Answer:
There are 96 large tents and 60 small tents
Step-by-step explanation:
Here, we want to calculate the number of tents of each sizes there
Let the number of 6-boys tent be s and the number of 4-boys tent be f
6s + 4f = 816 ••••••(i)
Ratio of large to small ( ratio of s to f)
8:5 = s/f
8/5 = s/f
8f = 5s
f = 5s/8 ••••(ii)
Substitute ii into i
6s + 4(5s/8) = 816
6s + 5s/2 = 816
Multiply through by 2
12s + 5s = 1,632
17s = 1632
s = 1632/17
s = 96
f = 5s/8
f = (5 * 96)/8 = 60
Answer:
- Only compound interest has an exponent in its formula.
- Simple interest is only earned on the original principal investment.
- Compound interest is earned on principal and interest.
Step-by-step explanation:
The above statements are self-explanatory.
__
The one statement that can be argued is ...
"Compound interest earns more money than simple interest at the same rate for the same amount of time."
This is true for time periods <em>longer than the initial compounding interval</em>. If interest is compounded annually, the amount of simple interest and compound interest <em>will be the same for the first year</em>. After that, the compound interest account earns more, because interest is paid on interest and principal, not just principal.
Answer:
see below
Step-by-step explanation:
19-3 will be greater
We are multiplying 1/2 *(19-3) which is multiplying by a number less than 1 it will be less than 1
18-3 = 16
1/2 * (19-3)
Using PEMDAS
We do parentheses first
1/2 ( 16)
Then multiply
8
Solution
In order to find greatest to least number, we have to convert the given fractions into decimals.
3 
% = 3 + 1/10 = 3 + 0.10 = 3.10%
3 
% = 3 + 2/5 = 3 + 0.40 = 3.40%
3 
%= 3 + 0.25 = 3.25%
3 
% = 3 + 0.33 = 3.33%
Now we can easily, compare the numbers and write from greatest to least.
3.40%, 3.33%, 3.25%, 3.10%
Greatest to least = 3 2/5%, 3 1/3%3, 3 1/4%, 1/10%,
Thank you :)
Johnny now has 90 so Jeana did not take 25 she only took 10
