Answer:

Perimeter of the sector = (36 + 8π) cm.

Step-by-step explanation:

Formula to find the of an arc of the circle is,

Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]

Here, θ = central angle formed by the arc

r = radius of the circle

Therefore, length of the arc given in the picture = [tex]\frac{80}{360}(2\pi) (18)[/tex]

                                                                                = 8π cm

Perimeter of the sector = Sum of all sides of the sector

                                       = Length of radius + length of the arc + length of radius

                                       = 18 + 8π + 18

                                       = (36 + 8π) cm

Perimeter of the sector is (36 + 8π) cm.

Answer/Step-by-step explanation:

Given two points on a line, (-4, 10) and (0, 2), the slope of the line is calculated as follows:

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Let,

[tex] (-4, 10) = (x_1, y_1) [/tex]

[tex] (0, 2) = (x_2, y_2) [/tex]

Plug in the values

[tex] slope (m) = \frac{2 - 10}{0 - (-4)} [/tex]

[tex] slope (m) = \frac{-8}{4} = -2 [/tex]

Slope = -2

The wrong formula was used. Slope is supposed to be change in y over change in x. Rather the difference of each coordinates was solved and divided by each other, which makes the whole calculation wrong.

Answer:

2 teaspoons for the two frozen cookies

3/4 a cup for the cooking oats

2 cups for the flour

Step-by-step explanation:

First Question

The recipe makes 18 cookies. Divide the cookies by 9, half of the batch, to get 2. Now all you have to do is devide the amount of vanilla extract by 9, it will give you two teaspoons.

1 and 1/2 devided by two since you're devidng the recpie by two to get 9 cookies. A cup is four so 3/4 plus 3/4 equals 6/4. Simplified it'd be 1 and 1/2 or 1 and 2/4.

The recipe already calls for 1 and 1/2 a dozen. All you're doing is multiplying the recipe b two to get 3 dozen cookies. Now focusing our attention to the flour, there is 1 cup for 1 and 1/2. Multiply 1 by 2 since there is already half of the recipe here. 1 and 1/2 + 1 and 1/2 is 3 so there'd be 2 cups. Basically just double the recipe.

The probability that Laura does not win the prize is 0.9657

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

The value of probability lies between 0 and 1

Given data ,

Let the probability that Laura wins be = P ( x )

So , the probability that Laura does not win is = 1 - P ( x )

Let the total number of raffle tickets to be sold is = 350 raffle tickets

The number of tickets Laura bought = 12 raffle tickets

Therefore , the probability that Laura wins the prize =
number of tickets Laura bought / total number of raffle tickets

The probability that Laura wins the prize P ( x ) = ( 12/350 )

Now ,

The probability that Laura does not win is = 1 - P ( x )

The probability that Laura does not win = 1 - ( 12/350 )

The probability that Laura does not win = ( 350 - 12 ) / 350

The probability that Laura does not win = 338 / 350

The probability that Laura does not win = 0.9657

Hence , The probability that Laura does not win the prize is 0.9657

Answer:

Amount got by Natasha = £52

Step-by-step explanation:

Given that:

Ratio of Sushil, Natasha and Fiona's share = 1:4:2

Amount of money received by Sushil and Fiona = £39

Let,

x be the number of times.

x+2x = 39

3x = 39

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{39}{3}\\x=13[/tex]

Share of Natasha = 4x = 4(13) = £52

Hence,

Amount got by Natasha = £52

Given:

The function is

[tex]d(x)=850(0.94)^x[/tex]

To find:

The domain of the function.

Solution:

Domain is the set of input values.

We have,

[tex]d(x)=850(0.94)^x[/tex]

It is an exponential function, with initial value 850 and decay factor 0.94 because 0.94<1.

The exponential functions are defined for all real values of x. So, the domain of exponential function is always the set of all real numbers.

Therefore, the domain of the function d(x) is the set of all real numbers, i.e., R.

