Answer:
Angle HFG + angle ACB = 90°
Angle EFC = Angle DFG
Angle HFG + angle DFH = angle DFG
= 90°
The answer is B Angle DFH = angle ACB
Hope this helps!
Total cost
=$100 - g
Total number of bags = 7
Cost of each bag
= total cost / total number of bags
=(100-g) / 7
(note: the parentheses are VERY important)
45 min is 3/4 of an hour, 3/4 0f 40 km/h=30 km
75km/h x 2hr=150km
=180km
Total time:3hr
180kh/3hr=60km/h
sorry if im wrong
Answer:
Call the sister's height x. The boy is twice as tall, so that's 2x. The father is 30 cm taller than the boy, so his height is 2x + 30. The combined height is 3.8m, which is 380cm. Now you can write an equation
x + 2x + 2x + 30 = 380
collect like terms
5x = 350
x = 70
the sister is 70cm tall, the boy is 2*70 = 140 cm, and the father is 140 + 30 = 170cm
Check that the heights add up to 3.8m: 70 + 140 + 170 = 380 cm = 3.8m. Correct

Answer:
-2
Step-by-step explanation:
The slope of a line is rise over run between two points.
In this line there is an upward rise of 2, and a horizontal run of -1.
Therefore the slope is just 2/-1 which is -2.
