Answer:
Green and Blue ribbon
Step-by-step explanation:
Given
They collect
Red Ribbon = ½ mile
Green Ribbon = ⅛ mile
Blue Ribbon = ¼ mile
To find?
Which colors of ribbons will be collected at the ¾ mile mark.
The interpretation of the question is to test which of the above fractions can divide ¾ without a remainder; in other words, multiples of ¾.
Testing each fraction.
Red Ribbon = ½
¾ ÷ ½
= ¾ * 2
= 3/2
= 1.5 or 1 Remainder 1
This is not an exact multiple of ¾. So, the red ribbon won't be passed here.
Green Ribbon = ⅛
¾ ÷ ⅛
= ¾ * 8
= 24/8
= 3
This is an exact multiple of ¾. So, the green ribbon will be collected.
Testing the last ribbon
Blue = ¼
¾ ÷ ¼
= ¾ * 4
= 3
This is an exact multiple of ¾. So, the blue ribbon will be collected.
Hence, the green and blue ribbons will be collected at ¾ mile mark
It would seem to be a good idea to cancel the (x + 3) factors to get f(x) = 1/(x - 4)
This is a hyperbolic graph with a vertical asymptote at x = 4.
However when x = -3 the factor (x + 3) = 0 so cannot be cancelled at this point. 0/0 is undefined.
The graph is drawn leaving a hole in the line at x = -3
The limits as we approach x = -3 from above or below that point get closer and closer to -1/7
The correct answer is A
Answer:
74.25feet
Step-by-step explanation:
Given the scale of a model train expressed as;
1in = 13.5feet
We are to express length of 5.5in in feet
5.5in = x
Divide both expressions
1/5.5 = 13.5/x
Cross multiply
1×x = 5.5× 13.5
x = 74.25feet
Hence the actual length of the car in feet is 74.25feet
First, put the numbers in numerical order from 4-13.
4,5,5,6,10,11,12,13
Then, the number that is in the middle will be the answer, which is 6 and 10. Then, you need to find the mean of these two numbers. To find the mean, add 6 and 10, then divide by two. The answer is then 8.
