There are infinitely How many pairs of numbers of which the sum of their cube roots is zero give two of these pairs
ivanzaharov [21]

Answer:

Infinite pairs of numbers

1 and -1

8 and -8

Step-by-step explanation:

Let x³ and y³ be any two real numbers. If the sum of their cube roots is zero, then the following must be true:

\sqrt[3]{x^3}+ \sqrt[3]{y^3}=0\\ \sqrt[3]{x^3}=- \sqrt[3]{y^3}\\x=-y

Therefore, any pair of numbers with same absolute value but different signs fit the description, which means that there are infinite pairs of possible numbers.

Examples: 1 and -1; 8 and -8; 27 and -27.

A tropical storm has been moving at 15 miles per hour for the past two days. Bess recorded that the storm moved 135 miles yester
Allushta [10]

Answer:

Bess has been keeping track of the storm for 14 hours.

Step-by-step explanation:

The tropical storm has been moving at 15 miles per hour.

Bess recorded that the storm moved 135 miles yesterday and 75 miles today. Total distance covered by storm is

135+75=210

The relationship between distance speed and time is defined as

speed=\frac{distance}{time}

15=\frac{210}{time}

time=\frac{210}{15}

time=14

Therefore, Bess has been keeping track of the storm for 14 hours.
