Answer:

80°

Step-by-step explanation:

The sum of the interior angles in a hexagon is 720°. This means that:

y + (2y - 20) + (2y - 20) + y + (2y - 20) + (2y - 20) = 720° - we can simplify this

10y - 80 = 720° - now, add 80 to both sides

10y = 800 - finally, divide both sides by 10

y = 800 ÷ 8 = 80°

Hope this helps!

Yuki bought a pound of confetti for \$12$12. What is the price, in dollars, per ounce of confetti? There are 1616 ounces in 11 p

tatiyna

Answer:

$0.75

Step-by-step explanation:

We have been given that Yuki bought a pound of confetti for $12.

To find the price of per ounce of confetti, we will divide the total price of 1 pound confetti by number of ounces in 1 pound.

1 pound = 16 ounces.

Let us divide 12 by 16 to find the price of confetti per ounce.

$\text{Price of per ounce confetti}=\frac{12}{16}$

$\text{Price of per ounce confetti}=\frac{3}{4}$

$\text{Price of per ounce confetti}=0.75$

Therefore, the price of per ounce confetti is $0.75.

If a geometric sequence has a2 = 495 and a6 = 311, approximate the value of the common ratio ???? to four decimal

shtirl [24]

Answer:

$r = 0.8903$

Step-by-step explanation:

given,

a₂ = 495

a₆ = 311

geometric sequence formula

$a_n = ar^{n-1}$

$a_2 = ar^{2-1}$

$a_2 = ar$ ...................(1)

$a_6 = ar^{6-1}$

$a_6 = ar^5$ ................(2)

dividing equation (2) by (1)

$\dfrac{a_6}{a_2} = \dfrac{ar^5}{ar}$

$\dfrac{311}{495} = r^4$

$r^4 = 0.628$

$r = 0.8903$

hence, the common ratio of the geometric sequence is $r = 0.8903$
