Answer:
x>0
Step-by-step explanation:
- subtract 1 from both sides
- subtract x from both sides
- x>0
The ideal mechanical advantage of a slope is given by the ratio between the output load, which is simply the weight of the object (), and the input force applied to move the object along the slope:
The energy conservation law states that the potential energy of the object when it reaches the final height h is equal to the work done to move the object along the distance of the slope , i.e.
From this we find
Therefore, we can substitute this into the formula of the ideal mechanical advantage and calculate its value:

Leila will run <u>less than</u> 25 miles this week. This means the inequality symbol will be this: "<". Since she has already ran 13 miles, we need to plug-in a variable for the additional miles she must run. The inequality should be like this when plugged-in: 25 < 13 + t.
The final answer to your question is 25 < 13 + t.
Exponential equation are functions defined by 
The equation that could represent Rainey graph must take the form 
<h3>How to determine the equation</h3>
An exponential equation is represented as:

Where:
- a represents the initial value
- b represents the rate
The initial value (a) is 15.
So, the equation becomes

The graph is not given;
So, the equation cannot be determined.
Assume that the rate is 2.
Then the function would be:

Answer:
The equivalent percentage point drop = 10%
Step-by-step explanation:
The percentage point change is the difference between the final and initial values.
The percentage change is the difference between the final and initial values
divided by the initial value
It is required to decrease the dropout rate from 30% to 20%
The point change = 20 - 30 = -10 (-ve change ⇒ decrease)
The percentage change =
%
So, the equivalent percentage point drop = <u>10%</u>
And the percentage change = <u>33.33%</u>
