Ryan took 12 minutes to type 600 words report. At this rate how many words could he type in 20 minutes

cupoosta [38]

Method 1:

In order to solve for this, we have to find out how many words Ryan can type in one minute first.

$\frac{600 words}{12 minutes}$ can be simplified into $\frac{50 words}{1 minutes}$

(This is just normal simplifying, all you had to do was divide both sides by 12)

Now that we have our rate, $\frac{50 words}{1 minutes}$ , we can figure out how many words Ryan can type in 20 minutes

$\frac{50 words}{1 minutes}$ * 20/20 = $\frac{1000 words}{20 minutes}$

Ryan can type 1000 words in 20 minutes

Method 2:

You can use two fractions in order to solve this equation:

$\frac{600 words}{12 minutes}$ = $\frac{x words}{20 minutes}$

The 'x' on the right is a variable because we don't know what the number is.

Simplify:

$\frac{50 words}{1 minutes}$ = $\frac{x words}{20 minutes}$

Cross multiply:

1 * x = 50 * 20

x = 1000

Ryan can type 1000 words in 20 minutes

Good luck! If you have any questions, just ask :))

Item cost $430 before taxes and the sales tax is $38.70 find a sales tax

natulia [17]

Answer:

sales tax= 9 %

Step-by-step explanation:

sales tax= cost x %tax

38.70 = 430 x %tax

%tax = 38.7/430 = 0.09 = 9 %

Determine whether the geometric series 27 + 18 + 12 + 8 + ... converges or diverges, and identify the sum if it exists.

Ne4ueva [31]

The given geometric series as shown in the question is seen to; Be converging with its' sum as 81

<h3>How to identify a converging or diverging series?</h3>

We are given the geometric series;

27 + 18 + 12 + 8 + ...

Now, we see that;

First term; a₀ = 27

Second Term; a₁ = 2(27/3)

Third term; a₂ = 2²(27/3²)

Fourth term; a₃ = 2³(27/3³)

Thus, the formula is;

2ⁿ(27/3ⁿ)

Applying limits at infinity gives;

2^(∞) * (27/3^(∞)) = 0

Since the terms of the series tend to zero, we can affirm that the series converges.

The sum of an infinite converging series is:

S_n = a/(1 - r)

S_n = 27/(1 - (2/3)

S_n = 81

The average body temperature of all healthy adults is 98.6 F. A doctor takes a random sample of 100 healthy adults and records t

Yuliya22 [10]

Answer:

Explained below.

Step-by-step explanation:

A parameter is a valuable element of statistical analysis. It denotes the characteristics that are used to define a given population. It is used to define a particular attribute of the population. For instance, population mean, population standard deviation, population proportion and so on.

The parameter of interest is the average body temperature of all healthy adults, <em>μ</em> = 98.6°F.

While making a statistical conclusion about the population under study, the parameter value is unknown. This is because it would not be possible to gather data from every single member of the population. So a sample is selected from the population to derive a conclusion about the parameter.

A statistic is the value of the characteristics that are computed using this sample. For instance, sample mean, sample standard deviation, sample proportion and so on.

The statistic is the average body temperature of 100 randoly selected healthy adults, $\bar x=98.2^{o}F$ .

Susan Bought a soccer ball for her brother. She wants to fool him by putting the ball into a box before wrapping it. The balls c

frutty [35]

Answer:

Ball cannot be fit inside the box.

Step-by-step explanation:

Given:

Circumference of ball = 26 inches

Dimension of box = 8.25 in x 8.25 in x 8.5 in.

We need to find the whether ball gets fits inside the box.

First we will find the Diameter of ball.

Circumference of ball is given so we will find radius of the ball.

Circumference of the sphere is equal to 2 times π times radius.

framing in equation form we get;

$2\pi \times r =26\\\\r= \frac{26}{2\pi}= 4.14\ in.$

Now we will find the Diameter of the ball.

Diameter of ball is equal to 2 times radius.

framing in equation form we get;

Diameter of ball = $2\times 4.14 = 8.28\ in$

Now given that two parallel sides of box has dimension which is 8.25 in.

Since Dimension of box is smaller than diameter of the ball.

Hence we can say that ball cannot be fit inside the box.