Relationship: [tex]y =2.92x+4.23[/tex]

They are not proportional

The value is $33.43

Step-by-step explanation:

Given:

[tex]x = years[/tex]

[tex]y = amount[/tex]

When he retired, the expression is:

[tex](x_1,y_1) = (0,4.23)[/tex]

and the rate (m) is:

[tex]m = 2.92[/tex]

Solving (a): The relationship between y and x

This can be solved using the following point-slope formula:

[tex]y - y_1=m(x-x_1)[/tex]

Substitute values for x1, y1 and m

[tex]y - 4.23=2.92(x-0)[/tex]

[tex]y - 4.23=2.92(x)[/tex]

Make y the subject

[tex]y =2.92(x)+4.23[/tex]

[tex]y =2.92x+4.23[/tex]

Solving (b): Are they proportional?

No, they are not

A proportional relationship is expressed as:

[tex]y = mx[/tex]

By comparing this to [tex]y =2.92x+4.23[/tex]; they have different format

Solving (c): Value in 2010?

First, we determine the value of x in 2010

2000; x = 0

2001; x = 1

-

2010; x = 10

Substitute 10 for x in [tex]y =2.92x+4.23[/tex]

[tex]y = 29.2+4.23[/tex]

Step-by-step explanation:

Triangles And Circles

If a right triangle is inscribed in a circle (or the circle is circumscribed around the right triangle), then the hypotenuse of the triangle is the diameter of the circle.

The right triangle has both legs of known lengths, thus the hypotenuse (the diameter of the circle is):

[tex]d^2=5^2+5^2[/tex]

[tex]d^2=25+25=50[/tex]

[tex]d=\sqrt{50}[/tex]

Since 50=2*25:

[tex]d=5\sqrt{2}[/tex]

Thus the radius of the circle is:

[tex]r=\frac{d}{2}[/tex]

[tex]r=\frac{5\sqrt{2}}{2}[/tex]

[tex]\boxed{r=\frac{5}{2}\sqrt{2}}[/tex]

The age of John is 41 years.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

John is 5 years older than Samantha and Samantha is twice as old as Tim.

And, The sum of their ages is 95.

Now,

Let the age of Tim = x

Then, Age of Samantha = 2x

And, Age of John = 2x + 5

Since, The sum of their ages is 95.

So, We can formulate;

⇒ x + 2x + (2x + 5) = 95

⇒ 5x + 5 = 95

Subtract 5 both side, we get;

⇒ 5x + 5 - 5 = 95 - 5

⇒ 5x = 90

Divide by 5, we get;

⇒ x = 18

Thus, The age of John = 2x + 5

                                   = 2 × 18 + 5

                                   = 36 + 5

                                   = 41

Therefore, The age of John is 41 years.

Let small cups = S

Large cups = L

They bought a total of 8 cups, so S + L = 8

Rewrite as S = 8-L (1st equation)

Then you also have

$3S + $5L = $30 (2nd equation)

Replace the S in the second equation with the first equation:

$3(8-L) + $5L = $30

Simplify:

24 - 3L + 5L = 30

Combine like terms:

24+2L = 30

Subtract 24 from both sides:

2L = 6

Divide both sides by 2:

L = 3

They bought 3 large cups

Since they bought a total of 8 cups, that means they bought 5 small cups ( 8-3=5)

Large = 3 cups, Small = 5 cups

Answer:

Object A will have greater acceleration.

Step-by-step explanation:

Given that,

The mass of object A = 50 kg

The mass of object B = 75 kg

They were pushed with the same amount of force.

We know that, the force acting on an object is given by :

F = ma

Here F is same for both mass

[tex]m_1a_1=m_2a_2[/tex]

Mass and acceleration have inverse relation. It means the object whose mass is less will have greater acceleration. Hence, the acceleration is greater for object A.

Answer:

58 and 60

Step-by-step explanation:

well if we say that x is the first integer

then we have that the next one is

x+2

so we have

[tex]x+(x+2)=118\\\\2x+2=118\\\\2x=116\\\\x=58[/tex]

and the other one is

[tex]x+2=58+2=60[/tex]

Answer:

suppose one of our integers is x. then the next one would be x+2(because they are consecutive). so the equation looks like this :

x + ( x + 2 ) = 118 then we'll have : 2x+2 = 118 then : 2x = 116 .

so x would be 58 and the next one would be 60
