A ___________ ____________ can be written as a fraction or a ratio.

Answer:

Following are the solution to this question:

Step-by-step explanation:

C'(t) was its time, in years, or t shift of cash per unit. That C'(1980) meaning, therefore, becomes the change of cashier's population to t = 1980.  

They could either use t = 1970 or t = 1990 to approximate the C'(1980) price. When using t = 1970:

[tex]C'(1980) = \frac{[C(1980) - C(1970)]}{[1980 - 1970]}\\\\[/tex]

              [tex]= \frac{(571 - 265)}{10}\\\\ = \$ \ 30.6 \\[/tex]

t = 1990:

[tex]C'(1980) = \frac{[C(1980) - C(1990)]}{[1980 - 1990]}[/tex]

              [tex]= \frac{(571 - 1063)}{ -10} \\\\= \$ \ 49.2[/tex]

Answer:

Future value is $1543.12

Step-by-step explanation:

From the question, present value = $200, rate = 10%, years = 6.

So that future value of ordinary annuity can be calculated by,

FV = [tex]\frac{A{[(1+r)^{n} - 1]}}{r}[/tex]

where: FV is the future value, A is the annuity, r is the rate, and n is the number of years.

FV = [tex]\frac{200[(1+0.1)^{6}-1] }{0.1}[/tex]

    = [tex]\frac{200[1.1^{6}- 1] }{0.1}[/tex]

    = [tex]\frac{200*0.771561}{0.1}[/tex]

    = [tex]\frac{154.3122}{0.1}[/tex]

FV = $1543.122  

The future value of the ordinary annuity is $1543.12.

Answer:

Use the formula  

a n = a 1  r n  − 1

to identify the geometric sequence.

a n =  1.5 ⋅ 2 n − 1

Answer:

n x 2 = x

Step-by-step explanation:

This is the answer because:

1) 1.5 x 2 = 3

2) 3 x 2 = 6

3) 6 x 2 = 12

Therefore, the pattern in this sequence is n x 2 = x

Answer:

[tex]\sqrt{\frac{3x}{3} } + \frac{10}{109} x[/tex]

Step by step:

[tex]\sqrt{x-\frac{3}{7}[/tex] = [tex]\sqrt{\frac{49x-21}{7} }[/tex]

[tex]\sqrt{\frac{49x-21}{7} }[/tex] ÷ 12x+7=[tex]\sqrt{\frac{7x-3x}{12}} + 7[/tex]

[tex]\sqrt{\frac{7x-3x}{12}} + 7[/tex] ÷ 76.3x = [tex]\sqrt{\frac{3x}{3} } + \frac{10}{109} x[/tex]

Answer:

multiplicative inverse of 0.13 is -100/30

The required inverse of 0.13 is 1 / 0.13.

Given that,
To find the multiplicative inverse of 0.13.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The inverse of the particular number is that number when it is multiplied by the number that gives the unit. i.e. ab = 1

Here,
Let the required multiplicative inverse be x,
The product of a number and its multiplicative inverse is equal to 1
So,
0.13*x = 1
x = 1 / 0.13

Thus, the required inverse of 0.13 is 1 / 0.13.

Answer:

1.666......

( 1.6 recurring).

Step-by-step explanation:

As both numbers are multiples of 10 it makes it a bit easier to divide both by 10 to give 25 and 15. This will give the same result as 250/150.

Now do a long division , 25 divided by 15:

        1 .66                    <-----------  25 / 15 = 1 .  1*15 goes below the 25.

    -------------------------

15 ) 25.0

       15      <---------- subtract 25 - 15 = 10

        100 <- bring down the zero(after the decimal point) & append to 10

          90 <  15 divides into 100 6 times to give 90 . Place 6 above line.

           100   < subtract 100 - 90 to give 10 then add 0

             90 < as before 100/15 = 6  to give 6*15 = 90

If you carry on as above you'll see that we get 1.6666...  and we could go on for ever. This is a recurring decimal and is usually written as 1.6 with a bar above the 6.

Answer:

The answer is B.

Step-by-step explanation:

In order to solve this problem, you need to combine like terms, which in this case, are the x's. So, if you add the numbers with the x's together, you get 3x + 12y. The 12y remains untouched because there are no other terms with the same variable.

Answer:

Yes, they are coterminal.

Step-by-step explanation:

Coterminal angles are angles that are in multiples of -360 degrees or +360 degrees away from the initial angle.

Therefore, the easiest way to check if an angle is coterminal is set up an equation.

[tex]x + 117 = 477\\\\360 + 117 = 477\\\\477 = 477 \ \checkmark[/tex]

We get a true statement, which means that 117 is a coterminal angle of 477 and 477 is a coterminal angle of 117.

We can also determine the value in radians.

[tex]\displaystyle117 \times \frac{\pi}{180}\\\\\frac{117\pi}{180} = \frac{13\pi}{20}[/tex]

117° in radians is [tex]\displaystyle\frac{13\pi}{20}[/tex]. Coterminal angles for radians are multiples of [tex]2\pi[/tex], either negative or positive.

However, we also need to determine the value of 477 in radians too.

[tex]\displaystyle477\times\frac{\pi}{180}\\\\\frac{477\pi}{180} = \frac{53\pi}{20}[/tex]

So, if we add [tex]2\pi[/tex] to [tex]\frac{13\pi}{20}[/tex]:

[tex]\displaystyle\frac{13\pi}{20} + 2\pi\\\\\frac{13\pi}{20} + \frac{40\pi}{20} = \frac{53\pi}{20}[/tex]

Therefore, even in radians, 477° is an angle coterminal to 117°.

You are given 117°.

To find angles that are coterminal with 117°, we do the following:

117° + 360° = 477°

117° - 360° = 243°

As you can see, when we added 117° to 360°, we got 477°.

To answer your question, YES.

You now know that 117° and 477° are coterminal angles.

Keep in mind that 477° is not the only coterminal angle to 117°.

Step-by-step explanation:

•the probability of the selected flight arriving on time: 820/1000 = 0.82

•find the probability of the flights not being selected by subtracting 0.82 from 1.00: 1.00-0.82=0.18

•now you look for the answer that equals to 0.18

50/1 =50 nope

9/50 =0.18 yes

41/50 =0.82 nope
