An 1 1/2 minus 1/4 is equal to 1 1/4 or 1.25 as a decimal.
To subtract fractions, they must have a common denominator the common denominator is 4. Let's find the equivalent fractions with a denominator of 4:
1 1/2 is the same as 1 + 1/2, and convert 1/2 to have a denominator of 4:
1 + 1/2 = 1 + 2/4
Now, subtract 1/4:
(1 + 2/4) - 1/4 = 1 + (2/4 - 1/4) = 1 + 1/4

Answer with Step-by-step explanation:
Let the ones digit of the number be y
and tens digit of the number be x.
The tens digit is two less than the units digit.
i.e. x=y-2
The value of the number exceeds twice the sum of its digits by 19.
i.e. 10x+y=2(x+y)+19
10(y-2)+y=2(y-2+y)+19
10y-20+y=2(2y-2)+19
11y-20=4y-4+19
11y-4y=20-4+19
7y=35
dividing both sides by 7, we get
y=5
Putting value of y in x=y-2, we get
x=3
10x+y=10×3+5
=35
Hence, the two digit number is:
35

Step-by-step explanation:
r = 4.9 miles
Area of circle = πr²
= 3.14 * 4.9 * 4.9
= 75.39 square miles
The given expression -8 ÷ 343 can situationaly be written in power notation as -8 ÷ 7^3. This transformation changes '343' to '7^3' since 343 is 7 cubed.
The expression -8 ÷ 343 cannot be directly written in 'power notation', as the concept of'power notation' commonly refers to writing an expression in the form of a base value raised to an exponent.
Power notation is typically represented as a^n, where 'a' is the base and 'n' is the exponent. However, '343' can be written in power notation since it is 7 cubed (7^3).
So, while we should clarify the details, one way to write the expression could be -8 ÷ 7^3.
