Rational expressions are often used in combining rates of work. Therefore, it's true.
<h3>What is rational expression?</h3>
It should be noted that a rational expression is simply defined by a rational fraction.
They're are used in combining rates of work. Fir example, if Mr John performs 1/2 of his work and does 1/3 on another day. This can be expressed as:
= 1/2 + 1/3
= 5/6

Answer:
1.The sum of thrice a certain number and six is greater than twenty seven.
2. Three times a certain number added to six the result is greater than twenty seven.
Step-by-step explanation:
The inequality whose word problem to be written is 3x + 6 > 27
Let x be a certain number.
So, we can write the following as the word problem of the inequality :
1.The sum of thrice a certain number and six is greater than twenty seven.
2. Three times a certain number added to six the result is greater than twenty seven.
Answer:
OG = 8.7
Step-by-step explanation:
The angle a tangent makes with a radius at the point of tangency is a right angle. That means ΔOGH is a right triangle.
The tangents to a circle from an external point are congruent, so GH = GI = 6.3. Now we know the sides of the right triangle are of lengths 6 and 6.3. The hypotenuse, OG is found using the Pythagorean theorem.
OG² = OH² +GH²
OG² = 6² +6.3² = 75.69
OG = √75.69 = 8.7
The length of OG is 8.7 units.
