The slope of a line that is perpendicular to another line is the negative reciprocal of the other.
In this case, we know that the slope of the given equation is 2.
Since we're solving for a line perpendicular to it, we simply find the reciprocal of the 2 (It turns into 1/2) and make it negative.
y = -1/2x + b
Since the given states that the new y-intercept is 10, input it into 'b'.
y = -1/2x + 10
If you'd like me to explain anything I did here, just ask :)

C because there are 7 days in a week and Monday is one of them
Answer:
(81 pi)/4 or approximately = 63.62 ft^2
Step-by-step explanation:
As it is a circle, the area for a circle is pi*radius^2, where the radius is 4.5 ft, so area = 4.5^2 * pi.
Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
There is a supply of 20% saline solution and a supply of 50% saline solution.
If a teacher wants to mix together to get 60 ml of 28% saline solution for an experiment.
We will use "Mixture Allegation" to find the quantity of each solution:
Ist type of solution II nd type of solution
20% 50%
28%
--------------------------------------------------------------------------------------
50%-28% : 28%-20%
22% : 8%
11 : 4
Since there is total quantity of 60 ml of solution.
So, Quantity of 20% solution in the mixture is given by

Quantity of 50% solution in the mixture is given by

Hence, there is 44 ml of the 20% solution and 16 ml of the 50% solution.
Therefore, Option 'B' is correct.
Answer:
Step-by-step explanation:
Find the rate of those two statements:
28 ÷ 16 = 1.75
1.75 ft per seconds
7 ÷ 4 = 1.75
1.75 ft per seconds
Two statements have the same rate, therefore 28 feet every 16 seconds and 7 feet every 4 seconds are equivalent
