Answer:
Perimeter of trapezoid = 6x - 1
Step-by-step explanation:
a trapezoid has two bases (x and 2x) and two sides ( x+2 and 2x-3)
To find the perimeter you add all both bases and both sides
Perimeter of trapezoid = x + 2x + (x+2) + (2x-3); add x's
Perimeter of trapezoid = 6x + 2 -3 ; subtract the numbers
Perimeter of trapezoid = 6x - 1
Answer: 23.2 miles per hour
Step-by-step explanation:
He ran 100 meters in 9.63 seconds.
First convert the number of meters he ran to miles:
= 100 * 3.28
= 328 feet
= 328/5,280
= 0.062121212 miles
Convert the seconds to hours:
= 9.63 / 60
= 0.1605 minutes
= 0.1605/60
= 0.002675 hours
Speed in miles per hour is:
= 0.062121212 / 0.002675
= 23.22
= 23.2 miles per hour
40÷5= 8 You have to see how many time 5 can go into 40
1. see how many times 5 goes into 4 none so the first number is 0
2. then you see how many time 5 can go into 0 o times
3. so you have to see how many time you can count 5 into 40
(count by 5's) 5,10,15,20,25,30,35,40 that should be 8 times total!
