To do it without a calculator:
10% of 67 is 6.7
6.7 x 8 is 53.6 (80%)
1% of 67 is .67
53.6 - .67 is 52.93 (79%)
Answer:
R300
Step-by-step explanation:
<u>To solve:</u>
- Multiply 25 by 6 to represent the earnings of a shift.
- Multiply the shift earnings by 2 to represent how much he earned over the weekend.
<u>Multiply</u><u> </u><u>25 by 6:</u>
<u>Multiply 150 by 2:</u>
<u>
</u>
Joe will earn R300 over the weekend,
The width would be 236 and the lengths would be 118
Use the equations 2L+W=472 and W*L=MAX
Change the first equation to W=472-2L and plug this into the other equation
(472-2L)(L)=MAX
472L-2L^2=M (take derivative)
472-4L=0 (set to 0 to find the max value)
4L=472
L=118
Plug into original to get W=236
Hope this helps!
Answer:
(50000000 ≤ P ≤ 90000000)
Step-by-step explanation:
The chart represents annual profits in millions of dollars. From the chart, the least annual profit is 50 million dollars and that was is the year 2009.
The highest annual profit is 90 million dollars and that was is the year 2012.
The compound inequality representing the annual profits P(in millions or dollars) from 2006 to 2013 would be
(50000000 ≤ P ≤ 90000000)
