Answer:
No, I don't think so.
Step-by-step explanation:
If his suitcase weighs 23 kg and 10 kg is 22 pounds. You could seperate it. 10, 10, and 3 meaning 22+22= 44. This would mean that 1 kg would equal about 2.2 a pound. So 44 + ( 2.2 x 3 ) = 50.6 kg.
It would be 0.6 k.g over. I think this is right unless I calculated this wrong.
Answer:
9
Step-by-step explanation:
6n = n² - 27
n² - 6n - 27 = 0
n² - 9n + 3n - 27 = 0
n(n - 9) + 3(n - 9) = 0
(n - 9)(n + 3) = 0
n = -3, 9
Answer:
2 1/2 = 5/2
Step-by-step explanation:
There is a trick you can do when converting mixed numbers into improper fractions
Multiply the whole number and denominator, in this case you'll do 2 * 2 which equals 4
Finally, add the numberator to your product. For this you'll do 4 + 1 which equals 5
When done, keep the denominator and keep your sum as the numerator. 5/2!
Answer:
Change = -(1/2) * 30 = -15 inches
Step-by-step explanation:
If the water level decreases by 1/2 inch each day, the change in the water level in one day is -1/2 inch.
So, after t days, the total change in the water level can be calculated as:
Total change = -(1/2) * t inches
So, after 30 summer days, the total change is:
Change = -(1/2) * 30 = -15 inches
So the water level of the pool after 30 summer days has decreased by 15 inches.
Answer:
The number of terms of the G.P. is 6
Step-by-step explanation:
Let the G.P. has first term a, common ratio r and the number of terms n.
The G.P. has first term 2, so a = 2.
Now, the fourth term is 54 i.e. ar³ = 54
⇒ 2r³ = 54
⇒ r³ = 27
⇒ r = 3
Now, the last term i.e. the nth term is= 
⇒ 
⇒ 
Hence, (n - 1) = 5
⇒ n = 6
So the number of terms of the G.P. is 6 (Answer)
