Given:
In the given triangle,
With respect to 30°, the perpendicular = 9, the base = x and the hypotenuse = y
To find the value of x and y.
Formula
By Trigonometric ratio we get,
and
Now,
Putting, perpendicular = 9 and we get,
or,
or, [ by cross multiplication]
Again,
or,
or, [ by cross multiplication]
Hence,
The value of x and y is 9√3 unit and 18 unit respectively.
Answer: The total number of ways are 792 ways.
Explanation:
The total number of spots available is 7.
The total number of eligible candidate is 12.
To find the number of combinations we have a combination formula.
Where n is total number of of objects and r is the number of selected objects.
Since we have to select 7 spots from 12 candidates, therefore the total number of ways is calculated as shown below,
Therefore, the total number of ways are 792 ways.
Answer:
Alex had $196.54 in her account before the purchase.
Step-by-step explanation:
Given:
Amount spend on medicines = $35.31
Balance Amount Remaining = $161.23
We need to find the amount in her account before purchase.
Solution:
Let the amount in her account before purchase be 'x'.
Now we can say that;
Amount in her account before purchase minus Amount spend on medicines is equal to Balance amount remaining.
framing in equation form we get;
Now by Using Addition property of equality we will add both side by 35.31 we get;
Hence Alex had $196.54 in her account before the purchase.
