If a bag of balloons consists of 47 white balloons, 5 yellow balloons, and 10 black balloons, what is the approximate likelihood that a balloon chosen randomly from the bag will be black?

Answer:

Step-by-step explanation:

If Y and Z are points of tangency, then |XY| = |XZ|.

We have

[tex]|XY|=9a^2-30\\|XZ|=3a[/tex]

Domain

[tex]a>0[/tex]

Substitute

[tex]9a^2-30=3a\qquad|\text{subtract}\ 3a\ \text{from both sides}\\\\9a^2-3a-30=0\qquad|\text{divide both sides by 3}\\\\3a^2-a-10=0\\\\3a^2-6a+5a-10=0\\\\3a(a-2)+5(a-2)=0\\\\(a-2)(3a+5)=0\iff a-2=0\ \vee\ 3a+5=0\\\\a-2=0\qquad|\text{add 2 to both sides}\\a=2\\\\3a+5=0\qquad|\text{subtract 5 from both sides}\\3a=-5\qquad|\text{divide both sides by 3}\\a=-\dfrac{5}{3}<0[/tex]

Answer:

17.25 ; 1:01:13 ; 4 hours 47 minutes, 38 seconds

Step-by-step explanation:

From the picture attached :

The shortest distance cycled :

17.25 < 25.80 < 27.42

Hence, shortest distance cycled is : 17.25

Shortest cycling time :

1:01:13 < 1:50:05 < 1:56:20

Hence, shortest distance cycled is : 1:01:13

Total cycling time:

1:01:13 + 1:50:05 + 1:56:20

1 + 1 + 1 = 3 hrs

01 + 50 + 56 = 107 = 107/60 = 1 hr 47 minutes

13 + 05 + 20 = 38 seconds

Total cycling time :

(3 + 1 hr 47 minutes + 38 seconds) = 4 hours 47 minutes, 38 seconds

Answer:

1/2

Step-by-step explanation:

find the slope (1,1) and (2,3) do change in y over change in x then simplify

Answer:

2

Step-by-step explanation:

Find 2 easy-to-read points. Points that easy to read are on the intersection of grid lines.

For example, choose (1, 1) and (2, 3).

slope = rise/run

rise = difference in y

run = difference in x

Start at point (1, 1). To go to point (2, 3), first you go up 2 units. The difference in y is 2, so the rise is 2. Then you go 1 unit to the right. The difference in x is 1, so the run is 1.

slope = rise/run = 2/1 = 2

Answer: slope = 2

Answer:

Step-by-step explanation:

The lines are parallel to one another.

A linear system of equations has no solution if the graphs are parallel and the two lines never meet.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

There can be one solution to a system of two linear equations, an infinite number of solutions, or no solutions at all. The number of solutions to a system of equations can be used to categorize it.

A system is deemed consistent if there is at least one solution to the problem. A consistent system is said to be independent if it only has one possible outcome.

Thus, a linear system of equations has no solution if the graphs are parallel and the two lines never meet.

Answer:

-12.5%

-14.29%

Step-by-step explanation:

For #2:

Original price is $2.00, that price decreased by $0.25 is $1.75. First figure out what $0.25 out of $2.00 is as a percent:

0.25/2.00 = 0.125 = 12.5%

Then, since the price DECREASED by $0.25, the percent would be negative.

For #4:

Original price is $3.50, that price decreased by $0.50 is $3.00. Like #2, you need to figure out what $0.50 out of $3.50 is as a percent:

0.50/3.50 = 0.1429 = 14.29%

Then, since the price DECREASED by $0.50, the percent would be negative.

Step-by-step explanation:

Answer:

x = 17.5

Step-by-step explanation:

[tex] \frac{16}{10} = \frac{28}{x} [/tex] (angle bisector theorem)

Cross multiply

16 × x = 28 × 10
