Answer:
40
Step-by-step explanation:
a^2+b^2=c^2
therefore c^2-b^2=a^2
41x41=1681
9x9=81
1681-81=1600
Sqrt1600=40
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.
Yes, the answer would be "b". There are a total of 313 people wanting to ride it. Only 72 people can ride it at a time. "x" in the drawing represents how much times is takes for all the people to ride it. You are correct, hope this helps! =)
