Answer:
189 Gallons
Step-by-step explanation:
7 gallons for 3 classrooms, so 7/3 for 1 classroom
multiply 7/3 * 129 to get 301 gallons at North High School
multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary
301 - 112 = 189 gallons more at North High School than at Edgewater Elementary
(1/A) dA/dt= C where A is the population of ants and C is a constant
ln(A) = C*t + C1 where C1 is another constant that comes out of integration and t is time in days.
Plugging in: at t=0, A= 100 so C1 = ln(100) = 4.605
at t=3, A=230 so ln(230) = 3*C +4.605 so C = 0.278
Final equation:
ln(A) = 0.278t + 4.605
or:
A = exp(0.278t + 4.605)
After 14 days, A = exp(0.278*14 + 4.605) = 4875.2
Answer:
8-27=
Step-by-step explanation:
Answer:
Step-by-step explanation:
4x-5+3x+5+40=180 degree(sum of interior angles of a triangle)
7x+40=180
7x=180-40
x=140/7
x=20
Answer:
The answer is 3.
Step-by-step explanation:
1. You need to substitute the values into the equation
2. You would then have 1/2(4-3(-2))-2
3. Now you have to multiply 3×-2 and you will now have 1/2(4+6)-2
4. Then you have to add what's in the parenthesis and you will have 1/2(10)-2
5. Now multiply 1/2(10) and uou will have 5-2
6. Now subtract 5-2 and that will = 3
