Answer: ![7\times10^{19} buckets](https://tex.z-dn.net/?f=7%5Ctimes10%5E%7B19%7D%20buckets)
Step-by-step explanation:
Given: A cubic kilometer=
cubic centimeters
The volume of world’s oceans=
cubic kilometers of water.
⇒ The volume of world’s oceans=
cubic centimeters of water.
Volume of a bucket = 20,000 cubic centimeters of water.
The number of bucket-loads would it take to bucket out the world’s oceans
![n=\frac{\text{volume of ocean}}{\text{volume of bucket}}=\frac{1.4\times10^{9}\times10^{15}}{20000}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B%5Ctext%7Bvolume%20of%20ocean%7D%7D%7B%5Ctext%7Bvolume%20of%20bucket%7D%7D%3D%5Cfrac%7B1.4%5Ctimes10%5E%7B9%7D%5Ctimes10%5E%7B15%7D%7D%7B20000%7D)
![\Rightarrow\ n=\frac{1.4\times10^{9+15}}{0.2\times10^5}......[a^n\times a^m=a^{m+n}]\\\Rightarrow\ n=7\times10^{24-5}.....[\frac{a^m}{a^n}=a^{m-n}]\\\Rightyarrow\ n=7\times10^{19}](https://tex.z-dn.net/?f=%5CRightarrow%5C%20n%3D%5Cfrac%7B1.4%5Ctimes10%5E%7B9%2B15%7D%7D%7B0.2%5Ctimes10%5E5%7D......%5Ba%5En%5Ctimes%20a%5Em%3Da%5E%7Bm%2Bn%7D%5D%5C%5C%5CRightarrow%5C%20n%3D7%5Ctimes10%5E%7B24-5%7D.....%5B%5Cfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5D%5C%5C%5CRightyarrow%5C%20n%3D7%5Ctimes10%5E%7B19%7D)
hence,
bucketloads would it take to bucket out the world’s oceans.
Answer:
y = x - 7
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
The First section of the equation (2-2) cancel each other out and you are left with 5x=5x
Answer:
C
Step-by-step explanation:
so taking the slope from the points (0,1) and (2,2)
we get slope= 2-1/2-0=1/2 the y intercept is one
so y=mx+b(where m is the slope and b is the y intercept)
we get= y=1/2x+1
which is C

Answer:
95999.99924
Step-by-step explanation:
9.6 × 10^4 = 9.6 × 10,000 = 96000
7.6 × 10^-4 = 7.6 × 0.0001 = 0.00076
96000 - 0.00076 = 95999.99924
