Answer:
242/27
Step-by-step explanation:
Using the formula for the sum, you can fill in the given values and do the arithmetic.
Sn = a1·(r^n -1)/(r -1)
S5 = 6·((1/3)^5 -1)/(1/3 -1) = 6(-242/243)/(-2/3) = 6·(121/81)
S5 = 242/27
_____
Or, you can write the terms and add them up. The sum is ...
6 + 2 + 2/3 + 2/9 + 2/27 = (162 +54 +18 +6 +2)/27 = 242/27
Answer:
307 paces
Step-by-step explanation:
First, lets convert Robert's pace to metres. (cm > m)
75cm = (75/100)m
= 0.75m
Number of Full Paces = Length of Bridge / 1 Full Pace
=
See , we must have full paces, and in this case we are finding the minimum number of paces, so we will be looking at the lowest possible whole number, which in this case, is 307 paces.
Answer: 1,300,000
Step by step explanation:
Set up a proportion.
65 • 2,000,000 = 130,000,000
130,000,000 / 100 = 1,300,000
1,300,000 is 65% of 2,000,000
Step-by-step explanation:
We know that we have the formula that F = ma
Given
Force (F) = 7.5 N
Acceleration (a) = 15 m/s²
Mass (m) = ?
Now
F = ma
7.5 = m * 15
m = 7.5/ 15
Mass = 0.5 kg
