Answer:
Step-by-step explanation:11+12/square root of 16
11+(12/4)
11+3
answer is 14
Answer:
7.5
Step-by-step explanation:
Radius = diameter x 0.5
0.5x0.5 = 0.25meter
0.25 meter x 100 cm (100cm in one meter) = 25cm
also for future reference circumference = pie x r squared.
Answer:30 mi
3s = 2.5(s+2)
3s = 2.5s + 5
3s - 2.5s = 5
.5s = 5
s = 5/.5
s = 10 mph to the beach

Confirm this by finding the actual distance each way, should be the same
3*10 = 30 mi
Step-by-step explanation:
Answer:
39.6 cm
Step-by-step explanation:
Applying
s = 2πrθ/360................ Equation 1
Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes
From the question,
Given: r = 9 cm, θ = 252°
Constant: π = 22/7 = 3.14
Substitute these values into equation 1
s = (2×3.14×9×252)/360
s = 39.564
s = 39.6 cm
