∠A and ∠B are vertical angles. If m ∠A=(4x+6)° and m ∠B=(2x+18)°, then find the value of x.

Answers

Answer 1

Answer:

x = 6

Step-by-step explanation:

You want the value of x if the expressions (4x+6)° and (2x+18)° represent the measures of vertical angles.

Vertical angles

Vertical angles have the same measure, so these expressions are equal to each other:

4x +6 = 2x +18

2x = 12 . . . . . . . . . . subtract 2x+6 from both sides

x = 6 . . . . . . . . divide by 2

Additional comment

The angles are each 30°.

Mrs. Tinney’s class has the following scores on their most recent test:

80

1. Calculate the five-number summary and use it to draw (and label) your box and whisker plot on a number line. Show your work for all calculations.

2. If Mrs. Aguiar’s class has a five-number summary of 50, 60, 70, 80, and 95, which class’ scores are more consistent? How do you know?

3. The mean for Mrs. Tinney’s class is 85 and the mean for Mrs. Aguiar’s class is 70. What conjecture could we make about symmetry? Explain.

Answers

Answer:

1. Five-number summary for Mrs. Tinney's class scores:Minimum (Min): 60

First Quartile (Q1): 72

Median (Q2 or Median): 80

Third Quartile (Q3): 88

Maximum (Max): 100To draw the box and whisker plot, we can plot these

values on a number line:

| | | | |

60 72 80 88 95 100

We can then draw a box from Q1 to Q3, with a line inside representing the median (Q2), and draw whiskers from the box to Min and Max.

2. Mrs. Aguiar's class scores are more consistent compared to Mrs. Tinney's class scores. This can be determined from the interquartile range (IQR), which is the difference between the third quartile (Q3) and the first quartile (Q1) in a box and whisker plot. A smaller IQR indicates less variability in the data and hence more consistency. In this case, Mrs. Aguiar's class has an IQR of 80 - 60 = 20, while Mrs. Tinney's class has an IQR of 88 - 72 = 16. Therefore, Mrs. Aguiar's class scores are more consistent.

3. Based on the mean values, we can make a conjecture about symmetry. The mean is a measure of central tendency that represents the average of a set of data points. If the mean is close to the median, it suggests that the data is approximately symmetric. In this case, the mean for Mrs. Tinney's class is 85, which is closer to the median (Q2) of 80, indicating approximate symmetry. On the other hand, the mean for Mrs. Aguiar's class is 70, which is not close to the median of 80, suggesting that the data may not be symmetric. However, further analysis using other measures of skewness or visualization techniques may be needed for a more conclusive assessment of symmetry.

Answer:

Step-by-step explanation:

The angles GCJ and ACB are congruent.

So GCJ=ACB=63°.

And in Triangle ABC the sum of all angles is 180°.

Such an angle of BAC is calculated by:

The sum of all angles = ABC + BCA + CAB

180 = 90 + 63 + CAB

CAB = 27°

Then again angle KAI and CAB are congruent then

KAI = 27°

Please help asap! Finding the Volume of a Cylinder... Tysm!♡♡

Answers

Answer:

i belive its 22

Step-by-step explanation:

V = 22

To find the volume of 11 x 2, you need to know the third dimension, as volume is a three-dimensional measure. Assuming you mean the dimensions of a rectangular solid, you would need to know the height or depth of the object to calculate the volume. As for screen time for children, the American Academy of Pediatrics recommends limiting it to one hour per day for children aged 2-5 and to no more than two hours per day for children aged 6 and older. Engaging in creative play can help children develop important skills, such as problem-solving and communication, while excessive screen time has been linked to negative effects on cognitive and social development.

and 11 x 2 = 22.

Answer:

The answer is 22

Step-by-step explanation:

You have to multiply the base times the height (2 x 11) Doing that will get you 22 ft.

Answer:

In the given equations, "m" represents the slope of the line and "b" represents the y-intercept.

Part A includes four different equations, and they all have different values for "m" and "b". However, since there is no information about any changes in the equations or the values of "m" and "b", it is not clear which equation is being referred to in Part B.

Therefore, without additional context, it is impossible to determine whether "m" or "b" will change in the equation.

Darla’s dinner at a restaurant cost $23.18 before tip. She wants to leave a 20% tip. What is the total cost of the dinner after Darla adds the tip?

Answers

Answer:

$27.816

Step-by-step explanation:

First we have to find out what 20% of 23.18 is. Let x represent the amount of the tip.

(cross multiply)

20 = x

100 23.18

20 x 23.18 = 463.6

463.6 ÷ 100 = 4.636

x = $4.636

Now we add the amount of the tip to the original price of the dinner.

23.18 + 4.636 = 27.816

Therefore the total cost of the dinner including the tip is $27.816

The correct answer is 23.18%

A fence post that is 5 feet tall casts a 2-foot shadow at the same time that a tree that is 27 feet tall casts a shadow in the same direction. Determine the length of the tree's shadow.

8.5 feet
10.8 feet
12 feet
21.4 feet

Answers

Answer:

Let s be the height of the tree's shadow.

We set up and solve this proportion:

5/2 = 27/s

5s = 54

s = 10.8 feet

The length of the tree's shadow is 10.8 feet.

I believe the answer is 10.8 feet

Which value from the set { -6, -4, -1, 0, 2, 4} satisfy the inequality?

−1/2x + 4 ≥ 6

Answers

Answer:

-4

Step-by-step explanation:

To find the value from the given set that satisfies the inequality, we can substitute each value into the inequality and see which one makes it true.

−1/2x + 4 ≥ 6

Subtracting 4 from both sides:

−1/2x ≥ 2

Multiplying both sides by -2 (and reversing the inequality):

x ≤ -4

Now we can check each value from the set and see which one satisfies the inequality:

-6 ≤ -4 (not true)

-4 ≤ -4 (true)

-1/2 ≤ -4 (not true)

0 ≤ -4 (not true)

2 ≤ -4 (not true)

4 ≤ -4 (not true)

Therefore, the only value that satisfies the inequality is -4.

Convert to military time:
9:15 A.M.

Answers

Answer:

To convert 9:15 A.M. to military time, we can follow these steps:

1. Determine if the given time is in the morning or afternoon. In this case, "A.M." indicates that it is in the morning.

2. Identify if the given hour is between 1 and 11. In this case, the hour is 9, which falls within this range.

3. For morning hours, we keep the hour as it is. So, the hour remains 9.

4. Write the minutes as they are. In this case, the minutes are 15.

Putting it all together, 9:15 A.M. in military time is simply 0915 hours.

$3.48 chocolate pretzels

$8.26 almonds

$4.98 trail mix

Answers

Answer: $41.81 in total

Step-by-step explanation:

3.48 x 2.5 = 8.7

8.26 x 2.5 = 20.65

4.98 x 2.5 = 12.45

8.7 + 20.65 + 12.45 = $41.8

The cost of chocolate pretzels for 2.5 pounds is $8.7.

The cost of almonds for 2.5 pounds is $20.65

The cost of trail mix for 2.5 pounds is $12.45.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

$3.48 chocolate pretzels

$8.26 almonds

$4.98 trail mix

So, the cost of chocolate pretzels for 2.5 pounds

= 3.48 x 2.5

= $8.7

and, the cost of almonds for 2.5 pounds

= 8.26 x 2.5

= $20.65

and, the cost of trail mix for 2.5 pounds

= 4.98 x 2.5

= $ 12.45
