The measurements are:<span>
b</span>₁ = 8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂ = 2.8 inches<span>
Let x = length of base and leg
The formula for perimeter of isosceles trapezoid is P = b₁ + b₂ + 2(leg)</span><span>
Where: b = base
<span> P = b</span>₁ +
b₂ + 2(leg)</span><span>
<span> 28 = 3x + 5x + 2(x)</span>
<span> 28 = 8x + 2x</span>
28/10 = 10x/10
<span> 2.8 = x</span>
Now, substitute the values:
<span> P = b</span>₁ +
b₂ + 2(leg)</span><span>
<span> 28 = 3(2.8) + 5(2.8) + 2(2.8)</span>
28 = 8.4 + 14 + 5.6
28 = 28
Hence the measurements are:
b₁ =
8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂<span> =
2.8 inches</span></span>
Rounded to the nearest cent which I would assume is the nearest hundredth, the answer is 1.12
Answer:
The three numbers are : 9, 9 and 18
Step-by-step explanation:
Since the mean is 12 the sum of the three numbers must be 36. This is because:
(let the three numbers be x y and z)
(x+y+z)/3=12
(x+y+z)=12*3
(x+y+z)=36
And since the mode is 9 two of the numbers must be 9.
So to find the third number;
9+9+z=36
z=36-18
z=18
The <em><u>correct answers</u></em> are:
C) Wages would decline as the competition for jobs increases; and C) a monopoly in the production of that medication.
Explanation:
If we have a surplus of employees for a decrease in the amount of jobs, it is likely that employers will lower wages, since there is no difficulty in finding employees.
If one company produces a new drug, and no other companies are producing it, there could potentially be a monopoly for that drug.
Answer:
The phrase “ y varies directly as x” or “ y is directly proportional to x” means that as x gets bigger, so does y, and as x gets smaller, so does y. That concept can be translated in two ways. for some constant k. The k is called the constant of proportionality. Therefore a chance of probability is a binary table.
