Ben drinks tea at an incredible rate.He drinks 3 1/2 liters of tea every 2/3 of an hour.Ben drinks tea at a constant rate. How m

k0ka [10]

2/3 = 0.66

1 hour = 60

60 x 0.66 = 39.6 or 40

60 - 40 = 20

He would drink 3 1/2 liters every 30 minutes.

He drinks 3 1/2 every hour.

Can someone solve with working/solution these 3 questions Plzzz

Arada [10]

Answer:

(c) $x=55$ °

(d) $x=21$ °

(e) $x$ ° $=42$ ° and $y$ ° $=16$ °

Step-by-step explanation:

The triangle is an isosceles triangle with the base angles which are identical. The double stroke on the sides of the triangle indicates which angles are the base angle. The angle corresponding to the side of the triangle with no double stroke is known as the vertex angle.

(c) The given angle is the vertex angle in this question and it is 70°

Since, $x$ ° is one of the base angle, then the other angle which is not drawn is identical to $x$ ° .

Total angle of a triangle is 180°.

$180$ ° $-70$ ° $=2x$ °

$2x$ ° $=110$ °

Divide by 2 on both sides to get $x$ °

$x$ ° $=55$ °

(d)

The given angle is a base angle in this question and it is 63°.

Since base angles are identical, then

$63$ ° $=3x$ °

Divide by 3 on both sides to get $x$ °

$x$ ° $=21$ °

(e)

The given angle 48° is a base angle.

Since base angles are identical, then

$48$ ° $=3y$ °

Divide by 3 on both sides to get $y$ °

$y$ ° $=16$ °

Total angle of a triangle is 180°.

So, $180$ ° $-48$ ° $-3y$ ° $=2x$ °

$2x$ ° $=84$ °

Divide by 2 on both sides to get $x$ °

$x$ ° $=42$ °

Write -6 - 8i in polar form Appreciate any help thank you so much!

Temka [501]

-6 = r cos α and -8 = r sin α

r = sqrt( 6^2 + 8^2) = sqrt 100 = 10

α = arctan ( -8/-6) = arctan (4/3) = 53.13 degrees

polar firm = r ( cos α + i sin α)
= 10(cos 53.18 + i sin 53.18)

its been a long time but ui think thats correct

Show 2 irrational numbers equals an irrational number

victus00 [196]

Answer:

The sum of two irrational numbers, in some cases, will be irrational. However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational.
