$\pi$ Answer:

the volume is 5.96

Step-by-step explanation:

$v =\frac{4}{3} \pi r^3\\\\$

9/8 as a decimal is 1.13

$\frac{4}{3}$ × $\pi$ ×1.13³≈5.96412

Hope this helps:).......if not then sorry for wasting your time and may God bless you:)

If three times a number added to 8 is divided by the number plus 7, the result is four thirds. Find the number.

Marina86 [1]

9514 1404 393

Answer:

4/5

Step-by-step explanation:

The wording is ambiguous, as it often is when math expressions are described in English. We assume you intend ...

$\dfrac{3n+8}{n+7}=\dfrac{4}{3}\\\\3(3n+8)=4(n+7)\qquad\text{multiply by $3(n+7)$}\\\\9n+24=4n+28\qquad\text{eliminate parentheses}\\\\5n=4\qquad\text{subtract $4n+24$}\\\\\boxed{n=\dfrac{4}{5}}\qquad\text{divide by 5}$

The number is 4/5.

What are the determinants for solving this linear system? 5x + 3y = 17 −8x − 3y = 9 |A| = |Ax| = |Ay| =

valentina_108 [34]

For this case we have the following system of equations:

$5x + 3y = 17\\-8x - 3y = 9$

We can Rewrite the system of equations of the form:

$Ax = b$

Where,

A: coefficient matrix

x: incognita vector

b: vector solution

We have then:

$A=\left[\begin{array}{ccc}5&3\\-8&-3\end{array}\right]$

$x=\left[\begin{array}{ccc}x\\y\end{array}\right]$

$b=\left[\begin{array}{ccc}17\\9\end{array}\right]$

Then, the determinant of matrix A is given by:

$|A|=(5)(-3)-(3)(-8)\\$

$|A|=-15+24$

$|A|=9$

Answer:

The determinants for solving this linear system are:

$|A|=9$
