What's a simple method to find the cube root of a number ?

1 answer:

6 0

If you want to find out ..for example.. cube root of 8..just put it in the calculator!
Or you could power it by 1/3 ...which is the same thing as cube rooting it.
(Even though I need the calculator in both the cases..)

Hope this helps though :)

Max has a drawer full of green and red socks. He has three times times as many red socks subtracted from four times as many gree

monitta

Answer:

There are 42 red colour socks and 44 green color socks

Step-by-step explanation:

Let there are r red socks and g green socks.

ATQ,

He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks.

4g-3r=50 ....(1)

Half the number of green socks plus one-third of the number of red socks is 36.

$\dfrac{g}{2}+\dfrac{r}{3}=36\\\\3g+2r=216\ .....(2)$

Multiply equation (1) by 2 and equation (2) by 3.

8g-6r = 100 ....(3)

9g +6r = 648 ....(4)

Add equation (3) and (4)

8g-6r + 9g +6r = 100+648

17g = 748

g = 44

Put the value of g in equation (1).

4(44)-3r=50

176-3r = 50

176-50 = 3r

r = 42

Hence, there are 42 red colour socks and 44 green color socks.

A type of bamboo holds The Guinness world record for fastest growing plant. It can grow up to 91 cm per day. How fast in inches

Readme [11.4K]

Hey there! This problem seems tricky, but once we figure out how to solve, it becomes much more simple.

It looks like we have two conversions here:

Centimeters to Inches

Days to Hours

To convert them, we need to know their conversion rate, or in other words, how many centimeters are in an inch and how many hours are in a day.

2.54 cm. = 1 in.

1 day = 24 hours

Now that we have these in mind, all we need to do is a bit of division.

We will start with the expression "91 ÷ 24." This will break up our 91 centimeters into 24 hours, giving us the number of centimeters per hour. We use the "curvy equal sign" to show an approximate value.

91 ÷ 24 ≈ 3.7917

But wait! We aren't quite done yet. That expression only represents the number of centimeters per hour. Our question asks us for the inches per hour. Therefore, we need to do another expression.

If we use the expression "3.7917 ÷ 2.54," we will almost get an exact value. Keep in mind that the "2.54" represents how many centimeters are in an inch. Again, the "curvy equal sign" represents an approximate value.

3.7917 ÷ 2.54 ≈ 1.49

Using the logic above, we can say that the bamboo grows about 1.49 inches per hour.
