Answer:
<h2>
width = 3 feet</h2>
Step-by-step explanation:
Let h be the height of the door
and w be its width
The statement “The height of the door is I foot more than twice its width”
can be translated mathematically like this : h = 2w + 1
Let’s solve the equation for w:
h = 2w + 1
⇔ 2w = h - 1
now , if the door is 7 feet high then it’s width is equal to :

Answer:
1. 90-68= 22
2. 90-80= 10
3. 90-3= 87
Step-by-step explanation:
A complement angle is found by their sum being 90 degrees. So, you are looking for the angle that would add to the given angle to = 90.
Answer:
The simplified form of the expression is 
.
Step-by-step explanation:
The expression is:
The division rule of exponents is:
The negative exponent rule is:
Simplify the expression as follows:
![\frac{x^{-3}\cdot y^{2}}{x^{4}\cdot y^{6}}=[x^{-3-4}]\times [y^{2-6}]](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-3%7D%5Ccdot%20y%5E%7B2%7D%7D%7Bx%5E%7B4%7D%5Ccdot%20y%5E%7B6%7D%7D%3D%5Bx%5E%7B-3-4%7D%5D%5Ctimes%20%5By%5E%7B2-6%7D%5D)
Thus, the simplified form of the expression is .
Ok so this is a simple question and this is the step by step on how to solve it.
1. take 65 · 15 to get 975 meters in 15 seconds
2. take 975 · 3.3 to get 3217.5 feet pet 15 seconds.
thus making the answer 3217.5 ft
Hope this helped :)
