1. Let's call 
to the number of equipment operators and 
to the numbers of laborers.
2. Based on the information given in the problem above, you can make a system of equation, as following:
3. By applying the method of substitution, you can solve for from the second equation and substitute it into the first equation to solve for , as following:
4. Now, substitute the value of into the second equation to calculate :
The answer is: 19 equipment operators and 13 laborers.
Answer:
936mm^2
Step-by-step explanation:
Surface area of cuboid 20 mm 8mm 11mm
Surface area of the cuboid=2(20×8+8×11+11×20)
=2(160+88+×220)
=2(468)
=936mm^2
So the answer is936mm^2
Answer:
Scatter plots can be a little confusing, but all you need to do is look for an association (what direction the dots appear to be going in). Positive association resembles this / whereas negative association resembles this / flipped the other way. It could also be a curved line, which would be a nonlinear association. If it appears to have no direction at all it has no association. Other wise, all you have to do is read the data to answer the questions. e.g. for the first question find the highest score in the right side of the table and then the corresponding number in the left side. Hope this helps!
Answer: the equations are
0.02x + 0.07y = 156
y = 300 + x
Step-by-step explanation:
Let x represent the total dollar amount of phone sales that she makes.
Let y represent the the total dollar amount of computer sales that she makes.
Josiah earns a 2% commission on the total dollar amount of all phone sales he makes, and earns a 7% commission on all computer sales. She earned a total of $156 in commission. This means that
0.02x + 0.07y = 156 - - - - - - - - - - -1
Josiah had $300 more in computer sales than in phone sales. This means that
y = 300 + x
