Find the area of the shaded region to the nearest tenth. See picture for full problem. Please and thank you so very much!
Romashka [77]

Answer:

66.3 sq ft

Step-by-step explanation:

Here's the plan: we'll find the area of the circle then subtract the area of the triangle.

Area of circle:

A = pi•r^2

= pi•6^2

= 3.14•36

~= 113.04

Area of triangle:

A = 1/2bh

= 1/2(10.39)(9)

The height is the 6+3 in the image.

~= 46.755

Subtract to find

Area of Shaded:

113.04 - 46.755

= 66.285

Round to nearest tenth.

~= 66.3 sq ft

Answer:

(x,y,z) = (2,-2,1)

Step-by-step explanation:

Three equations with three variables are given. Take two equations at a time to eliminate one variable.

                      x + y - z = -1                       .....(1)

                   4x -3y + 2z = 16                   .....(2)

                    2x - 2y - 3z = 5                   ......(3)

Solve (1) and (3) to eliminate z.

To do that multiply (1) by 2 and add (1) and (2). We get:

                        4x - 5z = 3                       ......(4)

Now, solve (2) and (3) and subtract them. We get:

                        2x + 13z = 17                    ......(5)

Solve (4) and (5). Multiply (5) by 2 and subtract. We get:

                                        z  = 1

Substituting z = 1, in (4) we get:  x = 2.

Now to find y, substitute values of x and y in (1).

⇒ x + y - z = -1 ⇒ 2 + y - 1 = -1

⇒ y = -2

∴ Values of (x, y, z) = (2, -2, 1).

An exponential function has a growth factor or 3.76. What is the percentage growth rate?
olganol [36]

The exponential function with a growth factor has a rate greater than 1

The percentage growth rate is 276%

<h3>How to determine the percentage growth rate?</h3>

The growth factor (b) is given as:

b = 3.76

The growth factor (b) is greater than 1.

So, the percentage growth rate (r) is calculated as:

r = b - 1

Substitute known values

r = 3.76 - 1

Evaluate the difference

r = 2.76

Express as percentage

r = 276%

Hence, the percentage growth rate is 276%

How to add fractions 1/3+3/4
BARSIC [14]
You change 1/3 and 3/4 so that they have the same denominator.
The GCF is 12 in this case.

1/3 x 4 = 4/12
3/4 x 3 = 9/12

4/12 + 9/12 = 13/12 or 1 1/12 (One and one twelfth)
