Answer: CB=2/3
Step-by-step explanation:
The triangle's angles are 30-60-90 degrees. So This is right triangle.
Let the triangle is ABC. B is right angle=90 degr . A=30 degrees, C=60 degrees
The long side of right triangle is hypotenuse AC=4/3 units.
In right triangle with 30 degr the side CB that is opposite to acute angle 30 degrees is twice shorter than hypotenuse AC
So CB=4/3/2=2/3
Finally using Pithagor theorem we find AB= sqrt( AC^2-CB^2)=
=sqrt(16/9-4/9)=sqrt(12/9)= 2*sqrt(3)/3
2*sqrt(3)/3>2/3 so AB>CB
So the shortest leg of ABC is CB=2/3
Write 9x + 3y = 15 in slope-intercept form.
Answer:
y=−3x+5
Step-by-step explanation:
The equation 9x + 3y = 15 in slope-intercept form is y = -3x + 5 where the slope is -3 and intercept is 5
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be 9x + 3y = 15
Now , the equation can be simplified as
9x + 3y = 15
Divide the equation by 3 , we get
3x + y = 5
Now , the equation of line is of the form y = mx + c , where m is the slope and c is the y intercept
So ,
Subtracting 3x on both sides , we get
y = -3x + 5
So , the equation of line is y = -3x + 5
Hence , The equation 9x + 3y = 15 in slope-intercept form is y = -3x + 5 where the slope is -3 and intercept is 5

find domain and range using interval notation
Hey there! :)
Answer:
D: [8, 12].
R: [-10, -6].
Step-by-step explanation:
Notice that the endpoints of the graph are closed circles. This means that square brackets will be used:
The graphed equation is from x = 8 to x = 12. Therefore, the domain of the function is:
D: [8, 12].
The range goes from y = -10 to -6. Therefore:
R: [-10, -6].
Answer:
D: [8 , 12]
R: [-10 , -6]
Step-by-step explanation:
Well for this parabola domain and rage are acttually limited because of the solid dots you see on the graph.
So first things first, what is range? Well range is the amount of y values on a line or anything in a graph.
And what’s domain? Domain is the amount of x values on a line or whatnot.
So let’s do domain first.
On the parabola the first x value is 8 and the last is 12 so we have to write this in interval notation which is [8 , 12].
Now for range the lowest y value is -10 and the highest is -6 so in interval notation it is [-10 , -6].

Not sure how I would solve this
The first ordered pair is ( -4 , -3 )
The second ordered pair is ( 8, 3 )
=================================================
Explanation:
The first point is (x,-3) where x is unknown. It pairs up with y = -3 so we can use algebra to find x
x-2y = 2
x-2(-3) = 2 ... replace every y with -3; isolate x
x+6 = 2
x = 2-6
x = -4
The first point is (-4, -3)
---------------------------
We'll do something similar for the other point. This time we know x but don't know y. Plug x = 8 into the equation and solve for y
x-2y = 2
8-2y = 2
-2y = 2-8
-2y = -6
y = -6/(-2)
y = 3
The second point is (8, 3)
A retail variety store that advertises extensively by mail circulars expects a sale with 20% probability. Suppose 30 prospects are randomly selected from a city-wide mailing. What is the expected number (mean) of sales of this store from this sample of 30?
Answer:
The expected number of sales of this store from this sample of 30 is 6.
Step-by-step explanation:
For each prospect, there are only two possible outcomes. Either there is a trade, or there is not. Prospects are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
A retail variety store that advertises extensively by mail circulars expects a sale with 20% probability.
This means that [tex]p = 0.2[/tex]
Suppose 30 prospects are randomly selected from a city-wide mailing.
This means that [tex]n = 30[/tex]
What is the expected number (mean) of sales of this store from this sample of 30?
[tex]E(X) = np = 30*0.2 = 6[/tex]
The expected number of sales of this store from this sample of 30 is 6.
The expected number (mean) of sales of this store from this sample of 30 is 6.
Calculation of the expected number or mean:Since A retail variety store that advertises extensively by mail circulars expects a sale with 20% probability. Suppose 30 prospects are randomly selected from a city-wide mailing.
So here the expected mean should be
= 20% of 20
= 6

Two cylindrical cans of beef stew sell for the same price. One can has a diameter of 8 inches and a height of 4 inches. The other has a diameter of 6 inches and a height of 7 inches. Which can contains more stew & is , therefore ,a better buy?
Answer:
Can 1 will contain more stew
Step-by-step explanation:
Can -1diameter= 8
radius=d/2=4
height=4
therefore volume= [tex]\pi[/tex] r2 h= 201.06
Can-2Diameter= 6
radius=d/2=3
height= 7
therefore volume= [tex]\pi[/tex] r2 h= 197.92
The cylindrical can that contains more stew is the first can which has a diameter of 8 inches and a height of 4 inches.
What is the volume of a right circular cylinder?Suppose that the radius of considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
Right circular cylinder is the cylinder in which the line joining center of top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.
The more volume of a can is, the more stew it can store.
For first can:
Height = 4 inches, diameter of base = 8 inches.Since radius = diameter/2, so radius of base = 8/2 = 4 inches.
Thus, volume of first can: [tex]V = \pi (4)^2 (4) = 64\pi \: \rm unit^3[/tex]
For second can:
Height = 7 inches, diameter of base = 6 inches.Since radius = diameter/2, so radius of base = 6/2 = 3 inches.
Thus, volume of first can: [tex]V = \pi (3)^2 (7) = 63\pi \: \rm unit^3[/tex]
Thus, as π > 0, so first can can contain more stew.
Thus, the cylindrical can that contains more stew is the first can which has a diameter of 8 inches and a height of 4 inches.

