Answer:
138 pairs
Step-by-step explanation:
The number of blue pleated slacks is 5 times the number of gray pleated slacks, so:
(eq1)
The number of gray non-pleated is twice the number of blue non-pleated slacks, so:
(eq2)
The total number of blue slacks is 333, and the total number of gray slacks is 225, so we have that:
(eq3)
(eq4)
If we add (eq1) and (eq2), we have:
(eq5)
Using (eq3) and (eq4) in (eq5), we have:
From (eq1), we have:
From (eq3), we have:
Answer:
63.6mm
Step-by-step explanation:
According to cosine rule;
AB² = BC²+AC²-2(BC)(AC)cos m<C
Substitute the given values
AB² = 70²+40²-2(70)(40)cos 64
AB² = 4900+1600-5600cos64
AB² = 6500-5600(0.4384)
AB² = 6500-2,454.87
AB² = 4,045.12
AB = √4,045.12
AB = 63.6mm
Hence the length of AB is 63.6mm
<span>12.5% as a fraction in simplest form is 12 1/2
why?
12 is 12 whole so 12
.5 is half of a whole so 1/2 is .5 in simpliest (?how do u spell simpleist?)form
oh yeah in your question:)</span>
The answer is B. Because there are 8 ribbons in all. 1 ribbon is black. so the equation would be 1/8. Assuming you don't draw the black ribbon on the first try, then you would try again. The second time you draw a ribbon you don't put the ribbon you drew back in. That means there are only 7 ribbons the second time. The 1 black ribbon is still in the bag than the equation would be 1/7. Then you add the two together. So it would be 1/8 + 1/7 = 1/15. Remember to only add the bottom numbers. not the top ones unless they are different colors or objects.
