Answer:
3.5 meters
Step-by-step explanation:
- 1:4 = x:14 ; where x is the unknown length of A
- 1/4 = x/14 (Cross multiply)
- Giving us, 4×x = 14×1
- 4x = 14 (Divide both sides by co-efficient of x, which is 4)
- x = 14/4
- x = 3.5
- Therefore, the length of A is 3.5 meters.

Answer: Total price of all 5 cars = $35000.</h3>
Step-by-step explanation:
We are given total number of cars = 5 cars.
The mean of all of five cars = $7000.
Note: Total sum/value could be calculated by multiplying mean with the total numbers we have.
<em>Total price = Mean × Total number of cars.</em>
According to problem, mean is 7000 and total number of cars is 5.
<h3>Therefore, Total price of all 5 cars = 7000 × 5 = $35000.</h3>
Answer:

Step-by-step explanation:
3*4/3*3/5=12/5 or 2.4 cm³
Answer:
The equation of the axis of symmetry is x = 7
Step-by-step explanation:
Mathematically, we have the equation of the axis of symmetry as;
x = -b/2a
where a is the coefficient of x^2 = 1
b is the coefficient of x which is -14
So, the equation of the axis of symmetry will be;
x = -(-14)/2(1) = 14/2 = 7
So the equation of the axis of symmetry is x =7
