Answer:
The answer is 
.
Step-by-step explanation:
According to the table, when you insert 6, it should give 1 as the area covered. The equation can be found by the slope formula, the change in y over the change in x. Which is in one increase in y, leads to 6 increase in x.
In that case, the equation holds. The same thing, when you put 12 to x. Gives you 2 as the area covered.
Answer:
The plumber worked 50 hours, and his assistant worked 25 hours.
Step-by-step explanation:
Since a plumber and his assistant work together to replace the pipes in an old house, and the plumber charges $ 30 an hour for his own labor and $ 20 an hour for his assistant's labor, and the plumber works twice as long as his assistant on this job, and the labor charge on the final bill is $ 2000, to determine how long did the plumber and his assistant work on this job the following calculation must be performed:
40 x 30 + 20 x 20 = 1200 + 400 = 1600
50 x 30 + 25 x 20 = 1500 + 500 = 2000
Therefore, the plumber worked 50 hours, and his assistant worked 25 hours.
Answer:
C. 
Step-by-step explanation:
One is asked to find which inequality has (
) in its solution set. Remember that an inequality is another way to represent a set of solutions. In essence, it states that all numbers less than; less than or equal to; greater than; or greater than or equal to, are a part of the solution. One simplifies an inequality in a similar manner to how one simplifies an equation, by using inverse operations and simplification. Just note that when multiplying or dividing the inequality by a negative number, one has to flip the inequality sign to ensure the expression remains true.
Simplify each of the inequalities, then evaluate to see which one has () as a part of its solution set.
A. 
B. 
C.
D. 
As can be seen, option (C ) is the only one that fits this requirement. Since option (C) simplifies down to () or in words, (x) is less than (-2.5). This option is the only one that fits the solution since (-3) is less than (-2.5).
Answer:
Triangle- (height × base)/2
Rhombus-(First diagonal×Second diagonal)/2
Trapezoid- (First base+second base)/2×height
N-gon= (Side-2)*180
