Amodel is made of a car. the car is 10 feet long and the model is 7 inches long. what is the ratio of the length of the car to the length of the model? a. 10 : 7 b. 7 : 120 c. 120 : 7 d. 7 : 10

1 foot is 12 inches,

The real length of the car which is 10 feet, that equals to 10*12in=120 in, is represented by 7 inches in the model.

Thus 120 inches in reality, are represented by 7 inches in the model.

We describe this ratio by 7:120  (the value in reality comes second).

Answer :         B  7:120

Idon’t actually know but have you asked google yet

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
