Answer:
73.46yd²
Step-by-step explanation:
Area of Triangle = ½ * b * h
= ½ * 16 * 19
= 152yd²
Area of Circle= pi * r² = 5² pi = 25 pi = 78.54yd²
area of shaded part= 152 - 78.54
= 73.46yd²
Answer:
B) Beth went back toward her origin.
Step-by-step explanation:
From 0 to 6, the graph increases. The dependent variable in this case is position and the independent variable is time; this means for this portion of the graph, as time increases the position increases as well.
From 6 to 10, the graph decreases. As time increases the position decreases. This means she goes back to her original position.
Walk = x + 6
Bike = x
Driven = x
x + x + x + 6 = 24
combine like terms
3x + 6 = 24
subtract 6 from both sides
3x = 18
divide both sides by 3 to isolate x
x = 6
Walk = x + 6 = 6 + 6 = 12
12 students walk to school.
D because it’s the peak on both the graphs
Answer:
26.4 km/hr
Step-by-step explanation:
Sofia and Diego drive to work.
For Sofia
We convert miles to km
Sofia drives 72 miles in 1.5 hours.
1 mile = 1.6 km
72 miles = x
x = 72 × 1.6 km
x = 115.2 km
We find the speed in km/hr
Speed = Distance /Time
= 115.2km/1.5 hours
= 76.8 km/hr
For Diego
Diego drives 126 km in 2 hour 30 min.
Speed = Distance/Time
Time = 2 hour 30 min = 2.5 hours
Speed = 126km/2.5 hours
= 50.4 km/hr
The difference between their average speeds in km/h is calculated as:
76.8 km/hr - 50.4 km/hr
= 26.4 km/hr
