Percy Cod takes a walk around the perimeter path of his local park. The park is in the shape of a rectangle which is 400m wide a
lozanna [386]

Answer:

2800m

Step-by-step explanation:

Assumption:

Start point from which Percy Cod walks is "x"

If he walks around a perimeter that is the shape of a rectangle,

Length of area = L = 1000m

Width of area = W = 400m

Distance around the rectangle = D = 2 * (L + W)

D = 2 * (400+1000)

D = 2 * 1400

D = 2800m

The ratio of blue jays to Robin's was 6 to 7. If there were 84 Robins, how many blue jays were there?​
Paul [167]

Answer:

72

Step-by-step explanation:

<em>Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.</em>

<em>6 to 7 can also be express as 6/7</em>

<em>Thus, we can set up a proportion</em>

<em>6/7 = x/84</em>

<em>Now, we have to solve for x</em>

<em>x = 72</em>

<em>Hence, if there were 84 robin there would be 72 blue jays.</em>
