Answer:
Step-by-step explanation:
Hello, let's say that the price was P, a real number.
After 20% discount it become P - 20% * P = P* (1-20%) = P * (1 - 0.2)
= P * 0.8
And then we take 15% for the VAT, the new price become P * 0.8 * ( 1 + 15%)
= P * 0.8 * 1.15
And this is equal to 22080, so
P * 0.8 * 1.15 = 22080
and the amount of the VAT is P *0.8 * 0.15
Hope this helps.
Thank you.
This can be solved using trigonometric functions. The distance x serves as one leg of a triangle, and makes an angle q with the hypotenuse. The distance from the tip of the rocket to the ground make up the other leg of the triangle. So solving this:
tan q = y / x
Where: y = distance from the tip of the rocket to the ground
Therefore, y = x tan q
Among the choices, the correct answer is C.
Answer:
$2.75
Step-by-step explanation:
A quarter's value as placed on it by the U.S. Treasury Department is $0.25, or 1/4 of a dollar.
Henry had 15 quarters, in which he gives his sister 4: 15 - 4 = 11
Henry now has 11 quarters. Multiply 11 with 0.25: 11 x 0.25 = 2.75
Henry has $2.75

Answer:
264.
Step-by-step explanation:
Let x represent the number of trout in the lake.
We have been given that a group of naturalists catch, tag and release 121 trout into a lake. The next day they catch and release 48 trout, of which 22 had been tagged.
Using proportions, we will get:
Therefore, there would be approximately 264 trout in the lake.
