Answer:
∠A=30° and AC and BC is 13 and 7.5 units respectively
Step-by-step explanation:
Given that in a right triangle ABC , right angled at C , if angle B =60 degree and AB =15 units
we have to find the remaining angles.
By angle sum property, sum of angles in right angle is 180°
∠A+∠B+∠C=180°
∠A+ 60°+90°=180
∠A=180°-150°=30°
∠A=30°
As AB= 15
Now by trigonometric ratios we find the other sides of triangle ABC
Hence, ∠A=30° and AC and BC is 13 and 7.5 unitsStep-by-step explanation:

A circular flower bed is 23 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk in square meters. Use 3.14 for π.
Answer: 244.92 m
Step-by-step explanation:
The area of a circle is pir^2. First you will need to find the area of the concrete and subtract the area of the flower bed from that amount. The concrete is 3 feet wide so you will add that to 11.5 (half of the flower bed diameter) to find the radius. 14.5^2 pi is the entirety of the area. Then subtract 11.5^2 pi for the area of the concrete.

Given:
Triangle ABC and triangle DEF are similar triangles.
To find:
The proportion that can be used to find the length of segment DE.
Solution:
We know that the corresponding sides of similar triangles are proportional.
Triangle ABC and triangle DEF are similar triangles. So, their corresponding sides must be proportional.
[tex]\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{AC}{DF}[/tex]
[tex]\dfrac{AB}{DE}=\dfrac{BC}{EF}[/tex]
[tex]\dfrac{4}{DE}=\dfrac{3}{9}[/tex]
[tex]\dfrac{4}{3}=\dfrac{DE}{9}[/tex]
Therefore, the correct option is A.

0.4 repeating as a fraction for a mixed number
Answer:
Step-by-step explanation:
1.Rewrite the decimal number as a fraction with 1 in the denominator
2.Multiply to remove 1 decimal places. Here, you multiply top and bottom by 101 = 10
3.Find the Greatest Common Factor (GCF) of 4 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
so the answer is
0.4= 2/5

What is the answer X/7-3>8
Answer:
x > 77
Step-by-step explanation:
According to order of operations rules, we must carry out division before addition or subtraction. In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:
X/7-3>8
+3 +3
--------------
x/7 > 11
The easiest way in which to solve for x is to multiply both sides of this inequality by 7:
7(x/7) > 7(11), or
x > 77
All numbers greater than 77 are part of the solution set.

Eric was rock climbing. At one point, he stopped and climbed straight down 2 1/2 meters. Then he climbed straight up 6 3/4 meters. Eric was wondering what his change in elevation was after these two moves.Which of the following equations matches the situation above?
Choice a: 2 1/2-6 3/4=?
Choice b: -2 1/2+6 3/4=?
Choice c: none of the above

Answer:
Choice b

Make A the subject of the formula r=√А/3
Answer:a = 9 r^2
Step-by-step explanation:
We need to make a subject of the formula given r = square root a / 3
Given r = √a / 3 -------------1
Now we can find a.
Squaring the given equation 1 we get
So r^2 = (√a / 3)^2
So r^2 = a / 9
To three decimal places, find the value of the first positive x-intercept for the function f(x) = -2cos(x + 1). (6 points)

1.571

-2.571
PLEASE HELP URGENT I AM TAKING IT NOW
I'm not 100% sure about this because this unit confused me but...
if you put it in your graphing calculator or in desmos, you can see that the first positive x -intercept (which is a point that is on the x-axis) is somewhere around one but it's not 1.571!! (other person is wrong!)
that point is (0.571, 0) so it's the first option

Find the area of quarter circle with the radius of 10
Answer: 78.5
Step-by-step explanation:
Formula: A=pi*r^2 or Area = 3.14*radius squared (by two)
A = 3.14*10^2
A = 3.14*100
A = 314
Divide it by 4, because it's a quarter of the circle: A = 314/4
A = 78.5
Answer: 78.5

Which statement is NOT an accurate comparison of the two dot plots?
A) There is a gap from 7 to 11 for Class A and there is no gap for Class B.
B) Class A is clustered around two areas, while Class B is clustered around the center. C) Class A spreads from 4 to 14, while Class B is spread from 3 to 9.
D) The median for both dot plots is 6.
Answer:
D
Step-by-step explanation:
The statement which is not an accurate comparison of the two dot plots is stated as: Option D) The median for both dot plots is 6
What are clusters in data?Clusters are groups in data. Each group is like clustered or grouped around some number, usually the mean of that cluster.
Spread, also called range of a data, tells the difference between the maximum and minimum value of that data, thus showing how much widely is it spread.
Thus, spread = maximum value - minimum value
For this case, we see that there are two clusters for class A and for class B there is only single cluster which is almost separated but not distinctly forming two clusters.
Class A spreads from minimum 4 to maximum 16, thus its spread is 16-4 = 12 units wide.
Class B spreads from minimum 3 to maximum 9, thus, its spread is 9-2 = 6 units wide.
Also, we can see that for class A, there is a gap from 7 to 11.
So all three options A, B and C are correct.
Now, let we find median.
Median is that value which is in mid of ordered (ascending or descending data set).
For class A, we have the data as:
4,4,4,4,4,5,5,5,6,6, 12,13,13,13,14,14
They are total 16 observations. The middle observation pair is 8th and 9th observation, which are 5 and 6
We can take any of the number between 5 and 6, so 5 < median < 6
That means median of class A's data is smaller than 6, thus, not being 6.
Thus, option D is incorrect and we don't need to find median of class B.
Thus, the statement which is not an accurate comparison of the two dot plots is stated as: Option D) The median for both dot plots is 6
