Answer:
|x − 0.5| = 0.05
Step-by-step explanation:
Here x represents the diameter,
Since, an error of 0.05 millimeters is allowance in diameter,
Thus, the maximum acceptable diameter = x + 0.05,
And, the minimum acceptable diameter = x - 0.05
According to the question,
The holes will have a diameter of 0.5 millimeters,
Thus, x - 0.05 < 0.5 and 0.5 < x + 0.05
⇒ x - 0.5 < 0.05 and x - 0.5 > - 0.05
⇒ x - 0.5 < 0.05 and -(x -0.5) < 0.05
⇒ |x-0.5| < 0.05
⇒ Option D is correct.
Answer:
t=v-u/a
Step-by-step explanation:
t= v-u/a
we must move u to the other side and divide over a
Answer:
-6 +2 = -4
Step-by-step explanation:
Its simple. Whenever you see two negative signs next to each other, they merge into an addition sign "positive".
-6+2 = -4

<em><u>Solution:</u></em>
Given that we have to find the sum of 
<em><u>Let us first convert the mixed fractions to improper fractions</u></em>
Multiply the whole number part by the fraction's denominator.
Add that to the numerator.
Then write the result on top of the denominator
Therefore,

Now we can add both the fractions

Make the denominators same

Now convert the fraction to mixed number
When we divide 53 by 10 , the remainder is 3
Therefore, write 5 as a whole number and and 3 as numerator and 10 as denominator

Thus the sum of given mixed fraction is
