5

     3x = 7.5

       x = 2.5
