Step-by-step explanation:
∑k=150(3k+2)
First find a1 and a50 :
a1=3(1)+2=5a20=3(50)+2=152
Then find the sum:
Sk=k(a1 + ak)2S50=50(5 + 152)2=3925
If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.
Area is the length times the width.
When you know the area and one of the dimensions, divide the area by the known dimension to find the other one.
133 / 11 = 12.09
The room needs to be at least 12.09 feet wide. ( round answer if needed).
Lol that's so cool just give me the poonts
Answer:
$16
Step-by-step explanation:
Let his weekly allowance = x
Amount spent playing golf = x / 2
Amount earned for cleaning car = $4
Final amount at hand = $12
Mathematically ;
x/2 + 4 = 12
x/2 = 12 - 4
x/2 = 8
x = 2 * 8
x = $16
Weekly allowance = $16
