18 cm is correct .
Step-by-step explanation:
The sum of two smaller sides is greater that the largest side.
It is given that the two sides of a triangle measure 8 cm and 15 cm.
Case 1: Let 8 cm and 15 cm. are smaller side. So,
<em>Third side < 8 + 15</em>
<em>Third side < 23</em>
<em>It means 3rd side must be less than 23</em>
<em>Case 2: Let 15 cm is the largest side.</em>
<em>15 < Third side + 8</em>
15 - 8 < Third side
7 < Third side
It means 3rd side must be greater than 7.
Since only 18 is less than 23 and greater than 7, therefore the possible length of third sides is 18 cm and option 2 is correct.
This should help!! Thanks! Let me know!
Retype your question that way we can help answer
Answer:
(a): 6 centimeters
(b): 72 inches
Step-by-step explanation:
Rule: From centimeters to inches, multiply centimeters × 8
so from inches to centimeters, divide inches by 8
Scale:
1 cm : 8 in
? cm : 48 in
6 cm : 48 in
Scale:
? in : 9 cm
72 in : 9 cm
Its just a matter of subbing ur numbers into the formula given
1. d = rt
when r = 144 and t = 18
now we sub
d = 144 * 18
d = 2592 <==
2. d = rt
when r = 56 and t = 3.5
sub
d = 56 * 3.5
d = 196 <==
3. A = L * W
when L = 2 ft and W = 15 inches....this one u have to convert to inches...2 ft = 24 inches...so L = 24 and W = 15
A = 24 * 15
A = 360 in^2 <==
4. A = L * W
L = 3m and W = 32 cm...have to convert to cm.....1 m = 100 cm...so 3 m = 300 cm
A = 300 * 32
A = 9600 cm^2 <==
u basically do the same for all the others....its just a matter of subbing and solving
