For this case we expand the series for each value of "n":

125 (\frac {1} {5}) ^ {1-1} +125 (\frac {1} {5}) ^ {2-1} +125 (\frac {1} {5}) ^ {3 -1} +125 (\frac {1} {5}) ^ {4-1} =

125+ \frac {125} {5 ^ 1} + \frac {125} {5 ^ 2} + \frac {125} {5 ^ 3} =\\125+ \frac {125} {5} + \frac {125} {25} + \frac {125} {125} =\\125 + 25 + 5 + 1

So, the correct option is: A

Last winter, Tom earned $47.50 shoveling snow and $122 giving ice-skating lessons. During the summer, he earned twice as much by

You would have to add 47.50 + 122 to get 169.5 dollars. to get the amount of money he made in the summer, you would have to multiply 169.5 by 2 which would equal 339 dollars. so he made 339 dollars over the summer :)

What is the gradient of the blue line
alexandr402 [8]

The gradient is also known as the slope and we can find it using the slope/gradient formula: (y2 - y1) / (x2 - x1)

To find the gradient/slope, we need to first choose two points on the line. You can choose any two points you like, as long as they are on the line you are trying to find the slope of.

Point 1 = (2,2)

Point 2 = (5,8)

Now, we can plug in these points to the formula and solve.

(8 - 2) / (5 - 2)

6 / 3

2

The gradient of the blue line is 2.

Hope this helps!! :)

40÷1+3‐(3×7)+7-5 use pedams to answer the following question
Masja [62]

Hey there!

40 / 1 + 3 ‐ (3 * 7) + 7 - 5

= 40 + 3 - (3 * 7) + 7 - 5

= 43 + 7 - 5 - 3 * 7

= 50 - 5 - 3 * 7

= 45 - 3 * 7

= 45 - 21

= 24

Answer: 24

Good luck on your assignment and enjoy your day!
