The map of a biking trail is drawn on a coordinate grid. The trail starts at P(−6, 3) and goes to Q(3, 3). It goes from Q to R(3, −4) and then to S(6, −4). What is the total length (in units) of the biking trail?

Answers

Answer:

total length = 19 units

Step-by-step explanation:

Notice that the distance between the extremes of the first segment of the trail, is a horizontal segment of 9 units length.

The second segment from (3,3) to (3, -4) is  vertical one of length 3 - -4 = 7 units.

The third segment of the trail  from (3, -4) to (6, -4) is another vertical segment of length 6=3 = 3 units.

Therefore,the total length of the trail is 9 + 7 + 3 = 19 units

Boxes of Valentine’s Day chocolate truffles come in a variety of sizes. The dimensions of the box you decided to purchase are 15 inches by 12 inches by 1.5 inches. If each truffle in this box has a volume of 2 cubic inches, how many truffles are included in the box?
A.

Answers

Answer:

135.

Step-by-step explanation:

Volume of the box = 15*12*1.5

= 270 in^3.

So the number of truffles = 270 / 2

= 135.

The number of truffles in the box is 135.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The dimensions of the box = 15 inches x 12 inches x 1.5 inches.

The dimension of each truffle = 2 cubic inches

The number of truffles included in the box.

= (15 x 12 x 1.5) / 2

= 270/2

= 135

Thus,

The number of truffles in the box is 135.

The sum of 88 elephants and x
elephants is 145 elephants.

Answers

57 elephants = x
Hope this helps

Answer:

x=57

Step-by-step explanation:

To solve this problem we need to make an equation to use to solve x.

The sum of 88 and x will equal 145 so the equation will look like this, 88 + x = 145.

Whatever x is, it has to add with 88 to make 145 so we have to use reverse operations.

The opposite of addition is subtraction so we subtract 88 from 145 like so. 145 - 88 = 57, which means x = 57.

Mrs. Doshi is sewing decorative banners. Each banner uses yards of fabric. Mrs. Doshi has 2yards of fabric. How many banners can she make?

А.

7 banners

B. O None of these

C

6 banners

DO 2 banners

E. O 3 banners

Answers

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but let's reframe it and try to solve it.

Let's assume that each banner uses 1/3 yards of fabric and that Mrs. Doshi has 2yards of fabric. To get the number of banners that she can make, we would have to divide the amount if yards that Mrs Doshi has by the amount of yards of fabric that each banner will use. In this case, this will be:

= 2 ÷ 1/3

= 2 × 3

= 6 yards

It's important to remember that everybody makes mistakes. I guess we both did in this case.' "Write a paragraph explaining what these lines reveal about Mr. Berry. Use details from the story to support your answer.Here is the whole story in case you want it:The Case of the Missing Library Book Mr. Berry, the librarian, had a reputation for being strict and for never making mistakes. He maintained complete order in the library and could tell immediately if a book was missing or misplaced. He did not say much. This struck fear into the students. They always said that Mr. Berry did not have to talk. When someone was careless with a book, the look on Mr. Berrys face told that person everything he or she needed to know. All of this contributed to making Tom feel terrible about losing the copy of Animal Farm that he had borrowed nearly four weeks earlier. It was as if the book had disappeared from the face of the earth. In fact, Tom had completely forgotten about the book until he received an overdue notice from Mr. Berry through the mail. Tom did not look forward to facing the librarian directly. When he left for school that morning, he felt as if he were going to his execution. Toms fear increased with each tick of the clock. It was already fourth period by the time he talked himself into going to see Mr. Berry. As he walked to the library, his palms were sweating and he felt as though he had butterflies performing acrobatics in his stomach. When he walked through the doors, he saw that the library was deserted, except for Mr. Berry. Tom was happy that nobody would witness the embarrassing scene that was sure to erupt. Upon seeing Tom, Mr. Berry said, "Oh Tom, I owe you an apology. I guess I made a mistake. I didn't realize that you had already returned Animal Farm." At first, Tom didn't know what to say, and then, much to his surprise, he found himself telling Mr. Berry that he hadn't returned the book, that he'd lost it, and that he'd looked all over for it but couldn't find it. Tom could not stop the words from coming out of his mouth. When Tom finished, Mr. Berry smiled and said, "Well, somebody found it and returned it. That's the important thing. It's important to remember that everybody makes mistakes. I guess we both did in this case." Tom smiled too; he felt relieved. As he made his way back to class, he decided that he really liked Mr. Berry and that he would try to use the library more often. -2x - y = 1-6x=3y+3 Solve For X.
