The square root of a number "n" is a number that when mutiplied by itself returns "n'
The cube root of number "n" is a number that when multiplied together three times equals "n"
Example
√64 = 8 because 8*8 = 64
3√64 = 4 because 4*4*4 = 64
Answer x < -6.
So to solve for x, get it down to its lowest terms we have to isolate x.
We first want to do that by getting rid of the dividing 3 over x. We can do that by multiplying 1/3 by 3, it’s reciprocal…and what we do to one side we have to do to another. So we will also multiply the -2 on the other side by 3. (Which is -6) This will cancel it out and leave us with our final answer…
x < -6
Answer:
48%
Step-by-step explanation:
I like to look at percentages as test grades. If you got a 130/250 on a test, you would simply need to view the dash line as a 'divided by'. So you would figure 130 divided by 250 is .52, or 52%... Then, you would need to subtract 52 from 100 to get 48% to get the percentage of people who do not walk to school.
Answer:
8 months
Step-by-step explanation:
The question asks for the minimum number of months it would take her to grow her hair ATLEAST 16 cm.
Lets solve this!
Her hair is ALREADY 4 cm
She needs to make it 16 cm or greater
That is:
16 - 4 = 12 cm MORE
Per month growth rate = 1.5 cm
So we will divide the amount she needs to grow (atleast) by the growth rate per month:
12/1.5
= 8
Thus, in 8 months, her hair will grow:
8 * 1.5 = 12 cm
and 4 cm from before, so
12 + 4 = 16 cm
So, it will take a minimum of 8 months
