65 degrees. alternate exterior angles of two parallel lines intersected by a transversal are equal

Answer:

60 or 65 degrees.

Step-by-step explanation:

Answer:

Approximately 0.51

Step-by-step explanation:

If events A and B are independent, then P(A and B) = P(A)*P(B) is a true equation.

We're given the following

     P(A) = 0.65

     P(A and B) = 0.33

So,

P(A and B) = P(A)*P(B)

0.33 = 0.65*P(B)

P(B) = 0.33/0.65

P(B) = 0.5076923076923

which is approximate. When we round to 2 decimal places, we get 0.51

Step-by-step explanation:

5x + 13 = 1/3(9x – 6) + 7x

5x + 13 = 3x-2+7x

5x-3x= -2-13

2x= -15

x= -7.5

Answer:

(a) 7 essays and 29 multiple questions

(b) Your friend is incorrect

Step-by-step explanation:

Represent multiple choice with M and essay with E.

So:

[tex]M + E= 36[/tex] --- Number of questions

[tex]2M + 6E = 100[/tex] --- Points

Solving (a): Number of question of each type.

Make E the subject of formula in [tex]M + E= 36[/tex]

[tex]E = 36 - M[/tex]

Substitute 36 - M for E in [tex]2M + 6E = 100[/tex]

[tex]2M + 6(36 - M) = 100[/tex]

[tex]2M + 216 - 6M = 100[/tex]

Collect Like Terms

[tex]2M - 6M = 100 - 216[/tex]

[tex]-4M = - 116[/tex]

Divide both sides by -4

[tex]M = \frac{-116}{-4}[/tex]

[tex]M = 29[/tex]

Substitute 29 for M in [tex]E = 36 - M[/tex]

[tex]E = 36 - 29[/tex]

[tex]E = 7[/tex]

Solving (b): Can the multiple questions worth 4 points each?

It is not possible.

See explanation.

If multiple question worth 4 points each, then

[tex]2M + 6E = 100[/tex] would be:

[tex]4M + xE = 100[/tex]

Where x represents the number of points for essay questions.

Substitute 7 for E and 29 for M.

[tex]4 * 29 + x * 7 = 100[/tex]

[tex]116 + 7x = 100[/tex]

Subtract 116 from both sides

[tex]116-116 + 7x = 100 -116[/tex]

[tex]7x = 100-116[/tex]

[tex]7x = -16[/tex]

Make x the subject

[tex]x = -\frac{16}{7}[/tex]

Since the essay question can not have worth negative points.

Then, it is impossible to have the multiple questions worth 4 points

Your friend is incorrect.

The test contained 29 multiple choice questions and 7 essay questions.

Let x represent the number of multiple questions and y represent the number of essay questions.

Given that there are a total of 36 questions, hence:

x + y = 36    (1)

Also, the test is worth a total of 100 points, hence:

2x + 6y = 100   (2)

Solving equation 1 and 2 simultaneously gives:

x = 29, y = 7

Therefore the test contained 29 multiple choice questions and 7 essay questions.

Answer:

x = 30°

Step-by-step explanation:

As we can see it is right angled triangle so

2x + x + 90° = 180° (Sum of angels of triangle )

3x + 90° = 180°

3x = 180° - 90°

3x = 90°

x = 90° / 3

x = 30°

Answer:

12.5 miles per hour

Step-by-step explanation:

Math

Answer:

12.5 MPH

Step-by-step explanation:

Miles per hour can also be written as miles/hour

therefore 3.75 miles in .3 hours can also be written as 3.75 miles/.3 hours

3.75 / .3 = 12.5

Therefore the cyclist was going 12.5 miles per hour

Answer: c

Step-by-step explanation:

look at the equation and insert the value of X from the table into the equation and figure out which one will give you the same sum for the values. for example f(x) = 3(-2)-1

this answer gives you f(x)= -6 -1 which will give u a sum of -7

another one : f(x)= 3(0)-1

3 multiplied by 0 gives you 0 therefore you are left with -1

by doing this you prove that this equation works with ur x values and gives you the same sum you have for f(x)

Answer:

It would be B (The 2nd option)

Step-by-step explanation:

The two triangles that can be considered similar are RTQ and SRQ. These two have one right angle and share angle Q, make them similar by AAA.

Both the 2nd option and the 4th option mention these triangles, but the triangles are not named correctly in the 4th option.

The similarity statement that is true is

ΔSRQ - ΔRTQ

The correct option is B.

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

The two triangles that are similar are RTQ and SRQ. According to the AAA (Angle-Angle-Angle) similarity criterion, since they share two congruent angles, ∠RTS and ∠STQ, they must be similar. Therefore, we can write:

ΔRTQ ~ ΔSRQ

This similarity statement means that triangle RTQ is similar to triangle SRQ. So, we can use the corresponding parts of similar triangles to write:

SR / RT = SQ / TQ = RQ / RQ

where SR, RT, SQ, TQ, and RQ are the corresponding side lengths of the two triangles.

Since RQ / RQ = 1, we can simplify the above equation to:

SR / RT = SQ / TQ

This means that the ratios of the corresponding side lengths of the two triangles are equal. We can use this to find the true similarity statement:

ΔSRQ ~ ΔRTQ

So, the correct similarity statement is:

ΔSRQ - ΔRTQ.

Answer:

Step-by-step explanation:

1.8kg into grams

1.8kg = 1800 grams

Total toys = 6

Weight of one toy = 1800 ÷ 6 = 300 grams

Weight of 4 toys = 300 x 4 = 1200 grams = 1.2kg

Answer:

Step-by-step explanation:

a) 1 Kg =  1000 grams

1.8 Kg = 1.8 * 1000 = 1800.0 = 1800 grams

b) Weight of one toy = Weight of all the 6 toys ÷ 6

                                 = 1800 ÷ 6

                                = 300 grams

c)  Weight of 4 toys = 4 * 300

                               = 1200 grams

                              = 1200 ÷ 1000

                              = 1.2 Kg

Step-by-step explanation:

If there are a total of 4 individuals entering the race and only one is able to complete the course then the probability that you will complete the course would be

1/4 = 0.25 or 25%

This is because you only represent 1 out of the 4 total participants. The opposite would be the case to calculate the probability that you will not complete the course since there are three other candidates with that could have completed it, therefore...
