Answer:
(a) 12π in
(b) 53.5 in
(c) 96 grams
Step-by-step explanation:
In the figure attached, the ornament is shown
(a) four three-quarter circles is equivalent to 4*3/4 = 3 circles. The perimeter of a circle is the total length of the circular portions.
Perimeter of each circle: 2*π*r
The radius is 2 in long, then for 3 circles:
Perimeter = 3*2*π*2 = 12π in
(b) Perimeter of square: 4*side length
The side length of the square is 4 in, then:
Total length of wire needed = 4*4 + 12π = 53.5 in
(c) The wire weighs 1.8 grams per inch, then:
total weight of the ornament = 1.8 grams/in * 53.5 in = 96 grams

The angle measures of J and L are given as follows:
m < J = m < L = 65º.
How to obtain the angle measures?To obtain the angle measures, we must considering that the sum of the measures of the internal angles of a triangle is of 180º.
The internal angles for this problem are given as follows:
<J.<K.<L.Angles J and L are congruent, meaning that they have the same measure, which is obtained as follows:
50 + x + x = 180

Regina kept track of the points she scored during her team’s first eight basketball games. What is Regina’s mean score?
Responses
A 3939
B 1616
C 3737
D 1313
E 17
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16

Answer: The ratio is 18:3
Step-by-step explanation:
Answer: 6 to 1
Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.
18/3
18 can be divided by 3, 6 times so the fraction can be simplified to
6/1 meaning there are 6 players for every coach.

For a dilation centered at the origin with a scale factor of 3/2:
(a) original coordinates → final coordinates
R (-4,6) → R' (-6,9)
S (6,2) → S' (9,3)
T (-6,-4) → T' (-9,-6)
(b) (x, y) → ((3/2)x, (3/2)y)
How to determine a dilation mapping?To determine a dilation mapping, follow these steps:
Identify the center of dilation. This is the fixed point around which the dilation occurs.Determine the scale factor. The scale factor determines how much the image is stretched or shrunk. It can be a positive or negative number, but it cannot be zero.Apply the scale factor to each coordinate. To do this, multiply each coordinate by the scale factor, with the center of dilation as the origin.For example, if the center of dilation is (2, 3) and the scale factor is 2, the dilation mapping can be expressed as:
(x, y) → (2(x-2), 3(y-3))
This means that every point (x, y) is transformed into the point (2(x-2), 3(y-3)) after the dilation.

1. Two of the angles of a triangle measure 15° and 150°. Classify the triangle.
A. Equilateral
B. Scalene
C. Isosceles
Its Isosceles
cause a triangle must always add up to 180 if you are finding the angles and they give you 15 and 150 if you add that you get 165 and i you subtract that from 180 you get 15 and a isosceles has 2 equal angles
Answer:
Isosceles
Step-by-step explanation:
An isosceles triangle is a triangle with two equal sides, as well as two equal angles. So take 150, add it to 15. You get 165. Take 180, then subtract 165. You get 15, and since you know another angle is 15, you have an isosceles triangle.
