HELP ME -(6x+7)+8=19?

Use cos2x =1-2sin^2x

1+sinx- (1-2sin^2x) = 1+ sinx -1+2sin^2x

=sinx+2sin^2x=sinx(1+2sinx)

Therefore

Either sinx=0 or 1+ sin2x =0

X=npi or sin2x=-1

Sin2x=sin 3pi/2

2x= npi +(-1)^n3pi/2

x=npi/2 + (-1)^n 3pi/4

Hi, there

Question:Ms. Lynch has 21 coins in nickels and dimes. Their total value is $1. 65. How many of each coin does she have?

Explanation:

1.65 x 21

Answer 34.65

Hi!

Ms. Lynch has 21 coins in nickels and dimes. Their total value is $1. 65. How many of each coin does she have?

12 x 0.1 = 1.2

9 x 0.05 = 0.45

1.2 + 0.45 = $1.65

Answer:

She has 12 Dimes and 9 Nickels!

Final answer:

By adding the two numbers and rounding, we first get -32.1 for the rounding to the nearest tenth and then the same result, -32.1, when rounding to the nearest hundredth.

Explanation:

To perform the indicated operation and round the result first to the nearest tenth and then to the nearest hundredth, we begin by adding the two numbers: -49.256 + 17.197. The sum of these numbers is -32.059. To round to the nearest tenth, we look at the hundredths place, which is 5, so we round up, resulting in -32.1. Next, to round to the nearest hundredth, we consider the thousandths place, which is 9, so we again round up, but since we're already at 9 in the hundredths place, the result remains -32.1.

175/ 6 = 29.1

So you would need at least 30 tables.

Hope this Helps!!

So to figure this out first setup the equation to do so take note of the amount of people and how many can sit at a table.

6 and 175

so now make the equation which will be

175/6=29.1

Round to the most is 30. So 30 tables are needed to seat 175 people.

Answer:

FALSE

Step-by-step explanation:

The statement 'theoretical probability and experimental probability are the same' is generally false. Theoretical probability is what we expect to happen, while experimental probability is based on actual results from experiments. With more trials, these two probabilities tend to get closer, thanks to the Law of Large Numbers.

B. Homeowners pay additional property taxes

-Mabel <3

Owning a home can lead to a lack of flexibility, high maintenance costs, and financial risks associated with changes in the housing market.

A significant disadvantage of buying and owning a home is the commitment and reduced flexibility compared to renting. When you purchase a home, it becomes a major part of your portfolio, any change in the housing market can directly affect your financial status. Not to mention, if you need to move for a career opportunity or a change in life circumstances, it can be challenging to sell the house, especially if the market conditions are unfavorable.

Furthermore, home ownership often comes with substantial maintenance costs and responsibilities. Unlike renting, where the landlord typically handles maintenance tasks, as a homeowner, these responsibilities and costs are up to you. This can include routine tasks such as gardening and cleaning, to significant unexpected costs like roof replacement or plumbing issues.

Additionally, despite the potential financial return of selling the house in the future for more than you paid for it, this is not guaranteed. The housing market can fluctuate and you may not always make a profit on the resale of your home.

A number can be 10.

You can add 7 + 3 to get 10.

Answer:

10 is the correct answer

Step-by-step explanation:

The slope is 9/11 because if you use the formula (change in y)/(change in x), you would get -18/-22 and then if it were to be simplified, it would be 9/11

If there is 2 field trips with 23 students and each student costs $5 dollars. So for the 1st trip it will be 23x$5

1st trip- $115

And on the second trip its the same because there is 23 students that cost 5 dollars so it will be 23x5

2nd trip- $115

To find out the total of both trips youd add 115+115/

In total, for both trips it will cost $230 dollars.

The scale is : 1 in : 2.5 ft

Step-by-step explanation:

An architect notices that the scale on a blueprint he is using has been torn off.

However, he sees that a 12.5-ft. wall that has been built is 5 in. long on the blueprint.  

Let the scale be x

[tex]\frac{5}{12.5} =\frac{1}{x}[/tex]

So, scale = [tex]x=\frac{12.5}{5}[/tex] = 2.5

So, the answer is : 1 in : 2.5 ft

To find the sale price of an item that is normally $130 with a 30% markdown, calculate the discount amount ($39) and subtract it from the original price to get a sale price of $91.

The question asks to calculate the sale price of an item after a 30% markdown. To determine the sale price, you have to first calculate the discount amount and then subtract it from the original price of the item. Here's how you do it:

For an item that is normally sold for $130 and is marked down 30%, the sale price can be calculated as follows:

[tex]x=0.\overline{8}\\\\10x=8.\overline{8}\\\\10x-x=8.\overline{8}-0.\overline{8}\\\\9x=8\\\\x=\dfrac{8}{9}[/tex]

The width is 8 in.The lenth is 4 in.

Yeah, its all correct

It's all correct, but I'm not really sure about the drawing part because I can't see it all, although I think you did a great job :)

If you mean 5 and 1/5 then that is the simplest form.

first, rearrange the equation like this  

5 + z -4z = 8  

Then, simplify the "z"s Then, subtract 5 from both sides  

-3z = 3  

Then, divide both sides by -3  

z = -1  

To check  

-1 + 5 - 4(-1) = 8  

-1 + 5 + 4 = 8  -1 + 9 = 8  

8 = 8  

20 - (3 * 2.75) - 10.99

20 - 8.25 -  10.99

12.75 - 10.99
