The inequality would be
0.75q ≥ 0.70(q+1)
q is defined as the number of questions he answers after the first one. We are told he gets 75% of those correct; 75%=75/100=0.75. This gives us 0.75q.
Since he gains proficiency on the exercises, the total number he gets correct has to be at least 70%. This means the inequality would have the symbol greater than or equal to, as it cannot be less and have him gain proficiency.
He has already answered 1 question and answers q more; this gives us a total of q+1. Since he gains proficiency, the cutoff was 70%; 70%=70/100=0.70. This gives us the expression 0.70(q+1).
Our total inequality would then be 0.75q ≥ 0.70(q+1)
You literally need to apply the formula

where
is the mass and
is the speed
Answer:
<h3> 78%</h3>
Step-by-step explanation:
Given
Number of scientist that line in Antarctica during the winter = 1,100
Amount of scientist in the summer = 5,000
Increment = 5000 - 1100
Increment = 3900
percentage change = Increment/Original amount * 100
Percentage change = 3900/5000 * 100
Percentage change = 3900/50
Percentage change = 78%
<em>Hence the percent change in the number of scientists living in Antarctica is 78%</em>
Answer:
11/4 or 2 3/4
Step-by-step explanation:
3/2+5/4
(3x4) + (5x2)=2x4
=22/8
=22÷2
=8÷2
=11/4 or 2 3/4
Slope = 6/-2 = -3
b = 6
equation
y = -3x + 6
