Answer:
357 mi²
Step-by-step explanation:
The shape is made of a triangle and a half-square
we will calculate the area of each one
let A1 be the area of the half-circle:
A1= (10²*π)/2 = 50π mi²
Let A2 be the area of the triangle:
A2= 10*20=200 mi²
let At be the total area:
At =A1+A2= 200+50π =357.07≈ 357 mi²
Answer:
7 minutes 48 seconds.
Step-by-step explanation:
Average speed for the whole journey is
distance / time, so
105 = (2*80)/ (t + t2)
where t is the time when it is moving and t2 is the time it stays at town Q.
Time for journey P to Q
= distance / speed
= 80 /120
= 2/3 hours,
Time for journey Q to P
= 80/110
= 8/11 hours
So t = 2/3 + 8/11
= 46/33 hours.
- and substituting in the equation for the whole journey:
160 / (46/33 + t2) = 105
105*46/33 + 105*t2 = 160
105 t2 = 160 - (105*46)/33
= 160 - 146.364
= 13.636
t2 = 13.636/105 = 0.1299 hours.
= 7 minutes 48 seconds.
Answer:
B = 38°
Step-by-step explanation:
A straight angle is 180°. If your four angles total a straight angle, then ...
60 +2x +3x +25 = 180
95 = 5x . . . . . . subtract 85
x = 19 . . . . . . divide by 5
2x = 38 . . . . . angle B is 38°
