Step-by-step explanation:

We have according to the options:

A. $\sqrt{100} \times \sqrt{100}=10\times 10=20$

B. $13.5+\sqrt{81} =13.5+9=22.5$

C. $\sqrt{9}+\sqrt{729}=3+27=30$

D. $\sqrt{64}+\sqrt{353}=8+\sqrt{353}$ , which is not rational.

E. $\frac{1}{3}+\sqrt{216}=0.3+6\sqrt{6}$ , which is not rational.

F. $\frac{3}{5}+2.5=0.6+2.5=3.1$

Hence, the expressions representing rational numbers are A, B, C and F.

A safety regulation states that the height hh of a guardrail should be 106 centimeters with an absolute deviation of no more tha

iren [92.7K]

Let us say that h is the height of the guardrail. Therefore the inequality equation that we can generate from this scenario is:

| h – 106 | = ± 7

There are two ways to solve this, either the equation is positive or negative.

When the equation is positive, therefore:

| h – 106 | = 7

h = 7 + 106 = 113 cm

When the equation is negative, therefore:

| h – 106 | = - 7

h = -7 + 106 = 99 cm

So the height must be 99 cm to 113 cm
