Answer:

x + 14 \leq 20, x = 6 ton

Step-by-step explanation:

The truck can be filled with a total of 20 ton.

There are already 14 ton inside the truck, so if we call x the weight of goods that we can still add into the truck, we know that (x+14) must be equal at most at 20. Therefore, the inequality becomes:

x+14\leq 20

Solving it, we find

x\leq 6

which means that the most amount of goods that could be added to the truck is 6 tons.

7/3+3(2/3−1/3)*2 I need an answer to this question really quick, and by the way the two in the end is a second power
sweet-ann [11.9K]

Answer:

\frac{8}{3}

Step-by-step explanation:

Given

\frac{7}{3} + 3(\frac{2}{3} - \frac{1}{3} )²

= \frac{7}{3} + 3 (\frac{1}{3} )²

= \frac{7}{3} + 3 × \frac{1}{9}

= \frac{7}{3} + \frac{1}{3}

= \frac{8}{3}

Create a six sided cube that shows examples of different solids and explain how to calculate the surface area and volume of each
gulaghasi [49]
We are given a six-sided cube. To determine the surface area and the volume of the cube, we need to know the area of one side:

All sides of the cube are squares with side, s. The area of one square is

A = s^2 

The surface area of a cube is the sum of all areas of the sides. So

SA = 6 sides * s^2
SA = 6s^2

The volume of the cube is 

V = s^3

The volume of the cube represents the total solid area of the cube which includes the space inside the solid.

How many significant digits are there in 17.0
svet-max [94.6K]
The answer is three significant figures. The 1 and the 7 are both significant, because they are non-zero quantities.
This is where significant figures gets a little more complicated, because if a zero is used as a placeholder (i.e. 0.00027 cm) then it is insignificant.
But in the case above, the zero isn't being used as a placeholder, and thus, is significant.

Find the? inverse, if it? exists, for the given matrix.<br><br> [4 3]<br><br> [3 6]
True [87]

Answer:

Therefore, the inverse of given matrix is

=\begin{pmatrix}\frac{2}{5}&-\frac{1}{5}\\ -\frac{1}{5}&\frac{4}{15}\end{pmatrix}

Step-by-step explanation:

The inverse of a square matrix A is A^{-1} such that

A A^{-1}=I where I is the identity matrix.

Consider, A = \left[\begin{array}{ccc}4&3\\3&6\end{array}\right]

\mathrm{Matrix\:can\:only\:be\:inverted\:if\:it\:is\:non-singular,\:that\:is:}

\det \begin{pmatrix}4&3 \\3&6\end{pmatrix}\ne 0

\mathrm{Find\:2x2\:matrix\:inverse\:according\:to\:the\:formula}:\quad \begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}^{-1}=\frac{1}{\det \begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}}\begin{pmatrix}d\:&\:-b\:\\ -c\:&\:a\:\end{pmatrix}

=\frac{1}{\det \begin{pmatrix}4&3\\ 3&6\end{pmatrix}}\begin{pmatrix}6&-3\\ -3&4\end{pmatrix}

\mathrm{Find\:the\:matrix\:determinant\:according\:to\:formula}:\quad \det \begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}\:=\:ad-bc

4\cdot \:6-3\cdot \:3=15

=\frac{1}{15}\begin{pmatrix}6&-3\\ -3&4\end{pmatrix}

=\begin{pmatrix}\frac{2}{5}&-\frac{1}{5}\\ -\frac{1}{5}&\frac{4}{15}\end{pmatrix}

Therefore, the inverse of given matrix is

=\begin{pmatrix}\frac{2}{5}&-\frac{1}{5}\\ -\frac{1}{5}&\frac{4}{15}\end{pmatrix}
