Is this your ans of question
160,000 because you need to first multiply 800 by 12 since it is from a year (annum) to months you should get 9,600 then rather than multiplying by 0.06 to find 6% we divide to find what it is 6% of.
A perfect square is a number that can be expressed as the product of two equal integers. To determine that a trinomial is a perfect square we use the the discriminant given by:
b^2-4ac
where a,b and c have been obtained from the trinomial given by:
ax^2+bx+c;
if the value of the discriminant is a perfect square then the trinomial is a perfect square trinomial
-1.25 gallon is the change of the amount of water after 1/3 of an hour.
You just need to times -3.75 by 1/3 and you will get the answer of 1/3 hour
Answer:
240
Step-by-step explanation:
Since David has 60 fewer storybooks than Huiling, take the total number of storybooks, which is 460 and minus it by 60.
460-60=400
Now, there are 5 units, 5units=400
1unit=80
Since Jenny has 3 times as many storybooks as David, Jenny has 3 units, 3unit=80x3=240
