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

Find the length of diagonal HJ. Round to the nearest hundredth.
Alisiya [41]

Answer:

The length of the diagonal HJ is 10.82 units

Step-by-step explanation:

* Lets revise the rule of the distance between two points

- d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}, where

 (x_{1},y_{1}) and (x_{2},y_{2}) are the two points

* Lets use this rule to find the length of the diagonal HJ

∵ The coordinates of point H are (-4 , 3)

∵ The coordinates of point J are (5 , -3)

∴ x_{1}=-4 and x_{2}=5

∴ y_{1}=3 and y_{2}=-3

- Lets find the length of the diagonal HJ by using the rule above

∴ HJ = \sqrt{(5-(-4))^{2}+(-3-3)^{2}}=\sqrt{(5+4)^{2}+(-6)^{2}}

∴ HJ = \sqrt{(9)^{2}+36}=\sqrt{81+36}=\sqrt{117}=10.81665

∴ HJ = 10.82

* The length of the diagonal HJ is 10.82 units

Pls I need help with his math problem
Leno4ka [110]

Answer:

  a) P = 0.08s +200

  b) $488

  c) $6250

Step-by-step explanation:

<h3>a)</h3>

Your answer is correct. The commission rate is multiplied by the sales amount, and that product is added to the guaranteed pay to get the paycheck amount:

  P = 0.08s +200

__

<h3>b)</h3>

Fill in 3600 for s and do the arithmetic.

  P = 0.08×3600 +200 = 288 +200 = 488

The paycheck amount will be $488.

__

<h3>c)</h3>

Use the equation for part (a) and solve for P = 700.

  700 = 0.08s +200

  500 = 0.08s . . . . . . subtract 200

  500/0.08 = s = 6250 . . . dollars; divide by the coefficient of s to get this

Sales would have to be $6250.
