Unit rates, which are a ratio in which the denominator's unit is one, allow us to compare. To calculate unit rates, we simply divide the two numbers in the fraction. The resulting decimal form is the unit rate. Unit prices are a special type of unit rate comparing an item's cost per unit (e.g., $ / pound).

Please help fast! C=?
Alisiya [41]

Answer:

Step-by-step explanation:

By the law of Sines,

\frac{\sin 88^{\circ}}{26}=\frac{\sin C}{21}\\\sin C=\frac{21 \sin 88^{\circ}}{26}\\C=\sin^{-1} \left(\frac{21 \sin 88^{\circ}}{26} \right) \approx 54^{\circ}

However, it follows that C \approx 126^{\circ} must also be a solution.

Olivia walked 2 2/5 km in 2/3 hour while Ryan walked 4 1/2 km in 1 1/2 hours. Who walked faster and how much faster?
Aleks04 [339]
Find the unit rate for each Olivia and Ryan:

2 2/5 km       15       36 km
------------ * ------- = ------------ = 3.6 km/hr (Olivia)
 2/3 hr          15        10 hr


4 1/2 km          2          9 km
------------- * --------- = --------- = 3 km/hr (Ryan)
1 1/2 hr           2           3 hr

Olivia walked 0.6 km/hr faster than did Ryan.

1/4 * 8x = 2x

1/4 * 12 = 3

2x + 3 = 21

21 - 3 = 18
