Set up a fraction with 2 cups of sugar (s) at the top and 32 brownies (b) at the bottom. 2s/32b. Now, set up the next fraction with x cups of sugar (because we don't know the amount of sugar) at the top and 72 brownies (b) at the bottom. Set them equal. Your equation should be 2s/32b=x/72b. Cross multiply these values (if you wrote them down; 32x=144) and solve for x.

Step-by-step explanation:</h2>
If resistors are in series, so the current 
is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:
is the total resistance 
. Moreover:
Therefore:
Answer:
Step-by-step explanation:
The square root is possible only if y≤0
if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0
if y≤0 can be rewritten as:
3(-27x^2y^7)^1/2
or if we want simplify the expression:
^1/2
we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive
Answer:
$0.54
Step-by-step explanation:
Start by multiplying 4.5 times 1.20. That’s the normal price of the apples when they’re not on sale. $5.40. Move the decimal place back by one and you get 0.54. That’s the total price of the apples.
Answer:
There are about 3.281 * 3.281 = 10.764 square feet in one square meter. Therefore, 22.5 square feet is 22.5 / 10.764 = 2.09 square meters.
