I think it's D. 7 times out of 34 times
Answer:
The rate is 609 kilometers per 7 hours.
The unit rate is 609/7 = 87 kilometers per hour.
Step-by-step explanation:
Should be right
Unit rate because unit is referring to one so for example for every unit, there are 6 apples. The unit in the case would be a box
Answer:
Well, in math..
for example, There is triangle ABC, and ur translating it 3 units to the right on a grid...

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.
