Help please i really need help with this problem it’s so hard please please help

Answer:

x = 12

Step-by-step explanation:

Here we go!

What we know:

So 7x and 8x are part of a same side interior angle. meaning, they add up to 180°!

[tex]8x + 7x = 180[/tex]

Combine like terms

[tex]15x = 180[/tex]

Divide 15 from both sides

[tex]x = 12[/tex]

Let's check our work:

plug in x

7(12) + 8(12) = 180

multiply

84 + 96 = 180

add

180 = 180

Answer:

6.1

Step-by-step explanation:

anything 5 and over you round to one, so .08 turns into .1 :) glad i could help

The given decimal number is rounded to the nearest tenth as 6.1.

The given decimal number is 6.08.

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

Here, in 6.08 digit in the hundredths place is 8, which is greater than 5.

So, the digit in the tens place increased by 1 and digits after tens place becomes zero.

That is, 6.10

Therefore, the given decimal number is rounded to the nearest tenth as 6.1.

Divided sides by b

[tex] \frac{A}{b} = h \times \frac{b}{b} \\ [/tex]

thus ;

[tex]h = \frac{A}{b} \\ [/tex]

*see attachment for the drawing

Answer:

No. The width is longer than the space available along the wall next to the bookshelf.

Step-by-step explanation:

The scale of the length of the space the piano is to occupy along the wall close to the bookshelf = 12 cm - 4 cm = 8 cm

Actual length of the space given a scale of 1 cm to 6 in: 6*8 = 48 in

The piano is said to have a width of 54 inches, therefore, it will not fit along the wall next to the bookshelf. The space available along the bookshelf is just only 48 inches long, which is less than the width of the piano.

Answer:

No

Step-by-step explanation:

It does not fit

Answer:

$63.60

Step-by-step explanation:

4 board games are $15 each, multiply 4*15 = 60.

There is a 6% sales tax, so it is 6% extra. To calculate 6% as a decimal, divide it by 100, so 6/100 = 0.06. Now that it is 0.06 extra, you add 0.06 to 1.00 because 1.00 is the 100% of the price (the $60). So now it is 1.06 of the price. Multiply 60 * 1.06 and you get $63.60

Answer:

60.36 cents

Step-by-step explanation:

you have to times 60 by .6 then you get 36 and that is how much taxes cost.

Answer:

$5

Step-by-step explanation:

You will multiply $8 by 3 and subtract 44 by that number. You will then divide that number by 4.

Answer:

$5 each

Step-by-step explanation:

total of $44.00

3 adults * $8.00 = $24

$44.00 - $24.00 = $20

$20 * 4 children = $5 each

Answer:

$8,000 in Treasury bills

$7,000 in Treasury bonds

$5,000 in corporate bonds

Step-by-step explanation:

Let the amount to be invested in treasury bills be $x , the amount to be invested in treasury bonds be $y

From the question, we understand that the amount she will invest in corporate bonds will be $3000 less than the amount in treasury bills;

So mathematically, this will be $(x - 3000)

So therefore, the amount invested in each will be;

x + y + x-3000 = 20,000

2x + y = 20,000 + 3000

2x + y = 23,000 ••••••••(i)

Let’s now work with the simple interests;

For treasury bills;

5% = 5/100 * x = 5x/100

For Corporate bonds ;

10% = 10/100 * (x -3000) = (x-3000)/10

For Treasury bonds 7%

7% = 7/100 * y = 7y/100

Adding all gives the total interest;

5x/100 + 7y/100 + (x-3000)/10 = 1390

Multiply through by 100

5x + 7y + 10(x-3000) = 1390 * 100

5x + 7y + 10(x-3000) = 139,000

5x + 7y + 10x -30,000 = 139,000

15x + 7y = 139,000 + 30,000

15x + 7y = 169,000 •••••••••(ii)

So we have two equations to solve simultaneously;

From i, y = 23,000 - 2x

Put this into ii

15x + 7(23,000 -2x) = 169,000

15x + 161,000 - 14x = 169,000

x + 161,000 = 169,000

x = 169,000 - 161,000

x = $8,000

y = 23,000 - 2x

y = 23,000 - 2(8,000)

= 23,000 - 16,000 = $7,000

So the last investment amount is x-3000 = 8,000 -3,000 = $5,000

Answer:

x is 75 degrees and y is 43 degrees

Step-by-step explanation:

Answer: 75%

Step-by-step explanation:

15/20 = 3/4 or 75%

Answer:

A) 7,950$, B) 7,963.73$, C) Since daily interest means that 6%/365 of 7500 will be added and compounded every day for the given amount of time(in this case, one year), while annual interest means that 6% of 7500 will be added and compounded yearly for the given amount of time(I'm this case, one year).

Step-by-step explanation:

Given the compound interest formula, A = P(1+r/n)^nt, where A = total amount(final amount), P = principle or amount of money deposited(starting amount), r = annual interest rate(percent interest in respect to t ; decimal = %/100), and n = conversion rate(number of times compounded per t; how much is it compounded)

t = time(time in respect to years ; how long it is compounded).

For A) A = 7500( 1 + 6%/365 ) ^ 365 = 7500(1 + 0.06/365) ^365 = 7500(1 + 0.00016438356..)^365= 7500(≈1.0001644^365) = 7500(100.01644%^365) = 7500(≈106.183%) = 7963.725 ≈ 7963.73$

For B) A = 7500( 1 + 6% ) ^ 1 = 7500(1 + 0.06) = 7500(1.06) = 7500(106%) = 7950$

C) this is because compounding something with a higher frequency leads to a different percentage (as n approaches infinity with time proportional to the annual rate, the ratio between the principle and total amount are proportional to e)

Answer:

9.6*10^negative 3

Step-by-step explanation:

Let each ticket cost x

Answer for Part A

6x + 6% (6x) = 165.36 dollars.

Answer for Part B

6x + 6/100 * 6x = 165.36

6x + 36/100 x = 165.36

6x + 0.36 x = 165.36

6.36x = 165.36

x = 165.36/6.36

x = 26 dollars for each ticket.

Part C

Service charge = 165.36 - 6*26

Service charge = 165.36 - 156

Service charge = 9.36
