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.

Which of the following represents the measures of all angles coterminal with a -220° angle?
O 360 + 140n, for any whole number n
O 360 + 140n, for any integer n
O 140 + 360n, for any whole number n
O 140 + 360n, for any integer n
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,

the figure consists of a quarter circle and a parallelogram. what is the area of the composite figure? use 3.14 for . Round to the nearest whole number.
70in.²
84in.²
154in.²
224in.²
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

How far up a wall will a 13-meter ladder reach, if the foot of the ladder is 6 meters away from the base of the wall?
A. 12 m
B. 4 m
C. 133 m
D. 245 m
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.

84
Set up two ratios: 3:4 and x:48. The ratio always stays the same, so the value that you increased the girls by will be equal with the boys. To get from 4 to 48, you need to multiply by 12. So, to get a proportional number of boys, multiply 3 x 12.
The ratio of boys to girls is 36:48. The question is asking how man total, so add. 36 + 48 = 84.
There are 84 total sixth graders.

Elly's Hotdog Emporium is famous for its chilidogs. Elly's latest sales indicate that 30% of the customers order their chilidogs with hot peppers. Suppose 15 customers are selected at random.
a. What is the probability that exactly 10 customers will ask for hot peppers?
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?
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

=========================================================
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 = 69The 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.
Help please! This has to do with the Pythagorean theorem.
Answer:
x = 11.49
Step-by-step explanation:
Apply the pythagorean theorem to find x
Thus:
a² + b² = c²
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)
