Area of the triangle:
A = 1/2 · c · b · sin A =
= 1/2 · 30 · 14 · 0.766 ≈ 160.87 ft²
Answer: 160.87 ft²
If Gabrielle takes 19 minutes to run 2 miles then how much time does he take to complete 1 mile.
The above is the ‘b’ question.
We can get to know who long he takes to complete 1 mile taking the mean of the two in the double number line.
In this case it would be, the mean if 2 to get 1 and the mean of 19,
The mean of 2 is,
2miles / 2 = 1 mile.
And the mean of 19 mins is,
19 mins / 2 = 9.5 mins.
Hence, Gabrielle takes 9.5 mins to complete 1 mile.
Hope this helps you. Plz let me know if you have any doubts.
Answer:
x=2
Step-by-step explanation:
-3x+7=1
subtract 7 from both sides: -3x+7-7=1-7
simplify: -3x=-6
divide both sides by -3: 
simplify: x=2
The perimeter P of the rectangular pasture of sides x and y is:
P=2x+2y=160 ft
if x=50 ft then y=(160-100)/2=30 ft
Area A=x*y=50*30=1500 ft^2
