Answer:
2 students in each group
Step-by-step explanation:
If there were 5 groups and after a while 7 students leave early and 3 students remain to do the activity, if you add 7 + 3 = 10 divide it by 5, the number of groups in the activity, you would get 2 students in each group.
151 * 5 = 755
23,000 - 755 = 22,245
It'll be worth $22,245 in 5 years.
Answer:
diameter of a circle = 12cm
Step-by-step explanation:
Area of a circle = πr²
113.04 cm² = πr²
First, search for radius (r) :-
r = √(113.04/π)
r = 6 cm
As diameter is equals to 2×radius
The diameter of a circle = 2 × 6cm
Final answer = 12 cm
Answer:
a) $86.11
b) $467.33
Step-by-step explanation:
no. of gallons saved 'n' per year
n = (10000/33) - (10000/36)
n = 2500/99
Amount saved = 3.41×n = 3.41×2500/99
= $86.11
b) over 5 years:
86.11( 1 + (1.041) + (1.041)² + (1.041)³ + (1.041)⁴ )
= 86.11(5.427157431)
= $467.33
