Answer:
Step-by-step explanation:
We need to find the fractional amount of the total that is 2d and 4d size nails.
It is given 2d nails are 2/4th of the total. Also
It is given 4d nails are 1/4th of the total.
Hence 2d and 4d comprises of 2/4 + 1/4 = 3/4th of the total
so, 2d and 4d is 3/4th of the total
The answer would be 6, hope this helps
Answer:
I think 15.
Step-by-step explanation:
20 ÷ 5=4 and 5 × 3=15.
Yes they are similar because one they're both 90 degree angles, and two if you divide 12÷8 it'll equal 1.5
Same thing with the other side. If you divide 36÷24 it'll equal 1.5
and this shows proof of similarity since its like half the sides, but they both have the same angles.
(Sides doesn't matter, its the angles)
20,112.5 meters
Multiply the length of the track by 10, then multiply that number by 5
