Answer:
Step-by-step explanation:
Surface area → area of 2 bases + area of 6 rectangles
Area of base is given
Area of rectangle → length × width
Answer:
the width=15; the length=20
Step-by-step explanation:
1. to solve the given equation: x²+5x-300=0;
x₁= -20; x₂=15, where 'x' can be only positive value. It means x=15;
2. according to the condtition the length is more, it means 15+5=20.
3. the width is x=15; the length is 20.
Answer:
The average rate is 35 miles per hour
Step-by-step explanation:
To get from town A to town B takes 3 hours. The distance is 100 miles
To get from town B to town c takes 1 hours. The distance is 40 miles
To find the average rate , we need to find the total distance and divide by the total time
Total distance = 100 + 40 = 140 miles
Total time = 3 hrs + 1 hr = 4 hours
distance = rate * time
140 miles = rate * 4 hours
140/4 = rate
35 = rate
The average rate is 35 miles per hour
