The average is 0.9
-2.5 + 5.2 + 1.7 + (-0.8) = 3.6
3.6 / 4 = 0.9
Answer: 1. 10
2. an = an - 1 + 7 where a1 = -10
Step-by-step explanation:
The sentence describing the scale of the model is 1 m represents 40m.
Given,
The length of the ship = 120 m
A scale model of the ship is made.
The length of the model = 3 m
We have to find that, 1m in model represents how much meter of the original.
Scale model;
A physical model that is geometrically similar to an object is called a scale model (known as the prototype). Scale models may be larger than small prototypes like anatomical structures or subatomic particles, but they are often smaller than huge prototypes like cars, buildings, or people.
Here,
Original ; scale model
120 ; 3
That is,
120/3 = 40
Therefore,
1 meter in scale model represents 40 m of the original ship.

Answer:
he would have to work 43 hours
Step-by-step explanation:
So if we know that at job one he gets payed 860 dollars a week and in job two he gets payed 20 per hour all we need to do is divide 860 by 20 to find the number of hours in a week and it would be 43
True
Because a negative square root is an i
