Answer:
the value of a would be one, i think
66 2/3
=(66*3+2)/3
=200/3
((200/3)*39)/100
=(7800/117)/100
=78/1.17
=66.7%
not so sure it is right though, but that's what I came up with. hope it helps
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:
9
Step-by-step explanation:
They both have -10 so just compare 3 and 12. Thats a difference of 9.
Answer:
1 cm
Step-by-step explanation:
To solve this problem we can use the Pythagorean theorem. In fact the diagonal of a rectangle is an hypotenuse of a right triangle, while the length is a leg. The width is the other leg
width = √2^2 - (√3)^2 = √4 - 3 = √1 = 1 cm
