A rational number would be 81/10 or 8.1
Answer:
the answer is 32cm squared
Step-by-step explanation:
Answer:
The two numbers are 52 and 12.
Step-by-step explanation:
x+y=64
x=16+3y
Now, substitute the second equation into the first one.
16+3y+y=64
16+4y=64
4y=48
y=12
Substitute 12 into one of the equations in order to find x.
x=16+3(12)
x=16+36
x=52
<h2>
The product of two numbers is <em>
a,</em>
of both numbers.</h2>
Step-by-step explanation:
Given,
The product of two numbers = a
To find, the both numbers = ?
Let the two numbers = x
∴ x × x = a
⇒ 
= a
⇒ 
Comparing the powers, we get
⇒ x =
∴ First number = and Second number =
Thus, the product of two numbers is <em>a,</em> of both numbers.
Answer:
2.899
Step-by-step explanation:
The formula for calculating the distance between two points P(x1, y1) and (x2, y2) is expressed as:
D = √(x2-x1)²+(y2-y1)²
Given the points (2,-2) and (1,x) and the distance between the point as 5, we are to get x. To get x we will substitute the points and the distance given into the formula.
Given x1 = 2, y1 = -2, x2 = 1, y2 = x and D = 5
On substitution:
5 = √(1-2)²+(x-(-2))²
5 = √1²+(x+2)²
5 = √1+(x+2)²
Square both sides of the equation
5² = (√1+(x+2)²)²
25 = 1+(x+2)²
(x+2)² = 25-1
(x+2)² = 24
Square both sides
√(x+2)² = √24
x+2 = √24
x = √24- 2
x = 4.899-2
x = 2.899
Hence the other value is 2.899
