The amount earned by Tom is the product of the <em>rate per</em> <em>hour and the number of hours</em> worked which is $90.
- The amount earned per hour = $15
- The number of hours worked = 6 hours
<u>The amount earned at the normal earning rate can be calculated thus</u> :
- <em>Normal rate per hour × number of hours</em>
Amount earned = $15 × 6 = $90
Therefore, the amount earned by Tom after working for 6 hours at the normal rate is $90.

Answer:
5.4
Step-by-step explanation:
3/5 x 9 is 5.4. To find the area of a rectangle you need to multiply the length times the width.
87/1000 into a decimal is 0.087,
You can divide with your calculator, or you can use place value.
0.8 = 8/10
0.87 = 87/100
0.087 = 87/1000
And so on and so forth...
The sum of the 5 terms in the arithmetic series is 40.
Step-by-step explanation:
Step 1; First we need to determine the three values between a1= -14 and a5=30. The difference between the first and fifth value = 30 - (-14) = 30 + 14 = 44.
Since there are 4 values after a1 we divide the difference by the number of terms, the difference between each term = 44 / 4 = 11. So the difference between each term is 11.
Step 2; To find out the terms we just add the difference to the previous number.
a1 = -14.
a2 = -14 + 11 = -3.
a3 = -3 + 11 = 8.
a4 = 8 + 11 = 19.
a5 = 19 + 11 = 30.
So a1 + a2 + a3 + a4 + a5 = -14 -3 + 8 + 19 + 30 = 40.
