We know that the sum of the inner angles of any triangle is 180º

72º + (7x + 3)º + (3x + 5)º = 180º
72º + 7xº + 3º + 3xº + 5º = 180
7xº + 3xº = 180º - 72º - 3º - 5º
10xº = 100º
$x^0 = \frac{100^0}{10^0}$
$x^0 = 10\to\:\boxed{\boxed{x = 10^0}}\end{array}}\qquad\quad\checkmark$

The sum of the external angle (9y + 1)º with inner angle (3x + 5) = 180 °, <span>Replace the measure of "x" found:
</span>
(9y + 1)º + (3x + 5)º = 180º
9yº + 1º + 3xº + 5º = 180º
9yº + 1º + 3.(10)º + 5º = 180º
9yº + 1º + 30º + 5º = 180º
9yº = 180º - 1º - 30º - 5º
9yº = 144º
$y^0 = \frac{144^0}{9^0}$
$y^0 = 16\to\:\boxed{\boxed{y = 16^0}}\end{array}}\qquad\quad\checkmark$

Answer:
<span>The measures of "x" and "y" are respectively: 10º and 16º</span>

(24) $550 at 3% for 3 years

andrew11 [14]

550 * 1.03 = 566.5 (Year 1)

566.5 * 1.03 = 583.495 (Year 2)

583.495*1.03 = 600.99985 (Year 3)

You can safely assume this is your answer: $601.00

How do you estimate? I don't really understand because for one question my teacher said you wouldn't round your numbers, but for

uranmaximum [27]

Answer:

You can round up to tenths, hundredths, thousandths, or tens, hundreds, and thousands. Some numbers, they have remainders when divided, so you would round them up to make them whole numbers or non-repeating decimals.

Hope this helps!!

In a race, Brian Collins has to cross 10 hurdles. The probability that he clears a hurdle is 2/3. Find P(clears all hurdles).

Gnom [1K]

Answer:

1024/59049

Step-by-step explanation:

P( clear hurdle) = 2/3

There are 10 hurdles

P ( clear all hurdles) = P( clear hurdle) * P( clear hurdle)...... 10 times

= 2/3 * 2/3 *....... 10 times

= (2/3) ^ 10

=1024/59049
