Answer:
A.
Step-by-step explanation:
We have been given a right triangle. We are asked to find the equation that can be used to solve for x.
We can see that x is opposite side of the 20 degree angle and side length of 10 units is adjacent side.
We know that tangent relates opposite side of right triangle to adjacent side.
Therefore, our required equation is and option A is the correct choice.
In question a. it supply us with the info needed. So if the water troughs capacity
is
Then we will divide 160,000 by 5,000.
That would equal to 32.
Or 32 pigs per trough.
Hope I helped!
Lets name the number of guppies in the tank as x
number of goldfish in the tank is 6 times the amount of guppies.
since the amount of guppies is x, then number of goldfish is 6 * x = 6x
therefore total amount of guppies and goldfish is x + 6x
there are total of 21 fish
therefore x + 6x = 21
7x = 21
x = 21/7
x = 3
therefore number of guppies = 3
number of goldfish -6x and x = 3 therefore 3 x 6 = 18 goldfish
we are asked to find how many more goldfish than guppies
we have to find the difference
18 - 3 = 15
there are 15 more goldfish than guppies
It would be B because 64.35/7.15=9 so e=9
