sleet_krkn [62]

Answer:

The answer is "The cops were correct because the average speed would have been about 39.73 miles per hour as per the calculations."

Step-by-step explanation:

Finding the average skid distance:

Average=\frac{70+71+72}{3}=\frac{213}{3}=71

Calculating the skid:  

S=\sqrt{30 \times D \times f\times n}\\\\  

   =\sqrt{30 \times 71 \times 0.78\times 0.95}\\\\=\sqrt{1,578.33}\\\\=39.73

Answer:

  £592 for 16 boxes

Step-by-step explanation:

The classroom floor area is ...

  A = LW = (8.8 m)(2.2 m) = 19.36 m²

The cupboard floor area is ...

  A = (2.3 m)(2.1 m) = 4.83 m²

Then the total area to be covered is ...

  19.36 m² +4.83 m² = 24.19 m²

At 1.6 m² per box, the number of boxes required is ...

  (24.19 m²)/(1.6 m²/box) = 15.12 boxes

If we assume we can only purchase whole boxes, we need to purchase 16 boxes to cover the floor. The cost will be ...

  (16 boxes)(£37/box) = £592 . . . . cost of laminate to replace the floor

Some of the steps in Liam solution to 3. 5 (1.25x + 0.5) = 10.5 are shown complete the boxes with reasons for lines 2 and 4 of L
babymother [125]

Answer:

x = 2

Step-by-step explanation:

Given the equation;

3. 5 (1.25x + 0.5) = 10.5

Open the parenthesis

3.5(1.25x) + 3.5(0.5) =10.5

4.375x + 1.75 = 10.5

4.375x + 1.75 -1.75= 10.5-1.75

4.375x = 8.75

Divide both sides by 4.375

4.375x/4.375 = 8.75/4.375

x = 2

Hence the solution to the equation is 2
