Step-by-step explanation:

The first step is to calculate x

because it's a straight line all angles must add up to 180

we can write the following equation

(3x+94)+(x+30)+(2x-4)=180

6x+120=180

6x=60

x=10

Now to solve for COD just plug in 10 for x+30

10+30=40

Answer:

15

Step-by-step explanation:

The GCF of 25 and 35, is 15

Answer:

5

Step-by-step explanation:

Use the L method or the tree method. If you go through your numbers and see which number can divide both 25 And 35, you should find 5 because both of them end in 5 Since anything is divisible by 5 if it has a 0 or a 5 as the ones.

If you also needed help with the LCM, it is, keep one of the fives and divide the other to get rid of the five, then multiply them all together, so 25 * 7 = 175.

Answer: 7/24

This question is incomplete, the complete question is;

In the game of Pick-A-Ball without replacement, there are 10 colored balls: 5 red, 2 white, and 3 blue. The balls have been placed into a small bucket, and the bucket has been shaken thoroughly. You will be asked to reach into the bucket without looking and select 2 balls. Because the bucket has been shaken thoroughly, you can assume that each individual ball is selected at random with equal likelihood of being chosen.

Now, close your eyes! Reach into the bucket, and pick a ball. (Click the red Pick-A-Ball! icon to simulate reaching into the bucket and drawing your ball.)

a) What is the probability of selecting the color of ball that you just selected? (Round your answer to four decimal places.)

Don't put your first ball back into the bucket. Now reach in ( again no peeking ), and pick your second ball. ( Click the red Pick-A-Ball icon to simulate reaching into the bucket and select your next ball.)

b) What is the probability of selecting the color of the ball you selected. ( Enter the answer in decimal format to 4 decimal places ).

Answer:

a) the probability of selecting the color of ball ( RED ) that you just selected is 0.5000

b) the probability of selecting the color of the ball ( BLUE ) I selected is 0.3333

Step-by-step explanation:

Given that;

We have a total of 10 colored balls  in a small bucket.

Number of Red balls = 5

Number of White balls = 2

Number of blue balls = 3.

Now, assuming I clicked on the red Pick-A-Ball icon to simulate reaching into the bucket and picking a ball.

Also, Assuming that the color of ball that appeared is Red.

Then the probability of selecting the color of ball ( RED ) that I just selected will be;

P( selected Color ) = Number of Red balls / Total number of balls in the bucket

P( selected Color )  = 5 / 10 = 0.5000

Therefore, the probability of selecting the color of ball ( RED ) that I selected is 0.5000

b)

It is said that the game is Pick-A-Ball without replacement.

So assuming I went on and clicked on the red Pick-A-Ball icon to simulate picking a second ball.

Also, Assuming that the color of ball that appeared was blue.

Then the probability of selecting the color of ball ( BLUE ) that I just selected will be;

P( selected Color ) = Number of Blue balls / Total number of balls in the bucket

Now, since I picked the first ball without replacement, i.e I did not return it back to the bucket, The total number of balls left in the bucket now is 9.

so; P( selected Color ) = 3 / 9 = 0.3333

Therefore, the probability of selecting the color of the ball ( BLUE ) I selected is 0.3333

Answer:

[tex](d)\ L(S(x)) = 0.7225x[/tex]

Step-by-step explanation:

Given

[tex]S(x) = 0.85x[/tex] ----- Sales price

[tex]L(S) = 0.85S[/tex] ---- Loyalty member discount

Required

This is represented as: L(S(x))

So, we have:

[tex]L(S) = 0.85S[/tex]

Substitute S for S(x)

[tex]L(S(x)) = 0.85S(x)[/tex]

Substitute [tex]S(x) = 0.85x[/tex]

[tex]L(S(x)) = 0.85*0.85x[/tex]

[tex]L(S(x)) = 0.7225x[/tex]

According to the question,

By substituting the "S" for "S(x)", we get

→ [tex]L(S(x)) = 0.85 S(x)[/tex]

By substituting the value of "S(x)", we get

→ [tex]L(S(x)) = 0.85\times 0.85 x[/tex]

→               [tex]= 0.7225 x[/tex]

Thus the above answer is right.

Answer:

-3/5

Step-by-step explanation:

Given :-

And we need to find the value of sine for this angle. Therefore we can say that , Base = 16 units and Perpendicular = 12 units . So Using Pyhthagoras Theorem , we can find hypontenuse.

Using Pythagoras Theorem :-

[tex]:\implies[/tex] h² = p² + b²

[tex]:\implies[/tex] h² = 16² + 12²

[tex]:\implies[/tex] h² = 256 + 144

[tex]:\implies[/tex] h² = 400

[tex]:\implies[/tex] h = 20 u

Therefore the sine will be :-

[tex]:\implies[/tex] sinθ = p/h

[tex]:\implies[/tex] sinθ = 12/20

[tex]:\implies[/tex] sinθ = 3/5

[tex]:\implies[/tex] sinθ = -3/5

Therefore the value of sine is -3/5.

Answer:

18

Step-by-step explanation:

You have to divide both sides by 12 inorder to remain with the f on the other side since you want to find the value of f.

12f/12=216/12

F=18

Answer:

[tex]a =7[/tex]   [tex]b = 2[/tex]  [tex]c = -4[/tex]

Step-by-step explanation:

Given

[tex]\frac{3x}{x + 2} + \frac{4x}{x - 2} = \frac{ax^2 + bx}{x^2 + c}[/tex]

Required

Find a, b and c

[tex]\frac{3x}{x + 2} + \frac{4x}{x - 2} = \frac{ax^2 + bx}{x^2 + c}[/tex]

Take LCM

[tex]\frac{3x(x -2) + 4x(x+2)}{(x + 2)(x - 2)} = \frac{ax^2 + bx}{x^2 + c}[/tex]

Expand

[tex]\frac{3x^2 -6x + 4x^2+8x}{x^2 - 4} = \frac{ax^2 + bx}{x^2 + c}[/tex]

Collect like terms

[tex]\frac{3x^2 + 4x^2-6x+8x}{x^2 - 4} = \frac{ax^2 + bx}{x^2 + c}[/tex]

[tex]\frac{7x^2+2x}{x^2 - 4} = \frac{ax^2 + bx}{x^2 + c}[/tex]

By direct comparison:

[tex]ax^2= 7x^2 \to a = 7[/tex]

[tex]bx = 2x \to b = 2[/tex]

[tex]-4 = c \to c = -4[/tex]

Answer:

Best shot would be with vertical angles.

It wouldn't be adjacent angles because the two angles don't have an overlapping side.

It also can't be complementary/supplementary angles because they don't add up to 90* or 180* degrees.

However, Angle CDL creates vertical angles with Angle FDE with Angles FDC and EDL.
