Whats the answer to b and c

Answers

The opposite of an angle around a point is always the same, so we know the unlabelled angle is also worth 43. Then, do 43 + 43 which is 86. Next, note that angles around a point all add up to 360. What we need to do is find the total of c and b, which is 360 - 86. Therefore, 274 is the total of b and c. Finally, half 274 to find both individual values. That means b = 137 and c = 137

Answer: c=137

b=137

What is the Leading Coefficient of 3x^6-2x^9+5x-12 when written in Standard Form?

ASAP!!!!

Answers

Answer:

-2

Step-by-step explanation:

Given polynomial:

3x⁶ - 2x⁹ + 5x - 12

Convert this into standard form, order in descending powers:

-2x⁹ + 3x⁶ + 5x - 12

The leading term, -2x⁹ is the one with the greatest power. Its coefficient, -2 is the leading coefficient.

$\\ \rm\longmapsto 3x^6-2x^9+5x-12$

Write in standard form

$\\ \rm\longmapsto -2x^9+3x^6+5x-12$

9>6>1

-2x has greatest degree hence leading coefficient is -2.

it’s just a straight line

Its straight
If it were a right angle it would be at a 90 degree angle
acute angle is less than 90 degree
Obtuse is more than a 90 degree angle
Straight is an angle that is flat and stays at a 180 degree
A C E is a straight angle bc it is at an 180 degree and is flat
If it were something like BCE or ACD it would be a acute angle

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?

Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?

A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.

Answers

Answer:

To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.

Therefore, the correct selling price is $4.

The manager's likely error was that they set the selling price at the cost (option C).

Step-by-step explanation:

The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Cost of item = $6

Markup = 67%

67% of $6 ⇒ 0.67 x 6 = $4.02

Add the markup in the cost = $6 + $4.02 = $10.02

Round to nearest dollars = $10.2 ≈ $10.

The manager put $4 which is a markup instant of the selling price of $10.

Hence "The correct selling price is $10 and the manager set the selling price at the markup".

Part C: Compare the ratio of the areas to the scale factor. Show every step of your work. (4 points)
PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

Step-by-step explanation:

18-2.5+7 there s your helllppppppppppp

Part A: The original triangle has a base of 18 feet and a height of 7 feet. To create the 2:5 scaled version of the deck, we can simply multiply the base and height of the original triangle by the scale factor of 2/5.

New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet

Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.

Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:

Area = (1/2) x base x height

Area = (1/2) x 18 x 7 = 63 square feet

To find the area of the new deck, we can use the same formula and plug in the new dimensions:

Area = (1/2) x 7.2 x 2.8 = 11.88 square feet

Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.

Part C: The ratio of the areas is:

63/11.88 = 5.303

The scale factor is:

2/5 = 0.4

To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:

5.303/0.4 = 13.2575

Therefore, the ratio of the areas is 13.2575 times the scale factor.

1. -15 ≥ x - 7

2. 6y < -48

3. -2y - 4 > 18

4. 2n + (-8) > 12

5. 2n - 6 ≤ -10

6. -5n + 15 ≥ -60

7. -1 + 5n ≤ -26

Answers

Answer:

1. x ≤ -8

2. y < -8

3. y < -11

4. n > 10

5. n ≤ -2

6. n ≤ 15

7. n ≤ -5

Step-by-step explanation:

Your goal is to get just the variable on one side of the inequality!

For example, take -2y - 4 > 18.

Add 4 to both sides. So... -2y - 4 + (4) > 18 + (4)

Now you get -2y > 22. Since y isn't by itself, let's divide both sides by -2.

So, (-2y / -2) > (22 / -2)

Anytime you're dividing something by a negative, remember to FLIP THE SIGNS. So instead of a greater than, it will now be a less than sign <.

Now you get, y < -11

Answer:

1 13/24

Step-by-step explanation:

First we need to find the LCD (lowest common Denominator) which will be 24. When we multiply 8 x 3 = 24 we will also multiply 5 by 3 which equals 15. So 5/8 = 15/24. Then we multiply 12 x 2 = 24, and again we also multiply the numerator by the same number which is 11 x 2 = 22. So 11/12 = 22/24.

Now that we have the LCD then we can add up the two. So 15/24 + 22/24 = 37/24. Now we need to simplify that to 1 13/24. Thank you.

A box contains 18 violet tops, 15 red tops, and 9 white tops. Identify the ratio of white tops to violet tops in all three forms.

Answers

Answer:

top option:

"9/15, 9 to 15, 9:15

1/2, 1 to 2, 1:2"

Step-by-step explanation:

First, create a ratio of white tops to violet tops using the given information:

9 white tops : 18 violet tops

We can simplify this by dividing both sides by 9 to get:

1 white top : 2 violet tops or 1 : 2

So, the answer is the topmost option or

"9/15, 9 to 15, 9:15

1/2, 1 to 2, 1:2".
