1) we calculate the total cost of all items:
Total cost=27 * $1.25 + 5 *1.99$ + 1*1.5$=$33.75 + $9.95 + $1.5=$45.2
2)we express the total cost in cents:
$1=100 cents
$45.2=$45.2 * (100 cents /$1)=4520 cents.
3)we divide 4520 cents among the number of pupils
Each student will pay=4520 cents / 26 =173.84... cents≈174 cents.
Answer: Each student will pay 174 cents.

She got 23 questions correct out of 25. That means you divide 23 by 25, which equals .92. Then , to find the percentage, you multiply it by 100, which gives you 92%
Answer:
dV/dt = 13,5 [Km³/h]
Step-by-step explanation:
The volume f the cube is:
V = x³ where x is a side of the cube, then tacking derivatives with respect to time on both sides of the equation
dV/dt = 3*x² dx/dt
dx/dt = 2 km/h
at the time when the side x = 1,5 Km
dV/dt = 3* (1,5)²*2 [km³/h]
dV/dt = 13,5 [Km³/h]
