What is the sum of the geometric series Σ2
Σ(3)
rounded to the nearest whole number?
Answer: O2
A mixed number can be a sum, but you can change the mixed number into an improper fraction by multiplying the whole by the denominator and adding the numerator
Answer:
Area of original = 169m^2
Area of new = 676m^2
Step-by-step explanation:
Area of a square = (length of side)^2
13^2 = 13 * 13 = 169
If the dimension is doubled:
(2*13)^2 = 26^2 = 676
Answer:
7.5cm
Step-by-step explanation:
3 cm on map = 10 km
x cm on map = 25 km
Cross multiply
10x = 25 x 3
10x = 75
therefore Xcm = 75/10
thus Xcm = 7.5cm
