Answer:
48 minutes.
Step-by-step explanation:
Number of dishes rinsed by Juan in <em>1</em><em> </em><em>m</em><em>i</em><em>n</em><em>u</em><em>t</em><em>e</em><em> </em>
= 480/80
= 6
Number of dishes rinsed by Kevin in <em>1</em><em> </em><em>m</em><em>i</em><em>n</em><em>u</em><em>t</em><em>e</em>
= 480/120
= 4
Number of dishes rinsed by Juan and Kevin in <em>1</em><em> </em><em>m</em><em>i</em><em>n</em><em>u</em><em>t</em><em>e</em>
= 6 + 4
= 10
Hence, time taken by Juan and Kevin to rinse the dishes
= 480/10
= <u>4</u><u>8</u><u> </u><u>m</u><u>i</u><u>n</u><u>u</u><u>t</u><u>e</u><u>s</u>.
Hence It will take <u>4</u><u>8</u><u> </u><u>m</u><u>i</u><u>n</u><u>u</u><u>t</u><u>e</u><u>s</u> for them to rinse the dishes.

Answer:2
Step-by-step explanation
1:(One shirt one pair of pants one sweater/One 2:(shirt one pair of pants one sweater/because don’t he only have two pears of shirts
If the mean height of 15 girls is 1.65m, the sum of the girls’ heights is 15×1.65=24.75m.
If the mean height of 10 boys is x metres, the sum of the boys’ heights is 10x m.
The sum of all 25 srudents’ heights is 25×1.682=42.05m.
Therefore, 24.75+10x=42.05, x=(42.05-24.75)/10=1.73m, the mean height of the boys.
33,000 a year
17 x 40 x 50 = 34, 000 a year
33,000 x 110 % = 36,300 a year
17 x 40 x 50 + 2,000 = 36,000 a year
The situation that will earn the most will be the third situation
hope this helps
