Answer:
its the second one
Step-by-step explanation:
Answer:
1.8571428 hours
Step-by-step explanation:
Given that :
Price of stock A at 9 am = $12.53
Rate of increase = $0.12 per hour
Price of stock B at noon = $13.28
Rate of Decrease = $0.09 per hour
Let number of hours = x
Price of stock A at noon :12.53 + 0.12(3) = 12.89
12.89 + 0.12x = 13.28 - 0.09x
0.12x + 0.09x = 13.28 - 12.89
0.21x = 0.39
x = 0.39 / 0.21
x = 1.8571428
Hence the prices of the stock will be the at about 1.857 hours
For this one, use the order of operations to solve it, we called it PERMDAS to remember the steps.
14-6.2 times (-3+ -7)
So do the parenthesis first
-3+-7= -10
now the multiplication
-6.2 times -10= 62
a negative times a negative equal a 62
Now your problem is 14-62
Which equals -48.
So if I did my math and operations correctly, the answer would be B. -48.
Hope this helps!
All of them, so 10.
Check the key to see how to read it. 1 | 7 would be 17. So the number of pairs in each store are:
17, 18, 20, 25, 28, 34, 34 37, 38, and 40 (all below 60)
