Answer:

-23/5

Step-by-step explanation:

-3/5 + - 8/2

Find the least common multiple of 5 and 2.

That would be 10.

That means we have to multiply the first fraction by 2/2 and the second one by 5/5

-3/5*2/2

Multiply the numerators together and the denominators together.

-6/10

Repeat with the second fraction.

-8/2*5/5

-40/10

Our new expression is

-6/10+-40/10

-46/10

Simplify

-23/5

As a mixed number that would be:

-4 3/5

a daily newspaper has 10225 subscribers when it began publication. six years old later it has 8200 subscribers what is the avera

seraphim [82]

Answer:

The rate of change in number of subscriber for the six years is 3.62%

Step-by-step explanation:

Given as :

The initial subscriber of newspaper = p = 10225

The subscriber of newspaper after 6 years of publish = P = 8200

The time period = t = 6 years

Let The average yearly rate of change = r%

Now, According to question

The subscriber of newspaper after n years = initial subscriber × $(1-\dfrac{\textrm rate}{100})^{\textrm time}$

Or, P = p × $(1-\dfrac{\textrm r}{100})^{\textrm t}$

Or, 8200 = 10225 × $(1-\dfrac{\textrm r}{100})^{\textrm 6}$

Or, $\dfrac{8200}{10225}$ = $(1-\dfrac{\textrm r}{100})^{\textrm 6}$

Or, 0.80195 = $(1-\dfrac{\textrm r}{100})^{\textrm 6}$

Taking power $\dfrac{1}{6}$ both side

So, $(0.80195 )^{\frac{1}{6}}$ = $((1 - \frac{r}{100} )^{6})^{\frac{1}{6}}$

Or, 0.9638 = 1 - $\dfrac{r}{100}$

Or, $\dfrac{r}{100}$ = 1 - 0.9638

Or, $\dfrac{r}{100}$ = 0.0362

Or, r = 0.0362 × 100

i.e r = 3.62

So, The rate of change in subscriber = 3.62%

Hence, The rate of change in number of subscriber for the six years is 3.62% . Answer

Find the HCF and LCM of 126 and 234?

Leni [432]

Answer:

Below in bold.

Step-by-step explanation:

Find the prime factors:-

126 = 2 * 3 * 3 * 7

234 = 2 * 3 * 3 * 13

So the GCF = 2 * 3 * 3 = 18.

The LCM = 2 * 3 * 3 * 7 * 13

= 1638.

The functions f(x) and g(x) are described below:

sesenic [268]

Suppose that the function f(x) is the parrent function and the graph of the function g(x)=f(x)-a can be obtained from the graph of the parrent function f(x) by shifting down a units.

Rewrite the expression for the function $g(x)$ in the following way:

$g(x)=32x-9=32x+8-8-9=32x+8-17=f(x)-17.$

This shows that the shift down is made by 17 units.

Answer: 17 units

What is the total price of a boat with an original price of 12916$, if it is sold at a 15% discount? The sales tax rate is 3

Dmitriy789 [7]

Answer:

$11390.30

Step-by-step explanation:

Discount

12916 x 0.15 = 1937.4

Discounted price

12916 - 1937.4 = 10978.6

Tax of 3 and 3/4 percent which I think is 0.0375

10978.6 x 0.0375 = 411.6975

Total

10978.6 + 411.6975 = $11390.2975
