The 15 lbs at $7=$105
So multiple 5x9 as a test and check results. 105-45=60
Here you can see that 60 is a factor of 6 by 10 so you got lucky and got the answer of 10lbs at $6 & 5lbs at $9=15 lbs at $7 average
1/4 - 1/6 = (6-4)/24 = 2/24 = 1/12
1/3 - 1/4 = (4-3)/12 = 1/12
Answer:
r ≥ -1. it is A because r is greater than or equal to -1.
I am sorry <u>if</u> I got it wrong.
Step-by-step explanation:
3r+2(12r+7) ≤ 5r-8
27r+14 ≤ 5r-8
I subtract 27r and 5r.
22r+14 ≤ -8
I subtract 14 and -8.
22r ≤ -22
Divide 22 on both side.
r ≥ -1
The answer is 4,800 . You have to multiply 120 and 40.
Answer:
<h2>
1.14%</h2>
Step by step explanation
Step one:
The total pieced produces is 2374
total defective is 27
to find the percentage of the defective pieces, we would need to divide the total pieces of the defective by the total number of pieces produced by the machine and multiply the result by 100
Step two
% defecive= (27/2374)*100
% defecive= 0.0113*100
% defecive= 1.137%
<u>To the nearest hundredth of a percent 1.14%</u>
