fgiga [73]

Answer:

7 weeks

Step-by-step explanation:

80 ÷ 20 = 4

She over those four week she makes 17 per week. So,

17 × 4 = 68

Next, divide the product by 20:

68 ÷ 20 = 3.4

But 3.4 is only 3 full weeks so then its 3.

Lastly, add the 3 weeks we just solved for the the 4 weeks from before and you get 7 weeks.

So, Anna will be able to supply the "Unique" store for 7 weeks.

I HOPE I HELPED!!!!!!!!!! :))))))

What is the quotient of 1.728 x 109 and 4.8 x 106 expressed in scientific notation?​
fenix001 [56]

Step-by-step explanation:

\to 1,728 \times {10}^{9}

= 1,728 \times {10}^{9}

= 1,728 \times 1.000.000.000

= 1.728.000.000

1,728 \times {10}^{9} = 1.728.000.000

\:

\to 4,8 \times {10}^{6}

= 4,8 \times {10}^{6}

= 4,8 \times 1.000.000

= 4.800.000

4,8 \times {10}^{6} = 4.800.000
