Answer:

D

Step-by-step explanation:

Answer: D. 151 degrees.

Step-by-step explanation:

To solve this, first find the interior angle measures of the triangle. We know that it is a right triangle, so the right angle is 90 degrees, and the second angle is 61 degrees.

180 - 90 - 61 = 29 degrees.

Looking at the attached diagram - you can treat the angles surrounding s and 29 as a circle. There are 360 degrees in a circle, so the angle measures in the circle must add up to 360.

We also know that the angle directly opposite the triangle's 29 degree measure is also 29 degrees, so we can make an equation based on this information:

[tex]360 = 2(29) + 2(s)[/tex]

Solve for s:

[tex]360 = 2(29) + 2(s)\\360 = 58 + 2s\\302 = 2s\\s = 151[/tex]

S is equal to 151 degrees.

Answer:

6.5 cm

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh where b is the base and h is the height

26 = 1/2 (8) *h

26 = 4h

Divide each side by 4

26/4 = 4h/4

6.5 = h

Answer:

6.5 cm

Step-by-step explanation:

Area = ½ × base × height

26 = ½ × 8 × height

26 = 4height

height = 6.5 cm

Answer:

Probability of both digits being the same is a likely outcome (A) and;

The first digit is greater than the second digit is equally likely as the first digit less than the second digit (C)

Step-by-step explanation:

Question:

Ross forms all two-digit whole numbers using digits 1, 2, and 3. He allows digits to repeat. Select statement(s) that are CORRECT. *

a) probability of both digits being the same is a likely outcome

b) the probability that a number includes the digit 2 only once is 5/9

c) The first digit is greater than the second digit is equally likely as the first digit less than the second digit

d) 23 is an unlikely outcome

SOLUTION

Find attached how I got the value combination.

Forming a two-digit whole number with digit 1,2 and 3 where repetition is allowed:

11, 12, 13, 21, 22, 23, 31, 32, 33

Let's check which of the options are correct.

a) Is probability of both digits being the same is a likely outcome?

From the numbers we got: 11, 22 and 33 have both digits the same.

Yes, the probability is a likely outcome

Option A is correct

b) Let the probability that a number includes the digit 2 only once = Pr( 2 only once)

Pr( 2 only once) = (digits which have number 2 once / total number)

12, 21, 23, 32

Digits which have number 2 once = 4

Total = 9

Pr( 2 only once) = 4/9

4/9 is not same as 5/9

So option B is wrong

c)The first digit is greater than the second digit = 21, 31, 32 = 3 in total

the first digit less than the second digit = 12, 13, 23 = 3 in total

Yes, they are equal in number

Option C is correct

d) 23 is a likely outcome

Option D is wrong

Step-by-step explanation: just common sense

To identify the function represented by a graph, one must analyze the slope, intercepts, and shape of the graph. The graph of a constant function is a horizontal line, while the predator-prey cycle would show an oscillating pattern. The potential energy graph in physics can display a double well pattern, while signal transduction might show a cascade over time, and motion graphs represent various types of movement.

Identifying the function represented by a graph involves analyzing various elements such as the shape of the graph, its slope, and intercepts, as well as any restrictions on the domain. For instance, when you come across a graph of a function that appears as a straight line, it's crucial to look at the slope and y-intercept to determine the equation of the line. If the graph is a horizontal line, then the function represents a constant value indicating that no matter the change in the independent variable x, the dependent variable y remains the same.

For analyzing a predator-prey cycle, we need to recognize the typical oscillating pattern that represents populations of predators and preys over time. When interpreting graphs showing potential energy in physics, we are often looking at a function that might show the energy levels as a function of position, with critical points determined by solving relevant equations and considering derivatives to find minima and maxima.

In the context of a biological process such as signal transduction, creating a graph would involve plotting the stages of the signaling pathway over time, which would likely result in a plot showing the cascade of events leading from the signal to the final response. When considering the graphs of the position of a moving object over time, we might see different types of curves representing different types of motion, such as uniform motion depicted by a straight line or accelerated motion depicted by a parabolic curve.

Answer:

700 teens

Step-by-step explanation:

If five out of 7 teens do homework every night

There are 980 teens

How many out of 980 teens would do homework every night?

