Answer:
158m^3
Step-by-step explanation:
First, let's figure out the total amount of water in the tank.
It measures 4.5m by 6m by 8m. The volume of a rectangular prism is V=lwh.
Therefore, the volume is:
We are told is it filled to the brim, so we can conclude that there are 216 cubic meters of water in the tank.
We used 58 cubic meters of water, so we simply need to subtract that from 216:
There is still 158 cubic meters of water left in the tank.

Answer:
The linear equation for the line with an x-intercept at (-5,0) and y-intercept at (0,4) is found as .
Step-by-step explanation:
A condition is given that a line has an x- intercept at (-5,0) and y- intercept at (0,4).
It is asked to find a linear equation satisfying the given condition.
To do so, first determine the slope of the line using coordinates of the given intercepts. Then write the equation in the slope-intercept form using the slope and the y- intercept.
Step 1 of 2
Determine the slope of the line.
The points of the intercepts of the line are given as (-5,0) and (0,4). Next, the formula for the slope is given as,
Substitute 4&0 for and
respectively, and 0&-5 for
and
respectively in the above formula. Then simplify to get the slope as follows,
Step 2 of 2
Write the equation in the slope-intercept form.
The slope-intercept form of a line is given as follows,
The coordinates at the y- intercept is (0,4). Now, as the y- coordinate is 4 , so b=4.
So, substitute 4 for b and for m in the equation y=mx+b, as follows,
This is the required linear equation.
