The perimeter of the triangle, namely the sum of all its 3 sides, is 110.
now, the three sides are in a 6:7:9 ratio, namely, if we divide 110 by (6+7+9), it will give us hmmm 110/22, a quotient of 22 equal pieces, namely how many times 22 would go into 110.
now, the small side, takes 6 of those pieces, the medium side takes 7 of them and the largest takes 9 of those pieces.
110/22 = 5
the small side is then 6(5).
the medium side is 7(5).
and the largest side is 9(5).
add them up, and you'd get the perimeter, 110 inches.
Answer:
19. 188
20. 18
21. 5
21. 4
Step-by-step explanation:
634.58 would round up to 635 and 436.79 would round up to 437.
20. 37.86 would round up to 38 and 19.92 would round up to 20.
21. 14.49 would round to 14 and 8.59 would round up to 9.
22. 7.45 would round down to 7 and 2.93 would round up to 3.
Using whole numbers, fractions and decimals, the following equations have the sum of 10.
1. 6 + 3 + 1 = 10
2. 2.25 + 4.25 + 3.50 = 10
3. 7/2 + 5/2 + 8/2 = 10
4. 25/5 + 15/5 + 10/5 = 10
5. 6 + 2. 25 + 1.75 =10
6. 3.26 + 4. 52 + 2.22 = 10
7. 5+ 3 + 2 = 10
8. 3/4 + 4/2 =10
