<span>Equation:
distance = distance
50x = 55(x-(1/2)
50x = 55x - (55/2)
-5x = -55/2
x = 11/2
x = 5 1/2 hrs (time at which the 2nd train overtakes the 1st train)</span>
Answer:
1094
Step-by-step explanation:
The sum of terms of a geometric series is given by ...
Sn = a1·(r^n -1)/(r -1)
You want the sum for ...
a1 = 2, r = -3, n = 7
Filling in the numbers, we get ...
S7 = 2·((-3)^7 -1)/(-3-1) = 2(-2188)/(-4)
S7 = 1094
Given:
Dimension of box is 7 in, 13 in and 4 in.
To find:
Area of the smallest piece of paper
Solution:
Area of the rectangular box = length × width × height
= 7 × 13 × 4
Area of the rectangular box = 364 in³
Area of the rectangular box = Area of the gift paper to wrap the box
Therefore the area of the smallest piece of paper is 364 in³.
63 5 tens=50
13 ones=10 and 3 leftover 50+13=63
