how are rates and ratios related?

Answers

Answer 1
Fundamentally, a ratio is a ratio, a rate is a ratio with time as the denominator and a period is the inverse of a rate.

Of course, there are differential forms of these concepts, where it is not a ratio truly, but it is a “ratio” of differential elements.

A moving company charges a $2,000 fee plus $100 per hour. Another moving company charges an $1,800 fee plus $150 per hour. How long is a job for which the two companies' costs are the same?
2 hours
4 hours
3 hours
5 hours

Answers

It would be 4 hours 

Hope I could help :)

Final answer:

The two moving companies' costs would be equal for a job that takes 4 hours to complete.

Explanation:

The cost for each moving company can be represented as a linear equation. For the first company, the cost equation is C = 2000 + 100h and for the second company, the equation is C = 1800 + 150h. We want to know when these two costs are equal, so we can set the two equations equal to each other and solve for 'h' (which represents the number of hours):

2000 + 100h = 1800 + 150h.

Solving for h, you'll find h = 4 hours. This means that the costs of the two companies will be the same if the job takes 4 hours to complete.

Susan and John are buying cold drinks for a neighborhood picnic. Each person is expected to drink one can of soda. Susan says that if you multiply the unit price for a can of soda by the number of people attending the picnic, you will be able to determine the total cost of the soda. John says that if you divide the cost of a 12 pack of soda by the number of sodas, you will determine the total cost of the sodas. Who is right, and why?

Answers

John's method will find you the price of each individual can of soda.Susan's method will find you the total cost of the soda. total number of cost = the number of things x the cost of each thing 

Susan is right. Susan's method helps you find the cost because through her method, you can find the total cost based on the number of people attending. John's method will help determine how many soda packs are needed.

Tyler orders a meal that costs $15, if the tax rate is 6.6%, how much will the sales tax be on Tyler's meal?

Answers

Answer:

The sales tax on Tyler's meal will be approximately $0.99.

Explanation:

To calculate the sales tax on Tyler's meal, you can first find the amount of tax by multiplying the cost of the meal by the tax rate (in decimal form). Then, you can simply add this tax amount to the cost of the meal.

Tax amount = Cost of the meal × Tax rate

Given:

Cost of the meal = $15

Tax rate = 6.6% = 0.066 (in decimal form)

Now, let's calculate the tax amount:

Tax amount = $15 × 0.066

          ≈ $0.99

So, the sales tax on Tyler's meal will be approximately $0.99.

what's 763 thousandths in scientific notation

Answers

Scientific notation is a form of a number that represented with 10^x. This notation will help much when the number is too big or too small because you doesn't need to write all the zero. A thousandth is 1/1000 which means 10^-3. In this case, the scientific notation of 763 thousandths would be:
763 * 10^-3 = 7.63 * 10^-1

The scientific notation of 763 thousandths is [tex]\boxed{7.63 \times {{10}^{ - 1}}}.[/tex]

Further explanation:

Given:

The number is 763 thousandths.

Explanation:

The place values are only natural numbers.

The base ten systems represent the position of a place value.

The first digit from the right is the ones place, the second digit from the right is the tens place, the third digit from the right is the hundreds, the fourth digit from the right is the thousands.

After decimal the first place is the tenth place, the second place is the hundredth and the third place is the thousandth.

763 thousandths in base 10 can be expressed as follows,

[tex]\begin{aligned}763{\text{ thousandths}}&= \frac{{763}}{{1000}} \\&= 763 \times {10^{ - 3}} \\ &= 0.763 \\\end{aligned}[/tex]

The scientific notation of 763 thousandths can be obtained as follows,

[tex]\boxed{0.763 = 7.63 \times {{10}^{ - 1}}}[/tex]

The scientific notation of 763 thousandths is [tex]\boxed{7.63 \times {{10}^{ - 1}}}.[/tex]

Aidan drives to school and back each day. The school is 16 miles from his home. He averages 40 miles per hour on his way to school. If his total trip takes 1 hour, at approximately what speed does Aidan drive home?

17 mph
27 mph
32 mph
56 mph

Answers

Answer:

The correct option is 2.

Step-by-step explanation:

The formula form speed is

[tex]speed=\frac{distance}{time}[/tex]

[tex]time=\frac{distance}{speed}[/tex]

It is given that the school is 16 miles from his home. He averages 40 miles per hour on his way to school. Time taken by Aidan to reach school from the home is

[tex]t_1=\frac{16}{40}[/tex]

Let speed at which Aidan drive home be s. Time taken by Aidan to reach home from the school is

[tex]t_2=\frac{16}{s}[/tex]

It is given that his total trip takes 1 hour.

[tex]\frac{16}{40}+\frac{16}{s}=1[/tex]

[tex]\frac{16s+640}{40s}=1[/tex]

[tex]16s+640=40s[/tex]

[tex]640=40s-16s[/tex]

[tex]640=14s[/tex]

Divide both sides by 14.

[tex]\frac{640}{24}=s[/tex]

[tex]s=26.666667[/tex]

[tex]s\approx 27[/tex]

Aidan return with speed about 27 mph Therefore the correct option is 2.

Last year at this time we had 250 employees. Due to attrition , we lost 12% of our workforce. How many employees are working now

Answers

Answer: There are 220 employees working now.

Step-by-step explanation:

Hi, to answer this question, first, we have to multiply the number of employees by the percentage in decimal form.

12% = 12/100= 0.12 (decimal form)

So, mathematically speaking:

250 x 0.12 = 30 employees less

Finally, we subtract the number obtained to the initial number of employees.

250 -30 = 220 employees.

There are 220 employees working now.

Combine 6x + 2x in like terms

Answers

6x and 2x have the same variable and are raised to the same power. That means that they are like terms and can be combined.

6x + 2x = (6 + 2)x = 8x

So, 8x is the answer.
The answer is 8x. That is because like terms are similar variable parts, and both 6 and 2 are being multiplied by x.
