We are given that there are 11 animals with a total of 34 legs.
Let G = number of Goats, and D = number of Ducks
then G + D = 11; solving for G, we get G = 11 - D
then, 4G + 2D = 34
substituting the value for G, we get 4(11 - D) + 2D = 34
expanding, we get 44 - 4D + 2D = 34
solving, we get D = 5. Therefore, G = 6
Proof: (5 x 2) + (6 x 4) = 34
Answer:
171.9 degrees.
Step-by-step explanation:
The factor is 180/π.
So 3 radians = (3*180)/π
= 171.9 degrees.
The answer for this problem is 1661
Answer:
Step-by-step explanation:
When two or more quantities have the same exponents, their bases can be multiplied together.
Answer:
x = 80, y = 122
Step-by-step explanation:
I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).
3/4x+2/5x-2=90°,
23/20x - 2=90°,
23/20x = 92°,
92/(23/20)
20/(1/4)
20(4)
= 80.
Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.
180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122
