Circle J was dilated to form circle J'. The diameter of circle J is 2 units and the diameter of circle J' is 18 units. What is the relationship between the areas of circle J and circle J'?

Answers

Answer 1

9514 1404 393

Answer:

  circle J' has 81 times the area of circle J

Step-by-step explanation:

The ratio of areas is the square of the dilation factor. That factor is 18/2 = 9, so the dilated circle has an area that is 9² = 81 times that of the original.

O 360 + 140n, for any integer n
O 140 + 360n, for any whole number n
O 140 + 360n, for any integer n

Answers

Answer n 9 Explanation 140 degrees is the measure of each angle and the sum of ... So degrees and radians are related by the following equations 360 2 ... Measure angles in whole number degrees using a protractor.

The measurement of all angles co-terminal with a -220° angle is represented by 140+ 360 n, for any integer number n.

What are Co-terminal angles?

These are the angles which shares the same initial line or terminal side. They are obtained by adding or subtracting 360° from the given angles.

Given, angle is -220° then its one positive co-terminal angle= -220°+360 = 140°

So, 140° is a positive co-terminal angle of -220°.

Therefore, co-terminal angle must be the type of 140°+360° n,

70in.²
84in.²
154in.²
224in.² ​

Answers

Answer:

224

Step-by-step explanation:

the area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex], so for the circle plug in your numbers:

(3.14)([tex]14^{2}[/tex]) = 615.44

divide this by 4 because t=in the picture you only have a fourth of a circle:

615.44 / 4 = 153.86

the formula for area of a trapezoid is [tex]\frac{a + b}{2}[/tex] × h

so plug in your values: [tex]\frac{14+14}{2}[/tex] × 5

you get 70

add 70 and 153.22

70 + 153.22 = 223.22

this can round to 224

A. 12 m
B. 4 m
C. 133 m
D. 245 m

Answers

Answer: C

Step-by-step explanation: I took the test!!

The required distance that the ladder foot away from the base of the wall is √133  meters. Option C is correct.

What are Pythagorean triplets?  

In a right-angled triangle, its side, such as hypotenuse, perpendicular, and base is Pythagorean triplets.

Here,
Let the base length be x,
According to the question, a 13-meter ladder reach, the foot of the ladder is 6 meters.
So, applying the Pythagoras theorem,
13² = 6² + x²
x = √169 - 36
x = √133

Thus, the required distance that the ladder foot away from the base of the wall is √133  meters.

b. What is the probability that between two and six people inclusive want hot peppers?
c. What is the probability that all 15 will want hot peppers?

Answers

Answer:

A.) 0.002980

B.) 0.8335

C.) 0.00000000143

Step-by-step explanation:

The problem can be solved using the binomial probability formula :

P(success) p = 0.3

Number of trials (n) = 15

P(x = x) = nCx * p^x * (1 - p)^(n-x)

A) Exactly 10:

P(x = 10) = 15C10 * 0.3^10 * 0.7^5

3003 * 0.3^10 * 0.7^5

= 0.002980

B) between 2 and 6 people :

Using binomial probability calculator to save time

P(2) + p(3) + p(4) + p(5) + p(6)

0.0915 + 0.170 + 0.219 + 0.206 + 0.147

= 0.8335

C.) What is the probability that all 15 will want hot peppers?

P(x = 15) = 15C15 * 0.3^15 * 0.7^0

= 1 * 1.4348907E−8 * 1

= 0.00000000143

Answers

Answer:   VW < UW < UV

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

Explanation:

The exterior angle is 137, so the interior angle adjacent to that is 180-137 = 43. This is interior angle U of triangle UVW.

Let's find the missing angle W

U+V+W = 180

43+68+W = 180

111+W = 180

W = 180-111

W = 69

We have three three interior angles of triangle UVW

U = 43V = 68W = 69

The longest side is opposite the largest angle, so the longest side is UV

The shortest side is opposite the smallest angle, so the shortest side is VW

The order of the sides from smallest to largest is

VW < UW < UV

Refer to the diagram below.

Step-by-step explanation:

Thus:

Where,

a = x = ???

b = 8

c = 14 (hypotenuse)

Plug in the values

x² + 8² = 14²

x² + 64 = 196

x² = 196 - 64 (subtraction property of equality)

x² = 132

x = √132

x = 11.49 (approximated to nearest hundredth)
