Answer:
7 fossils
Step-by-step explanation:
Find the cost for transportation by multiplying 20 by 5, since it is $5 per student and there are 20 students
20(5)
= 100
Subtract this from 128, since they raised $128
128 - 100
= 28
This means they have $28 to spend on fossils.
To find how many they can buy, divide 28 by 4, since they are $4 each
28/4
= 7
So, they can buy 7 fossils with the money they have left

Step-by-step explanation:
The formula for the area of a circle is π*r^2, r being the radius or the half line in the circle, and the formula for the circumference is π*r*2, or π*d, or the diameter which is the line that goes all the way through like number 5. The radius is half the diameter.
Answer:
<u>Given:</u>
- 2x + 9 < 0 ⇒ 2x < - 9 ⇒ x < - 4.5
- x > -12
<u>Combined we have:</u>
<u>The integers in the same interval are:</u>
- x ∈ {-11, -10, -9, -8, -7, -6, -5}
