Answer:
interest = Amount-Principal= 2160-2000=160
Rate = Interest*100/(P*T)= 160*100/(2000*2)=4%
Step-by-step explanation:
y=7x-5 This is the same as saying y-7x = -5 Well easy. You just make up numbers that make this work. Let x be 1 y-7=-5 y=-5+7 y=2 So one ordered pair is (1,2) Let x=2 y-14=-5 y=9 So another ordered pair is (2,9) Let x=3 y-21=-5 y=-5+21 y=16 So another ordered pair is (3,16)

V = 4/3(pi)(r^3)
V = 4/3(pi)(4.2^3)
V = 310 cm^3
Good luck!
Question:
I met a men who said if you can guess my age, i will pay you one dollar for each year that i have lived. I will also give you two hints. If you take my age and divide it by any odd number greater than 1 and less than 9 you will get a remainder of 1. But if you take my age and divide it by any even number greater than 1 and less than 9 you will not get a remainder of 1. how much money could you earn?
Answer:
The man's age is 106 years
Amount earned is $ 106.00
Step-by-step explanation:
Here we have
3 × a = Age +1
5 × b = Age +1
7 × c = Age +1
Age is even, therefore, a, b and c are odd numbers
Since 3, 5 and 7 are factors of Age + 1
Then, 3 × 5 × 7 is a factor. That is 3 × 5 × 7 = 105
Therefore, 105 + 1 or 106 is a possible solution as an even number divided by another even number will not have a remainder of 1.
The age of the man is 106 years
Therefore, the amount earned = $ 1.00/year × 160 years = $ 106.00
