You have to convert the following number into a fraction:
This is a periodic decimal number, which explicitely is 0.68888888....
In order to convert this number to a fraction you proceed as follow:
You put 0.68 and not 0.688 because to do the convertion you need only the first periodic number (that is, only the first 8). The key is to put in the numerator the complete number as whole number, that is, 68. To this number you subtract the whole part of the decimal number, this whole part is 0 because of the 0.688. Then, in the numerator you have 68 - 0. In the denominator you write a number composed only by 9's. The number of 9 numbers is determined by the number of digits of the first number in the numerator. That is two 9 numbers
Answer:
the decimal is 0.49 ,you have to move two spaces to the right to get a decimal
Direct variation is of the form: y=kx (inverse variation is of the form y=k/x)
Assuming that k is positive :)
y increases as x increases and y decreases as x decreases. There is a direct ratio that is described by k. k=y/x.
Answer: what are the thing's you can choose
\Step-by-step explanation:
Given:
Diagonal measurement of a tv screen = 42 inches.
Base = 38 inches
To find:
The height of the tv.
Solution:
Let h be the length of the tv.
According to the Pythagoras theorem,
Taking square root on both sides.
Therefore, the height of the tv is inches.
