Answer:

B) 3 radians

Step-by-step explanation:

The arc length is the product of the radius and angle. You have ...

... 3 radians = 1 × angle

so

... 3 radians = angle

_____

Comment on units

The formula is

... s = rθ . . . . . where s is the arc length, r is the radius, and θ is the central angle in radians.

The units of both s and r are units of length, so the units of angle are ...

... (length units)/(length units) = <no units>

That is, "radians" are fully equivalent to "no units."

The trouble with this problem statement is that it expresses "arc length" in units of "radians." This only works if the units of the radius of the unit circle are "no units". Ordinarily, that would not be the case. The length of the radius of the unit circle is usually "one length unit." If the central angle is 3 radians, then the arc length is "3 length units," not "3 radians."

Answer:

18 years after 1996 which is 2014

Step-by-step explanation:

Town M had a population of 30,500 people. It grows by 2%. That means the next year will be 30,500+0.02(30,500)=31,110. The next year will be 31,110+0.02(31110)=31732.2 and so forth.

Town N had 32,500 and grows by 600 each year. That means the next year will be 32,500+600=33,100. The next year will be 33,100+600=33,700 and so forth.

Year      Town M       Town N

1            31,110            33,100

2           31,732.2       33,700

6           34348          36,100

7           35035          36,700

We can see the populations are getting closer but not very fast. Let's try higher numbers.

Year 20 gives 45,321 and 44,500.  We are close. Let's try year 18. We get 43,561.5 and 43,300.

Answer:

21

Step-by-step explanation:

Since Lilly has read 7/8 of her book (aka 147 pages), divide 147 by 7 and you get 21.

This means 1/8=21

Since she has read 7/8 of the book, and the full book is 8/8, 8/8-7/8= 1/8

Meaning she has 1/8 of the book left to read.

As said before, 1/8 =21

Thus, she has 21 pages left to read.

The equation that represents the area of the doghouse base is 21 = x * (x + 4), where x is the width and x + 4 is the length.

Jason is building a doghouse with a rectangular base, where the area is known to be 21 square feet. If the width is x feet and given the length is 4 feet longer than the width, the length can be represented as x+4. As such, we can create an equation representing the area of the rectangular base as:

Area = Width * Length

By substituting the given values, we get the equation:

21 = x * (x + 4).

This algebraic equation can guide the solution to find the possible values of x, that is, the width of the doghouse.

https://brainly.com/question/15556698

#SPJ12

To determine the possible dimensions of the base of the doghouse, use the equation x^2 + 4x - 21 = 0.

To find the possible dimensions of the base of the doghouse, we can use the given information that the area of the base is 21 square feet and the length is 4 feet more than its width.

We can represent the width as x. So, the length would be x + 4.

The equation for the area of the rectangle is length x width.

Substituting the values, we get x(x + 4) = 21.

Simplifying the equation, we can rewrite it as x^2 + 4x - 21 = 0.

This equation can be used to determine the possible dimensions of the base of the doghouse.

Answer:y =0.07272727273 x + 2.587272727

Step-by-step explanation:

Equation of regression line is: y=ax +b

Where, [tex]b=\frac{\sum y\sum x^2-\sum x\sum xy}{n\sum x^2-(\sum x)^2}[/tex]

[tex]a=\frac{n(\sum xy)-\sum x\sum y}{n(\sum x^2)-(\sumx)^2}[/tex]

Here [tex]n =11,\sum y=32.46,\sum x^2=385,\sum x=55,\sum xy=170.3,(\sum x)^2=3025[/tex]

On substituting the values in the formula above for a and b we get:

Answer:

(8, 85) Would make this relationship not a function because every time you count up 1 it goes up 10 and 8 would match to 80 not 85 making 8, 85 the ordered pair would not be on the graph.

Given Sue's speed of 10 miles per hour, we're looking for an ordered pair that does not fit the relationship y = 10x. While (2,20), (5,50), and (6,60) all fit this relationship, the pair (8,85) does not, hence it won't be on the graph.

