Answer:
<h2> 52 chickens</h2>
Step-by-step explanation:
Step one:'
given
we are told that the total number of animals is 169
the ratio of horses to chickens= 9:4
total ratio= 13
Required:
number of chickens
Applying part to all principle, let the number of chickens be x
4/13=x/169
cross multiply
4*169=13*x
divide both sides by 13
x=4*169/13
x=676/13
x=52
There are 52 chickens
Answer:
5.19%
Step-by-step explanation:
The amount of an account (A) earning simple interest rate r for time t on principal P is ...
A = P(1 +rt)
Filling in the given values and solving for r gives ...
6000 = 5500(1 +r(21/12))
12/11 = 1 + r(7/4) . . . . . . . . . . divide by 5500, simplify fractions
1/11 = r(7/4) . . . . . . . . subtract 1
4/77 = r . . . . . . . . . . . multiply by 4/7
r ≈ 0.051948 ≈ 5.19%
You will be earning about 5.19% annual simple interest.
16. It depends on the signs that they have.
17. <em>a) </em>When adding two integers with the same sign, the sign stays the same and we just add up the numbers.
<em>b) </em>When adding two integers with different signs, we look which integer is bigger, then we pick its sign and subtract the smaller integer from the bigger integer.
Given the percentage taken off and the reduced price, the original price of the item is $142.
<h3>What was the original price of the item?</h3>
Given the data in the question;
- Percentage off the item = 20%
- Reduced price of the item = $113.60
- Original price of the item = ?
The original price of the item is at 100%, if the 20% is taken off. The price is now at 80%.
Hence 80% of the original price will give the reduced price.
Let the original price be represented by x
80% × x = $113.60
We solve for x
80/100 × x = $113.60
80x/100 = $113.60
Cross multiply
80x = $11360
x = $11360/80
x = $142
Given the percentage taken off and the reduced price, the original price of the item is $142.
