Answer:
13/30
Step-by-step:
First, you find the common denominator, which is 30. For the first fraction, multiply the bottom by five. Since you do that, you have to multiple the top by 5 as well, giving you 25/30. For the second problem, you multiple the top and bottom by six giving you 12/30. 25 minus 12 is 13 so you get 13/30.
Answer:
I would say A
Step-by-step explanation:
They are the same size, and the only angles that would be the same would be the original and their prime since it's only a reflection.

Option (a).
Step-by-step explanation:
1) Pedro decided to build a rectangular enclosure with an area of 36 m². How many meters of canvas will he have to buy to make the enclosure considering that one side will be 3 meters more than the other?
Let the length of the rectangle be x then the width will be (3+x) m
The area of a rectangular enclosure is 36 m².
To find how may meter of canvas will he have to buy to make the enclosure, we can find its perimeter. Firstly finding length and breadth using formula of area of rectangle.
Neglecting negative value, we get the length is 4.64 m
Width, b = (3+x) = (3+4.64) = 7.64 m
The perimeter of rectangle is :
P = 2(l+b)
P = 2(4.64 m+7.64 m)
P = 24.56 m
or
P = 25 m
Hence, 25 m of canvas will he have to buy to make the enclosure.
Answer:
D
Step-by-step explanation:
there were three times as many new subscribers in the 20-29 and the 30-39 age groups combined for the chronicle than in the 20-29 age group for the times.
so if you read 450 out of 720 that could be represented as a fraction as 450/720 but normally you would simplify it by finding the greatest common factor or the GCF and for this problem the GCF would be 90 so we would divide both sides by 90, so 450/90 is 5 and 720/90 is 8 so that leaves us with 5 as our numerator and 8 as the denominator or 5/8 also shown as 0.625(decimal version). That is all. I hope that this wasn't too confusing and if there are any wrong parts please do correct me . Thank you
