Answer:
1.04 inch
Step-by-step explanation:
Given: Old house has a basement stairways with 7.25 inch vertical riser and 7 inch horizontal treads.
Remember; horizontal treads is known as run in steps.
Now, calculating the slope of the stairways.
Formula: 
Rise= 7.25 inch
Run= 7 inch.
Subtituting the value in the formula
Slope=
(∵ Round to two decimal)
∴ Slope of stairways is 1.04.
To solve this problem you must apply the proccedure shown below:
1. You have the the<span> 13.5-m fire truck ladder is leaning against a wall and the ladder makes an angle of 39 degrees 45 ' with the horizontal.
2. Then you have:
3</span>9 degrees 45'=39.75°
<span>
Sin(39.75°)=d/13.5
d=13.5x</span>Sin(39.75°)
<span> d=8.63
</span>
Answer: 64 years old
Step-by-step explanation:You subtract 2082 by 2018 to get the sum of 64
5 times 10.50 = $52.5
An additional $45
3 times 22 = $66
An other additional $65
The total price her shopping list costs is 229.5
Now, $300 - $229.5 = $70.5
Teri will have $70.50 left after buying these items.
Based on the wording of the question, I believe that the answer allows you to pick more than one. However, there still may only be one answer.
