Step-by-step explanation:
volume of cube=l³
=(11)³
=1331m³
volume of cuboid=l*b*h
=11*8*4
=352m³
Answer:
Part a) 
Part b) 
Step-by-step explanation:
Part a) Write an equation for T (d)
Let
d ----> the number of days
T ---> the time in minutes of the treadmill
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
The slope or unit rate is

The y-intercept or initial value is

substitute

Part b) Find T (6), the minutes he will spend on the treadmill on day 6
For d=6
substitute in the equation and solve for T


I believe 10c-4d would be your answer
Answer:
<h2>x=33 and y=12 7/11</h2>
Step-by-step explanation:
<h2> soln</h2><h2> ( 4x-3)+41=180</h2><h2> 4x+38=180</h2><h2>4x=180-38</h2><h2> 4x=142 </h2><h2>divide 4 both side with make value of x</h2><h2>x=33</h2>
<h2> and value of y is</h2><h2> soln </h2><h2>11y+6+45=180</h2><h2>11y+51=180</h2><h2>11y=180-51</h2><h2>11y=129</h2><h2>divide 11 both side with make value of y</h2><h2> y=12 7/11 this is my answer</h2>
