a leatherback turtle swims at a constant rate of 2.5 kilometers per hour, at its constant rate of speed how long will it take fo

LekaFEV [45]

Hello there!

So, if this turtle is only going 2.5 miles per hour. This would mean that (EACH) hour, this turtle only arrived 2.5 miles. So, we do,

$\boxed{10.0 \left \{ {{2.5+2.5=5.0} \atop {2.5+2.5=5.0}} \right.}$

We would have to count how many ("2.5's" they are above.)

We count only 4.

I would take this turtle 4 miles to swim 10 kilometers.

How do I get the answer 1/2•-3 4/7

earnstyle [38]

First off, we need to convert the mixed fraction to "improper", and then just multiply linearly, let's do so,

$\bf \stackrel{mixed}{3\frac{4}{7}}\implies \cfrac{3\cdot 7+4}{7}\implies \stackrel{improper}{\cfrac{25}{7}}
\\\\\\
\cfrac{1}{2}\cdot \cfrac{25}{7}\implies \cfrac{1\cdot 25}{2\cdot 7}\implies \cfrac{25}{14}\implies 1\frac{11}{14}$

Estimated bill amount is $57

Step-by-step explanation:

Step 1:

Round off the cost of 1 appetizer.

Cost of 1 appetizer = $6.50 ≈ $7

Step 2:

Find the cost of 2 main courses.

Cost of 1 main course = $15.75 ≈ $16

∴ Cost of 2 main courses = 2 × 16 = $32

Step 3:

Find cost of 2 drinks.

Cost of 1 drink = $2.25 ≈ $2

∴ Cost of 2 drinks = 2 × 2 = $4

Step 4:

Find the cost of 2 desserts.

Cost of 1 dessert = $7.25 ≈ $7

∴ Cost of 2 desserts = 7 × 2 = $14

Step 5:

Add all and find the total cost.

Estimated Total bill amount = 7 + 32 + 4 + 14 = $57
