A ghost crab can travel about 12 miles every 6 hours on the ocean’s floor. How far can the crab travel in 11 hours? Explain how
iren [92.7K]

Answer:

22 miles in 11 hours!

Step-by-step explanation:

We already know a ghost crab can travel 12 miles in 6 hours.

Now, we just need to find the how many miles per hour the crab walks.

We simply divide 12 miles by 6 hours which gives us 2 miles in 1 hour.

That means, we multiply 11 by 2 which gives us 22 miles!

The ghost crab can travel 22 miles in 11 hours. When you find the rate of change by dividing 12 by 6, it gives you 2 m/h. That enables you to find the amount of miles by multiplying 11 hours by two which gives you 22!

Help me to solve thisssss​
m_a_m_a [10]

Answer:

(a + 3)

Step-by-step explanation:

a³ - 9a = a(a² - 9) = a(a + 3)(a - 3)

a² + a - 6 = (a - 2)(a + 3)

a⁴ + 27a = a(a³ + 27) = a(a - 3)(a² + 6a + 9) = a(a - 3)(a + 3)(a + 3)

HCF = (a + 3)

Hope it helps.

A bracelet costs $39.59 including tax.It is marked down 25 percent.What is the final price of the bracelet after it is marked do
lara31 [8.8K]
If it is marked down 25% and 25% equals 25/100 then you simply take 39.59 x 25/100

39.59 x 25/100 = 9.90

and then you subtract that from the original price 

39.59 - 9.90 = $29.69

after it is marked down, the price is $29.69
