If a varies inversely as the cube root of b and a=1 when b=64, find b​

Answer:

  b = 64/a³

Step-by-step explanation:

Using the given information, we can only find a relation between a and b. We cannot find any specific value for b.

Since a varies inversely as the cube root of b, we have ...

  a = k/∛b

Multiplying by ∛b lets us find the value of k:

  k = a·∛b = 1·∛64 = 4

Taking the cube of this equation gives ...

  64 = a³b

  b = 64/a³ . . . . . divide by a³

The value of b is ...

  b = 64/a³

Luke’s dad need 165 for a new suitcase. If he saves an equal amount for 3 weeks, how much does save each week?
goldenfox [79]
This is easy the answers 55 you just need to divide

165 ÷ 3 = ?

Step 1: Look at the multiplications of three can you make a group with an answer close to one? if not look at 16 and the multiplications of three is there a number close to 16 or exact?

Step 2: In this case 5 × 3 = 15, so 15 is close to 16.


Step 3: Now you need to subtract 16 and 15, 16 - 15 = 1.


Step 4: Like there's no number that has 1 as a answer, you need to lower the 5.


Step 5: Once you lower the five it makes 15 in the in the multiplications of three is there something close to 15 or exact? Yes there is a number that can make 15, it's 5 × 3 so 15 take away 15 makes zero so your answer will be simple, 55.

So Luke's dad needs to save $55 each week.

KATRIN_1 [288]

Answer:

1.79% chance or \frac{6}{343}

Step-by-step explanation:

7+3+4=14

chance of yellow \frac{3}{14}

chance of orange \frac{4}{14}

\frac{3}{14} * \frac{4}{14} *\frac{4}{14}  =  \frac{6}{343}

Mice21 [21]

Answer:

The first option     (5.7km)

Step-by-step explanation:

Since we have a right angle triangle and we know two of its sides we can easily find out the thirds side (the value of d) by using the Pathagoras Theorem. In our case 7 and d are our legs and the hypotenuse is equal to 9, so...

(Based on the Pathagoras Theorem)

c^{2} = a^{2}  + b^{2}

9^{2} = 7^{2} + d^{2}

d^{2} = 9^{2} - 7^{2} \\d^{2} = 81 - 49\\d^{2} = 32\\d = \sqrt{32}\\

d ≈ 5.7km

There for aproximate distance across the lake is equal to 5.7km
