Letter D
A = 135°
B = 30°
cosAcosB - sinAsinB = cos(A+B)
cos(135°+30°)
cos(165°)
Try this option:
only the 1-st way, where 25x+40x=x(25+40)... =260.
Another way to calculate it is 25*4+40*4=100+160=260.
answer: way 1.
Answer:
$613.04
Step-by-step explanation:
<em>Compound Interest Formula:</em>
n = number of compounds
t = time
r = interest rate
P = principle amount (original amount)
A = final amount
Since it's compounded quarterly, that means there will be 4 compounds per year, so n=4. The interest rate has to be converted to the decimal value, and this is done by simply dividing it by 100 to get r=0.06.

Answer:
the answer is $62,500
Step-by-step explanation:
1. you first multiply $25 by 85 people
2. you multiply the answer by 52 weeks
3. then subtract 48,000 sa the labor
1. $25×85=2,125
2. ans×52=110,500
3. ans-48,000=62,500
