Suppose
At the same time, we can write
Note that (just reverse the sum). Let's pair the first terms of and , and the second, and the third, and so on:
Now, each grouped term in the sum on the right side adds to 151. There are 52 grouped terms on that same side (because there are 50 numbers in the range of integers 51-100, plus 50 and 101), which menas
But , as we pointed out, so
Amount of money saved by Jordon for the video game = (4/5) * 80
= 4 * 16 dollars
= 64 dollars
So
The amount of money that
Jordan needs to earn more for buying the video game = (80 - 64) dollars
= 16 dollars
Amount earned by Jordan per hour working at a pizza shop = $7.75
Let us assume the number of hours Jordan needs to work to save the rest of the money for the video game = x
Then
7.75x = 16
x = 16/7.75
= 2.06 hours
So it can be said that Jordan has to work 3 hours to save the rest of the money for the video game. If Jordan works 2 hours then he will be short of the required amount. If Jordan works for 3 hours he will have some excess amount in his hand after saving for the video game.
Answer:
$1995.97.
Step-by-step explanation:
Amount in bank after 20 days =
18000(1 + 0.05/365)^20
= $18049.38
So H = 18049.38 - 16093.41
= $1995.97.
Answer: 131.1287 square mm (approx)
Step-by-step explanation:
The area of a triangle,
Where and are adjacent sides and is the include angle of these sides,
Here PR and QR are adjacent sides and ∠R is the included angle of these sides,
Thus, we can write,
, and ,
Thus, the area of the triangle PQR,
