Answer:
B
Step-by-step explanation:
She could be either TN, CT, TS, CN, NS, or CS
Let's let x = the number of workers making $75 per day
Then that would mean (60 - x) would be the number of workers who make $100 per day.
Now the average salary, which needs to be 80, can be found by adding all the salaries of the 60 workers and dividing by 60. The following equation can model this problem:
[75x + 100(60 - x)]/60 = 80 simplify the left side of the equation
(-25x + 6000)/60 = 80 multiply both sides by 60
-25x + 6000 = 4800 subtract 6000 from both sides
-25x = -1200 divide both sides by -25
x = 48 recall we set 'x' to equal the number of workers making $75 per day
And there you have it! Hope this helps..
Answer:
A. x = 8.
B. x = 31.
C. x = 32.
Step-by-step explanation:
Here. the sum of the 2 parallel sides of the trapezoid = 2 * length of the middle line segment.
MN + RS = 2PQ
32+ x = 2*20
x = 40 - 32
x = 8.
MN + RS = 2PQ
20 + 42 = 2PQ
2x = 62
x = 31
MN + RS = 2PQ
22 + 42 = 2PQ
2x = 64
x = 32.
Answer: 188 months
Step-by-step explanation:
Principal = $129 000
Payment = $1000
Mortgage % = 5.15
Since,
Number of Months = log (1+[rate/(Payment/Principal)-rate] / log (1 + rate)
Also,
rate = 5.15/1,200 = 0.004292
Number of Months = log (1 + [0.004292/(1,000/129000) -0.004292] / log(1+0.004292)
Number of Months = log ( 1 + 0.004292/ ((0.007752 -0.004292) / log (1.004292)
Number of Months = log ( 1 + (0.004292/0.00346))/ log (1.004292)
Number of Months = log (1 + 1.240) / log (1.004292)
Number of Months = log (2.240) / log (1.004292)
Number of Months = 0.3502 / 0.001860
Number of Months = 188.28 months
Approximation to whole month,
Number of months = 188 Months.
