The amount of interest he would earn in one (1) year is equal to $80.
<u>Given the following data:</u>
- Interest rate = 10% = 0.1
To determine how much interest he would earn in one (1) year:
<h3>How to calculate
simple interest</h3>
Mathematically, simple interest is given by this formula:
<u>Where:</u>
- S.I is the simple interest.
- P is the principal or starting amount.
- T is the time measured in years.
Substituting the given parameters into the formula, we have;
Simple interest = $80

Answer:
1/4 of a dollar
Step-by-step explanation:
25x4=100
I see from the given data that each additional carpet after the first costs $50 each to have cleaned.
The first costs $125. Supposing we subtract $50 from that, we get $75. So, it sounds like it costs $75 just to get the carpet cleaners to your house.
The rule would then be $75 + $50x, where x : {1, 2, 3, 4, .... }
Let's check this result. Suppose x = 1. Will the charge be $125, as show in the table? $75 + $50(1) = $125. Correct.
Suppose x = 4. Will the charge be $275 as shown in the table?
$75 + $50(4) = $275. YES
Answer:
approximately 7 hours
see the explanation
Step-by-step explanation:
The picture of the question in the attached figure
Let
x ----> the time worked in hours
y ----> the amount earning in dollars
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
so
In this problem we have a proportional relationship
step 1
Find approximately how many hours would it take Delia to earn $250 ?
Looking at the graph
For y=$250 The value of x is approximately 7 hours
see the attached figure N 2
step 2
Find the exact value
from the graph take the point (5,175)
Find the value of k
----> 
The linear equation is
For y=$250
substitute
solve for x
Megabyte is equal to 1 million bytes, while kilobyte is equal to 1000 bytes.
Divide 1,000,000 with 1,000
1000000/1000 = 1000
There are 1000 kilobytes in 1 megabyte.
hope this helps
