Exact=56.5 rounded would be 57 because you can't make half a birdhouse.
Answer:
The ratio of male nurses to female nurse in lowest terms is: 2:5
Step-by-step explanation:
Given: In a hospital, there are total 250 registered nurses.
Number of nurses are males = 100
Number of nurses are females = 250 - 100 = 150 [ Total nurses - number of male nurses]
To find the ratio of male nurse to female nurses in lowest terms;
A ratio shows that the relative sizes of two or more values.
Then,
= 
or
=
= 2:5
Therefore, the ratio of male nurses to female nurses in lowest terms is; 2 :5
Answer:
Below
Step-by-step explanation:
● x^2 + 11x + 121/4 = 125/4
Substract 125/4 from both sides:
● x^2 + 11x + 121/4-125/4= 125/4 -125/4
● x^2 + 11x - (-4/4) = 0
● x^2 +11x -(-1) = 0
● x^2 + 11 x + 1 = 0
This is a quadratic equation so we will use the determinanant (b^2-4ac)
● a = 1
● b = 11
● c = 1
● b^2-4ac = 11^2-4*1*1 = 117
So this equation has two solutions:
● x = (-b -/+ √(b^2-4ac) ) / 2a
● x = (-11 -/+ √(117) ) / 2
● x = (-11 -/+ 3√(13))/ 2
● x = -0.91 or x = -10.9
Round to the nearest unit
● x = -1 or x = -11
The solutions are { -1,-11}

This question is too difficult
Hey there! I'm happy to help!
We want to see how many times bigger 2/5 is than 9/10. Let's call how much bigger 2/5 is b and solve below.
9/10b=2/5 (2/5 is b times larger than 9/10)
We divide both sides by 9/10, so your division would be 2/5÷9/10.
b=4/9
Therefore, the builder worked 4/9 times as long in the morning as he did in the afternoon.
Have a wonderful day! :D
