2. The measure of an interior angle of a regular polygon is 160 degrees. Find the number of sides in the
polygon

Answers

Answer:

18 sides

Step-by-step explanation:

(N x 180) - 360 = 160N

180N -360 = 160N

20N = 360

N = 18

Proof:

(18 x 180) -360 = 2880 total degrees

2880/18 sides = 160°

Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?

Answers

Answer:

Cereal A is cheaper by $0.15

Step-by-step explanation:

Cost of a 10-ounce box of Cereal A = $2.70

So,

Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]

Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]

Also,

Cost of a 13-ounce box of Cereal B = $3.64

So,

Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]

Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]

Here,

Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]

Therefore,

Cereal A is cheaper by $0.15

Answers

you would just negate each value, so it would be (-9,-7). you can also double check on a calculator

The image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Rotation of a point A(x, y) 180 counterclockwise about the origin produces an image at A'(-x, -y).

Hence, the image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?

Answers

Answer:

1 hour 42 minutes approx

Step-by-step explanation:

Given data

Mayas work rate= 1/4 room per hour

Reginald work rate= 1/3 room per hour

Let the total time taken for both of them be T

Hence their combined work rate

1/4+1/3= 1/T

3+4/12=1/T

7/12=1/T

T= 12/7

T= 1.7 hours

Hence it will take them 1 hour 42 minutes approx
