Melanie can run around the track 9 times in 28 minutes. At this rate, how many laps can she run in 1 hour and 15 minutes?

Answers

Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

Answer:

A= 2/6 B=3/5 C=12/8

Step-by-step explanation:

every number is a fraction so take the #5 for example, 5= 5/1.then multiply by the given fraction. easy

For number one, a is 2/6 but can be simplified to 1/3 by dividing the denominator and numerator by 2. B is 3/5 and c is 12/8 but we have to turn that improper fraction into a mixed fraction so it becomes 1 4/8 which simplified is 1 1/2

Feng needs to build a rectangular shipping box with a volume of 9 cubic feet. He has two pieces of plywood that measure 2 feet wide and 3 feet long to serve as the bases of the box. How tall must Feng make the box?

Answers

Answer:

54 feet

Step-by-step explanation:

9x3x2=54

Answer:

1.5 feet

Step-by-step explanation:

The box needs to have a volume of 9 cubic feet.

Volume is l*w*h.

2*3*h=9

6*h=9

Divide by 6

h=9/6

h=1.5

Brayden is working two summer jobs, making $21 per hour tutoring and making $10 per hour landscaping. In a given week, he can work a maximum of 12 total hours and must earn no less than $170. If xx represents the number of hours tutoring and yy represents the number of hours landscaping, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer:

2 hours.

Step-by-step explanation:

Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9

= $297 but he wants to work a minimum of hours for a minimum of 270.

Thus we have the inequality:

252 + 9x ≤ 270

9x ≤ 18

x ≤ 2.

So the number of hours he must do clearing tables = 2.

Answer:

The set of two or more inequalities in one or more variables is referred to as a system of inequalities, and the further discussion can be defined as follows:

System of inequalities:

Get y alone on one side of a linear inequality with 2 variables (x,y). Consider the equation that results when the inequality sign is changed to an equality sign. This equation has a line as its graph. A dashed line is drawn if the inequality is strict.

From the question, we know

[tex]21 x+10y \geq 170[/tex] money

[tex]x+y \leq 12[/tex] hours

Inequality [tex]1 : y\geq - \frac{21}{10} x+17\\\\[/tex]

Inequality [tex]2 : y\leq -x+12\\\\[/tex]

and [tex]x=0, y= 0[/tex]

For example

[tex]y = 2 \ \ \ x=10[/tex]

PLES HELPPP MEEEEE After studying the motions of the planets and stars for many years during the 1500s, the Polish astronomer Nicolaus Copernicus concluded that the Earth moved around the Sun rather than the opposite as was commonly believed. How did Copernicus' work affect the field of astronomy? OA. It led to the modern understanding of planetary motion. OB. It helped explain the various phases of the moon. OC. It led to the discovery of galaxies, including the Milky Way. OD. It proved to other scientists that the Earth was not flat. Am Read the two passages.Passage 1Its stunning natural scenery makes the Great Barrier Reef a popular tourist destination. About two million people visit the reef each year. Most of those visitors are domestic tourists. This is largely due to the fact that Australia is so far away from most places. There are lots of different ways to experience the Great Barrier Reef. Visitors can go diving, fishing, swimming, and enjoy water sports. Some people choose to tour the reef by airplane or helicopter, and others may tour the reef by boat. Tourists can take in the spectacular scenery from a small dinghy or a grand superyacht. There are even glass-bottomed boats that let passengers view the underwater wildlife and scenery. Adventurous visitors may seek out one of the handful of havens where they can swim with wild dolphins. One of the major appeals of these activities is that most of them do not require special training or expensive equipment. There is no one way for people to experience the reef. Regardless of the activities people choose, they encounter some of the most stunning maritime scenery on the planet.Passage 2On our visit to the Great Barrier Reef this last summer, we discovered how stunning this natural wonder is. We weren't alone. Thousands of tourists joined us to take in the wonders that the reef offers. Though we were among thousands, many people, like us, were from Australia. It makes sense I guess, as Australia is quite isolated and harder to travel to. We just felt lucky to experience this amazing reef alongside other Australians and people from all over the world. There were so many activities to choose from. We decided to go snorkeling. We also took a ride in a glass-bottomed boat. We saw so many fish on that boat trip, and we even saw a giant stingray! After a long day at the beach and out on the water, we heard what some other tourists had experienced during the day. There was one thing we agreed on: the Great Barrier Reef offered some of the most incredible underwater scenery any of us had ever seen.What information does the reader learn from Passage 1 that is not included in Passage 2? 1 The reader learns about a larger variety of activities people can do to experience the reef.2 The reader learns about a tourist's point of view while visiting the reef and what made it special.3 The reader learns about how glass-bottomed boats were made and why they are exciting for tourists.4 The reader learns about which activities were enjoyable for tourists and which should be avoided.
