To solve this problem you must apply the proccedure shown below:
1. You have that a1=6 and r=1/3, therefore you must apply the following formula:
Sn=a(1-r^n)/1-r
2. When you substitute the values shown above, you obtain:
S5=6(1-(1/3)^5)/(1-(1/3))
S5=242/27
Therefore, the answer is 242/27
Your answer would be A. so you take 8 and divide it by 1 to get 0.125. then you add 852 to it and then you get 852.125 so now you just round it so it's 1 because it's lower than 5. Make since???
Okay. To find the speed in meters, do 75 * 1,000. because 1,000 meters = 1 kilometer. 75 * 1,000 is 75,000. The speed is 75,000 meters an hour. But, it asks for meters per second and there are 3,600 seconds in one hour. To find this, we have to do division. 75,000/3,600 is 20.8 when rounded to the nearest tenth. The car goes about 20.8 meters per second.
Use distributive property for each side of the equation
1.) 10(x+2)>-2(6-9x)
2. 10x + 20> -12+18x
Then whatever you do to one side of the equation, you do to the other. So we’re trying to get x alone on one side.
Subtract 10x from each side
3.)20> -12 + 8x
Add 12 to each side
4.) 32>8x
Divide each side by 8 to get x alone
5.) 4 > x
