Answer:

Step-by-step explanation:

it is important to note that 40/8 = 5.

A real number is one that can be found on the number line, and 5 can be.

A rational number can be made by dividing two integers (40 by 8 in this case).

5 is a whole number since it does not have a decimal/fractional part

an integer is a whole number which is positive/negative (5 is positive in this case)

18, 26, 34, 42, find the 52nd term and the explicit formula

daser333 [38]

We have 26 - 18 = 8; 34 - 26 = 8; 42 - 34 = 8; (an arithmetic progression)
We use the formula an = a1 + (n-1)x8 (the explicit formula)
So, an = 18 + (n-1)x8 ;
Then, an = 8n + 10;
Finally, a52 = 8x52 + 10 = 426 (the 52nd term);

Determine the measure of an interior angle of the named regular polygon. If a side of the polygon is extended, determine the sup

ladessa [460]

Answer:

A) Each interior angle of the Regular Hexagon = 120°

B)The measure of the supplementary angle of an interior angle is 60°

Step-by-step explanation:

Regular Hexagon : A 6 sided polygon which has all 6 interior angles as EQUAL is called a regular hexagon.

So, here are 6 interior angles of the hexagon are equal.

Also, Sum of all interior angles of an hexagon = 720°

Let us assume the each angle of the hexagon = m

⇒ m + m + m + m + m + m = 720°

or, 6 m = 720°

or, m = 720° / 6 = 120°

⇒ Each interior angle of the Regular Hexagon = 120°

Now, a side is extended to form an exterior angle.

Let us assume the measure of that exterior angle = k

⇒ k + m = 180 ° ( as k and m are SUPPLEMENTARY ANGLES)

or, k = 180 - 120 = 60 °

or, k = 60 °

Hence, the measure of the supplementary angle of an interior angle is 60°

The actual amount that should be credited is $757.58.

Solution:

Given that,

2% Discount if paid in 10 days.

1% Discount if paid in 15 days, (but greater that 10 days)

Net due in 60 days.

That is,

$\bold{1400\times0.98 = 1372}$ will close the acount on days 1-10

$\bold{1400\times0.99 = 1386}$ will close the acount on days 11-15

And August 8 is Day 15 and falls under the 1% discount rule.

Therefore, we have to divide the partial payment by the complement of the discount rate.

$\bold{\Rightarrow\frac{750}{0.99} = 757.58}$ from the balance, and $\bold{1400.00 - 757.58 = 642.42}$ is due by day 60.
