Answer:
81
Step-by-step explanation:
Let the digits that make up the number be a and b.
Given that the square root of the number is equal to the sum of the digits.
Then,
√(10a + b) = a + b
Also given that the square root of the number is less than the number obtained by interchanging the digits by 9, then
√(10a +b) + 9 = 10b + a
Since √(10a + b) = a + b, then
a + b + 9 = 10b + a
a - a + 9 = 10b - b
9b = 9
b = 1
since √(10a + b) = a + b
√(10a + 1) = a + 1
10a + 1= (a + 1)²
10a + 1 = a² + 2a + 1
a² + 2a - 10a + 1 - 1 = 0
a² - 8a = 0
a(a - 8) = 0
a = 0 or a = 8
Using a = 8 and b = 1,
the number 10a + b = 10(8) + 1 = 81.
26% less = 74% of the original
In other word, $289 is 74% of the Original Price
629 = 74% * x
629 = .74*x
629/.74 = x
x = 850
Original price is $850

To answer this, first you must know the properties of a square.
With a square, each side is equal in length, which means:
4x- 50 = 60 cm
So now just solve it like a basic equation
Add 50 on both sides
4x - 50 = 60
+50 +50
4x= 110
Now divide both sides by 4
Answer is B. 27.5
Answer:
<em>10.</em>
Step-by-step explanation:
Lets define a <em>square root</em>. A square root is<em> a number multiplied by itself.</em> <em>10 x 10 = 100,</em> this is the <em>closest</em> we can get to <em>105</em>, therefore <em>10 is the answer.</em>
G+2h=7h+f (just reorganized the equation)
g= 5h+f
