A bag contains 7 red, 3 yellow, and 4 blue marbles. What is the probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first?


A) 11/14

B) 1/7

C) 2/13

D) 75/91

Answer:

X=12

Step-by-step explanation:

First, take the term out parenthesis being careful to manage the sign of individual term carefully :

x+42+3x=90

Next , subtract 42 from each side of the equation to isolate the x term while keeping equation balance :

x+42-42+3x=90-42

x+0+3x=48

x+3x=48

(1+3)x=48

4x=48

Now, Divide both side of equations by 4 to slove of x while keeping equation balance :

4x/4=48/4

x=12

Here,

(12+42)+3*12=90

54+36

90

Answer:

141°

Step-by-step explanation:

An octagon has 8 sides and 8angles so the sum of its interior angles is: (8-2)×180= 1080°

5x+133+16+126+162-12+30=1080°

5x=625

x=125°

x+16=141°

Answer:

I believe it would be Option A) 38

Answer:

Random, because he surveyed 30 random shoppers

==========================================================

Reason:

For choice A, the LCD is 30 since

We get 30 from the fact that 5*6 = 30. Notice 2/3 and 1/6 already have the LCD of 6. We could rewrite the 2/3 into 4/6 to help show this better. Effectively we want to find the LCD of 4/6, 1/6, 1/5

Cross choice A off the list because we want an LCD of 45 instead of 30.

--------------------

Choice B is the answer because

What we can do is find the LCD of 2/3 and 1/9 to get 9. The 2/3 turns into 6/9. This means we need to find the LCD of 6/9, 1/9, and 1/15

Multiply the two unique denominators to get 9*15 = 135, then divide by the GCF 3 to get 135/3 = 45.

Recall that LCD(x,y) = (x*y)/GCF(x,y)

--------------------

We can stop here since we know choice B is the answer.

But if you wanted to continue, then the LCD of 2/3, 1/5 and 1/3 is 3*5 = 15. This rules out choice C.

Choice D can be ruled out because the LCD is 27*7 = 189.

Step-by-step explanation:

k/4+3=14

Move 3 over

k/4=11

Divide both sides by 4

k=11/4

k=2.75 or 2 3/4

Answer:

80 degrees and 20 degrees.

Step-by-step explanation:

Isosceles means two angles are the same. If one angle is 80 degrees that means another angle is 80 degrees. The sum of all angles is 180 degrees. 80 degrees + 80 degrees = 160 degrees. After you do that you subtract 160 from 180 to get 20 degrees.

Answer:

306 m

Step-by-step explanation:

distance between her house and the third point:

280 - 10 = 270 m

distance between the third point  and the beach:

164 - 20 = 144 m

We have a right triangle ,then we can apply the Pythagorean theorem:

[tex]\text{the distance between her house and the beach} =\sqrt{\left( 270\right)^{2} +\left( 144\right)^{2} } = 306\ m[/tex]

Answer:

Yes it is possible

Step-by-step explanation:

Now, put it all together (9). Sin (A + B) is the two parts of the opposite - all divided by the hypotenuse (9). Putting that into its trig form: A very similar construction finds the formula for the cosine of an angle made with two angles added together.

Step-by-step explanation:

the slope is always the ratio "y coordinate change / x coordinate change" when going from one point of the line to another.

so, when going from (-2, 3) to (-3, 1)

x changes by -1 (from -2 to -3).

y changes by -2 (from 3 to 1).

therefore, the slope is

-2/-1 = 2/1 = 2

Answer:

21

Step-by-step explanation:

The first thing we do is multiply -3 by -9 to get 27. (Two negatives multiplied cancels each other out). Now we solve for -1+27-5. The resulting answer is 21.

7874

7874 rounded to 1 sf

if the previous digit is 5 or more round up, if not keep it as it is.

1 sf= 8000

therefore, 7874 rounded to 1 sf is 8000.

Answer:

8000

Step-by-step explanation:

Since the leftmost 7 is in the thousands place, you need to round the number to the nearest thousand. The digit to the right of the first 7 is an 8, so 7 goes up 1 to 8.

Answer: 8000

Answer:

4.5 > x

Step-by-step explanation:

Answer:

X=Y since x and y are alternating angles

Answer:

In other words, the solution is the point where the two lines intersect. To verify whether a point is a solution to a system or not, we will either determine whether it is the point of intersection of two lines on a graph or we will determine whether or not the point lies on both lines algebraically
