Draw a bar model that shows how the number of hours in March compares with the number of hours in February of this year.
gogolik [260]
Okay so first we need to find how many days are in March and February. March has 31 days and because this year was a leap year February has 29 days.

The next step is to convert days to hours.
March: 31x24=744
February: 29x24=696

Now its time to graph

Workout the length of AB. Give your answers to 3 significant figures.
german

Answer:

AB ≈ 6.71

Step-by-step explanation:

Calculate the length using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = A (- 1, 6) and (x₂, y₂ ) = B (5, 3)

AB = \sqrt{(5-(-1))^2+(3-6)^2}

    = \sqrt{(5+1)^2+(-3)^2}

    = \sqrt{6^2+9}

    = \sqrt{36+9}

    = \sqrt{45}

    ≈ 6.71 ( to 3 significant figures )
