perimeter = length + length + width + width

Answer:

A = 2106 yd^2 P = 210 yd

Step-by-step explanation:

PART A:

A = l x w

A = 78 x 27 = 2106 yd^2

P = l + w + l + w = 78 + 27 + 78 + 27 = 210 yd

3x + 1/3y=12
2y=18x+72

Show all work

A no solution
B one solution
C infinity solutions

Answers

Answer:

B one solution

Step-by-step explanation:

3x + 1/3y=12

2y=18x+72; y = 18x/2 +72/2; y =9x+36

3x + 1/3y=12

multiply all through by 3

9x + y = 36

9x + 9x+36 = 36

18x =36-36= 0

x= 0/18 = 0

y =9x+36

y = 9(0) +36 = 0+36= 36

find the value of the ratio (red to blue) of the areas of the similar figures. Write the ratio as a fraction in simplest form.

Answers

Answer:

16/225

Step-by-step explanation:

Ratio of the area of similar figures = ratio of the square of any of their corresponding side lengths

Thus:

Area of red triangle : area of blue triangle = square of side length of red triangle : square of side length of blue triangle

Area of red : area of blue = 4²/15²

= 16/225

Answer:

(2/5)√5

Step-by-step explanation:

from the sine rule (see attached for reference), we can construct the following relationship

12/sinθ  = (6√5) / sin 90°

recall that sin 90° = 1, hence our equation becomes:

12/sinθ  = (6√5) / 1

12/sinθ  = (6√5)   (rearranging)

12 ÷ (6√5)  = sin θ

sin θ = 12 / (6√5)

sin θ = 2 / √5   (moving radical to numerator by multiplying by √5/√5)

= 2 / √5     x     √5/√5

= 2√5 / 5

= (2/5)√5

MarathonTraining for a marathon takes work and perseverance. It is not something you can do on the spur of the moment. Preparing for a marathon takes months, particularly if you have never run a marathon before. The official distance of a full marathon is 26.2 miles. In 2005, the average time to complete a marathon in the United States was 4 hours 32 minutes 8 seconds for men and 5 hours 6 minutes 8 seconds for women. Most people who run marathons are not trying to win. Many runners try to beat their own best time. Some compare their time to other runners in the same gender and age group. Some people set time-oriented goals, such as finishing under four hours, while others try to complete the race without slowing to a walk. Many beginners simply hope to finish the marathon.Trainers recommend that beginners maintain a consistent running schedule for six weeks prior to even starting a marathon training program. The purpose of this is to allow the body to adapt to the various physical demands of long-distance running. First-time marathon runners should train by running four days a week for at least four months, increasing distance by no more than ten percent weekly. As race day approaches, runners should taper their runs, reducing the strain on their bodies and resting before the marathon. It is important not to overexert yourself during training because that can lead to a lot of injuries. Most common injuries are spraining of the knees and ankles. These sprains can hinder the training.Before the race, it is important to stretch in order to keep muscles limber. Staying hydrating is also important, but there is a danger in drinking too much water. If a runner drinks too much water, he/she may experience a dangerous condition called hyponatremia, a drop of sodium levels in the blood. During the race, trainers recommend maintaining a steady pace. It is normal to feel sore after a marathon. Light exercise will help sore muscles heal faster.Some people run marathons in pairs or groups. Training for and running with another person or group of people can make the experience more enjoyable and more rewarding. A running partner might be just the motivation you need to show up for an early morning run instead of rolling over to hit the snooze button. And, when you cross the finish line together, you can share the satisfaction of reaching your common goal.Usually, thousands of people sign up and run a marathon. Most people finish the race. The thrill of running a marathon for the first time is unbelievable. The training sessions are harder if you have never run before. But it is unbelievable what ones body can do when one puts their mind to it. Having a good coach to support you makes all the difference in training for a marathon.The health benefits you gain from training are tremendous. Your core muscles grow stronger and you will have tighter thighs and gluts. Your heart will be much stronger and you can maintain lower cholesterol and blood sugar levels. Overall you will look better and healthier.Nothing can explain how people feel when they reach that finish line at the end of the race. All the hard work and months of training feel worthwhile. The feeling of accomplishing something great overtakes you. It is great to run a marathon but it is even greater to finish it.Write a sentence summary of the first paragraph in the text. 90% Attempt 1245678910cIf a criminal sentence is commuted it is doubled.Please select the best answer from the choices providedAnswer is F False Read each sentence below.
