She hit 35% of the times.
35% of 20
= (35/100) * 20
= 0.35 * 20
= 7
Answer:
The options 2x² + x² + x = 30 and 9x + 3x² = 14 + x + 1, and -x² + 4x + 7 = - x² - 9
Step-by-step explanation:
After being rearranged and simplified, which of the following equations could be solved using the quadratic formula?
The answers are:
2x² + x² + x = 30
9x + 3x² = 14 + x + 1
-x² + 4x + 7 = - x² - 9
Alright! We know that the total number of students is 100%. So, if 65% of the students brought a hot lunch, in order to find how many students brought a packed lunch you subtract it from 100%:
[100 - 65] = 35
So 35% of the students brought a packed lunch. Now, in order to find the fraction of students you simply put 35% of students over the total percent of students (100%)"
[35/100]
Then you simply:
[35/100] ⇒ [7/20]
The answer is 7/20ths of the students brought a packed lunch.

Explanation: I'll skip the lengthy explanations because you said "ASAP."
v=gt,
Initial value when time t=0, v=g*0=0.
t=0 s, v=0 m/s means that object’s initial velocity 0 m/s.
v=gt, and g is a constant g=9.8 m/s². We can write v=9.8*t.
Rate of change 9.8 means the acceleration due to gravity is 9.8 m/s².
Answer: C. The initial value is 0. That means that object’s initial velocity 0 m/s. The rate of change is 9.8. That means the acceleration due to gravity is 9.8 m/s2.
