A worker in a factory earns $10 an hour the world the worker works 10 hours a day for 10 days straight before vacation. How many money did the worker earn before going on vacation? $3^10 $10^1 $10^3or $10^2
The worker earns $10 per hour and works 10 hours a day for 10 days.
10 hours/day * $10/hour = $100/day
$100/day * 10 days = $1000
Therefore, the worker earns $1000 before going on vacation. So the correct answer is $10^3.
Three raised to what power is equal to 81
Three raised to the power of 4 is equal to 81.
3^4 = 81
What are the variables in the equation Y equals 3X -4
In the equation Y = 3X - 4, the variables are:
- Y (dependent variable)
- X (independent variable)
A sign is being painted that includes three small squares with a side length of S and two large ones with a side length of S right expression to find the total area of the sign that needs to be painted
Two raised by 2+ 3S raised by two
2S raised by two minus 3S raised by two
3S raised by two minus 2S raised by two
3S raised by 2+ 2S raised by two
The sign includes 3 small squares with a side length of S, and 2 large squares with a side length of S. The total area of the sign that needs to be painted can be calculated by adding the areas of all the squares.
Area of a square = side length * side length
For 3 small squares with a side length of S:
Total area of small squares = 3 * S^2
For 2 large squares with a side length of S:
Total area of large squares = 2 * S^2
Adding both the areas gives:
3S^2 + 2S^2
This simplifies to:
3S^2 + 2S^2 = (3 + 2)S^2 = 5S^2
Therefore, the correct expression is 5S^2.
Evaluate the expression, adds specific values of their variables
Evaluate a raised by five minus BC +4 a divided by C when eight equals 2B equals three and C equals eight
Given the expression: a^5 - BC + 4(a/C)
Given the values:
a = 8
B = 2
C = 3
Substitute the values into the expression:
a^5 - BC + 4(a/C) = 8^5 - (2)(3) + 4(8/3)
This simplifies to:
8^5 - 6 + 32/3
Now, you can calculate the values:
8^5 = 32768
32/3 = 10.67
Now, plug these values back into the expression:
32768 - 6 + 10.67
Therefore, the evaluated expression is 32772.67.
