Which graph shows that Cindy reads about 3/4 of the time while riding in the car?
1 answer:
The graph that shows a unit rate of 3/4, which is the time Cindy reads while riding in the car is the graph attached below.
<h3>What is Unit Rate?</h3>Unit rate can be described as a constant or exactly how much of one quantity is per 1 unit of another quantity.
Unite rate (k) = x/y.
In the graph attached below, when x (hours driving) = 3, y (hours reading) = 4.
Therefore, unit rate = 3/4. We can then conclude that the graph that shows that Cindy reads 3/4 of the time she rides in a car is the graph attached below.

Answer:
base = e
Step-by-step explanation:
The general log function is defined as
.... (1)
where, a is the base of the log function.
The natural logarithm function is
It can be rewritten as
.... (2)
where, e is a constant or Euler's number is:
e ≈ 2.71828183
On comparing (1) and (2) we get
Therefore, the base of the natural logarithm function is e.
Barry found a computer at Staples for $989. A week later, the computer went on sale for $849. The percentage change is 14.156 % decrease
<em><u>Solution:</u></em>
Given that Barry found a computer at Staples for $989
A week later, the computer went on sale for $849
To find: percent of change
Percent change is the extent to which a variable gains or loses value. The figures are arrived at by comparing the initial (or before) and final (or after) quantities according to a specific formula.
<em><u>THE PERCENT CHANGE IS GIVEN AS:</u></em>
If the result is positive, it is percentage increase
If the result is negative, it is percentage decrease
Here initial value = 989 and final value = 849
Substituting the values in above formula,
Here negative sign denotes percentage decrease
Thus percentage change is 14.156 % decrease
