Answer:
The first digit of the quotient should be placed at the leftmost place of the places of the all the digits in the quotient.This is so from the basic rule of division.
Step-by-step explanation:
The quotient is given by,
[where [x] is the greatest integer function on x]
= [322.6]
= 322
and the remainder is given by,

= 9
So, the first digit of the quotient should be placed at the leftmost place of the places of the all the digits in the quotient and this is so from the very basic rule of division.
Answer:
0.47 and 11.53
Step-by-step explanation:
h = 60t − 5t²
27 = 60t − 5t²
5t² − 60t + 27 = 0
Quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
t = [ -(-60) ± √((-60)² − 4(5)(27)) ] / 2(5)
t = (60 ± √3060) / 10
t = 0.47 or 11.53
Answer:
The answer is $2750. Which is the difference in the amount of interest Emma would have to pay for these two loans
Step-by-step explanation:
Interest=( P× r × t)/100
60 months is converted to 5years(60/12=5)
Interest= (25000 × 5 × 5) /100
= $6250
72months is converted to 6 years(72/12=6 Years)
Interest=( P× r × t)/100
= (25000 × 6 × 6)/100
=$ 9000
The difference in the interest= $9000- $6250
= $ 2750
(2/7)^2 x (7/9)^2
((2^2)/(7^2)) x ((7^2)/(9^2))
(4/49) x (49/81)
*Cross multiply*
(4/81)
