To multiply mix numbers and a normal fractions you make the mix number into a improper fraction. To do that you multiply the bottom and add the top. Here are the answers:
1/2 x 5 1/2 = 2 3/4
3 3/4 x 1/2 = 1 7/8
1/2 x 3 1/3 = 1 1/6
3/4 x 3 1/6 = 3 1/8
2/1 x 1 1/7 = 2 2/3
In problem number 1, the answer is 2. because if Aneesha multiply the first equation with 5, 2y will become 10y and if she multiply the sencond equation with 2, 5y will become 10y and 10y from both equations cancel out each other.
in problem number 2, the answer is 2. it's the same logic as number 1. if you multiply 0.5x with 2, it will become 1 and cancel out with x from first equation.
Average rate of change [1,3] = (15.882 - 11.38)/(3-1) = 4.502 /2 = 2.251
average rate of change [-4,-2] = (0.0971- 0.0018)/(-2+4) = 0.0953 /2 = 0.04765
average rate of change [1,3] / average rate of change [-4,-2]
= 2.251 / 0.04765
= 47.24
answer
47.24
Answer:
$1,075
Step-by-step explanation:
Simple Intereat Formula:
A = P(1+rt)
where A is the final amount,
P is the principal(original amount invested)
r = annual interest rate
t = time in years
Given P = 1000
r = 2.5/100
t = 3 (Beginning of 4th year means the 4th year is not counted)
A = 1000(1+(0.025)(3))
= 1000(1.075)
=$1,075
