<u>Geometry</u>

  • Sum of Angles: 180(n - 2)°

Step-by-step explanation:

<u>Step 1: Identify</u>

We have a polygon, so n = 4.

  1. Substitute [SA]:                    180(4 - 2)°
  2. (Parenthesis) Subtract:        180(2)°
  3. Multiply:                                360°

This tells us the sum of all angles in the shape.

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Set up equation:                     90° + 93° + 89° + x° = 360°
  2. Combine like terms:               x° + 272° = 360°
  3. Isolate <em>x</em>:                                  x = 88°

There are 6 flavors of candy in a bag. The probability of randomly selecting strawberry is 1/4, lime is 3/16, cherry is 1/8, and
Iteru [2.4K]
The answer is 3/8. You can find a common denominator of 64 among all of the fractions. From this, you can find how many orange candies there are. There is 64 candies, and 40 of them are other flavors, so there's 24 orange candies. You can create the fraction 24/64 and simplify it down to 3/8.

The line plot shows the weight of the bags of beans.what is the average weight of the bags.
Setler79 [48]

Answer:

1/2

Step-by-step explanation:

So you have 12 bags total.

2 are 1/6 so their total weight is 1/3

2 are 1/3 so their total weight is 2/3

3 are 1/2 so their total weight is 3/2

4 are 2/3 so their total weight is 8/3

1 is 5/6 so their total weight is 5/6

Now add all of these up:

1/3 + 2/3 + 3/2 + 8/3 + 5/6 = 36/6 = 6

Then divide by the number of bags to get the average weight: 6/12 = 1/2

.

Step-by-step explanation:

-\frac{3}{16}  + (-\frac{5}{2} )

= -\frac{3}{16}  - \frac{5}{2}

= \frac{-3 - 5(8)}{16}

= \frac{-3 - 40}{16}

= -\frac{43}{16}
