You can multiply $160 by 2 because 16 is 8 * 2. 16 pastries would then be $320.

Or, you can divide $160 by 8, to get the price per pastry. You would get $20 per pastry, and multiply it by 16, which equals $320

(You would get the same answer either way)

16 pastries would cost the double cost of 8 pastries because 8 is half of 16
, if 8 pastries cost $160 then 16 pastries would cost $320.

Find the series shown.
solmaris [256]

Answer:

C 11+13+15+17+...

Step-by-step explanation:

Consider the series

\sum\limits_{n=3}^{\infty}(2n+5)

The nth term of series is a_n=2n+5

The bottom index tells you that n starts changing from 3, so

a_3=2\cdor 3+5=11\\ \\a_4=2\cdot 4+5=13\\ \\a_5=2\cdot 5+5=15\\ \\a_6=2\cdot 6+5=17\\ \\...

Thus, the sum of all terms is

11+13+15+17+...

Ok need help this is the question :Use the Pythagorean theorem to write an equation for the distance Jane's trainer bikes.
IRINA_888 [86]

Answer:

<em>Jane traveled 8 miles farther then her trainer</em>

Step-by-step explanation:

<u>The Pythagora's Theorem</u>

In any right triangle, the square of the measure of the hypotenuse is the sum of the squares of the legs. This can be expressed with the formula:

c^2=a^2+b^2

Where

c = Hypotenuse or largest side

a,b = Legs or shorter sides

Jane's path from the Health Club to the end of her route describes two sides of a right triangle of lengths a=16 miles and b=12 miles.

Her total distance traveled is 16 + 12 = 28 miles

Her trainer goes directly from the Health Club to meet her through the hypotenuse of the triangle formed in the path.

We can calculate the length of his route as:

c=\sqrt{16^2+12^2}

c=\sqrt{256+144}=\sqrt{400}=20

c = 20 miles

The difference between their traveled lengths is 28 - 20 = 8 miles

Jane traveled 8 miles farther then her trainer

A substance is tested and has a ph of 7.0. how would you classify it? a. a strong acid b. a strong base c. a weak acid d. neutra
Eddi Din [679]

<u>A substance is tested and has a </u><u>Ph of 7.0</u><u>. It would be </u><u> a weak acid. </u>

<u>The correct option is </u><u>(c) a weak acid .</u>

<u></u>

What is the nature of substance if the pH is less than 7?

  • Acidity is defined as pH below 7. More than 7 pH is considered basic.
  • Each whole pH number below 7 is ten times more acidic than the next higher value since the pH scale is logarithmic.
  • For instance, pH 4 is 100 times (10 times 10) more acidic than pH 6, while pH 5 is ten times (10 times) more acidic than pH 4.

What is pH?

  • The pH scale determines how acidic or basic water is.
  • The range is 0 to 14, with 7 representing neutrality.
  • Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
  • In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

Which is the best estimate of the measure of this angle?
puteri [66]
A straight line is 180° and this is less than that but it’s more than 90°, 105° is close to 90 and this is a bit bigger so your best estimate is
