What is the surface area of this wedge ?
Bess [88]

Answer: 84 ft^2  

Step-by-step explanation:

The whole prism can be divided into  5 surfaces.

Two triangles and 3 rectangles.

 Find the area of each of the 5 shapes and add them together.

The triangle has a  base of 4 and a height of  3.

Area of triangle 1:    A= 4*3 * 1/2  

                               A = 6  

Area of triangle 2:     A = 4*3 * 1/2

                                   A = 6

Area of rectangle 1 :   A= 4*6

                                    A = 24

Area of rectangle 2;   A = 3*6  

                                     A = 18

Area of rectangle 3:    A= 5 *6  

                                      A = 30

Now add the areas together

    6 + 6 + 24 + 18 + 30 + =  84 ft^2

Taylor charges $15 for the first hour of dog walking and $10 for each additional hour or fraction of an hour. The rates that Luc
svetoff [14.1K]

Answer:

Taylor will charge more by $15

Step-by-step explanation:

Given

Taylor

First Hour = $15

Hourly Rate = $10

Lucy:

f(x) = \left \{ {{20x,\ 0 \le \ x \ \le 2} \atop {10x, x>2}} \right.

For a dog walk of 2.5 hours.

Taylor's charges is:

Charges = First\ Hour + Hourly\ Rate * 2.5

Charges = \$15 + \$10 * 2.5

Charges = \$15 + \$25

Charges = \$40

Lucy's charges is:

Here, we consider

f(x) = 10x Because x > 2

i.e 2.5 > 2

So, Lucy's charges is:

Charges = 10 * \$2.5

Charges = \$25

By comparison;

Taylor will charge more by $15

The difference is calculated by:

Difference = \$40 - \$25

Difference = \$15
