Answer:
Area = 0.785 yrd
Circumference = 12.56 yrd
Step-by-step explanation:
Diameter = 1 yrd
Area of a circle = pi times the radius squared
A = 3.14 (1/2)^2
A = 0.785
Circumference of a circle = 2 times pi times the radius
C = 2(3.14)(1/2)
C = 12.56

Answer:
x is less than or equal to 3
Step-by-step explanation:
subtract three from both sides which will give you 2x is greater than or equal to -6. then divide by -2 on both sides to isolate x (dividing by a negative number flips the sign and a negative divided by a negative equals a positive) so then you get x is less than or equal to 3

In the following diagram, medians AD and BE intersect at F. Which of the following segments would not be true
1) ECD~ACB
2) EF= 1/2EB
3) ED||AB
4) the median drawn from C would pass through F
Answers
The segment that is false is (2) EF= 1/2EB
The median lines of a triangle always meet at a point.
This means that the line from point C is true (option 4 is true)
The median divides the side lengths of the triangle into equal segments.
However, the centroid at point F do not divide line EB into equal segments
This means that:
The equation EF= 1/2EB is false
Hence, the segment that is false is (2) EF= 1/2EB

Lu is making a quilt that is 20 squares wide and has 15 rows. The border of the quilt is made by using each toy design equally as often. There are a total of 6 toy designs. Each square can hold one design. How many of each design does she use for the border?
Answers
Answer:
Out of 6 designs 4 designs will have 12 repetitions and 2 designs will have 11 repetitions.
Or
On the average each design will be repeated 11.67 times.
Step-by-step explanation:
HEre the width = 20 and length = 15
The perimeter = 2(l+b)
= 2( 20+ 15) = 70
The border of the quilt has 70 squares. Each square can have 1 design and there are 6 designs
Number of repetitions for each design = 70/6= 11. 67
6 designs can have 11 repetitions for 66 boxes= 6 *11= 66
4 squares will be left out. 70-66= 4
4 design can have additional repetition.
Meaning out of 6 designs 4 designs will have 12 repetitions and 2 designs will have 11 repetitions.
Or
On the average each design will be repeated 11.67 times.

can you say a triangle with equal angles of 60 is equilateral
Answers
Answer:
Not really
Step-by-step explanation:
NOT NECESSARILY would a triangle be equilateral if one of its angles is 60 degrees. To be an equilateral triangle (a triangle in which all 3 sides have the same length), all 3 angles of the triangle would have to be 60°-angles; however, the triangle could be a 30°-60°-90° right triangle in which the side opposite the 30 degree angle is one-half as long as the hypotenuse, and the length of the side opposite the 60 degree angle is √3/2 as long as the hypotenuse. Another of possibly many examples would be a triangle with angles of 60°, 40°, and 80° which has opposite sides of lengths 2, 1.4845 (rounded to 4 decimal places), and 2.2743 (rounded to 4 decimal places), respectively, the last two of which were determined by using the Law of Sines: "In any triangle ABC, having sides of length a, b, and c, the following relationships are true: a/sin A = b/sin B = c/sin C."¹
Step-by-step explanation:
A triangle with three equal interior angles is called an equiangular triangle. In an equiangular triangle has three. equal sides, and it is the same as an equilateral triangle.

The value of sin(θ) is -5√41/41 because sin is negative in the fourth quadrant option (A) -5√41/41 is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
cos(θ) = 4√41/41
As we know cos is the ratio of the side adjacent to the angle to the hypotenuse.
cos(θ) = adjacent/hypotenuse
From the Pythagoras theorem:
hypotenuse² = opposite² + adjacent²
41² = opposite² + (4√41)²
After calculating:
opposite = √1025
opposite = -5√41 (because sin is negative in the fourth quadrant)
sin is the ratio of the opposite to hypotenuse:
sin(θ) = -5√41/41
Thus, the value of sin(θ) is -5√41/41 because sin is negative in the fourth quadrant option (A) -5√41/41 is correct.

Answers
Answer:
m∠2=78°
Step-by-step explanation:
∡2=90°-∡1=90°-12°=78°, therefore ∡2=78°
The measure of ∠2 is 78°.
We have two angles ∠1 and ∠2 which are complementary angles such that ∠1 = 12°.
We have to find the measure of ∠2.
What are Complementary angles ?When the sum of two angles is equal to 90 degrees, they are called complementary angles.
∠X + ∠Y = 90
According to the question, we have -
The measure of angle ∠1 = 12°.
Assume that the magnitude of ∠2 is x.
Then -
∠ 1 + x = 90°
x = 90° - ∠1
x = 90° - 12°
x = 78°
Hence, the measure of ∠2 is 78°.
