I’m assuming the question is to find the number of calls made? If so here’s how to solve it.
18 + 0.5x = 50.50
.05x = 32.50
x = 650
650 calls made.
It's 0.375 because I converted it to a decimal and anything divided by 1 is itself
Katie has enough bricks because it only takes 12,948 bricks to build the wall. To get 12,948, you will multiply 332 by 39. So basically you are multiplying the width by how tall it is.
The common difference is (1,0.38).
An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same. In this type of progression, there is a possibility to derive a formula for the nth term of the AP. For example, the sequence 2, 6, 10, 14, … is an arithmetic progression (AP) because it follows a pattern where each number is obtained by adding 4 to the previous term.
x1 = 1 , y1 = 24
x2 = 2, y2 = 24.38
x3 = 3 , y3 = 24.76
x4 = 4 , y4 = 25.14
Thus the common difference equals :-
x2 - x1 = x3 - x2 = x4 - x3 = 1
y2 - y1 = y3 - y2 = y4 - y3 = 0.38.
Thus the common difference is (1,0.38).
