For the first one, they got rid of the 6x when they shouldn’t have, and the correct answer is x = 21.5
For the second one, 47 would be subtracted by 180, not 90, and the correct answer is 133
For the third one, 5x - 10 doesn’t equal 115, 5x - 10 equals 180 - 115, and the correct answer is x = 17
Answer:
Rs 937.50
Step-by-step explanation:
Rs 750 for 4 years at 6 1/4% interest:
Simple interest is found using i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the number of years.
Here, i = (Rs 750)*0.0625*4 = Rs 187.50
The amount (that is, principal plus simple interest) will be:
Rs 750 + Rs 187.50 = Rs 937.50
The way to do it can be explained like this:
Say AB and CD are the two parallel lines cut by a transversal at E and F respectively.
Then the pairs of alternate interior angles are:
Angle(AEF) and Angle(DFE)
Angle(CFE) and Angle(BEF)
Now lets prove if this is true:
<span>Angle(CFE) +Angle(DFE) = 180
(linear pair)
Also
Angle(CFE) +Angle(AEF) = 180
(Corresponding angles)
</span><span>Equate the above results:
Angle(CFE) +Angle(DFE) = Angle(CFE) +Angle(AEF)
</span><span>Angle(DFE) = Angle(AEF)
</span>Happens the same with
<span>Angle(CFE) = Angle(BEF)
</span>Hope this is very useful for you
Answer:
The answer is that she would pay $65.56 in finance charges at the end of the month.
Step-by-step explanation:
Given: APR = 19.99%
Carry Over Balance: $398.97
The APR or Annual Percentage Rate, is calculated daily. You will need to get the daily periodic rate, or DPR, so divide the APR by 365:
19.99% = .1999
.1999 / 365 = .005477 (This is the Approximate DPR, rounded up to .005477)
To get the finance charge, multiply the average daily balance by the DPR and then by 30 days:
398.97 * .005477 * 30 = $65.56 finance charge for this carry over balance, at the end of the month. This assumes that the balance is the average daily balance.
Hope this helps!! Have a great day!
Answer:
Step-by-step explanation:
If diameter is 14 inches radius = d/2 = 14/2 = 7 inches
Circumference = 2 pi R = 2 × 22/7 × 7
= 44 inches
Area = pi R square = 22/7 × (7)^2
=22/7 × 49
= 154 inches
Hope this helps
