Find the values of the ratios (red to blue) of the perimeters and areas of the similar figures. Write the ratios as fractions in simplest form.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
BLUE PENTAGON
The blue shape represents the Pentagon
The length of the side a = 7
As there are 5 sides.
Thus,
The Perimeter of the Blue Pentagon = P = 5a = 5(7) = 35
Using the formula to determine the area of the Pentagon
[tex]A=\frac{1}{4}\sqrt{5\left(5+2\sqrt{5}\right)}a^2\:\:\:\:\:\:\:\:\:\:\:\:\:[/tex]
[tex]A=\frac{1}{4}\sqrt{5\left(5+2\sqrt{5}\right)}\left(7\right)^2\:\:\:\:\:\:[/tex]
[tex]A\approx 84.3\:\:\:[/tex]
Thus,
The Area of the Blue Pentagon = [tex]A\approx 84.3\:\:\:[/tex]
RED PENTAGON
The red shape represents the Pentagon
The length of the side a = 4
As there are 5 sides.
Thus,
The Perimeter of the Red Pentagon = P = 5a = 5(4) = 20
Using the formula to determine the area of the Pentagon
[tex]A=\frac{1}{4}\sqrt{5\left(5+2\sqrt{5}\right)}a^2\:\:\:\:\:\:\:\:\:\:\:\:\:[/tex]
[tex]A=\frac{1}{4}\sqrt{5\left(5+2\sqrt{5}\right)}\left(4\right)^2\:\:\:\:\:\:[/tex]
[tex]\:A\approx 27.5[/tex]
The Area of the Red Pentagon = [tex]\:A\approx 27.5[/tex]
Conclusion:
The Perimeter of the Blue Pentagon = 35
The Perimeter of the Red Pentagon = 20
Thus, the ratio of the perimeter is: 35/20 = 7/4
The Area of the Blue Pentagon = 84.3 = 843/10
The Area of the Red Pentagon = 27.5 = 275/10
Thus, the ratio of the Area is:
[tex]\frac{\frac{843}{10}}{\frac{275}{10}}=\frac{843}{275}[/tex]

I have a very relaxing break playing Solitaire as often as I could. After playing 500 games, my success rate is 49%. How many games do I need to win to increase my success rate to 50%?
Answers
Answer:
5 more games to be won for the 50% success rate.
Step-by-step explanation:
Total number games played = 500
Number of successful games = 49% of 500
= 500 × [tex]\frac{49}{100}[/tex]
= 245
Number of successful games for the success of 50% = 500 × [tex]\frac{50}{100}[/tex]
= 250
Therefore, number of game you have to win more = 250 - 245
= 5 games

A number cube is rolled 360 times and the results are recorded as follows: 52 ones, 59 twos, 67 threes, 73 fours, 42 fives, and 67 sixes. What is the experimental probability of rolling a two or a three?
Answers
Answer:
0.35
Step-by-step explanation:
Total rolled = 360 times
Two rolled = 59
Three rolled = 67
Two rolled probability = 59/360 = 0.164
Three rolled probability = 67/360 = 0.186
The experimental probability of rolling a two or a three
==> Two rolled probability + Three rolled probability
==> 0.164 + 0.186
==> 0.35

Answers
Answer: 2 1/4
Step-by-step explanation:
From the question, we are informed that a baker made 9 cupcakes which are to be shared equally by four people.
To get the number of cupcakes that each person gets, we divide the total number of cupcakes by the total number of people. This would be:
= 9 ÷ 4
= 2 1/4 cupcakes
Therefore, each person gets 2 1/4 cupcakes.

M<2=x+88 can you please tell me the answer for this
Answers
Answer:
Answer: A) -8
Step-by-step explanation:
The image shows the triangle where it can be noted that two of its sides are congruent (according to the tick marks). This forms an isosceles triangle that also has two congruent angles as shown in the image below.
The other angle (2) has a measure of x+88.
The sum of the internal angles of the triangle must be 180°, thus:
x + 88 + 50 + 50 = 180
Simplifying:
x + 188 = 180
x = 180 - 188 = -8
x = -8
Answer: A) -8

The library has 65400 art books and 9600 science books. What part of all the books are science books
Answers
Answer:
9,600/75,000, 16/125
Step-by-step explanation:
art+science=75000
9600
75000 =16/125
The part of all the books that are science books is 0.128 or 16/125.
Using this formula
Science books=Science books(Art books+Science books)
Where:
Science books=9600
Art books=65400
Let plug in the formula
Science books=9600/(65400+9600)
Science books=9600/75000
Science books=0.128 or 16/125
Inconclusion the part of all the books that are science books is 0.128 or 16/125.
