A rectangular yard has a width that is 10 feet longer than the width . If the the area of the yard is 600 squared feet , find the dimension of the yard

Answers

Answer:

length = 30 feet and width = 20 feet

Step-by-step explanation:

Let l is length and b is width of a rectangular yard. The area of a rectangle is given by :

A = lb ..(1)

A rectangular yard has a length that is 10 feet longer than the width.

length, l = 10+b ...(2)

ATQ,

Put the value of l in equation (1),

[tex](10+b)b=600\\\\10b+b^2=600\\\\b^2+10b-600=0\\\\b^2+30b-20b-600=0\\\\b(b+30)-20(b+30)=0\\\\(b+30)(b-20)=0\\\\b=-30\ \text{feet}\ \text{and}\ b=20\ \text{feet}[/tex]

Width can't be negative. The width is 20 feet.

Put the value of b is equation (2),

l = 10+20

l = 30 feet

Hence, the length and width are 30 feet and 20 feet.

find the original price of a pair of shoes if the sale price is $40 after a 60% discount

Answers

Answer:

Thus, the original price of the pair of shoes was $100.

Step-by-step explanation:

Percentages

After a 60% discount, the sale price is now valued at 100-60=40% of its original price.

If the sale price is $40, then the original price is calculated as

$40 / 40 * 100 = $100

Thus, the original price of the pair of shoes was $100.

Verify applying 60% discount:

$100 - 60*$100/100 =  $40

A goat is tied to the corner of a rectangular shed in a large field full of grass. The rope is 2 yards long and a plane view (from above) of the shed and field is shown below. Use this information for Parts A and B below.
Part A: Calculate the area of grass that the goat can eat.
Part B: What length of rope would enable the goat to eat 30 square yards of grass? Show all your reasoning.

Answers

Answer:

9.42 yd²3.57 yd

Step-by-step explanation:

Part A

The area of circle with radius of 2 yd (the length of the rope) is:

A = π*r² = 3.14*2² = 12.56 yd²

Since 1/4 of the circle is occupied by the shed, the area of the grass is:

12.56*3/4 = 9.42 yd²

Part B

Let the area be 30 yd², finding the r as per above formula:

3/4*3.14*r² = 30r² = 30*4/3*3.14r² = 12.74r = √12.74r = 3.57 yd

BRAINLIEST!!!!!!!!!!!!!!The Online Child Parents should seriously think about the online life of their children. "Online life" refers to the activities people are involved in while using the Internet. Today's teenagers have grown up with technology and the Internet. They are becoming more knowledgeable about technology, sometimes more so than their parents. These days, teenagers spend a lot of their time on the Internet using social networking sites. Other times, teenagers enjoy spending time with their school friends or playing sports. Social networking sites provide the perfect place for teenagers to exercise their freedom. In addition, these teenagers also find a venue to express themselves openly with their online friends. They post pictures of themselves and share thoughts for the whole world to see. The problem is that the teenagers are not always aware that their images and words on the Internet are permanent. Teenagers may not be aware that people often use fake identities on the Internet and give false information. In addition, problems with "friends" on the Internet can have real-life consequences. And just like a real child, the online child needs the parents to tell him or her how the world (of the Internet) works. The teenagers need to learn critical-thinking skills applicable to real life and Internet life. While educating their children on the risks of the Internet, parents should also demonstrate trust and allow their children enough space to learn on their own. For example, parents can let their children know that they will be making frequent checkups on their children's social networking page. That way, children can learn to practice caution when they post content on the Internet, while still retaining a feeling of independence. Parents can take the check-up time to teach their children about safe online habits.Which sentence could be added to the end of the introduction to strengthen it? A.
