Answer: It will take 3.33 hours to complete it's entire route 10 times.
Step-by-step explanation: Time taken to complete it's entire route 3 times= 1 hour
∴Time taken to complete it's entire route 10times = 10/3
= 3.33 hours

Well, there are actually millions of colors in the rainbow, (every color that the human eye can see), but I do understand the question you're asking:
-- When Sara is ready to make her first selection, there are seven things with different colors in the pot, and one of them is red.
The probability that she picks the red one is ( 1 / 7 ).
The question says "with replacement". That means that after she selects it and looks at it, she puts it back in the pot. So . . .
-- When she's ready to make her second selection, the same seven things with different colors are still in the pot. One of them is orange.
The probability that she picks the orange one is ( 1 / 7 ).
-- The probability of BOTH selections being successful (the color she wants) is
(1/7) x (1/7) .
That's <em>(1/49)</em>, which is about <em>2.04 percent</em> .
Answer:
Perimeter of ABCD = <u>56 units</u>
Perimeter of WXYZ = <u>140 units</u>
Step-by-step explanation:
<u>To find the perimeter of ABCD, find the sum of all sides</u>
18 + 18 + 10 + 10 = 56
<u>To find the side lengths of WXYZ, use the equation:</u> 
45/18 = 2.5
<em>You can also cross multiply to find the missing side lengths, but I'll show you this other way...</em>
<u>Multiply the pre-image side lengths by 2.5</u>
18 × 2.5 = 45
10 × 2.5 = 25
<em>45 and 25 of the new side length of WXYZ</em>
<em />
<u>To find the perimeter of WXYZ, find the sum of all sides.</u>
45 + 45 + 25 + 25 = 140
WX = 45, XY = 25, YZ = 45, ZW = 25
