Answer:
=14.69km²
Step-by-step explanation:
We can use the Hero's formula to calculate the area
A= √(s(s-a)(s-b)(s-c))
s is obtained by adding the lengths of the three sides of the triangle and then dividing by 2, a, b and c are the ides of the triangle.
S=(5+6+7)/2
=9
A=√(9(9-6)(9-5)(9-7))
=√(9×3×4×2)
=√216
=14.69km²
1 and 1/6
1 and 1/12
1 and 1/10
1 and 1/4
Hope this helps! a
May I please get brainliest? :D
1/2=5/10
1/5=2/10
1/2+1/5
=5/10+2/10
=7/10
So your answer is 7/10
Answer:
4/15 i'm pretty sure
(Sorry if it's wrong, it's been awhile since i've done stuff like this)
The relationship between speed (s), distance (d), and time (t) is s = d/t. Substituting the given information, we see that 105/t < 70105 < 70t1.5 < t So, the time will be AT LEAST 1.5 hours. Hope this helps.
