Work out the size of angle x

Answer:

Step-by-step explanation:

New price = (1 + 5%) x old price

New price = 1.05 x old price

old price = 2.3 / 1.05

Old price = £2.19

9514 1404 393

Answer:

  £46

Step-by-step explanation:

The increase is ...

  0.05 · price = £2.30

Multiplying by 20 gives ...

  price = 20(£2.30) = £46.00

The price of the ticket before the increase was £46.00.

Answer:

[tex]\$4453.52[/tex]

Step-by-step explanation:

Principal amount (P) = $3,000

Rate of interest (R) = 2.5%

Time period (T) = 4 years

Future value in 4 years = [tex]P(1+\frac{R}{100})^{4T}[/tex]

Put [tex]P=3000\,,\,R=2.5\,,\,T=4[/tex]

Therefore,

Future value in 4 years = [tex]3000(1+\frac{2.5}{100})^{4(4)}=3000(1.025)^{16}=\$4453.52[/tex]

Answer:

26cm

Step-by-step explanation:

P= all sides

p=6+3+2+4+2+3+6

should get 26 then add the correct symbol...so put 26 cm

Answer:

  25%

Step-by-step explanation:

Apparently, we're to assume that anything not spent is saved.

Let Hideo's income be 1. Then Akira's income is 5/8. Akira's expenses are 60% = 3/5 of that value, so ...

  Akira's expenses = (3/5)(5/8) = 3/8  . . . . . of Hideo's income

Hideo's expenses are twice this amount, so ...

  Hideo's expenses = (2)(3/8) = 3/4 . . . . . of Hideo's income

That means Hideo saves 1 -3/4 = 1/4 = 25/100 = 25% of his income.

Hideo saves 25% of his income.

Answer: the x values

Step-by-step explanation:

Answer:

2(4x+3)

Step-by-step explanation:

We need to find what is the most common between 8x and 6. The only number here is 2 that is common between them.

That will be on the outside of the bracket.

So if we divide 2 from both terms.

8x ÷ 2 = 4x

6 ÷ 2 = 3

Let's put it all together.

2 first.

Our x term and 3 in brackets.

2 (4x+3)

There we go!

Answer:

f(9) = 50

f(-10) = -64

Step-by-step explanation:

Given the function

f(x) = 6x - 4

f(9) = 6(9)-4

f(9) = 54-4

f(9) = 50

b)f(-10)

f(-10) = 6(-10) - 4

f(-10) = -60 -4

f(-10) = -64

Answer:

  g) $6000 ($528.18 to principal)

  h) $9,471.82

  i) $5471.82

Step-by-step explanation:

You can make a chart, as you have started. Such a chart is often referred to as an amortization schedule. The basic idea would be to show how each payment is distributed to interest and principal. The attached shows such a spreadsheet (with a few rows hidden). It is described in more detail below.

__

g) The total amount paid is 24 payments of $250 each, so $6000. These payments reduced his amount owed by $528.18. (We don't know if "toward his credit card" means "to the creditor" or "to pay his debt".)

__

h) The amount still owed is $9,471.82 (the ending balance after the 24th payment)

__

i) $5,471.82 went toward interest.

_____

Spreadsheet details

The first "Beg Bal" is the $10,000 owed. Each one after that is copied from the "New Bal" cell on the previous line.

Each "to interest" quantity is the product of the beginning balance and the monthly interest rate. The cell reference to the interest rate needs to be an absolute reference, so it remains the same when copying the formula to other cells.

The "to Principal" amount is the difference between the payment amount and the amount "to interest." The reference to the payment amount cell also must be an absolute reference.

The "End Bal" amount is the difference between the "Beg Bal" and the amount "to Principal".

As you can see, the payment math is not difficult. There is one multiplication (by the interest rate) and the rest is subtraction.

Note that the numbers in this spreadsheet are rounded by the display. In a real payment situation, the interest due amount would be rounded to the penny before being used in other calculations. The way we have done it will result in a few cents difference in the ending balance from the value if the interest were actually rounded at each step.

Answer: Danielle drive for 2 hours

Jamal drives for 2 × 3 = 6 hours

Step-by-step explanation:

Let the number of hours that Danielle used in driving to be represented by x.

Since Jamal drives 3 times the hours that Danielle does. This will be:

= 3 × x = 3x

Since Jamal and Danielle drive for a total of 8 hours. This can be formed into a equation as:

x + 3x = 8

4x = 8

x = 8/4

x = 2

Danielle drive for 2 hours

Jamal drives for 2 × 3 = 6 hours

[tex] \large \boxed{f(8) = 27}[/tex]

Step-by-step explanation:

Goal

Given

[tex]f(x) = \frac{1}{2} {x}^{2} - ( \frac{1}{4} x + 3)[/tex]

Step 1

[tex]f(8) = \frac{1}{2} {(8)}^{2} - ( \frac{1}{4} (8) + 3)[/tex]

Step 2

[tex]f(8) = \frac{1}{2} (64) - ( \frac{8}{4} + 3) \\ f(8) = 32 - ( \frac{2}{1} + 3) \\ f(8) = 32 - (2 + 3) \\ f(8) = 32 - (5) \longrightarrow 32 - 5 \\ f(8) = 27[/tex]

Hence, the value of f(8) is 27.

Answer:

Step-by-step explanation:

The Smith family went out to dinner . The price of the meal was $ 29.85 .

The sales tax was 6 % of the price of the meal .

LEts find sales tax amount sales tax amount = price of meal *

sales tax 6 % ( 0.06 ) = 29.85 * 0.06 = 1.791 sales tax amount = 1.791

Price of the mean with sales tax = 29.85 + 1.791 = 31.641

The tip was 15 % of the meal and the sales tax now we find out tip amount for 31.641 15 % is 15 / 100 = 0.15

Tip amount = 31.641 * 0.15 = 4.74615

Now we add the top amount with 31.641 31.641+ 4.74615 = 36.38715

the Smith family pay for the meal = $ 36.39

Answer:

Step-by-step explanation:

The length of the subway is 900 miles.

So if 1 inch is 45....we want to find it for 900 miles

900/45 = 20

So it will be 20 inches for 900 miles

Check by using ratio

1 : 45

2 : 90

3 : 135

4 : 180

5 : 225

6 : 270

7 : 315

8 : 360

9 : 405

10 : 450

11 : 495

12 : 540

13 : 585

14 : 630

15 : 675

16 : 720

17 : 765

18 : 810

19 : 855

20 : 900

1 - 20 = inches

45 - 900 = miles

So for 900 miles, it will be 20 inches long
