Find the measures of the angles given

Answers

Answer 1

Answer:

BCD = 60

ABD - 90

Step-by-step explanation:

BCD)

BC and CD are the same length on in the circle, they are the radius. Therefor, all angles will be the same at 60

ABD)

All angles together are 180

You know 2 Angles, A at 30 and D at 60

180 - 30 - 60 = Angle B

90 = Angle B

Answers

There are 5 blue marbles and 10 total marbles.

The probability of picking blue is the number of blue marbles/ total marbles.

Probability = 5/10 which reduces to 1/2

please help me answer these 2 questions, worth lots of points

Answers

For the first one, to find x, you are going to take that entire side which would equal to 180 and solve. 2x+20+55=180 would then go down to 2x+65=180 once you add the 20 and 55. Then subtract 65 to both sides and divide your final answer 115/2 which is x=57.5. For the second one it’s 4x-2+21=180, then you will subtract 2 from 21 and get 19. After you would subtract 19 by 180 and divide 4 by each side, getting x=40.25 as your final answer.

A teacher is four times as old as a student. In 28 years, the student's age will be half of the teacher's age. How old are they now?
The age of the teacher is
years.
The age of the student is
years

Answers

Here, let the age of student be x and teacher be 4x after 28 years, the teacher is double the age of student. So the age of teacher will be 4x+28 and student will be 2(x+28)
So,
4x+28=2(x+28)
4x+28=2x+56
4x-2x=56-28
2x=28
x=14
Therefore the age of the teacher in present will be
=4x+28
=4*14+28
=84
And age of student will be:
=x+28
=14+28
=42
Hope this helps

The type of data distribution which is shown on the graph of coin toss where, x is the number of heads is symmetric and discrete.

What is data distribution?

The data distribution is a way to represent the values of a set of data or information. The distribution of data is generally represented in a particular order.

In the given graph, the data distribution is shown for the coin toss. The probability P(X) is shown on the y-axis of the graph, and the number of heads is shown on the x-axis.

There are two types of data distribution shown on the graph.

Symmetric - The data distribution shown on the graph is symmetric over x = 1.

Discrete - The data distribution shown on the graph is discrete because the values of X are distinct.

Hence, the type of data distribution which is shown on the graph of coin toss where, x is the number of heads is symmetric and discrete.

Answer:

none of the function pairs are inverses

Step-by-step explanation:

Inverse linear functions will meet all of several requirements:

each is a reflection of the other about the line y=xthe solution of the simultaneous equations in on the line y=xin standard form, the coefficients are swapped (only)the product of the slopes is 1

_____

For these problems, it is probably easiest to look at the last requirement. Each function is given in slope-intercept form, so the slope is simply the x-coefficient.

5) The product of slopes is (-2)(-1) = 2 ≠ 1 . . . NOT inverses

6) The product of slopes is (-1)(1/3) = -1/3 ≠ 1 . . . NOT inverses

7) The product of slopes is (-4/3)(-1/2) = 2/3 ≠ 1 . . . NOT inverses

8) The product of slopes is (3/2)(-5/2) = -15/4 ≠ 1 . . . NOT inverses

If the line through (-2,4)and ) 5,D)is parallel to the graph of y= 3X +4 find the value of d

Answers

Answer:

D = 25

Step-by-step explanation:

For 2 lines to be parallel, they must have the same sloe;

Given the coordinates (-2,4)and (5,D)

Slope = D-4/5-(-2)

Slope = D-4/5+2

Slope = D-4/7

Given the equation y = 3x + 4, comparing to y = mx+b

mx = 3x

m = 3

Hence the slope is 3

Equating the slopes

D-4/7 = 3

D-4 = 3*7

D-4 = 21

D = 21+4

D = 25

Hence the value of D is 25
