David is making patterns using these rules. Rule for Pattern A: start with 20 and subtract 2 Rule for Pattern B: start with 10 and subtract 1 Which patterns did David make?

Answers

Answer 1

Answer:

20,18,16,14,12,10,8,6,4,2

10,9,8,7,6,5,4,3,2,1

Step-by-step explanation:

Pattern A:

Rule : start with 20 and subtract 2

Pattern B:

Rule : Start with 10 and subtract 1

Pattern 1:

20 - 2 = 18

18 - 2 = 16

16 - 2 = 14

14 - 2 = 12

12 - 2 = 10

10 - 2 = 8

8 - 2 = 6

6 - 2 = 4

4 - 2 = 2

20,18,16,14,12,10,8,6,4,2

Pattern 2:

10 - 1 = 9

9 - 1 = 8

8 - 1 = 7

7 - 1 = 6

6 - 1 = 5

5 - 1 = 4

4 - 1 = 3

3 - 1 = 2

2 - 1 = 1

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°

The probability of event A occurring is 0.65. The probability of events A and B occurring together is 0.33. Events A and B are independent. What is the probability of event B?

Enter a number to the nearest hundredth.

Answers

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

Four of you enter in the race. You are told that only one will complete the course. What is the probability if you complete the Course. What is probability that you will not complete the course.

Answers

Answer:

25% probability that you complete the course

75% probability that you do not complete the course

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...

3/4 = 0.75 or 75%

A piece of machinery depreciates $6000 the first year,
$5700 the second year, and $5400 the third year. If the
rate of depreciation is constant, what is the amount of
depreciation of the piece of machinery in the sixth year?

Answers

Answer:

$4500

Step-by-step explanation:

it decreases $300 per yeae

Based on the rate of depreciation each year, the amount of depreciation of the machinery in the sixth year will be $300.

What is the annual depreciation amount?

The depreciation in the second year is:

= 6,000 - 5,700

= $300

The depreciation in the third year is:

= 5,700 - 5,400

= $300

If this amount remains constant till the sixth year therefore, then it means that the sixth year depreciation amount is also $300.

For the 2012-2013 National Hockey League and National Basketball Association seasons,
two hockey tickets and one basketball ticket purchased at their average rates cost $173.01.
One hockey ticket and two basketball tickets cost $162.99, when purchased at their
average rates. What were the average ticket prices for the two sports?

The average cost for an National Hockey League ticket was $____

The average cost for an National Basketball Association ticket was $____

Answers

9514 1404 393

Answer:

Hockey: $61.01Basketball: $50.99

Step-by-step explanation:

Using h and b to represent the prices of hockey and basketball tickets, respectively, the two purchases are ...

  2h +b = 173.01

  h +2b = 162.99

Subtracting the second equation from twice the first gives ...

  2(2h +b) -(h +2b) = 2(173.01) -(162.99)

  3h = 183.03

  h = 61.01

Substituting that into the first equation, we can solve for b:

  b = 173.01 -2h = 173.01 -2(61.01)

  b = 50.99

The average cost of an NHL ticket was $61.01.

The average cost of an NBA ticket was $50.99.

Which similarity statement is true?

ASRQ - ATRS
ASRQ - ARTQ
ASRQ - ARTS
ASRQ-AQRT

Answers

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.

What is congruent?

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.

A salesperson works 40 hours per week at a job where he has two options for being paid. Option A is
an hourly wage of $22. Option B is a commission rate of 4% on weekly sales. How much does he
need to sell this week to earn the same amount with the two options?


thank you so much!

Answers

His salary for 40 hours per week with an hourly rate is hours x the rate:

40 hours x $22 per hour = $880 per week.

If he is paid commission, to make the same , he needs to make $880 iin commissions.

The commission rate is 4%, to find how much sales is needed divide the amount he needs to make ( $880) by the rate:

880/ 4% = 880/ 0.04 = $22,000

He needs to sell $22,000

A biology test is worth 100 points and has 36 questions.

a. Multiple-choice questions are worth 2 points each and essay questions are worth 6 points each. How many questions of each type are on the test?

b. Your friend says that it is possible for the multiple-choice questions to be worth 4 points each. Is your friend correct? Explain.

Answers

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.

Weight of one toy = 1800 ÷ 6 = 300 grams

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

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
