Answer:

6 + 7 = 13

Step-by-step explanation:

We are given the following information in the question:

We know that

6 + 6 = 12

We need this information to evaluate

6+7

The evaluation can be done with the help of using associative property and distributive property.

Associative property: (a + b) + c = a + (b + c)

The evaluation can be shown as:

6 + 7\\= 6 + 6 + 1\\=(6 + 6) + 1\\= 12 + 1\\=13

Answer:

d

Step-by-step explanation:

base² + Altitude² = Hypotenuse²

 x² + 9² = 13²

x² + 81 = 169

       x² = 169 - 81

      x² = 88

      x = \sqrt{88}

     x = \sqrt{2*2*2*11}=2\sqrt{2*11}\\\\x=2\sqrt{22}

Please help me I need this question done by tonight. The amount that a consultant charges for her work can be modeled using a li
nataly862011 [7]

Answer: The consultant earn $50 each hour.

Explanation:

It is given that for 4 hours of work, the consultant charges $400. For 5 hours of work, she charges $450. The amount that a consultant charges for her work can be modeled using a linear function.

If the linear function represents the amount earn by consultant in hours the the coordinates can be written as (4, 400) and (5, 450).

If we want to find how much money does the consultant earn each hour, so first we have to find the slope of linear function which passing through two points (4, 400) and (5, 450).

\text{Slope}=\frac{y_2-y_1}{x_2-x_1}

\text{Slope}=\frac{450-400}{5-4}

\text{Slope}=\frac{50}{1}

\text{Slope}=50

In the linear function the slope show the earning of consultant per hour, therefore consultant earn $50 each hour.
