Answer:
Step-by-step explanation:
x= 180-110(angles on a straight line)
x= 70
y=x=70 (alternate angles)
z= 110(alternate angles)
Answer:
17) 750/9 and 18) 364
Step-by-step explanation:
17. Summation of 75*(0.1)^i from i=0 to infinity, that is equal to 75*(Summation of (0.1)^i). Summation of (0.1)^I is a geometric series with a sum of 1/(0.9)=10/9. Hence the series have a sum equal to 75*(10/9)=750/9
18) It's a series with sum=1+3+9+27+81+243=364
Answer:
3.8 inches
Step-by-step explanation:
Divide 24 by 3.14 (Pi) then divide that number by 2
So 0.1 really means 1/10 of 1 so 10 times of 1/10 is 10/10 or 1
