Answer:
1184
Step-by-step explanation:
Given :
No. of parts made by machine A in 10 minutes = 7
No. of parts made by machine A in 10*6 minutes (1 hour) = 7 * 6 = 42 parts
No. of parts made by machine A in 12 hours as
required in problem = 42 * 12 = 504
______________________________________________________
No. of parts made by machine B in 15 minutes = 17
No. of parts made by machine A in 15*4 =60 minutes (1 hour) = 17 * 4= 68 parts
No. of parts made by machine B in 10 hours as
required in problem = 68 * 10 = 680
______________________________________________________
There fore total no. of parts made by
machine A and machine B on Monday = 680 + 504 = 1184 (Answer)
Answer:
11 bracelets a day
Step-by-step explanation:
First term [ a ] = 6.3
Common difference [ d ] = 8.8 - 6.3 = 2.5
Using general term formula,

78.8 = 6.3 + (n-1)*2.5
2.5*(n-1) = 72.5 [ Dividing both sides by 2.5 ]
n-1 = 29
n = 30
Hence, 78.8 is the
30th term in the arithmetic series.
Answer: She invested $5000 in an account that pays 6% interest and $10000 in an account that pays 7% interest.
Step-by-step explanation:
Let P be the initial amount she invested in an account that pays 6% interest.
Then, amount invested in other account = 2P
Simple interest = Principal x rate x time
After one year, for the first account,
Interest = P(0.06)(1) = 0.06P
For second account,
Interest = (2P)(0.07)(1)=0.14P
Total interest = 

2P = 2(5000)=10000
Hence, She invested $5000 in an account that pays 6% interest and $10000 in an account that pays 7% interest.
