Answer:
Step-by-step explanation:
The equation of a line passing through two given points (x1,y1) and (x2,y2) is given by:
In this case, x1=-8,y1=8,x2=1,y2=-10
Substituting these values in the equation:
Simplifying,
=>
=>
=>
=>
f(6) = 1+2+4+8+16+32 = 63
f(7) = 63 + 64 = 127
This is a geometric sequence where r the common ratio = 2.
f(n) = a1 * (r^n - 1) / (r - 1)
here a1 = 1 and r = 2 so
f(n) = (2^n - 1) / (2 -1)
= 2^n - 1.
When n = 64 ( the last square on the chess board)
f(n) = 2^64 - 1 = 2^64 ( I think we can neglect the 1!!)
That is the total number of grains of rice.
In tons of rice this is 2^64 / (25,000 * 2000)
= 3.689349 * 10^11 tons approximately.
So for each person the amount of rice would be 3.689349 * 10^11 / 6 * 10^9
= 61.5 tons approx. (Answer).
Answer:
120°
Step-by-step explanation:
We can see that b=a by opposite exteriors.
So a+1/2a=180
1.5a=180
a=180/1.5=120
And since b and a are equal, b also equals 120°
Your answer to 2/3x-4= -2 would be
x=3, or letter D
Answer:
- City A was the warmest
- City B was the coolest
Step-by-step explanation:
If we list the temperatures from lowest to highest, they are 58, 60, 64, 68. The highest temperature was the warmest. It was recorded in City A.
The lowest temperature was the coolest. It was recorded in city B.
City A was the warmest; city B was the coolest.
