This are fractions because they are not mixed fraction by the way those two are 0.5
Answer:
Bruh it's pretty ez.
Step-by-step explanation:
Instead of 2 liters, add 100 ml to 5 liters and u'll get de answer.
Answer:
Step-by-step explanation:
3/4r + 1/2(r+6)=23
3/4r + 1/2r +3=23
5/4r =20
Multiplying by 45 yields r=16
DaMarcus's speed is r=16 miles per hour & Fabian's speed is r+6=22 miles per hour.
Answer:
Explanation:
3. Find LCM of (30, 9):
30 = 2 x 3 x 5
9 = 3 x 3
Thus : LCM(30, 9) = 2 x 3 x 3 x 5 = 90
Therefore, in 90 days he will has both activities again.
4. Determine whether its possible to construct a triangle with the given length.
a.
8 + 9 > 11 (true)
8 + 11 > 9 (true)
9 + 11 > 8 (true)
Thus 8,9 and 11 can be construct as a triangle.
b.
4 + 5.1 > 12.5 (false)
4 + 12.5 > 5 (true)
12.5 + 5 > 4 (true)
Thus, 4, 5.1 and 12.5 cannot be constructed as a triangle.
If you want a shorter way to find the perimeter then just multiply how many sides and the length of the side.
4 x4 = 16
However this only works if the 2D shape is an equilateral. So this trick only works in certain situations.
