Answer:
Step-by-step explanation:
The average length of each car is
0.003 mile. The length of each car includes the bumper. The cars are in one lane. This means all the cars can be assumed to form a long line of cars that is uniform in length. This length is divided into equal lengths if cars.
The length of the traffic jam which is also the length of the line of is 7/8 = 0.875 mile long.
The number of cars would be in the that would be in the traffic jam will be length of the traffic jam/ length of each car. It becomes
0.875/0.003 = 292 cars
Answer:
it is 748

I know how to do math
Answer: 52.5
Step-by-step explanation: 2(3x+10)+2(x+10)=360 because all the sides of a rhombus equal 360 and alternate sides are equal
8x+20=360
-20=-20
8x/8=340/8
x=42.5
x+10. 42.5+10=52.5
D=52.5
First you plug the y into the equation you are substituting it into, this gives you
4x-3(-2)=18
multiply the -3 by the -2 to get 4x+6=18
Subtract the 6 from both sides to get 4x=12
Finally divide by 4 to get x=3
