Answer:
4 tribes. I don't even know how to do this question at all since it's way too difficult for me but this is an attempt.
Step-by-step explanation:
Let's use negative terms.
-2 = 6
-1 = 5
0 = 4
1 = 3
2 = 2
3 = 1
4 = 0
Answer:
Amount invested that yielded interest of 5% is $15000 and amount invested that yielded interest of 8% is $5000
Step-by-step explanation:
Johnny invested $20,000
We are told that it consisted of 2 portions because one returned an interest of 5% and the other one 8%
Now, Let x be the amount invested that earned 5% and y be the amount invested that earned 8%
Thus:
x + y = 20000 - - - (eq 1)
The total interest earned on the investment was $1150
Thus;
5%x + 8%y = 1150
This can be rewritten as;
0.05x + 0.08y = 1150 - - -(eq 2)
From eq 1, let's make x the subject.
x = 20000 - y
Putting 20000 - y for x in eq 2 gives;
0.05(20000 - y) + 0.08y = 1150
1000 - 0.05y + 0.08y = 1150
Rearranging, we have;
0.03y = 1150 - 1000
0.03y = 150
y = 150/0.03
y = 5000
Thus,
x = 20000 - 5000
x = 15000
Thus,
Amount invested that yielded 5% is $15000 and amount invested that yielded 8% is $5000
First restaurant price: 29 + 6l = x
x = final cost
l = kilo of lobster
Second restaurant price: 41 + 3l = x
We want them to be the same price, so: 29 + 6l = 41 + 3l
Subtract 3l from each side
29 + 3l = 41
Subtract 29 from both sides
3l = 12
Divide both sides by 3
l = 4
So, if she buys 4 kilograms of lobster from either place, it will cost the same.
It would cost $53.
Answer: 37.68 feet.
Step-by-step explanation:
To find the diameter of a circle, use the equation:
C = 2 * pi * r, where r is the radius of the circle.
The diameter is 12 feet, and the radius is 6 feet.
C = 12 * pi
C = 37.68 feet.
