It was a good weekend for OnePlus 5T rumors — it looks likely the 5T will be first appearing in New York, and we got a spec leak that supports the rumors we've already heard. However, perhaps the best 5T news came from OnePlus' CEO himself: The OnePlus 5T may cost $600 or less.
This tutorial is about using logical comparisons in a sentence. We should compare only equivalent concepts. Don't compare something to a group its part of without including 'other' or 'else'. Be clear about what you are comparing. The comparisons must be between apples to apples (i.e. between objects or things of same group). If they are not then you fix the problem by:-1. Repeating the apples. 2. Using 's or that or those. 3. Reworking the sentence. To demonstrate this take the following exa...
This video tells us the method of interpreting derivatives of marginal cost and revenue. If C(x) is the cost of producing x units of a product, C(400) would be the cost to produce 400 units. Now marginal cost is the cost of producing one unit which is equal to the derivative of the cost function or C'(400) which is equal to limit of h tends to zero or lim h->0 [lim(400+h)-lim(400)]/h which is approximately equal to [lim(401)-lim(400)]/1. Similarly, if R(x) is your revenue function, marginal r...

If you have a receipt where you see how much you paid and know the tax rate, except you want to figure out the cost of the item before the tax. First, take the cost of the item including tax and what the tax rate is. To figure out the original price, let x equal the cost of the item. Add the tax to the cost of the item which will equal the cost you paid. Perform the equation 1x+(tax rate)= (total price). After you figure this equ...

A short video teaching you how to compare fractions. Starting with two fraction like three fourths and two over twelve. You cross multiply the denominator or the bottom number of three fourths which is 4 with the numerator or the top number of the second fraction which is 2. So the 8 that you come up with goes under the two twelfths. Now you do the same for the two fraction this time multiplying the denominator 12 with the numerator 3 coming up with 36. So now you have 36 under three fourths ...
