Answer:
19.8 minutes
Step-by-step explanation:
Total time the 4 laps was completed = 4 x 2.5 = 10 minutes
Total time the 2 laps was completed = 2 x 4.9 = 9.8 minutes
total time = 10 minutes + 9.8 minutes = 19.8 minutes
Vertical angles congruence theorem, then SAS
A(n) = a₁.(r)ⁿ⁻¹, where a₁ = 1st term, r= common ratio and n, the rank
In the formula given a₁ = 5, r = 3/2 and n = 6 (we have to find the 6th term value).
a₆ = 5.(3/2)⁶⁻¹ = 5.(3/2)⁵ = 1215/32 (answer C)
Answer:
a.) =30.72*50
b.)13.02*50
Step-by-step explanation:
you got to calculate the area of the two rooms by multipling the sides.
as we know that the scale is 1:50, this means for every 1meter it is 50 meters.
once we have calculated the area of the space used multply it by 50 to get the area dimensions occupied