Firstly divide 980 teens by 7

Which is 980/7=140

Next is,

Out of 7 teens, there are 5 who do homework every night

So, multiply 140 by 5

140×5=700 teens

This means, the reasonable prediction of teens who do homework every night out of 980 is 700 teens

The predicted number of teens who would do homework every night out of 980 is approximately 700 based on the given information.

To predict the number of teens out of 980 who would do homework every night based on the given information that five out of seven teens do homework every night, we can follow these steps:
1. Calculate the proportion of teens who do homework every night:
- Proportion = 5 / 7
2. Determine the expected number of teens out of 980 who would do homework every night:
- Expected number = Proportion * 980
3. Substitute the proportion value to find the expected number:
- Expected number = (5 / 7) * 980
4. Calculate the expected number:
- Expected number = (5 * 980) / 7
5. Simplify the expression:
- Expected number = 700
6. Finally, the predicted number of teens who would do homework every night out of 980 is approximately 700 based on the given information.

Answer:

yes gross margin increased

Step-by-step explanation:

Final answer:

a) Yes, gross margin increased

Switching the menu items resulted in an overall increase in gross margin by $10, as the $60 increase in gross margin from cheeseburger sales exceeded the $50 decrease in gross margin from chicken tenders. Therefore, this was a good move.

Explanation:

To determine whether switching the positions of two menu items was a good move, we should calculate the change in gross margin for both items. Gross margin is calculated as sales minus the cost of goods sold (COGS) and reflects the profitability prior to accounting for operating expenses.

For chicken tenders, the drop in sales from $800 to $600 represents a $200 decrease. With a food cost of 25%, the COGS for chicken tenders would be 25% of sales. Before the switch, the COGS was $200 (25% of $800), and after the switch, it became $150 (25% of $600). This means that the gross margin for chicken tenders decreased by $50 (from $600 to $550).

For cheeseburgers, the increase in sales from $500 to $700 is a $200 increase. The food cost being 20%, we had an initial COGS of $100 (20% of $500) and a new COGS of $140 (20% of $700). Consequently, the gross margin for cheeseburgers increased by $60 (from $400 to $460).

Comparing the two changes in gross margin, the increase for cheeseburgers exceeds the decrease for chicken tenders by $10 ($60 increase for cheeseburgers minus $50 decrease for chicken tenders). Therefore, the overall gross margin increased as a result of the switch.

The answer to the question is: a) Yes, gross margin increased.

x=14°

Step-by-step explanation:

(6x + 2°) + (8x + 6°) + (7x + 4°) = 180°

21x + 12° = 180°

21x = 168°

x=14°

Answer:

Step-by-step explanation:

Vertically opposite angles are equal.

∠3 = ∠1

4x = x + 54

Subtract x form both sides

4x - x = x + 54 - x

3x = 54

Divide both sides by 3

3x/3 = 54/3

x = 18

∠1 = x + 54 = 18 + 54 = 72°

4) EFC is straight line

∠CFB +∠BFA +∠AFE = 180°

6x + 2 + 8x + 6 + 7x +4  = 180

6x+ 8x + 7x + 2 + 6 + 4= 180

21x + 12 = 180

21x = 180 - 12

21x = 168

x = 168/21

x = 8

Use the slope-intercept form to find the slope and y-intercept.

Answer

Is (x+3) 2 becase X *2 + 9 is the similar to (x+3)2

The given expression x² + 9 is equivalent to (x+3i)(x-3i).

Hence option B is correct.

The given expression is,

x² + 9

It is equivalent to (x+3i)(x-3i).

When we expand this expression, we get,

x² - 3ix + 3ix - 9i²

Since i² is equal to -1,

Simplify the expression to x² + 9.

The answer option (A) (x+3i)(x-6i) is not equivalent to x² + 9 as it will result in a last term of -18i² instead of +9i².

Similarly, option (C) (x-3i)² is equal to x² - 6ix + 9i², which is also not equivalent to x² + 9.

Option (D) (x+3i)² will result in x² + 6ix - 9i², which is not equivalent to x² + 9 either.

Therefore, the correct answer to the given expression is,

Option (B) (x+3i)(x-3i).
