What fraction of the circle would 3 pieces represent?

Answer:

m(slope)=-4

Step-by-step explanation:

the slope is the thing you see before x so in this case y-3=-4x+20 so the slope or m is -4.

The slope of the equation y - 3 = -4 ( x - 5 ) is -4.

Given,

y - 3 = -4 ( x - 5 )

We need to find the slope of this equation.

The equation is given by:

y - b = m ( x - a)

Where (a, b) is a point that the line passes through and m = slope.

We have,

y - 3 = -4 ( x - 5 )

Here we see that the equation is in the form of y - b = m ( x - a).

Where,

(a, b) = (5, 3)

m = -4

We have,

Slope = m

m = -4

Thus the slope of the equation y - 3 = -4 ( x - 5 ) is -4.

Answer: 976m^2

Step-by-step explanation:

An easy way to find the surface area of a prism is to find the area of each side and add them all together.

Area of rectangle:

14mx10m=140m^2

Area of rectangle:

25mx10=250m^2

Since there are 2 of the long rectangles, you multiply by 2:

250m^2x2=500m^2

Area of triangle:

(24mx14m)/2=168m^2

Since there are 2 triangles, you multiply by 2:

168m^2x2=336m^2

Surface Area:

140+500+336=976m^2

Answer:

12*sqrt(3)

Step-by-step explanation:

since it is isosceles its angles are 45, 45, 90, therefore the hypotenuse is 12*sqrt(3).

Step-by-step explanation:

the solution are

x = 1 or x = -15

x^2 + 14x - 15 =0

x^2 + 14x = 15

to write the left hand side as a perfect square we add 49 to both sides :

x^2 + 14x + 49 = 15 + 49

x^2 + 2.x.7 + 7^2 = 64

using the identity (a^2 + b^2) = a^2 + 2ab + b^2

(x + 7)^2 = 64

x + 7 = √64 or x + 7 = -√64

x = 8 - 7 or x = - 8 - 7

= 1 = - 15

Answer:

13

Step-by-step explanation:

Find the scale factor by 39 / 30

Take that times 10

1.3 x 10 = 13

Since the questions states these two shapes are "similar" the side will have identical scale factors.

Divide the longest side of the bigger shape to the smaller shape.

39 / 30 = 1.3

The scale factor is 1.3.

Now, multiply the shortest side if the smaller shape by the scale factor.

10 * 1.3 = 13

Therefore, the length of w is 13mm

Step-by-step explanation:

Answer:

a) This is a continuous random variable because the set of possible values is an interval.

b) Height = 0.5

Graph attached.

c) P(Y≤1) = 0.5

Step-by-step explanation:

a) If the density curve of the outcomes has a constant height, we have a uniform distribution for values between 0 and 2 (outside this range, the density function has a value of 0).

This function is continous and has a value for each real number. The set of possible values has a is an interval between 0 and 2, all with equal probability (the ones that are otuside this interval have 0 probability, so they are not possible values).

b) The height is calculated so that the total area under the density curve has to be equal to 1.

Then, we have to calculate the integral between 0 and 2 of the density function:

[tex]\int\limits^2_0 {U(x)} \, dx =\int\limits^2_0 {H} \, dx =H\int\limits^2_0 dx=H(x_2-x_1)=H(2-0)=1\\\\2H=1\\\\H=0.5[/tex]

The height is H=0.5

(Graph attached)

c) The probability can be calculated by integrating the density function (which is equal to the area under the curve) between 0 and 1, or using the graph.

With the graph, we see that the area is equal to the height (0.5) by the width of the interval (1), so the total area is 0.5 x 1 = 0.5.

The probability P(Y≤1) is equal to 0.5.

Using the uniform distribution, it is found that:

a)

This is a continuous random variable because the set of possible values is an interval.

b)

The height is [tex]\frac{1}{2}[/tex], and the sketch is given at the end of this answer.

c)

P(Y ≤ 1) = 0.5

An uniform distribution has two bounds, a and b.  

The probability of finding a value of at lower than x is:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

In this problem, uniformly distributed between 0 and 2, thus [tex]a = 0, b = 2[/tex].

Item a:

Values in an interval, thus continuous. Discrete are for sample spaces, which is not the case here.

Item b:

The height is:

[tex]h = \frac{1}{b - a} = \frac{1}{2}[/tex]

The graph is sketched at the end of this answer.

Item c:

[tex]P(Y \leq 1) = \frac{1 - 0}{2 - 0} = \frac{1}{2} = 0.5[/tex]

Thus, P(Y ≤ 1) = 0.5.

Answer:

g = number of tickets for goldfish

t = number of tickets for tacky mirrors

s = number of tickets for stuffed tiger

1g + 2t + 1s = 40

5g +     + 1s = 40

2g + 3t         = 40

using the second equatin we can find a value for s

1s = 40 -5g

now substitute in the first equation to get rid of s

1g + 2t + (40-5g) = 40

-4g + 2t         = 0

now use this new equation with equation 3 and solve for one of the values

-4g + 2t = 0

2g + 3t  = 40

multipy the second equation by 2 and then combine

-4g + 2t = 0

 4g + 6t = 80

8t = 80

t = 10  (so it takes 10 tickets to get a takcy mirror)

2g + 3(10) = 40

2g = 10

g = 5  (five tickets to get a goldfish)

s = 40 -5(5)

s = 15  (fifteen tickets for a stuffed tiger)

1(5) + 2(10) + 1(15) (substitute back in the first equation)

5 + 20 + 15

Answer:

14 bags

Step-by-step explanation:

Dimension of lawn : 230 feet by 180 feet

area of rectangle is given by length * width

Since lawn is rectangular area of lawn = 230 feet * 180 feet = 41,400 sq. feet

Given that one bag of fertilizer covers 3000 square feet of lawn.

Thus , to find no. of bags required to cover whole lawn will be

total area of lawn/area which one bag of  fertilizer covers

no. of bags required to cover whole lawn = 41,400 sq. feet/3000 sq. feet

    = 13.8 bags.

As no. of bags cannot be fractional , hence rounding bag to nearest unit place is 14 bags.

Answer:

$50.08

Step-by-step explanation:

Let's use x to represent the lesser expensive hat and 2x to represent the more expensive hat since the more expensive hat is twice the price.

So, our equation would be 2x + x = 75.12

We can combine them together to make 3x.

Then, we make the 3x equal to 75.12

3x = 75.12

Now, we solve it.

Divide both sides by 3 to solve for x.

75.12/3 = 25.04

x = 25.04

Lastly, plug it in for 2x to get the price of the more expensive hat.

2(25.04) = ?

2(25.04) = 50.08

Therefore, the price of the more expensive hat is $50.08
