Can a rational number be a irrational number

1 answer:

4 0

Answer:

No. Rational numbers are different from irrational numbers. Rational numbers are numbers that can be written as a fraction. Rational numbers can be a terminating decimal (a number with digits that end/do not repeat) or a repeating decimal (a number with digits that repeat continuously in a pattern). On the other hand, an irrational number is a number that is continuous, and its digits are random.

If A = 30° and r = 12, find x. (Round your answer to the nearest whole number.)

Margaret [11]

Answer:

$\boxed{12}$

Step-by-step explanation:

A = 30° and r = 12

$\sin A = \frac{r}{r + x}$

$\sin 30 = \frac{12}{12 + x}$

$\frac{1}{2} = \frac{12}{12 + x}$

$1(12 + x) = 2(12)$

$12 + x = 24$

$x = 24 - 12$

$x = 12$

What is the measure of ZB? 28 36 B [?] degrees Enter

Sindrei [870]

All triangles have a measurement of 180 degrees. Therefore, we can use this information to make an equation to find the value of angle B.

Angle B = 180 - (28 + 36)
Angle B = 180 - 64
Angle B = 116

So, angle B is equal to 116 degrees.

When Colton commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 41 minutes and a

N76 [4]

Answer:

(34, 48)

Step-by-step explanation:

According to the Empirical Rule, 95% of normally distributed data lie within two standard deviations of the mean. That, in turn, means 95% of the data in this problem lie within 2(3.5 min), or 7 min, of the mean:

41 - 7 < mean < 41 + 7, or

34 < mean < 48, or simply (34, 48)
