So remember that the area of a trapezoid is 
, with b = bases and h = height. Before we can do the equation, however, we have to find the height. Using the right triangle, we can use the pythagorean theorem, which is 
.
Since we know that the hypotenuse is 13 and one of the legs is 12, we can solve for the other leg. Our equation will look like this: 
Firstly, solve the exponents: 
Next, subtract 144 on both sides: 
Next, square root both sides, and your height will be: x = 5
Now that we know both the height, 5, and the bases, 30 and 40, we can solve for the area of the trapezoid. Our equation will look like this: 
Firstly, combine everything on the numerator: 
Next, divide the fraction: 
Next, multiply, and your answer will be A = 175 un^2.
Answer:
17 days
Step-by-step explanation:
Number of days in which 3 men can finish a house repair job = 10 days
Number of days in which 1 man can finish a house repair job = 
days
Therefore,
Number of days in which 5 men can finish a house repair job = Number of days in which 1 man can finish a house repair job × 5
≈ 17 days
Answer:
3.07
Step-by-step explanation:
Since you can only obtain exactly $10 if you have an even amount of quarters you will need to plot 2x + y. With 'x' being the quarters and 'y' being the dimes.
