Answer:

30%

Step-by-step explanation:

To express percentage as a fraction, the denominator must be 100.

Given ,

[tex]\frac{18/60}{60/60}\\= \frac{0.3}{1} \\= 0.3 * 100\\= 30%[/tex]

Answer:

1) Percent of skateboards that are longboards is 18÷60 or 30%

2) Number needed for equivalent ratio is 30 longboards

Step-by-step explanation:

1) Percentage= part divided by whole

18÷60 = 0.3

0.3 = 30%

2) Create a proportion, let x = # longboards needed for a equivalent ratio

(18÷60)=(x÷100)

x=30

Step-by-step explanation:

This program simplifies our complex monetary system by familiarizing users with common combinations of coins and bills that are equivalent in value. Starting with five pennies equal one nickel, the program works up to equivalents for a twenty dollar bill.

Answer:

$1.05

Step-by-step explanation:

1 dime = 10 cents so 7 dimes = 70 cents
1 quarter = 25 cents

Therefore 10 cents + 7 dimes + 1 quarter = 10 + 70 + 25 = 105 cents = $1.05

Split the integrand into partial fractions.

[tex]\dfrac{9x+2}{x^2+x-6} = \dfrac{9x+2}{(x-2)(x+3)} = \dfrac a{x-2} + \dfrac b{x+3}[/tex]

[tex]\implies 9x+2 = a(x+3) + b(x-2) = (a+b)x + (3a-2b)[/tex]

[tex]\implies \begin{cases}a+b=9 \\ 3a-2b=2\end{cases} \implies a=4,b=5[/tex]

Then we have

[tex]\displaystyle \int \frac{9x+2}{x^2+x-6} \, dx = 4 \int \frac{dx}{x-2} + 5 \int \frac{dx}{x+3} \\\\ = \boxed{4\ln|x-2| + 5\ln|x+3| + C}[/tex]

which follows from the result

[tex]\displaystyle \int \frac{dx}x = \ln|x|+C[/tex]

Answer:

x = √6 or - √6

Step-by-step explanation:

equation: -7x + 6 = x² - 7x

switch sides:

x² - 7x = -7x + 6

Add 7x to both sides,

x² - 7x + 7x = -7x + 7x + 6

x² = 6

For x² = f(a) the solution are x = √f(a), -√f(a)

x = √6 , x = - √6

Answer:

-7x + 6 = x² - 7x

-7x + 7x +6 - x² = 0

0 + 6 - x² = 0

-x² + 6 = 0

-x² = (-6)

x² = 6

x = ±√6

x =√6 or x = -√6

Answer:

You divide both the numerator and the denominator by the same number until they can't be reduced any further.

Answer:

Make sure to divide the upper number and the lower number (in position) to a number which can't be futher divided. It will be of numbers which are really small numbers. like 4/2 will be divided by 2 to get the simplified answer of 1/2

Answer:

-8

Step-by-step explanation:

3 + -4 - 7

3 - 4 - 7

-1 - 7

-8

Answer: -8

Step-by-step explanation:

3+(-4)-7

Whenever you have a +(- something), it ALWAYS becomes a -

So 3+(-4)= 3-4

Now we have:

3-4-7

PEMDAS states that you must do the subtraction  from left to right. So you start with the 3-4.

3-4-7

-1-7

-8

Whenever you have a negative number minus a number , the result will always be negative.

Hence, thats why the answer is -8

Answer: I would say A or C bc they are similar but C seems more reasonable.

Answer: 8,230,472,011

Explanation:

billions: __8

millions: 230

thousands: 472

ones: 011

Answer:

8,230,472,011

Step-by-step explanation:

Answer:

The answer is no because for 1 hour he gets 20 dollars and for 2 hours he gets 30$ (which is less for working 2 hours). So, if you multiply 2 hours with 20 dollars, you should get 40, not 30. So therefore, it is not proportional. And same for 3 hours: multiply 3 with 20 to get 60, not 50.

Answer:

$ 2155.62

Step-by-step explanation:

regular pay rate = 11.10

overtime pay rate = 1.8 * 11.10

142 *  $11.10        +         29 * ( 1.8 * $ 11.10)        =   $  2155.62

Answer:

4

Step-by-step explanation:

Since the question does not specify if you are rounding up or down, just round down to four from 4 1/6. 4 1/6 is closer to 4 than it is to 4 3/6 or 4 1/2.

1 month is aprox. 30 days, so

To find john's daily salary:

For a month, the salary is 4,410 rupees, so for a day how much?

days     salary

30          4,410    (This is how I learnt to solve these kind of problems)

1               ?

Then you crisscross the equation which becomes

4,410/30=147 rupees

To find weekly salary:

we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?

You multiply the salary for one day and the number of days: 147×7=1,029 rupees

To find salary for a year (annual):

we now know the salary for one day so we can say:  For a day, the salary is 147 rupees, so for 365 days (1 year) how much?

You multiply the salary for one day and the number of days: 147×365=53,655 rupees

Hope it helps!

Step-by-step explanation:

plug in x and y into the equation

Answer:

1. 96%

2. $6000

3. 176

4. 20%

Step-by-step explanation:

1. 1/5 of 80% is 16%. 80+16=96

2. 25% of 8000 is 2000. 8000-2000= 6000.

3. 10% increase of 200 is 20. 20+200=220. 20 percent of 220 is 44. 220-44=176

4. if you increase the original salary by 20%, then decreasing it by 20% of the new salary will give you the old salary.

Answer:

one paperback = 0.6 pounds

one textbook = 3.6 pounds

Explanation:

Let the mass of one paperback be 'p' and one textbook be 't'.

Equation one:

sum of mass = total mass in box

Equation two:

make 't' subject

Insert this into equation one:

20p + 9(5.1 - 2.5p) = 44.4

20p + 45.9 - 22.5p = 44.4

20p - 22.5p = 44.4 - 45.9

-2.5p = -1.5

p = 0.6

The weight of 1 paperback is 0.6 pounds.

The weight of 1 textbook:

t = 5.1 - 2.5p

t = 5.1 - 2.5(0.6)

t = 3.6

The weight of 1 textbook is 3.6 pounds.