Answer:
7/16.
Step-by-step explanation:
The first triangle has no shading.
The second triangle has 1/4 shaded.
The third has 3/9.
The fourth has 6/16.
Based on this pattern, we can assume that the number of small triangles in each triangle are going to be squared of numbers, since the first had 1, the second 4, the third 9, the fourth 16. So, the 8th triangle would have 8^2 small triangles, or 64 triangles in total.
The first triangle has no shaded triangles. The second has 1. The third has 3. The fourth has 6. If you study the pattern, the second triangle has 1 more than the previous, the third has 2 more, the fourth has three more. And so, the fifth triangle would have 6 + 4 = 10 triangles, the sixth would have 10 + 5 = 15 triangles, the seventh would have 15 + 6 = 21 triangles, and the eighth would have 21 + 7 = 28 shaded triangles.
So, the fraction of shaded triangles would be 28 / 64 = 14 / 32 = 7 / 16.

Answer:
180 degrees
Step-by-step explanation:
The sum of all the interior angles in a triangle is always equal to 180 degrees.
Answer:
The correct answer is TRUE.
Step-by-step explanation:
Find the measure of x.
Begin by setting up an equation of the five angles equal to 180°.
x + 37° + 41° + 29° + 51° = 180° • The sum of the angles is 180°.
x + 158° = 180° • Add the known values on the left side.
x = 22° • Subtract 158° from both sides.
The measure of angle x is 22°.

At a DBE lecture of 100 students there are 29 women and 23 men. Out of these students 4 are teachers and 24 are either men or teachers. Find the number of women teachers attending the lecture.
Answer:
The number of women teachers attending the lecture is 1
Step-by-step explanation:
Let M denotes men , W denotes women and T denotes teachers.
Number of women = n(W)=29
Number of men = n(M)=23
Number of teachers=n(T)=4
We are given that 24 are either men or teachers.
So,n(M∪T)=24
We are supposed to find the number of women teachers attending the lecture.
n(M∪T)=n(M)+n(T)-n(M∩T)
24=23+4-n(M∩T)
n(M∩T)=3
So,No. of teachers those are men is 3
Total number of teachers = 4
So, the number of women teachers attending the lecture= 4-3 = 1
Hence the number of women teachers attending the lecture is 1
Find the lengths of the remaining sides of the triangle. a = 18 a is 60 degrees b is 30 degrees b = c =
Answer:
b= 10.39
c = 20.79
Step-by-step explanation:
a = 60 °
b = 30°
c= 180-(60+30)
c = 180-(90)
c = 90°
Length facing angle a = 18
Let's look for length facing angle b
b/sinb = a/sin a
b/sin 30 = 18/sin 60
b =( 18 * sin30)/sin 60
b = (18*0.5)/0.8660
b = 9/0.8660
b= 10.39
Let's look for c
c/sin c = a/sin a
c/sin 90 = 18/sin 60
c = (18 * sin 90)/sin 60
c =18/0.8660
c = 20.79

Previous 20 Two groups leave on different flights from the same airport. Group A flies 200 miles due south, then turns 68° toward west and flies 75 miles. Group B flies 75 miles due north, then turns 51° toward east and flies 200 miles. Which group is farther from the airport?
Answer:
Group B is farther from the airport.
Step-by-step explanation:
To find the distance of each group to the airport we can use the law of cosines in the triangle created with the two movements done and the resulting total distance.
Law of cosines:
[tex]c^2 = a^2 + b^2 - 2ab*cos(angle)[/tex]
For group A, we have the sides of 200 miles and 75 miles, and the angle between the sides is (180-68) = 112°, so the third side of the triangle is:
[tex]c^2 = 200^2 + 75^2 -2*200*75*cos(112)[/tex]
[tex]c^2 = 56863.198[/tex]
[tex]c = 238.46\ miles[/tex]
For group B, we also have the sides of 200 miles and 75 miles, and the angle between the sides is (180-51) = 129°, so the third side of the triangle is:
[tex]c^2 = 200^2 + 75^2 -2*200*75*cos(129)[/tex]
[tex]c^2 = 64504.612[/tex]
[tex]c = 253.98\ miles[/tex]
The distance from group B to the airport is bigger, so group B is farther from the airport.
Find the inverse of the function f(x)=4+ \sqrt{x-2}
Answer:
y = (x - 4)² + 2 , x ≥ 4.
Step-by-step explanation:
Finding the inverse of
f(x) = 4 + √(x - 2)
Begin by swapping the x and y variables in the equation:
x = 4 + √(y - 2)
Subtract 4 from both sides:
x - 4 = √(y - 2)
Square both sides:
(x - 4)² = y - 2
Add 2 to both sides to get your equation:
y = (x - 4)² + 2
However, the domain restriction also needs to be included since the question involves finding the inverse of a square root function. In this case, the domain restriction would be x ≥ 4.
The surface area of a cube may be found using the formula A=6s^2. What is the edge length of a cube with a surface area of 81 cm^2? Round your answer to the nearest tenth.
Answer: s = 3.7 (rounded 3.67 to the nearest tenth)
Step-by-step explanation:
Surface Area = 81 cm^2
Surface Area of the cube = 6s^2
A = 6s^2
81 = 6s^2
S^2 = 81/6
S = 3.67
