Answer 1

Answer: We can use equations to represent the measures of the angles described above. One equation might tell us the sum of the angles of the triangle. For example,

X°+145°=180° because there supplementary angles.

X°=35° because 180-145=35°.

You can purchase 2 sodas for 3 dollars, how much does 6 sodas cost?

Answers

Answer:

It costs $9

Step-by-step explanation:

Lets look at the ratio:

2/3

We need x:

6/x

Make an equation using the butterfly method:

3(6) = 2x

Simplify:

18=2x

Divide both sides by 2:

x=9

It costs $9

if you purchase 2 sodas it’s $3, 4 sodas it’s $6, and 6 sodas it’s $9. so it would be $9

An urn contains b black balls and r red balls. One of the balls is drawn at random, but when it is put back in the urn c additional balls of the same color are put in with it. Now suppose that we draw another ball.

Required:
Show that the probability that the first ball drawn was black given that the second ball drawn was red is b/(b r c).

Answers

Answer:

Please see the explanation below for proof

Step-by-step explanation:

Probability of choosing black ball from the bag

[tex]\frac{b}{b+r}[/tex]

Probability of choosing red ball from the bag

[tex]\frac{r}{b+r}[/tex]

After the addition of c balls of correspondent color –

P (R2/B1) [tex]= \frac{r}{(r+b+c)}[/tex]

P (R2/B2) [tex]=\frac{r+c}{(r+b+c)}[/tex]

B1 and B2 are mutually exclusive event

P (B1/R2) = [tex]\frac{\frac{r}{(r+b+c)} *\frac{b}{b+r}}{\frac{r}{(r+b+c)}*\frac{b}{b+r} + \frac{r+c}{(r+b+c)}* \frac{b}{b+r}}[/tex]

P (B1/R2) [tex]=\frac{b}{(r+b+c)}[/tex]

Find an equivalent fraction to 5/6 only.

Answers:
A) 2/4
B) 10/12
C) 11/6
D) 20/24
E) 50/60

Answers

B), D), and E) are all equivalent fractions to 5/6.
2/4 isn’t because simplified it equals 1/2
11/6 isn’t because it cannot be simplified further
10/2 = 5 and 12/2 = 6, which is why B) is one of the answers
20/4 = 5 and 24/4 = 6, which is why D) is another answer
50/10 = 5 and 60/10 = 6, which is why E) is the third answer

Answer:

B D and E

Step-by-step explanation:

Remark

It's hard to know how to tackle this. I suppose the easiest way is to divide the numerator and denominator by a common factor.

2/4

The common factor is 2

Divide the 2 by 2 and the 4 by 2

2/2 = 1

4/2 = 2

The fraction reduces down the 1/2 which is not 5/6

10 / 12

The common factor is 2.

10/2 = 5

12/2 = 6

Looks like this is your answer. But is it the only one.

11/6

These two have no common factor. The answer is 11/6 which is not 5/6

20 / 24

The common factor of these two is 4

20/4 = 5

24/ 4 = 6

This is also = to 5/6

50 / 60

The common factor is 10

50/10 = 5

60/10 = 6

That's equal to 5/6 as well.