Sue's speed on her bike is 10 miles per hour. This relationship can be graphed as a straight line in a coordinate plane because the speed remains constant - the distance covered increases uniformly over time. So, for each hour (x), she covers a distance of 10x miles (y). Therefore, we can identify the ordered pair that does not belong on the graph by determining which one does not fit the relationship y = 10x.

Answer:

Approximately 11.99 years

Step-by-step explanation:

This is just a type of problem like finding how long it will take for you to get somewhere.  Like in finding how fast you need to go to go to a place that is 60 miles in one hour.  All you have to do is divide the distance of the star by the speed of light, and you get the amount of time it will take for the star's light to reach the Earth.

The time taken by the light to travel from a star to Earth is required.

It would take 12 years for the light to reach Earth.

Distance of star from Earth = [tex]1.135\times 10^{14}\ \text{km}[/tex]

Speed of light from star = [tex]9.4607\times 10^{12}\ \text{km/year}[/tex]

Time is given by

[tex]t=\dfrac{\text{Distance}}{\text{Speed}}\\\Rightarrow t=\dfrac{1.135\times 10^{14}}{9.4607\times 10^{12}}\\\Rightarrow t=11.996\approx 12\ \text{years}[/tex]

Answer:

[tex]3\frac{13}{20}=3.65[/tex] kg.

Step-by-step explanation:        

Let S be amount of strawberries picked in the afternoon.

We have been given that Sheldon harvest the strawberries and tomatoes in his garden. He picks 1 2/5 kg less strawberries in the morning than in the afternoon and the strawberries picked in morning are [tex]2\frac{1}{4}[/tex] kg.

To find the amount of strawberries picked by Sheldon in the afternoon we will add [tex]2\frac{1}{4}[/tex] and [tex]1\frac{2}{5}[/tex]  :

[tex]S= 2\frac{1}{4}+1\frac{2}{5}[/tex]      

Upon converting our given mixed fractions into improper fraction we will get,

[tex]S= \frac{9}{4}+\frac{7}{5}[/tex]

Now let us have a common denominator.

[tex]S=\frac{9*5}{4*5}+\frac{7*4}{5*4}[/tex]

[tex]S=\frac{45}{20}+\frac{28}{20}[/tex]

[tex]S=\frac{45+28}{20}[/tex]

[tex]S=\frac{73}{20}[/tex]  

[tex]S=3\frac{13}{20}[/tex]  

[tex]S=3.65[/tex]

Therefore, Sheldon picked [tex]3\frac{13}{20}=3.65[/tex] kg of strawberries in the afternoon.  

Sheldon picks approximately 0.85 kg of strawberries in the afternoon.

To find out how many kilograms of strawberries Sheldon picks in the afternoon, we need to subtract 1 2/5 kg from the total he picks in the morning.

Given that Sheldon picks 2 1/4 kg of strawberries in the morning, we can subtract 1 2/5 kg from it:

2 1/4 kg - 1 2/5 kg = 9/4 kg - 7/5 kg = 45/20 kg - 28/20 kg = 17/20 kg.

Therefore, Sheldon picks 17/20 kg or approximately 0.85 kg of strawberries in the afternoon.

Answer:

(a) what is the sample space for this chance process?

If we toss a coin three times then there are total [tex]2^{3}=8[/tex] outcomes

The sample space associated with the given chance process is:

[tex]S= \left \{ HHH,HHT,HTH,HTT,THH,THT,TTH,TTT\right \}[/tex]

(b) what is the assignment of probabilities to outcomes in this sample space?

Since the given sample space has eight outcomes and we know that a fair coin is tosses three times. Therefore, the probability of all the events mentioned in the given sample space is same. Hence we have:

[tex]Probability = \frac{1}{8}[/tex]

When tossing a fair coin three times, the sample space includes all combinations of heads (H) and tails (T). With a fair coin, the probability of each possible outcome (HHH, HHT, HTH, THH, TTH, THT, HTT, TTT) is equal, at 0.125.

