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
The formula used to find the length of a line segment is the same formula as the Pythagoras theorem.
We take CD as the hypotenuse of the right-angled triangle and the distance between the x-coordinates and y-coordinates as the length of two short sides.
We can write the formula as
CD =
CD =
Answer:
<h2>D= 3.9 miles</h2>
Step-by-step explanation:
Given data
speed v= 13 miles per hour
time taken t= 20min to hour 0.3 hours
the distance D
We know that the relationship between speed, time, and distance
speed=distance/time
13=D/0.3
(the expression above describes the relationship between distance, speed, and time)
making D subject of formula we have
D= 0.3*13
D= 3.9 miles
hence the distance is 3.9miles
Answer:
2,500 German chocolate cake boxes.
1,500 Swiss chocolate cake boxes.
Step-by-step explanation:
Let 'S' be the number of Swiss chocolate cakes boxed and 'G' the number of German cholocate cakes boxed. If all of the available ingredients are used:
Solving the linear system above:
2,500 German chocolate cake boxes and 1,500 Swiss chocolate cake boxes can be made each day.
Cows : sheep = 5 : 4
5x + 4x = 648
9x = 648
x = 72
5x = 5 * 72 = 360
4x = 4 * 72 = 288
There are originally 360 cows and 288 sheep.
2/3 of the sheep are sold. That means that 1/3 of the sheep are left.
1/3 * 288 = 96
96 sheep are left.
x cows were sold.
(360 - x)/96 = 3/1
360 - x = 288
-x = -72
x = 72
72 cows were sold
