Manuel earns $7.25 per hour helping his neighbor. Last month he earned $348. Choose the correct equation and solution which determines the number of hours, h, Manuel worked.

Answers

Answer:

Number of hours= 48 hours

Step-by-step explanation:

Giving the following information:

Hourly rate= $7.25

Total earned= $348

To calculate the number of hours worked, we need to use the following formula:

Total earned= hourly rate*number of hours

number of hours= total earned / hourly rate

number of hours= 348 / 7.25

number of hours= 48 hours

A 25 foot ladder is set against the side of a house so that it reaches up 15 feet. If Camden grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 12 ft.) Round to the nearest tenth of a foot.

Answers

Answer:

The ladder will reach a height of 9.8 foot

Step-by-step explanation:

Given

Initial Position

[tex]L = 25ft[/tex] --- Length of the ladder

[tex]h = 15ft[/tex] --- height against the wall

New position

[tex]L = 25ft[/tex] --- Length of the ladder

[tex]B = 3ft[/tex] --- 3 feet farther from the wall

Required

Determine the new height the ladder will reach

The question is illustrated using the attached image.

Where

[tex]\triangle ABC[/tex] represents the initial position of the ladder

[tex]\triangle DBE[/tex] represents the new position of the ladder

The new height is represented with BD

Using Pythagoras theorem on [tex]\triangle DBE[/tex]

[tex]DE^2 = BE^2 + BD^2[/tex]

[tex]BE = BC + CE = 20 + 3 = 23[/tex]

[tex]BD = x[/tex]

[tex]DE =25[/tex] --- length of the ladder

So, the expression becomes

[tex]25^2 = 23^2 + x^2[/tex]

[tex]625 = 529 + x^2[/tex]

Collect like terms

[tex]x^2 = -529 + 625[/tex]

[tex]x^2 = 96[/tex]

Take positive square roots of both sides

[tex]x = \sqrt{96[/tex]

[tex]x = 9.8ft[/tex] --- approximated

Answer:

9.8 FT

he levels of mercury in two different bodies of water are rising. In one body of water the initial measure of mercury is 0.05 parts per billion (ppb) and is rising at a rate of 0.1 ppb each year. In the second body of water the initial measure is 0.12 ppb and the rate of increase is 0.06 ppb each year.

Which equation can be used to find y, the year in which both bodies of water have the same amount of mercury?

0.05 – 0.1y = 0.12 – 0.06y
0.05y + 0.1 = 0.12y + 0.06
0.05 + 0.1y = 0.12 + 0.06y
0.05y – 0.1 = 0.12y – 0.06

Select the correct answer.Monty is writing an argumentative text about not having exotic animals as pets. He needs help clarifying his claim in the introductory paragraph. Read an excerpt and notice his claim in bold.For years, human beings have been fascinated by wild animals. We visit zoos to attain some type of intimacy with these animals in their new homes. We sit through shows watching them perform tricks and depending on the animal, we get to pet them. All these experiences are educational for many. However, some peoples fascination with these animals has grown to the point that they desire to have these animals as pets. Exotic animals are becoming popular, and I wonder if they make good pets.Exotic animals are meant to live in their natural habitats. If they are not in their natural homes, then they should be in controlled settings such as zoos. The average person is not equipped to care for them in a typical home. Experts estimate that approximately 20,000 exotic wild cats are living as pets in the United States. Sadly, that is almost more than the number of tigers that exist in their natural environment. In states such as Texas, people must have a license to own wild animals such as tigers, however, the state does not have regulations to guarantee the protection of those animals once they have been bought.Caring for exotic pets is extremely costly and can become dangerous. Annual food costs for one tiger cub can cost up to $6,000. These cubs can even weigh up to 500 pounds in a just a few short months and become strong enough to overpower the average adult. These animals require plenty of space to roam and feel comfortable. Luckily, when pet owners are worried about not doing a good job raising these animals, there are pet sanctuaries that are willing to take the animals and care for them.Which statement below best serves as a claim to replace Montys current claim?A. Exotic pets are not ideal for everyone.B. The popularity of exotic pets is becoming alarming and must stop.C. Wild animals are becoming increasingly popular.D.
