A population of ants is 10,000 at the start of April. Since then, it triples each month.
Kryger [21]

Answer:

Month since April                                   Number of Ants

          0                                                         10,000

           1                                                         30,000

          2                                                         90,000

          3                                                        270,000

          4                                                         810,000

Every month, the ant population triples so the multiply the previous population by 3 to find out the new population.

0 months from April = 10,000 * 1 = 10,000 ants

1 month from April = 10,000 * 3 = 30,000 ants

2 months from April = 30,000 * 3 = 90,000 ants

3 months from April = 90,000 * 3 = 270,000 ants

4 months from April = 270,000 * 3 = 810,000

bekas [8.4K]

Answer:

Mrs. Stern washed more

\frac{7}{20} laundry still needs to be washed.

Step-by-step explanation:

Total amount of laundry: \frac{20}{20}

\frac{20}{20} -\frac{2}{5}-\frac{1}{4} =

\frac{20}{20} - \frac{8}{20} -\frac{5}{20} =

\frac{7}{20} of the laundry still needs to be done.

Mrs. Stern washed \frac{8}{20} of the laundry.

Her son washed \frac{5}{20} of the laundry.

Mrs. Stern washed more laundry than her son.
