OK so it is not as hard as it seems if you add all the angles inside of one triangleit will always be 180 if you did it right and if you and 2 conecting triangs side by side if they are a stright line you would also get 180 ..and if it is not a triangle and it is some type of quadralateral, meaning a shape with 4 sides, you should always add up to 360

For example where you got 50 degrees all you had to do was add up your givin angles and subtract it by 180 since it is a triangle and that would give you 50 if you have any more questions on this just ask

An airline runs a commuter flight between Portland, Oregon, and Seattle, Washington, which are 145 miles apart. An increase of 2

pychu [463]

The speed of the airplane is the ratio of the distance to the time

The initial average speed of the airplane is approximately 110.8 mph

Reason:

Given parameters are;

The distance between Portland Oregon and Seattle Washington = 145 miles

The decrease in travel time when the speed is increase by 20 mph = minutes

The initial speed of the airplane, v = Required;

Solution;

$t = \dfrac{145}{v}$

$t - \dfrac{12}{60} = \dfrac{145}{v + 20}$

Therefore;

$\dfrac{145}{v} - \dfrac{12}{60} = \dfrac{145}{v + 20}$

Which gives;

$\dfrac{145}{v + 20} - \dfrac{145}{v} + \dfrac{12}{60} = 0$

Therefore

0.2·v² + 4·v - 2,900 = 0

v ≈ ±110.8 mph

The initial average speed of the airplane, v≈ ± 110.8 mph

nydimaria [60]

Answer:

$2.58\ more\ nuts\ Miguel\ uses\ than\ raisins.$

Step-by-step explanation:

$Nuts\ used=5\frac{1}{3}\\\\Nuts\ used=\frac{16}{3}$

$Raisins\ used=2\frac{3}{4}\\\\Raisins\ used=\frac{11}{4}$

$difference\ between\ nuts\ and\ raisin=\frac{16}{3}-\frac{11}{4}=\frac{64-33}{12}=\frac{31}{12}\approx 2.58$

$2.58\ more\ nuts\ Miguel\ uses\ than\ raisins.$

jane hilman went to her bank. she has a balance of $1009.88 in her savings account. she withdrew $130.00 and the teller credited

blagie [28]

First substract $130.00 from $1009.88 like this:
$\$1009.88-\$130.00=\$879,88$
Then substract $6.19 we get:
$\$879,88-\$6.19=\$873,69$
$873.69 is the remaining amount in Jane hitman's account.
