Answer:

<em>22 person-hours of labor</em>

Step-by-step explanation:

<em>From the example given, we recall the following statement </em>

<em>Let  the number of person-hours of labor to break up a  driveway and clear away the rubble = be 14</em>

<em>Let the  number of  person-hours of labor to pour and smooth concrete for the new driveway be = 8</em>

<em>We can then sum up both of the activities, which is,</em>

<em>14 + 8 = 22, </em>

<em>Therefore,</em>

<em>To break up a driveway, clear away the rubble, pour the concrete, and smooth the concrete, it will take 22 number of  person-hours of labor to achieve that.</em>

For this case what you must do is add the number of hours to perform the different activities.
 We have then:
 14 person-hours of labor to break up to driveway and clear away the rubble.
 8 person-hours of labor to pour and smooth concrete for the new driveway.
 Adding both activities we have
 14 + 8 = 22
 answer
 it takes to break up to driveway, clear away the rubble, pour the concrete, and smooth the concrete about 22 person-hours of labor

What is the error in the equation
dimulka [17.4K]

Answer:

The fifth line contains the error.

Step-by-step explanation:

Line 1 is the equation.

Lines 2, 3, and 4 are correct.

The error is in the 5th line.

The square root of a negative number is not a real number, so if this problem is solved only with real numbers, there is no solution.

If imaginary numbers are allowed, then the last line should read:

x = \pm\dfrac{i\sqrt{11}}{2}

Pls help i need this done as quick as possible
Anvisha [2.4K]

Answer:

Infinite Solutions.

Step-by-step explanation:

m+7=3+m+4

Subtract m from both sides:

m+7-m=3+m+4-m

7=3+4

7=7

Both sides are equal.

This means that the value of m does not affect the end result of 7 = 7, which is true. Thus, there are infinite solutions as any value of m will still make the equation true.

If the circumference is 31.4, what are the radius and the area?
jekas [21]

Answer:

radius = 5 units

area of a circle = 15.7units²

Step-by-step explanation:

given that the circumference of a circle = 31.4

radius = ?

recall that the formulae for finding the circumference of a circle  =  2πr

circumference of a circle  = 2 x 3.14 x r

31. 4 = 6.28r

divide both sides by the coefficient of r which is 6.28

31.4/6.28 = 6.28r/6.28

5 = r

radius = 5 units

therefore the radius of the circle whose circumference is 31.4 units is evaluated to be 5units

to find the area of the circle

recall the formula = πr²

area of a circle = 3.14 x 5²

area of a circle = 3.14 x 25

area of a circle = 15.7units²
