1/10 of 0.9= 0.09
8*10= 80
Are you trying to get the answer 80.09
Even though it's 2 <em>cubic</em> feet, it doesn't matter. It still can be transformed into inches.
1 foot = 12 inches
Multiply the 2 feet by 12 which should be:
12×2=24
So 24 cubic inches can be fit into a empty box with a volume of 2 cubic feet.
Hope this helps!
Example of a real world problem:
Chris is starting a handmade card business. In the beginning, he starts off with 15 cards and makes 4 new cards every week.
The variable (x) would represent the number of weeks that passed.
Example 2:
Sam decides to start saving up money to buy a video game. She starts off with 15 dollars and gets an allowance of 4 dollars every day.
The variable (x) would represent the number of days that pass.
To come up with your own equation, most times, x represents a unit of time. The zero value (the number that isn’t being multiplied by a variable) in the equation always represents your starting value, and the coefficient of the variable represents how much of something is being gained or added after a duration of time.
I hope this helps!
3 2/3 - 1/2
= 11/3 - 1/2
= 22/6 - 3/6
= 19/6
= 3.1666666667
Answer:
Perimeter of triangle CDE = 56
Step-by-step explanation:
Here, we want to find the perimeter of CDE
mathematically, when the measure of the inner triangle is half of the respective sides of the bigger
What this mean is that for each side that one of the side of the inner triangle faces, the measure on the bigger triangle is twice
Thus, 9 represents a length of 2(9) = 18 on the bigger triangle
Also, 7 will represent a length of 2(7) = 14 on the bigger triangle
So, now we have the complete sides of the bigger triangle
The measure of the perimeter is simply the addition of the respective side lengths
We have the perimeter of the large triangle as;
24 + 18 + 14 = 56
