Answer:
The surface area of the drum is 3317.5218 square inches.
Step-by-step explanation:
Drum's have a cylindrical form, therefore in order to calculate its surface area we need to apply the correct formula, as shown below:
Where the first term of the sum is the area of the lid and bottom of the drum and the second term is the area of the walls of the drum, r is the radius and h is the height. Applying the data from the problem, we have:
The surface area of the drum is 3317.5218 square inches.
Pour 4 times of 124-gallon into a big jug.
Amount of water = 124 x 4 = 496 gallons
Then use the 45-gallon jug to scoop out the water 11 times.
Amount of water scooped out = 11 x 45 = 455 gallons
Water remaining = 496 - 450 = 1 gallon.
Answer:
0.927
Step-by-step explanation:
just plug it in to a algebraric calculator!
Distributive property was the first property used in STEP 1, where -4 was distributed to -3x+ 2 resulting in the equation in STEP 1. Next in STEP 2, commutative property of addition no matter how 12x and 6x are arranged, when you add them together the result will be the same.
*Take note that 12x and 6x are put together because they are like terms.
For Steps 3 and 4, you will see that the addition property of equality was used in STEP 3. To keep the equation equal, you will add the same number on both sides.
STEP 4 uses Division property of Equality. Like Step 3, to keep both sides of the equation equal, you must divide both sides with the same number. It keeps the statement true by doing so.
STEP 4 and 5 uses transitive property if you examine both as a whole.
Transitive property assumes that if a = b and b = c, then a = c
If 18/18 (a) = 1 (b), and x (c) = 18/18(a) then, x (c) = 1 (b).
Equations can be solved in several ways; one of these ways is the graphical method.
The number of commercials, x, and the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.
Let:
<em />
<em> commercials</em>
<em />
<em> movies</em>
<em />
She earned a total of $300.
This is represented as:
Her songs were played on 3 more commercials than movies.
This is represented as:
See attachment for the graphs of
From the graph, the lines of both equations intersect at:
This means that:
- <em>The number of movies is 2</em>
- <em>The number of commercials is 5</em>
