N=9
Since you are multiplying on the right side you have to divide when you bring 0.5 to the left side:
4.5 divided by 0.5 = n
9 = n
1) The answer for both includes a circle. You would rotate the shape around the axis of symmetry, creating an infinite number of 2-d circles stacked on top of each other, creating the cone or cylinder. In the case of a cylinder, the other shape is a rectangle, and in the case of a cone, a right triangle with one line serving as the axis of symmetry.
2) The volume of a cone is the area of the base, multiplied by height, divided by 3. This means that the volume of a cone is 1/3 the volume of a cylinder of equal height and base area. The volume of a cylinder is the area of the base times height. The volume of a pyramid, similar to a cone, is the area of the base (length x width) times the height, divided by three.
3) One definition of density is mass/volume, or mass per unit of volume. For example, if a 5 kg object has a volume of 10 cm³, than the density would be 0.5kg/cm³. In population density, relative to our example, area takes the place of volume and population takes the place of mass. This means that population density is population/area. For example, if 10,000 people occupy an area of 5 square miles, then the population density is 2,000 people/ square mile.
4) As you are clearly learning in this class, the volume of an object is not only determined by its dimensions, such as base, width, and height, but its shape. Let's review the cone example. If a cone and a cylinder have the same base area and height, the cone has a volume of 1/3 that of the cylinder.
5) When might you want to use volume in your daily life? Here is a depressing example. Say your corporate job in the Accounting Department has you feeling blue, and your only break is your daily trip to the water cooler. The cups at the cooler are cone-shaped. Not only is this inconvenient because you can't stand them up without getting the rim dirty, but these cups contain 1/3 the water that a perfectly cylindrical cup of the same base/height could provide. You may tell your manager this, and earn yourself some fancy new cylindrical paper cups!
<em>7 grams of sugar</em>
<h2>
Explanation:</h2>
________________________________________
I'll assume your answer is as follows:
<em>A bowl of cereal had 3 3/6 grams of sugar in it. If Victor ate 2 bowl a week, how many grams of sugar would he have eaten?</em>
________________________________________
If so, then we know that:
- A bowl of cereal had 3 3/6 grams of sugar in it.
In other words, the total of sugar he ate can be calculated as:

So <em>he'd have eaten 7 grams of sugar</em>

Answer:
ratio of pure lemon juice to water in the homestyle lemon drink is 5 : 19.
Step-by-step explanation:
In order to solve the final ratio of lemon juice to water, let us start by determining the initial ratio of pure lemon juice to water in the first mix. This is done as follows:
Total volume of mixture = 60 liters
initial volume of water = 60 liters
initial volume of lemon juice = 0 liters
1) She removed 15 liters of the water and replaced it with 15 liters of pure lemon juice.
Volume of water = 60 - 15 = 45 liters
Volume of lemon juice = 15 liters

2) She removed 10 liters of the new mixture
Let us convert this amount removed into ratio:

New volumes of water and lemon juice after removing the 10 liters of mixture is calculated as follows:

3) and replaced it with 10 liters of water.

The final ratio of lemon juice to water:

Therefore, the final ratio of pure lemon juice to water in the homestyle lemon drink is 5 : 19.
Step-by-step explanation:
this is quite easy, when you use just common sense and identify the right numbers and variable names.
they is nothing special needed, you don't even need to create the equations yourself.
$4.99 per pound. buys b pounds and pays $14.95.
14.95 = 4.99 × b
$4.99 per pound. buys b pounds and pays c.
this is exactly the same as before, just that this time the total amount is not given as a constant but as a variable.
c = 4.99 × b
d dollars per pound. buys b pounds and pays t.
the same as the 2 cases before, just now everything is a variable. no more constants, but otherwise the completely same structure and method.
t = d × b
earned $275, which is $45 more than Noah ("n").
$275 = n + $45
earned m dollars, which is $45 more than Noah ("n").
m = n + $45
earned m dollars, which is y dollars more than Noah (we are asked that Noah's earnings are now called "v").
here your teacher made a mistake.
sure, the only remaining answer is
v = m + y
but it is not correct. given the names of the prime and associated variables the correct answer would be
m = v + y or v = m - y
