Can someone please explain to me how this works or something please? This is a very hard subject for me T-T

Answers

Answer 1

Answer:

29.2 ft

Step-by-step explanation:

a^2 is the base so it’s how long the shadow is.

b^2 is the leg so it’s the height of the tree

c^2 is the hypotenuse so it’s the top of the tree to end of the shadow (what your trying to find)

25^2 + 15^2 = c^2

625+ 225= c^2

850= c^2

(square root both sides)

29.2= c

Answer 2

Answer:

The solution is ([4], [19]).

Step-by-step explanation:

To solve the system of equations using the substitution method, we can follow these steps:Step 1: Start with the given equations:

y = 4x + 3 (Equation 1)

y = 7 + 3x (Equation 2)Step 2: Choose one of the equations and solve for one of the variables in terms of the other variable. Let's choose Equation 1 and solve for y in terms of x:

y = 4x + 3Step 3: Substitute the expression for y from Equation 1 into Equation 2 and solve for x:

4x + 3 = 7 + 3x (Substituting y = 4x + 3 from Equation 1)

4x - 3x = 7 - 3

x = 4Step 4: Substitute the value of x found in Step 3 back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:

y = 4(4) + 3 (Substituting x = 4)

y = 19So the solution to the system of equations is x = 4 and y = 19. Therefore, the solution is ([4], [19]).

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%

Luke walked 6 blocks from his house to the bus stop. He rode the bus 24 blocks to the post office. Later, he came home the same way. How many blocks did Luke travel in all?

Owen has 50% more cash than Sandra, and Sandra has 20% more cash than Amada. How much more cash than Amada does Owen have, if Amada has $4.35?

Answers

Answer: $3.48

Step-by-step explanation:

Amada has $4.35. Since Sandra has 20% more cash than her, Sandra has $5.22. Owen has 50% more cash than Sandra, so he has $7.83. The difference between $7.83 and $4.35 is $3.48.

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°

Which expression is equivalent to 1/4 (14x - 10) -3 (2 1/2x - 1 1/2) ?

A. 4x - 7
B. 4x + 2
C. -4x - 7
D. -4x + 2

Answers

To simplify the expression, we can start by distributing the coefficients:

1/4 (14x - 10) -3 (2 1/2x - 1 1/2) = 7/2x - 5/2 - 15/2x + 9/2

Next, we can combine like terms:

= (-15/2x + 7/2x) + (-5/2 + 9/2)

= -8/2x + 4/2

= -4x + 2

Therefore, the expression 1/4 (14x - 10) -3 (2 1/2x - 1 1/2) is equivalent to -4x + 2. Answer choice D is correct.

Answer:

the expression 1/4 (14x - 10) -3 (2 1/2x - 1 1/2) is equivalent to -8x + 2, which is option D.

$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

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.

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.
