A sea turtle swims at a speed of 27 kilometers per hour. A girl swims 14 decimeters per second. 1 m = 10 dm 1000 m = 1 km How mu
insens350 [35]
The sea turtle's speed is
v_{t} = (27 \, \frac{km}{h} )*(1000 \, \frac{m}{km} )*( \frac{1}{60} \, \frac{h}{min} ) = 450 \, \frac{m}{min}

The girl's speed is
v_{g} = (14 \, \frac{dm}{s} )*( \frac{1}{10} \, \frac{m}{dm} )*(60 \, \frac{s}{min} ) = 84 \, \frac{m}{min}

The ratio of the turtle's speed to that of the girl is
\frac{v_{t}}{v_{g}} = \frac{450}{84} =5.357

Answer: 5.36 faster  (nearest hundredth)

In DCAB, If DB=38, What is DC? 38 45 52 112
dedylja [7]

Answer:

C. 52°

Step-by-step explanation:

In ∆CAB, m<A = right angle = 90°

m<B = 38°

m<C + m<A + m<B = 180° (sum of ∆)

m<C + 90° + 38° = 180° (substitution)

m<C + 128 = 180

m<C = 180 - 128 (subtraction property of equality)

m<C = 52°
