Answer:
21 miles
Step-by-step explanation:
Each of the distances is the same, so we have ...
5x +4 = 15x -30
34 = 10x
3.4 = x
Then the distances are ...
5(3.4) +4 = 21 . . . . miles
Bert and Ernie each live 21 miles from Big Bird's nest.
First you can convert 45 miles per hour to feet per hour:
45 × 5,280 = 237,600 feet per hour
Now you must remember that there are 60 minutes in an hour, and 60 seconds in a minute. So you can divide 237,600 feet per hour by 60 to get feet per minute:
237,600 ÷ 60 = 3,960 feet per minute
Now you just have to divide 3,960 by 60 again to get feet per second:
3,960 ÷ 60 = 66 feet per second
Now you know how fast the car can travel (in feet) in a second. So to work out how many feet it travels in 3 seconds, you just have to multiply 66 by 3:
66 × 3 = 198 feet
Therefore your final answer is <em>198 feet</em> :)
To find the unit rate divide the charge by the number of nights: 723/3=$241.
Volume of a triangle: 1/2(2b × h)
The 1/2 and 2 cancel each other out, so it's just b × h.
Area of base: 8 × 8 = 64 cm²
Height: 12 cm
64 × 12 = 768
The volume of the triangle is 768 cm³.
