Answer:
if you draw LMN in the first quadrant, you need to draw L'M'N' in the third quadrant using the same coordinates as LMN but in the negative form.
The line you draw trough L and L' and both other two lines all go through the origin.
ANSWER
Find out the how many pounds of nickel have to be used to create alloy that contains 4.9 lb of zinc.
To proof
As given
An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.
the total part of the alloy are 18.
assuming one part be x.
thus
nickel part = 2x
zinc part = 7x
copper part = 9x
alloy that contains 4.9 lb of zinc.
than the equation becomes
7x = 4.9
x = 0.7
Therefore
nickel part = 2x
= 2× 0.7
= 1.4 lb
1.4 lb of nickel have to be used to create alloy that contains 4.9 lb of zinc.
Hence proved

Answer:
<u>We need to buy 3 cases of juice.</u>
Correct statement and question:
No. of diners = 240 Portions of juice served = 4 oz. per diner Size of juice can = 48 oz. How many cases of juice required if there are 8 cans in a case and you must buy a whole case?
Source:
Previous question that you can search at brainly
Step-by-step explanation:
Let's calculate the number of cases of juice are required this way:
Number of cases required = [(Number of dinners * portion of juice served)/Size of juice can]/Cans in a case
Replacing with the real values, we have:
Number of cases required = [(240 * 4)/48]/8
Number of cases required = [(960)/48]/8
Number of cases required = 20/8
Number of cases required = 2.5
<u>But let's remember that we must buy only whole cases, then we need to buy 3 cases of juice.</u>
