Please help me with questions a, b, and c. Thank you
guapka [62]

Answer:

A: Not rational, because a rational number is any integer, fraction, terminating decimal, or repeating decimal. This does not show that.

B: In between 13 and 15, (200 rooted is 14.1) I know this because if you simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

C: He should make each side about 3.76 feet long. Because, 3.76^4 is 200, therefore it would become 200 square feet if each side is 3.76 feet long.

VashaNatasha [74]

Answer:

Step-by-step explanation:

1.Rewrite the decimal number as a fraction with 1 in the denominator

2.Multiply to remove 1 decimal places. Here, you multiply top and bottom by 101 = 10

3.Find the Greatest Common Factor (GCF) of 4 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,

so the answer is

0.4= 2/5