When we're discussing the tossing of a fair coin three times, we're delving into the area of probability. (a) The sample space in this scenario is all the possible outcomes we could have. Those outcomes are: TTT, TTH, THT, THH, HTT, HTH, HHT, and HHH (Remember: H represents a head and T represents a tail).

(b) When we talk about the assignment of probabilities, we mean the likelihood of each potential outcome occurring. With a fair coin, it's equally likely to land on heads or tails - a 0.5 chance for each. Therefore, each of the eight possible outcomes has a 1/8 or 0.125 probability of occurring, granted that all outcomes are equally likely. So, for for instance, the probability of getting one head and two tails (HHT, HTH, THH) is 3/8 or 0.375, and similarly for all other cases.

Answer:

Anya rode at 8.5 miles per hour.

Step-by-step explanation:

We have been given that Taylor and Anya live 63 miles apart. One day they left their houses at 8 am and met at 11 am riding toward each other. Taylor rode at 12.5 miles per hour.

We can see that Taylor and Anya met after 3 hours as 11-8=3. This means that both rode their cycles for 3 hours.

Let us find distance covered by Taylor.

[tex]\text{Distance}=\text{Speed*Time}[/tex]

[tex]\text{Distance covered by Taylor}=12.5\frac{\text{Miles}}{\text{hour}}*3\text{ hours}}[/tex]

[tex]\text{Distance covered by Taylor}=12.5*3\text{ Miles}[/tex]

[tex]\text{Distance covered by Taylor}=37.5\text{ Miles}[/tex]

Therefore, Taylor covered 37.5 miles in 3 hours.

Let us find distance covered by Anya in 3 hours by subtracting distance covered by Taylor from total distance of 63 miles.

[tex]\text{Distance covered by Anya in 3 hours}=(63-37.5)\text{ Miles}[/tex]

[tex]\text{Distance covered by Anya in 3 hours}=25.5\text{ Miles}[/tex]

Now let us find speed at which Anya rode bike.

[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]

[tex]\text{Speed at which Anya rode the bike}=\frac{25.5\text{ Miles}}{3\text{ Hour}}[/tex]

[tex]\text{Speed at which Anya rode the bike}=8.5\frac{\text{ Miles}}{\text{ Hour}}[/tex]

Therefore, Anya rode the bike at the speed of 8.5 miles per hour.

Answer:

Quantity of wheat in 2015 is 19.8(1.098)(1.051) tons

Step-by-step explanation:

We are given

A farm grew 19.8 tons of wheat in 2013

In 2013:

quantity of wheat =19.8 tons

In 2014:

The farms's wheat output increased by 9.8% from 2013 to 2014

So, quantity of wheat becomes

[tex]=19.8(1+0.098)[/tex]

[tex]=19.8(1.098)[/tex]

In 2015:

The farms's wheat output increased  by 5.1 from 2014 to 2015

so, it is increased by 5.1 % of 2014 quantity

so, we get

quantity of wheat in 2015 is

[tex]=19.8(1.098)(1+0.051)[/tex]

[tex]=19.8(1.098)(1.051)[/tex]

You can calculate how much 9.8% of 19.8 ton is and then add that to 19.8 and add 5.1 more to know the weight of wheat in tons produced in 2015.

The total output of wheat in tons, in 2015 is 26.84 tons.

In 2014, there was increase of 9.8% wheat production than last year(2013).

Thus,

Production in 2014 = Production in 2013 + 9.8% of production in 2013

9.8% of production in 2013 = [tex]19.8 \times \dfrac{9.8}{100} = 1.9404[/tex]

Production in 2014 = 19.8 + 1.94 = 21.74

Production in 2015 = Production in 2014  + 5.1 tons= 21.74 + 5.1 = 26.84 tons

Thus, the total output of wheat in tons, in 2015 is 26.84 tons.
