Identify the variation as direct, inverse, joint or combined. A = r²

myrzilka [38]

Answer : Direct Variation

Question :

Identify the variation as direct, inverse, joint or combined. A = $\pi r^2$

We know direct variation is y = kx

Where k is the constant of proportionality

When value of x increases then y also increases. when x value decreases then y value decreases.

The value of y depends on value of x It means y is directly proportional to x.

Hence A = $\pi r^2$ is a direct variation.

Compute<br><br> 8*4-4 divided by 2 +1

iragen [17]

Solution of 8 x 4 - 4 divided by 2 +1 is 9.33

<h3><u>Solution:</u></h3>

Given that,

8 x 4 - 4 divided by 2 +1

We have to compute the above equation

Let us write the given sentence mathematically:

$\rightarrow \frac{8 \times 4-4}{2 + 1}$

Let us BODMAS rule to solve the above expression

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.

So let us first perform multiplication of 8 and 4 in numerator

$\rightarrow \frac{32 - 4}{2 + 1}$

Now we can perform addition of 2 and 1 in denominator

$\rightarrow \frac{32-4}{3}$

Now we can perform subtraction of 4 from 32 in numerator

$\rightarrow \frac{28}{3}$

Now perform division of 28 by 3

$\rightarrow \frac{28}{3} = 9.33$

Thus solution of 8 x 4 - 4 divided by 2 +1 is 9.33

What is the math work you would do for this question?

Neko [114]

Oh my gosh I used to have that same workbook I HATED it. Anyways, the formular for volume is length x width x height, so for this rectangular prism you would multiply 4 2/5 x 10 x 3. Also it doesn’t matter which order you multiply because you should still have the same end result.

Hope this helps! If you need anymore answers from this book then ask me. My teacher made us do like 10 pages a day all school year.
