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)

Solve the inequality and explain the stores for the two questions below:
Taya2010 [7]

Answer:

a < 3

n < 3

Step-by-step explanation:

We will solve each inequality one by one.

Solve first inequality :

3a - 4 < 5

add 4 both the side

3a < 9

divide 3 both the side

a < 3

Solve second inequality:

\frac{n}{-3} + 5 > 4

subtract 5 both the side

\frac{n}{-3} > -1

now multiply by -3 both the side and reverse the inequality sign

n < (-3)*(-1)

n < 3


That's the final answer. I hope it will help you.

ich expressions are equivalent? Select Equivalent or Not equivalent for each pair of expressions. Equivalent Not equivalent 3(a+
kodGreya [7K]

3(a + b) and 3a + b - NOT EQUIVALENT because

3(a + b) = 3a + 3b

<em>used distributive property a(b + c) = ab + ac</em>

4(x + 2y) and 8y + 4x - EQUIVALENT because

4(x + 2y) = (4)(x) + (4)(2y) = 4x + 8y = 8y + 4x

<em>used distributive property a(b + c) = ab + ac</em>

<em>and commutative property a + b = b + a</em>
