Diano4ka-milaya [45]
They earned 1800 in the five hours. First you need to multiply 12 by 10 and the 12 by 20 which will equal to 360 all together and then you need to multiply that by 5 which equals 1800.

What's the Constant of Proportianlity/Unit Rate?​
Leto [7]

Answer:

1/3 cup of juice per cup of berries

Step-by-step explanation:

The table shows that if we go from 0 to 4 cups (a "run" of 4 cups), the juice output is 1 1/3 (or 4/3) (a "rise" of 4/3 cups), and so the desired constant of proportionality is the unit rate

(4/3) cups

------------------------ = 1/3 cup of juice per cup of berries

A plane is flying at a heading of 125° at a speed of 320 mph. The wind is blowing from due North at a speed of 35 mph. Find the
ad-work [718]

Answer:

301.29\ \text{mph}

119.5^{\circ}

Step-by-step explanation:

v_p = Velocity of plane = 320 mph

v_w = Velocity of wind = 35 mph

\theta = Angle between wind and plane directions = 125^{\circ}

From triangle law we have resultant

v_r=\sqrt{v_p^2+v_w^2+2v_pv_w\cos\theta}\\\Rightarrow v_r=\sqrt{320^2+35^2+2\times 320\times 35\cos125^{\circ}}\\\Rightarrow v_r=301.29\ \text{mph}

Direction is given by

\phi=\tan^{-1}\dfrac{v_p\sin\theta}{v_w+v_p\cos\theta}\\\Rightarrow \phi=\tan^{-1}\dfrac{320\sin125^{\circ}}{35+320\cos125^{\circ}}\\\Rightarrow \phi=-60.46^{\circ}=180-60.46=119.5^{\circ}

The magnitude of the plane is 301.29\ \text{mph} moving at an angle of 119.5^{\circ}.
