If the area of a sector is 100 ft^2 and the radius of the circle is 22 ft what is the central angle measure for that sector and what is the length of the arc

Answers

Answer 1

Answer:

[tex]\displaystyle \theta=0.413\ rad[/tex]

L= 9.086 feet

Step-by-step explanation:

Area of a Circular Sector

Given a circle of radius r, the area of a circular sector defined by a central angle θ (in radians) is given by

[tex]\displaystyle A=\frac{1}{2}r^2\theta[/tex]

And the length of the arc is:

[tex]L=\theta r[/tex]

We know the area of the sector is 100 square feet and the radius is r=33 ft, thus:

[tex]\displaystyle 100=\frac{1}{2}r^2\theta[/tex]

Solving for θ:

[tex]\displaystyle \theta=\frac{200}{r^2}[/tex]

[tex]\displaystyle \theta=\frac{200}{22^2}[/tex]

[tex]\displaystyle \theta=0.413\ rad[/tex]

The arc length is:

[tex]L=0.413* 22[/tex]

L= 9.086 feet

Natalie is on her school's swim team. Last year, she swam the 300-meter freestyle in 3 2/3 minutes. This year she swam a shorter distance of 200-meter freestlye in 3 minutes. What is her speed for per hour for each hour for each distanc

Answers

Answer:

4909 m/hr

6000 m/hr

Step-by-step explanation:

Last Year :

Distance = 300 m

Time = 3 2/3 minutes

Speed per hour = distance / time

Time in hour = 11/3 ÷ 60 = 0.0611111 hour

300 / 0.0611111 = 4909.0918 m /hr

= 4909 m/hr

This year :

Distance = 200 m

Time = 3 minutes

Speed per hour = distance / time

Time in hour = 3 ÷ 60 = 0.0333333 hour

200 / 0.0333333 = 6000.0060 m /hr

= 6000 m/hr

The cost of a set of DVDs after a 25% markup can be represented by the expression c+0.25c . Simplify the expression.

Answers

Answer: 1.25c

Step-by-step explanation:

The original cost of the DVDs is given as c.

The cost of the DVDs after a 25% markup is: c + 0.25c to show that 25% of c was being added to c to increase the price.

As both numbers in the equation have the same variable attached, they can be added. c is assumed to be 1c when it stands alone.

= c + 0.25c

= 1c + 0.25c

= 1.25c


AB, CD and EF are straight lines.
AB is parallel to CD.
work out the size of angle y.

Answers

Answer:

y = 108°

Step-by-step explanation:

Since, line AB is parallel to line CD,

By the definition of corresponding angles,

m∠FPB = m∠FQD

(2x + 16)° = (3x - 12)°

3x - 2x = 16 + 12

x = 28

(3x - 12) = 3(28) - 12

             = 72°

m∠FQD + m∠EQD = 180° [Linear pair of angles]

72° + y = 180°

y = 180 - 72

y = 108°

Find the value of x in the diagram. Explain how you found the answer.​

Answers

Answer:

x = 65

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180° for third angle

third angle = 180° - (60 + 55)° = 180° - 115° = 65°

65° and x are vertical angles and are congruent, thus

x = 65

Answer:

x = 65 degrees

Step-by-step explanation:

Three angles are marked with their values:  55 and  60 degrees.  Thus, the third interior angle of the left triangle (unmarked) is 180 degrees - (115) degrees = 65 degrees.

This 65 degree angle and x are vertical angles.  Thus, x = 65 degrees.  This plus y form a straight angle, so y = 180 degrees - 65 degrees = 115 degrees.

Answers

The inequality that represents the constraint is as follows;

How to solve inequality?

The inequality to describe the constraints is as follows;

Therefore,

let

x = acre of land use to plant soya beans

y = acre of land use to plant wheat

Therefore,

200x + 500y ≤ 100000

Answer:

200x + 500y ≤ 100000

Step-by-step explanation:

Given ,

The cost of planting  soybeans is $ 200 per acre

The cost of planting wheat is $ 500 per acre

The maximum amount he can spend for planting is $ 100,000


Let's assume

x = acre of land use to plant soya beans

y = acre of land use to plant wheat

We know that ,

If 'a' is the cost spend on unit item and 'b' is the number of items the total cost will be a * b

So the total amount spend for planting will be,

200x + 500y

As the amount spend cannot exceed a maximum of $ 100,000 ,

200x + 500y should be less than or equal to 100,000

Therefore we can mathematically represent it using the inequality  as,


200x + 500y ≤ 100000

Hence, the inequality that represents the constraint is as follows;

200x + 500y ≤ 100000

Priya creates a scatter plot showing the relationship between the number of steps she takes and her heart rate. The correlation coefficient of the line of best fit is 0.88.


1. Are they correlated? Explain your reasoning.

2. Does either of the variables cause the other to change? Explain your reasoning.

Answers

Answer:

Positive correlation exists ;

Number of Steps taken will cause heart rate to increase.

Step-by-step explanation:

Correlation refers to the relationship which exists which exists between two variables. It shows how an increase in one variable affects the other variable. Variables are divided into independent and dependent variables. Correlation may either be positive, negative or non - existent.

Given the correlation Coefficient of 0.88 between heart rate and number of steps taken, the R value being close to 1 depicts a strong positive relationship or correlation.

Correlation between number of steps taken and heart rate.

Yes, The number of steps taken will cause the hear rate to increase. Hence, the dependent variable is is heart rate and it depends on the number of steps taken (independent variable).

1. The number of steps taken is correlated with the hate rate because a correlation coefficient of 0.88, shows a positive strong relationship.

2. The her heart rate is dependent on the number of steps she takes, therefore, number of steps taken causes her rate rate to change.

What is Correlation Coefficient?A correlation coefficient shows how corelated two variables are.Correlation coefficient ranges from -1 to 1.The closer the correlation coefficient is to -1 or 1, the stronger the correlation between two variables.

1. The number of steps taken is correlated with the hate rate because a correlation coefficient of 0.88, shows a positive strong relationship.

Answers

Given:

The total cost of making a daily taco special for a restaurant is represented by the function

[tex]C(t)=2.5t+1[/tex]

Where t is the number of tacos made.

To find:

The total cost change for every taco special the food truck makes.

Solution:

We have,

[tex]C(t)=2.5t+1[/tex]

Here, 1 is a constant because it is free from the variable and 2.5 is the coefficient of t.

It means, 1 represents fixed cost of making tacos but 2.5t changes with respect to t. Thus, 2.5 represents the addition cost of every taco special the food truck makes.

So, $2.5 is the total cost change for every taco special the food truck makes.

Therefore, the correct option is b.

Shen invested in a savings bond for 2 years and was paid simple interest at an annual rate of 2% the total interest that he earned was $28 how much did he invest 

Answers

Answer:

Principal = $700

Step-by-step explanation:

Simple interest = principal × rate × time

Simple interest = $28

Rate = 2% = 0.02

Time = 2 years

Principal = x

Simple interest = principal × rate × time

28 = x * 0.02 * 2

28 = 0.04x

x = 28/0.04

x = $700

Principal = x = $700
