Answer:
C: 11.5 cm, 4.2 cm, 7.6 cm
Step-by-step explanation:
In order for the lengths to form a triangle, the sum of the shortest two must exceed the longest.
A. 5.4 +5.4 = 10.8 < 12.6
B. 1.3 +5.9 = 7.2
C. 4.2 +7.6 = 11.8 > 11.5 . . . . will make a triangle
D. 3.1 +6.6 = 9.7 < 10.4
15.5 (Just round 15.49 to the nearest tenth)
Answer:
1600mm
Step-by-step explanation:
total length of the line segment = length of the first string + length of the second string
to add the strings together, convert the length of the first string to millimetre
1cm = 10mm
95 x 10 = 950mm
950mm + 650mm = 1600mm
How you simplify fractions is figuring out what the highest number that can go into them is.
I now that's a bit confusing but I'll explain.
In this case, 2 can go into both 10 and six, (because 2×5=10 and 2×3=6) and no higher number can, so the simplified version of 6/10 is 3/5. (the numbers we multiplied by 2)
