we know that
If two lines are perpendicular, then the product o their slopes is equal to minus one
so
Step 1
<u>Find the slope of the given line</u>
we have
-------> 
This line is parallel to the y-axis
so
the perpendicular will be parallel to the x-axis
Step 2
The equation of the line perpendicular to the given line is the y-coordinate of the given point
Point 
the equation is
therefore
<u>the answer is</u>
see the attached figure to better understand the problem
The first thing we will do for this case is define variables.
We have then:
x = amount of water to evaporate.
90-x = amount of water after being evaporated.
The amount of salt is:
S = 90 * 0.15 = 13.5
The percentage of salt will be:
% S = 13.5 / (90 - x) = 25/100
Answer:
An equation can be used to find x, the number of gallons that should be evaporated is:
13.5 / (90 - x) = 25/100
Answer:
obtuse
Step-by-step explanation:
45^2 = 2025
42^2 = 1764
13^2 = 169
169+1764=1933
2025 > 1933
therefore it is an obtuse triangle
Answer:
Yes and the total will be $172
Step-by-step explanation:
- 9 x 4 = 36
- Video game store A = $36
- Video game store B = $136
- add $136 to $36 to get $172
It can be deduced that the population proportion formulated shows that the proportion is 3/5.
<h3>How to calculate the population proportion</h3>
Your information is incomplete as the table isn't given. Therefore, an overview will be given. It should be noted that a population proportion simply means a fraction of the population that has a particular characteristic.
In this case, let's assume that the population is 2000 and the most preferred menu item is chosen by 1200 people. Therefore, the <em>population</em> proportion of the most preferred menu item will be:
= 1200/2000
= 3/5.
