Answer:

the area will change by 1/9

Step-by-step explanation:

from linear to area scale factor you have to square the value

Answer:

It would be 1:9 of the old rectangle area to the new rectangle area.

Step-by-step explanation:

because it's area, you would do [tex](1/3)^{2}[/tex]. Which is 1/9 because you do 1*1 and 3*3.

Answer:

y ≈ 4.3 cm

Step-by-step explanation:

Given 2 secants from an external point to the circle.

The the product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is

3(3 + y) = 2(2 + 6 + 3) = 2(11) = 22, that is

9 + 3y = 22 ( subtract 9 from both parts )

3y = 13 ( divide both sides by 3 )

y ≈ 4. 3 cm ( to the nearest tenth )

5/6 = 0.833

City B: 5, 6, 3.5, 5.5, 4, 6

Mean: 30/6 = 5

|x - mean|: 0, 1, 1.5, 0.5, 1, 1

Answer:

C. 10 ft.

Step-by-step explanation:

Area of 6 sq. ft. which is rectangular. The length is 3 ft and perimeter is l+l+w+w=perimeter. A rectangular shape has 2 sides of the same length and the other two are the same but, a different length the the other two sides.

Equation:

3+3+2+2=10

Answer:

n= 6

Step-by-step explanation:

subtract 3 from both sides of the equation

it should wind up like this:

9-3=n+3-3

plus 3 and minus 3 cancel out, 9 minus 3 equals 6 so then the equation changes to this:

n= 6

Answer:

[tex](x-1)^2+(y+1)^2=0.25[/tex]

Step-by-step explanation:

From the given graph it is clear that the center of the circle is (1,-1) and the circle passing through the point (0.5,-1).

So, radius of the circle is  

[tex]r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]r=\sqrt{(0.5-1)^2+(-1-(-1))^2}[/tex]

[tex]r=\sqrt{(-0.5)^2}[/tex]

[tex]r=\sqrt{(0.5)^2}[/tex]

[tex]r=0.5[/tex]

The radius of the circle is 0.5 units.

The standard form of a circle is  

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where, (h,k) is center and r is radius.

The center of given circle is (1,-1) and radius is 0.5. So, the equation of circle is

[tex](x-(1))^2+(y-(-1))^2=(0.5)^2[/tex]

[tex](x-1)^2+(y+1)^2=0.25[/tex]

Therefore, the required equation is [tex](x-1)^2+(y+1)^2=0.25[/tex].

these are all approximate

======================================

Explanation:

C = pi*d is the formula for the circumference. We know that C = 44 approximately, so,

C = pi*d

d = C/pi

d = 44/3.14

d = 14.01 approximately

d = 14 also approximate

take half of this to get the radius

r = d/2 = 14/2 = 7

Then use this radius to find the circle's area

A = pi*r^2

A = 3.14*7^2

A = 153.86

A = 154  rounding to the nearest whole number

Answer:

Circle's radius

[tex]r=7.00\rm cm[/tex]

Circle's diameter

Circle's area

[tex]a=\pi \times r^2=3.14\times 7^2=154\rm cm^2[/tex]

Step-by-step explanation:

Given information:

Circle's circumference is = [tex]44\rm cm[/tex]

We know,

Circumference of circle [tex]=2\times\pi\times r[/tex]

On substitution,

[tex]2\times3.14\times r=44\rm cm[/tex]

Circle's radius

[tex]r=7.00\rm cm[/tex]

Circle's diameter

[tex]d=2r=2\times7=14\rm cm[/tex]

Answer:

18.1 cm

Step-by-step explanation:

Consider a segment parallel to CD and passing through B.

This segment will form a right-angle triangle with A

It's length would be equal to the length of CD (the missing length)

Height of that triangle:

11 - 4 = 7

CD² = 16² - 7²

CD² = 207

CD = sqrt(207)

AC² = AD² + CD²

AC² = 11² + 207

AC² = 328

AC = 2sqrt(82)

Which is roughly 18.1 cm

Answer:

180

Step-by-step explanation:

The average rate of change, in simplest form, of the function over the interval 1 < x < 5 is 18.

The average rate of change is the change in the slope of the function, it is given by the formula,

[tex]\text{Average rate of change} = \dfrac{y_2-y_1}{x_2-x_1}[/tex]

Given to us

y₂ = f(x₂) = 27

x₂ = 3

y₁ = f(x₁) = 9

x₁ = 2

Substitute the values in the formula,

[tex]\text{Average rate of change} = \dfrac{27-9}{3-2} = 18[/tex]

Hence, the average rate of change, in simplest form, of the function over the interval 1 < x < 5 is 18.

Answer: 3,130

Step-by-step explanation: 2,815 + 315 = 3,130

The population of the animal in 2006 was 2500.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Given that, in 2007, a census counted 2815 of a certain animal. This was 315 fewer than the number counted in 2006.

So, the population of the animal in 2006 is

2815-315

= 2500

Therefore, the population of the animal in 2006 was 2500.

Given:

Given that the angles of the kite.

The opposite angles of the kite measures (3y + 14)° and (y + 50)°

We need to determine the value of y.

Value of y:

We know the property that the opposite angles are equal.

Thus, applying the property, we have;

[tex]3y+14=y+50[/tex]

Subtracting both sides of the equation by y, we have;

[tex]2y+14=50[/tex]

Subtracting both sides of the equation by 14, we get;

[tex]2y=36[/tex]

Dividing both sides of the equation by 2, we get;

[tex]y=18[/tex]

Thus, the value of y is 18.

Answer:

Runner 1,2 and 3 ran at a average speed of 4.67 , 4 and 2.5 miles per hour respectively

Step-by-step explanation:

We can all agree that speed equals distance divided by time and we are asked to find out the average speed of this 3 people.

---Average speed of runner 1

Speed = distance / time

Since he ran 14 miles within 3 hours

S = 14/3

The average speed was 4.67 miles pet hour

---For runner 2,

Speed = distance / time

Since he ran 16 miles in 4 hours,

Average speed = 16/4

= 4 miles per hour

---For runner 3,

Speed = distance / time

Since he ran 15 miles under 6 hours,

Average speed = 15/6

= 2.5 miles per hour
