the answer is 2 1/2
Step-by-step explanation:
You just double 1/2 and that gets you 2/2 which equals 1 whole. So since you multiplied 1/2 by 2 you do the same to the 1 1/4 (1 1/4 times 2 = 2 1/2)
Answer:
3/5
Step-by-step explanation:
You can divide 18 by 6 to get 3, and since you need to dive the same number by the top and bottom, 30 divided by 6 is 5.
Answer:
39.25 cubic feet of paint will be needed by Ellis.
Step-by-step explanation:
Volume of a cylinder:
The volume of a cylinder of radius r and height h is given by:
How much paint will Ellis need to paint all the surfaces of the 10 fenceposts?
This is the combined volume of these 10 fenceposts.
They are each 5 feet tall and have a diameter of 1 foot.
Radius is half the diameter, so . Also
10 fenceposts:
Each has the same volume, so:
39.25 cubic feet of paint will be needed by Ellis.
Answer:
B
Step-by-step explanation: If you put 7 2/5 - 5/8 in a calculator it comes to equal 6.775. Since the answer is asking for an estimate then the answer would be 7.
<span>The fundamental idea of
multiplying is <em>repeated addition</em>. For example:
By taking the number five and add it itself three times we have:
In contrast, let's take the number
three and add it itself five times, so:
.
Both 3 and 5 are called
factors that are numbers. We can multiply them to get another number. Multiplying can also be expressed like this:
So you have the factors:
You can even write any multiplication as the
product of factors. On the other hands, factoring shows that you can write any nth-degree polynomial as the product of linear factors, so:
To conclude the <em>relationship</em> between both concepts is the
product of factors.</span>
