The value of x in the given triangle is  [tex]1\frac{3}{5}[/tex]

What are the similar triangles?

Similar triangles have the same corresponding angle measures and proportional side lengths.

Given that, two triangles are similar, Δ MNO ~ Δ PQR,

According to definition of similar triangles,

PR/MO = QP/NM

x/4 = 2/5

x = 8/5

x = [tex]1\frac{3}{5}[/tex]

Hence, the value of x in the given triangle is  [tex]1\frac{3}{5}[/tex]

Part D
Finally, use decimal numbers to write an expression that represents the net change in Rylee’s bank account balance for her entire shopping trip. Use your answers from parts A through C to guide you.


PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).

Further simplify the expression by factoring -$23.50 from both terms:

-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).

Answers

Answer:

look at explanation

Step-by-step explanation:

PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:

-$23.50.

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is

-$23.50 – (-$23.50 × 0.2).

Further simplify the expression by factoring -$23.50 from both terms:

-$23.50 – (-$23.50 × 0.2)

=

-$23.50(1 – 0.2)

=

-$23.50(0.8).

The net change to her banking account balance is $83.22.

What is net change?

The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.

Given that, She spent $36.50 plus 8% tax.  (to calculate the tax amount, we have to multiply the cost by the percentage in decimal form)

36.50 x (8/100) =$2.92 (value of tax)

Adding to the original cost

36.50+2.92 = $39.42

Then, she spent $25 to refuel her car at the gas station.

39.42 +25 = $64.42

She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase

23.50 x (20/100) = 4.7 (amount of discount)

Subtracting to the purchase

23.50 -4.7= $18.8

Hence, adding to the total cost.

64.42 +18.8 = $83.22

Part A

For his class survey, Walden chose the question, How many people live in your home, including yourself? He asked his friend Drake to help him with the survey. Walden asked 10 students in his class the question, and Drake posed the same question to 10 more students in their class.

Based on the responses, they wrote these data sets:

Walden’s data set: 2, 2, 2, 3, 3, 3, 3, 4, 4, 4

Drake’s data set: 3, 3, 4, 4, 4, 4, 5, 6, 7, 9

Answer:

The center of Walden’s data, 3, is less than the center of Drake’s data set, 6.

Step-by-step explanation:

i got this answer^

Answer:

Part A) Question 1 The center of Walden’s data, 3, is less than the center of Drake’s data set, 6.

Part A) Question 2 Walden’s data ranges from 2 to 4, and Drake’s data set ranges from 3 to 9. Drake’s data set has a greater spread than Walden’s data set.

Part A) Question 3 The graph of Walden’s data set will be symmetrical about the center, and the graph of Drake’s data set will be skewed to the right.

Part A) Question 4 Walden’s data set doesn’t have any outliers. Drake’s data has an outlier with the value 9, which is at the higher end of the distribution.

Part B) Question 1 The center is 5.

Part B) Question 2 This data set has no spread at all. All the values are the same, so the difference of the highest value and the lowest value in the set is 0.

Part B) Question 3 All the data points would lie at the same point, 5. The graph would be a single bar at the value 5, with no other data points anywhere else.

Part B) Question 4 No. All the observations in the data set are the same, and the only answer to the question is 5. So there is no need to find the center, spread, or shape of the data set.

Part B) Question 5 No, Walden was not asking a statistical question because all the people living in the same house would give him the same answer to his question. So the question did not allow for multiple answers among the population that it was posed to.

Diego’s history teacher writes a test for the class with 26 questions. The test is worth 123 points and has two types of questions: multiple choice worth 3 points each, and essays worth 8 points each.

How many essay questions are on the test? Explain your reasoning.

Answers

Answer: 9 essay questions

Step-by-step explanation:

The test has 26 questions

The test is worth 123 points

The test has two types of questions:

Multiple choice worth 3 points each

Essays worth 8 points each

Let the number of multiple choice questions be, m, and the number of essay questions be , e.

This forms a simultaneous equation below:

m + e = 26 ... (i)

3m + 8e = 123 ... (ii)

Multiplying (i) by 3 and (ii) by 1 we get:

3m + 3e = 78 ... (i)

3m + 8e = 123 ... (ii)

Subtracting (ii) - (i) we get;

0m + 5e = 45

5e = 45

e = 45 ÷ 5 = 9

So there are 9 essay questions.

and;

m + 9 = 26

m = 26 - 9 = 17

There are also 17 multiple choice questions.

So if there are 26 questions on the test and each test is worth 123 points and only two types of questions on the test multiple choice worth three points and essays worth eight points so if you wanna do it the easy way just get the essay points 8 and divid it by the amount of points on the test which is 123 And you want to divide that and you will have your answer if you do the math correctly you will have 15 remainder three so there will be only 15 essay questions and one multiple-choice so yeah that is my answer well we can agree and disagree depends on you

Marissa collects donations for a dance marathon. One group of sponsors will donate a total of $25 for each hour she dances. Another group of sponsors will make a one-time donation of $100 regardless of how long she dances. What number of hours should she dance if she wishes to raise at least $500?

Answers

Answer:

20 hours

Step-by-step explanation:

25x20=500

The one time donation will not fufill the needs, but the payment each hour will help Marissa reach her donation goal.

One group giving $100 regardless how long but one donating $25 per hour. So $100+25(hours)= 500 to find the solution since they need $500 deduct $100 then it’s 400 divided by 25 which is 16 hours so

$100+25(16)=500 hours. So 16 hours
