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)

C and D are complementary. The measure of C is (4x) degrees and the measure of K is 26 degrees. What is the value of x?
Semmy [17]

Answer:

16

Step-by-step explanation:

Complementary angles are angles which add to 90 degrees. This means 4x + 26 = 90. Solve for x using inverse operations in the equation.

4x+26 = 90

4x = 64

x = 16
