This is like a 30-60-90 triangle with a hypotenuse of 7. Since the relationship of the base to the hypotenuse in a 30-60-90 triangle is 1:2, the answer is 7/2=3.5 ft. Hope this helps!

how do you write the quotient (9+i) over (9-i) in standard form? I need the answer but more importantly, I need to learn how to
Scorpion4ik [409]
Since they are the conjugates of each (9-a and 9+a are conjugates, or with any number replacing 9) , we multiply it by (9+i)/(9+i) to get (9+i)^2/(9-i^2)=(81+2i+i^2)/(9-(-1))=(81-1+2i)/(10)=80/10+2i/10=8+i/5. Conjugates work because they make i into i^2 (-1) without any of the sneaky i's in the middle!

Lourdes are 5/6 of a brownie. Zachary are 4/5 of a brownie of the same size. Who are more brownies?
OleMash [197]

Answer:

Lourdes has more brownies.

Step-by-step explanation:

First, you have to find a common denominator. Whatever you do to the bottom of the fraction you do to the top. 5/6 and 4/5 has a common denominator of 30. Multiply both digits in 5/6 by 5. Then multiply both digits in 4/5 by 6. Then you can compare the fractions. With the common denominators, Lourdes should have 25/30 brownies and Zachary has 24/30. Compare.

24/30 < 25/30. So Lourdes has the most brownies!
