C. 4.45 cm. you take the circumference and divide it by pi to find the diameter
Answer:
Blue
Step-by-step explanation:
First, we need to find the LCD (Least common denominator)
Rewriting input as fractions if necessary:
1/10, 1/4, 1/5
For the denominators (10, 4, 5) the least common multiple (LCM) is 20.
Therefore, the least common denominator (LCD) is 20.
Now, we convert:
Red Marbles: 1/10 = 2/20
Blue Marbles: 1/4 = 5/20
Yellow Marbles: 1/5 = 4/20
As we can see, blue has the most. Now we have our answer! Good luck!
Answer:
x = 16
y = 131
Step-by-step explanation:
4x + 2x - 6 = 90
6x = 96
x = 16
16 + 33 + y = 180
49 + y = 180
y = 131
Answer: 35 additional teachers are needed
-------------------------------------------------
-------------------------------------------------
Explanation:
We have 2470 students and the ratio of students to teachers is 26:1. This means that for every teacher, there are 26 students. Put another way, we can set up this ratio
2470/x = 26/1
where x is the number of teachers. Cross multiply and solve for x
2470/x = 26/1
2470*1 = 26*x
2470 = 26x
26x = 2470
26x/26 = 2470/26
x = 95
So we have 95 teachers currently
-------------
Let y be the new number of teachers needed to bring the ratio down to 19:1
Using a similar idea as done above, we would have this ratio
2470/y = 19/1
Let's solve for y
2470/y = 19/1
2470*1 = 19*y
2470 = 19y
19y = 2470
19y/19 = 2470/19
y = 130
So we'll need 130 teachers to have the ratio be 19:1
The difference of the values is y - x = 130 - 95 = 35, which is the final answer. This is the additional amount of teachers needed.
