Question 74 pts.
eimsori [14]

Answer:

1,187 bu/hr

Step-by-step explanation:

4.8 mi/hr

240 inches

Efficiency: 85% (0.85)

120 bushels/acre

1 acre = 6 272 640

1 mile = 63 360 inches

4.8 miles = 304 128 inches

120/6 272 640 x 240 = 5/1089 (bushels/inch)

5/1089 x 304 128 x 85% = 1 186.9 = 1187 bu/hr

Wow, that's hard for me :) Hope it's helpful

Can someone help me? Will make brainiest :)
kherson [118]

Answer:

D

Step-by-step explanation:

BH is perpendicular to AC since an orthocenter is a point at which the three altitudes of a triangle intersect. The altitude of a triangle is that line that passes through its vertex and is perpendicular to the opposite side. Since you know that BH is an altitude due to Point H being an orthocenter, you know that BH is perpedendicular to AC.
