Because the ones place is under 5, we round down, and 392 becomes 390 when rounded to the nearest 10
Answer:
(C) 2
Step-by-step explanation:
Given equations 2a + 7b+2c=16 and 2a + 3b +2c= 8, you want to know the value of b.
<h3>Solution</h3>
The coefficients of 'a' and 'c' are the same in the two equations, so we can eliminate those variables by subtracting one equation from the other. We can keep the resulting coefficient of 'b' positive if we subtract the second equation from the first.
(2a +7b +2c) -(2a +3b +2c) = (16) -(8)
4b = 8 . . . . . . . simplify
b = 2 . . . . . . . divide by 4
Answer:
$297.41
Step-by-step explanation:
Given that:
Amount = 9270
Derferred period = 6 months = 0.5 yr
Rate = 17.95% = 0.1795
Amount = 9270(1 + 0.1795)^0.5
Amount = 9270(1.1795)^0.5
Amount = 10067.663
PV = 10067.663
Number of months, n = 48
Monthly amount to be paid :
rp = rate per period = 0.1795/12 = 0.0149583
(rp * PV) / 1 - (1 + rp)^-n
(0.0149583 * 10067.663) / 1 - (1 + 0.0149583)^-48
150.5951234529 / 0.5096723
= 295.47441
Closest option is $297.41
A/B is a reduced fraction which can be represented as a
terminating decimal if and only b is of the form 2^n5^n where m and n are non
negative integers. For example: 7/250, the terminating decimal here is 0.028 as
250 as the denominator equals to 2*5^2.
According to the above, we must know whether the denominator
have only 2-s and or 5-s as the prime factors. So,
Q = 8 = 2 ^3 = hence the denominator has only 2 prime
factors. Fraction P/Q will be termed as terminated decimal which is sufficient.
