can someone please help me with numbers 11 12 13 and 14 please , and can you please explain how you got the answer?
Answers
Answer:
11) x = 4
12) x = 12
13) A = 45
14) A = 40
Step-by-step explanation:
All triangle angles must add up to 180 degrees. If they do not, the triangle is not considered a triangle.
So for triangle 11, solve using the equation: (16x + 4) + 47 + 65 = 180. First add 47 + 65 together to get 112. Subtract 112 from both sides to get (16x + 4) = 68. Subtract 4 from both sides to get 16x = 64. Divide 16 from both sides to get x = 4. Use the same technique for the other triangle.
For triangle 12, solve using the equation: (3x + 9) + 60 + 75 = 180. Add 60 + 75 to get 135. Subtract 135 from both sides to get (3x + 9) = 45. Subtract 9 from both sides to get 3x = 36. Divide 3 from both sides to get x = 12.
For triangle 13, solve using the equation: (62 + x) + (x + 51) + 79 = 180. For this equation, add the common variable first to get 113 + 2x + 79 = 180. You can still further simplify by adding 113 + 79 to get 192. The new equation is 192 + 2x = 180. Subtract 192 from both sides to get 2x = -12. Divide 2 from both sides to get x = -6. Now, to solve for angle A, insert the x value, -6, into Angle A's expression: x + 51. The x value would change the expression into -6 + 51. Solve to get 45. Use this technique for the other triangle as well.
For triangle 14, solve using the equation: 6x + 4x + 80 = 180. First add common variables to get 10x + 80 = 180. Subtract 80 from both sides to get 10x = 100. Divide both sides by 10 to get x = 10. To solve for Angle A, insert the x value, 10, in place of x. This turns the expression 4x into 4(10). Solve to get 40.
Hope it helps!

Part B: Suppose Steven combined the table-
tennis balls into one large bag instead of two
individual bags. Would the probability change
from Part A if Steven wanted to draw a "1" and a
"B" without replacement?
A
Answers
Answer:
D.
Yes, the probability would change because you are drawing from one bag and this changes the number of possible outcomes.
Step-by-step explanation:
Yes, the probability would change because you are drawing from one bag and this changes the number of possible outcomes.
What is the probability?Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?
Given:
Suppose Steven combined the table tennis balls into one large bag instead of two individual bags.
When the two bags are combined into one, the number of possible outcomes is reduced.
Drawing from one bag means that there is now only one set of balls to choose from, rather than two separate sets.
This means that the total number of possible outcomes is reduced, which changes the probability of drawing a "1" and a "B" without replacement.
Therefore, the probability would change.

what is the value of X. 2.5(x+4)= 4.75
Answers
Answer:

Step-by-step explanation:
2.5(x+4)=4.75
or,2.5x+10=4.75
or,2.5x=4.75-10
or,2.5x= -5.25
or,x =-5.25/2.5
or,x= -2.1
∴x=-2.1
(Ans)
Hope you find it helpful.........
Answer:
2.5(x+4)=4.75
2.5x+10=4.75
2.5x=4.75-10
2.5x=-5.25
Divide through by 2.5
2.5x÷2.5=-5.25÷2.5

Answers
Answer:
4 red marbles and 6 blue marbles is the correct answwer
Step-by-step explanation:
Answer:
A.) 4 red marbles and 6 blue marbles
Step-by-step explanation:
If you times 2 x 2 then you will get 4
If you times 3 x 2 then you will get 6
And since the ratio is red : blue
2 : 3 is equivalent to 4 : 6
Just like [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.
if you were to do a fraction graph, 2 of the 3 [tex]\frac{1}{3}[/tex] bars would be the same length of 4 [tex]\frac{1}{6}[/tex] bars:

Answers
Answer:
c=1
Step-by-step explanation:
Simplifying
3 + 2c = 5
Solving
3 + 2c = 5
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2c = 5 + -3
Combine like terms: 3 + -3 = 0
0 + 2c = 5 + -3
2c = 5 + -3
Combine like terms: 5 + -3 = 2
2c = 2
Divide each side by '2'.
c = 1
Simplifying
c = 1
Answer:
= 4
Step-by-step explanation:
Subtract 15 from both sides of the equation
6+15=39
6+15−15=39 − 5

6=24
Divide both sides of the equation by the same term
(6=24)/6

Answers
Answer: The parking lot in the drawing is 36 centimeters.
Step-by-step explanation:
Given: Actual width of parking lot = 54 meters
The scale she used was 2 centimeters : 3 meters.
i.e. 3 actual meters = 2 centimeters on drawing
⇒ 1 actual meter = [tex]\dfrac23[/tex] centimeters on drawing
⇒ 54 actual meters = [tex]54\times\dfrac23[/tex] centimeters on drawing
⇒ 54 actual meters = 36 centimeters
Hence, the parking lot in the drawing is 36 centimeters.
