220ft squared
To find the area, you find the area of the 3 main figures, the triangle on the right, the square on the top left, and the rectangle left on the bottom and add all the areas up. If you do not know how to do this, please comment and I will guide you. :)
By definition, rational numbers are numbers that ca be expressed as a fraction that either terminates when divided or repeats when divided. Integers, on the other hand CANNOT be fractions, so integers are more specific than rational numbers. So the first statement above is not true. I just stated that repeating decimals are rational, so the second statement is not true either. When you divide 715 by -14 you get a number that appears to not terminate or repeat, so the third statement down is true. Terminating decimals are rational, so the fourth statement down is true. As for the last one, I am assuming that the ..... you have after that number means it goes on and on and since it doesn't repeat within those numbers you've listed there I'm assuming that it doesn't repeat or terminate so it is not a rational number. The only 2 statements that are true (or "apply", according to your instructions) are the third and the fourth statements down.
Answer:
20cm
Step-by-step explanation:
2 = 30
30 (10) = 2(10)
A.) 75 x 60 = 4500 in an hour
4500 x 24 = 108000 in a day
108000 x 365 = 39420000 in a year
39420000 x 45 = <span>1,773,900,000 in 45 years
</span>B.)2200800 / 75 = 29344 mins
29344 / 60 = <span>489.066666667 hours
</span>489.066666667 / 24 = 20.37777778
you get it
4: (3/4 - 1/2) X 3/5.
You need them all to have the same denominator (bottom number)
The lowest common denominator (LCM) of 2,4 and 5 is 20
4 X 5 = 20
2 X 10 = 20
5 X 4 = 20
Then multiply the top number by the amount you need to multiply the bottom number by to get 20
3 X 5 = 15
1 X 10 = 10
3 X 4 = 12
(3/4 - 1/2) X 3/5. Turns to (15/20 - 10/20) X 12/20.
15 - 10 = 5
5 X 12 = 60
Answer: 60/20
Simplified: Either 3 or 3/1.
If you use the steps above then you should be able to do the rest :D
