Answer:
y = 300
Step-by-step explanation:
The equation of variation in which y varies directly as x is written Mathematically as:
y ∝ x
y = k × x
y = kx
Where k = Proportionality Constant
We find k
a) y = 60 when x = 0.4.
60 = 0.4 × k
k = 60/0.4
k = 150
b) find the value of y when x = 2
y = kx
k = 150
Hence,
y = 150 × 2
y = 300
Answer:

Step-by-step explanation:
Answer:
Here's a 2 step conversion.
Step-by-step explanation:
1. Convert the fraction to a decimal: Divide the numerator by the denominator
2. Add this decimal number to the whole number part of the mixed number
A mixed number is a whole number plus a fraction. To find the decimal form of a fraction just divide the numerator by the denominator using a calculator or long division. Then add the decimal number to the whole number.
Example: Convert the mixed number 7 1/4 to a decimal
Convert the fraction to a decimal: Divide 1 by 4
1 ÷ 4 = 0.25
Add 0.25 to the whole number 7:
7 + 0.25 = 7.25
<em><u>Question:</u></em>
Is square root of 1.6875 a rational number ?
<em><u>Answer:</u></em>
Square root of 1.6875 a rational number is not a rational number
<em><u>Solution:</u></em>
Given that we have to find square root of 1.6875 and determine if it is rational number or not
Let us first find square root of 1.6875

Let us understand about rational number
A rational number is a number that can be expressed as a fraction (ratio) in the form
where p and q are integers and q is not zero.
When a rational number fraction is divided to form a decimal value, it becomes a terminating or repeating decimal.
So the number 1.29903810568 is not a rational number
<em><u>In other words we can say,</u></em>
Only the square roots of square numbers are rational. Here 1.6875 is not a perfect square. So it is not rational number
