A long-distance athlete can run 12 kilometer in 3 minutes. How many kilometers can he run in an hour?

1/2 km 3/60 hr=1/2×60/3 its a yes or no question

Answers

Answer 1

If a long run athlete can run 1/2 km in 3 minutes then he can run 10 km in an hour.

Given, a long distance athlete can run 1/2 kilometer in 3 minutes.

How much distance can he cover in an hour = ?

How quickly something or someone is moving is determined by their speed. If you know how far an object has traveled and how long it has taken, you can calculate its average speed. Speed equals distance times time, according to the speed formula. Knowing the units for distance and time will help you determine what the units are for speed.

Time = 60 minutes.

we know that 3 minutes = 1/2 km

therefore, distance covered in an hour = 1/2 ÷ 3/60

= 1/2 × 60/3

= 1/2 × 20

= 10

distance covered in an hour = 10 km.

hence we get the distance covered by the athlete in an hour as 10 km.

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

Mr raymond teaches dance he has 18 6th graders students and 24/7 grader students he wants to put the students in equal groups each group will have students of only one grade level how many students should be in each group how many of each group will be there very nice thank you

Answers

Using greatest common factor (GCF), Mr. Raymond should put 6 students in each group. If that happens, he will have 3 groups of 6th graders and 4 groups of 7th graders.

The greatest common factor (GCF) of a set of numbers is defined as the largest common positive integer that divides each number into equal parts with zero remainder.

If Mr. Raymond has 18 6th graders students and 24 7th grader students he wants to put in equal groups wherein each group will have students of only one grade level, find the GCF of 18 and 24 to find how many students he will put in each group.

18 : 1, 2, 3, 6, 9, 18

24 : 1, 2, 3, 4, 6, 8, 12, 24

GCF = 6

Hence, he should put 6 students in each group.

Dividing each level of students to groups of 6.

6th graders = 18/6

The area of a blue circle is 15 square yards less than five times the area of a tan circle. The blue circle has an area of 1,335 square yards. Use approximation to find the radius of the tan circle.

Answers

Based on the given task content, the approximate radius of the tan circle given the area of the blue circle is 9.27 yards.

Area of a circle

Area of the tan circle = xArea of the blue circle = (5x - 15) Area of blue circle = 1,335 square yards

1,335 = 5x - 15

Add 15 to both sides

1,335 + 15 = 5x

1,350 = 5x

divide both sides by 5

x = 1350/5

x = 270 square yards

Area of the tan circle = πr²

270 = 3.14 × r²

270 = 3.14r²

divide both sides by 3.14

r² = 270 / 3.14

r² = 85.98726114649681

r = √85.98726114649681

Approximately,

r = 9.27 yards

Write each expression as a single natural logarithm. ln 9+ln 2

Answers

We have expression ln 9+ln 2 as a single natural logarithm ln 18

What is a natural logarithm?

A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.

Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x. When adding parentheses for clarity, the values ln(x), loge(x), or log (x). In order to avoid ambiguity, this is notably done when the argument to the logarithm is not a single symbol.

The power to which e would need to be raised in order to equal x is the natural logarithm of x.

For instance, e2.0149... = 7.5, thus ln 7.5 equals 2.0149.

Since e1 = e, the natural logarithm of e itself, or ln e, is equal to 1, while the natural logarithm of 1 is 0, since e0 = 1.

We have been asked to express ln 9+ln 2 as a single natural logarithm.

⇒ ln 9 + ln 2

⇒ ln (9) = ln (2)

Use the quotient property of logarithms

⇒ ln (9 × 2)

⇒ ln 18

Finally, we have expressed ln 9+ln 2 as a single natural logarithm ln 18

b) if Kathy has $35, how much will change will she get back after buying the album and paying tax​

Answers

Tax levied is $4.17 if the price of album is $27.80.

Kathy will get $3.03 after buying the album and paying the tax.

What is tax?

A tax is a mandatory financial charge or other sort of levy that is placed on a taxpayer by a governmental entity in order to pay for public services and other expenses.

The total amount is calculated by adding the tax on the cost of product or service.

How are Total Amount and Tax related?

The pre-tax price of an item must first be multiplied by the sales tax percentage once it has been translated to a decimal form in order to determine the amount of sales tax that will apply to the purchase. To determine the item's Total Amount, the sales tax must be computed and then added to the pre-tax price.

a) Given data: Tax%=0.15 of cost of album

Selling Price=$27.80.

Tax=Tax%×Selling Price

=0.15×27.80

=$4.17

b) Given data: Amount given by Kathy = $35

Tax=$4.17

Total Amount = Selling Price + Tax

=$4.17+$29.80

=$31.97

Amount left can be calculated by subtracting the amount given by Kathy from the Total Amount.

Amount=$35-$31.97

The function is given as

g(x)= x^ square root of 1+x

So, we have

g(x) = x^(√x+1)

Calculate g(-x)

So, we have

g(-x) = -x^(√-x+1)

Evaluate

g(-x) = -x^(√-x+1)

Calculate -g(x)

So, we have

-g(x) = -x^(√x+1)

In the above computations;

g(x) does not equal g(-x) and -g(x)

We must invest $6294.256 if we want exactly $ 8000 after four years.

The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously, after t years is-

[tex]A = Pe^{rt}[/tex]

Here, we are given that rate of interest = 6% and we need exactly $8000 after four years.

Thus r = 6/100 = 0.06 and t = 4

Putting the values in the compound interest formula we get,

8000 = P[tex]e^{(0.06*4)}[/tex]

8000 = P[tex]e^{(0.24)}[/tex]

P[tex]e^{(0.24)}[/tex] = 8000

[tex]e^{(0.24)}[/tex] = 1.271

⇒  1.271P = 8000P

= 8000/ 1.271P

= 6294.256
