Answer:
Side = 12 cm, side = 5 cm, side = 8 cm
Step-by-step explanation:
In order to form a triangle with non-zero area, the sum of the shortest two sides must exceed the longest side.
This will be the case for {5, 8, 12}, but not for any of the others.
___
The side lengths {5, 8, 13} will form <em>a triangle with zero area</em>. This is acceptable according to one version of the triangle inequality (a+b≥c) but not according to the other version (a+b>c). Since you are apparently expected to find one "right answer", we assume the answer you want is the one shown above.
Answer:
I believe it would be D.
Step-by-step explanation:
Answer:
let's use Pythagoras theorem,
h²=b²+l²
so,
ad²=ac²+dc²
6²=ac²+3²
36-9=ac²=27
√27 can be written as 3√3,
hence ac= 3√3
Answer:
300 girls
Step-by-step explanation:
100% represents the whole school
To calculate this amount divide 99 by 33% to find 1% and multiply by 100
school population = × 100 = 3 × 100 = 300
Answer:
60 minutes or 1 hour
Step-by-step explanation:
Set x as the amount of time she spends riding the bus
75 = time on bus + time on train
She spends 4 times as long on the train as on the bus so the time she spends on the train is 4x
75 = x + 4x
75 = 5x
x = 15 minutes on the bus
Since she spends 4 times as long on the train, we do 4 x 15 and we get 60 minutes which is 1 hour
