Answer:
He can cook 52 or less than 52 batches of lasagna.
Step-by-step explanation:
0.9L+0.3S≤60
Putting the value of s = 44
0.9L+0.3 (44) ≤ 60
0.9L+ 13.2 ≤ 60
0.9L ≤ 60 -13.2
L ≤ 46.8/0.9
L ≤ 52
Dj kay-cee: 50x+100
Dj fav fred: 30x+150
So, setting up the equation, you get that 50x+100=30x+150
So, 20x=50, and x=
So after 2.5 hours, dj kay-kee and dj fab fred would charge the same amount.
Answer:
The answer in the procedure
Step-by-step explanation:
Let
A1 ------> the area of the first square painting
A2 ----> the area of the second square painting
D -----> the difference of the areas
we have


case 1) The area of the second square painting is greater than the area of the first square painting
The difference of the area of the paintings is equal to subtract the area of the first square painting from the area of the second square painting
D=A2-A1


case 2) The area of the first square painting is greater than the area of the second square painting
The difference of the area of the paintings is equal to subtract the area of the second square painting from the area of the first square painting
D=A1-A2

Answer:</h2>
The average speed of car is:
0.75 miles per minutes.
The equation of line is:

<h2>
Step-by-step solution:</h2>
The table that describes the time and number of miles marked is given by:
Time Miles
0 0
4 3
8 6
Clearly we could observe that with the increase in time by every 4 minutes the number of mile increases by 3.
i.e. the average speed is calculated as the ratio of change in miles to the change in time.
Hence,

Hence, the average speed=0.75 miles per minutes.
Also we will find the equation of the lines that related the miles and time by using the two-point formula.
i.e. any line passing through (a,b) and (c,d) is calculated by using the formula:

Here (a,b)=(0,0) and (c,d)=(4,3)
i.e. the equation is given by:
