Do the unit rate and simplify it and. or make an equation
Answer:
8.90 seconds
Step-by-step explanation:
When the rocket hits the ground, its height ( <em>y</em> ) will be zero. This means we can write the equation as:
So we need to <u>solve that equation</u>:
- x =

x₁ = -0.84
x₂ = 8.90
We discard x₁, as it is negative.
So the answer is x₂, 8.90 seconds.
Answer:
D, A,B I think that’s it
Step-by-step explanation:
2/8. Because 5-7= 2. And you always keep the dominator if both dominators are the same number.
First, find what percentage of students had 3 or more by adding up your known percents:
45% + 23 % + 21% + x% = 100%
x = 11%
Since you're given that 96 students had 2 or more, you add up the percentages of 2 and 3 or more:
11 + 21 = 32%
Now set up a proportion that relates it to the whole:

This will allow you to find the total number of students at the school.
Cross multiplying and solving for x results in 300 total students.
Question 1:
45% had one or more absences. 45% of 300 students is
135 students.
Question 2:
As we found before, 11% of students had three or more. 11% of 300 is
33 students.
