One third of a bird eggs hatched. If 2 eggs hatched , how many eggs did the bird lay
VLD [36.1K]

Answer:

6 eggs

Step-by-step explanation: you need to divide 2 by one-third. So, set it up. 2/1 divided by 1/3. The method I use is keep, change, flip. Keep 2/1, and flip 1/3 to 3/1. Now you have 2/1 multiplied by 3/1 which is 6.

1 Solve for the unknown variable:
Burka [1]

Answer:

Approximately 6.4

Step-by-step explanation:

We can use the pythagorean thereom here, that tells us (a^2)+(b^2)=c^2. C is the hypotenuse, the side opposite from the right angle, while a and b are the other sides. We can insert 5 and 4 as a and b, and solve for c

:(5^2)+(4^2)=c^2

:25+16=c^2

:41=c^2

:sqrt(41)=6.4=c              (We square rooted both sides. 6.4 is only rounded to the nearest hundredths place.) Hope this helps!
