The true statement is as follows:

The product 13 / 4 × 2 can be used to find the unit rate in cm per hour.

After one hour, the height of the candle will have decreased by 6 1 / 2 cm.

Rate is the ratio between two related quantities in different units.

The height of the candle decreases from 10 cm to 6 3 / 4 cm after burning for 1 / 2 hours.

6 3 / 4 cm = 27 / 4 cm

10 - 27 / 4 = 40 - 27 / 4 = 13 / 4 cm

Therefore, 13 / 4 cm of candles were lost in 1 / 2 hours.

Rate = 13 / 4 × 2 = 26 / 4 = 13 / 2 cm per hour

Therefore, the product 13 / 4 × 2 can be used to find the unit rate in cm per hour.

13 / 4 + 13 / 4 = 13 + 13/ 4 = 26 / 4 = 13 / 2 = 6 1 / 2 cm.

Therefore, after one hour, the height of the candle will have decreased by 6 1 / 2 cm.

Softa [21]

Answer:

For Australia: 22,044,350

For China: 1,545,744,200

For Mexico: 145,507,500

For Zaire: 92,237,875

Step-by-step explanation:

For Australia: Population in 2000 is 19,169,000 and it is increasing steadily at a rate of 0.6% per year.

Therefore, the population in the year 2025 will be

$19169000[1+\frac{0.6 \times 25}{100} ]= 22,044,350$ (Answer)

For China: Population in 2000 is 1,261,832,000 and it is increasing steadily at a rate of 0.9% per year.

Therefore, the population in the year 2025 will be

$1261832000[1+\frac{0.9 \times 25}{100} ]= 1,545,744,200$ (Answer)

For Mexico: Population in 2000 is 100,350,000 and it is increasing steadily at a rate of 1.8% per year.

Therefore, the population in the year 2025 will be

$100350000[1+\frac{1.8 \times 25}{100} ]= 145,507,500$ (Answer)

For Zaire: Population in 2000 is 51,965,000 and it is increasing steadily at a rate of 3.1% per year.

Therefore, the population in the year 2025 will be

$51965000[1+\frac{3.1 \times 25}{100} ]= 92,237,875$ (Answer)
