At a birthday party, the ratio of children to adults is 4:1. If the average time for the three-legged race for adults was 1 minu
zaharov [31]

Answer: The maximum the average can be for all the guests at the birthday party is 2 minutes 57 seconds.

Step-by-step explanation:

Since the ratio of adults to children is 4:1, then it follows that:

4/5 of the people are children

1/5 of the people are adults

A weighed average of the times would give:

1 minute 25 seconds = 85 seconds [for 1/5 of the people (the adults)]

3 minutes 20 seconds = 200 seconds [for 4/5 of the people (the children)]

(85 x 1/5) + (200 x 4/5) = 177 seconds

Therefore, the maximum the average can be for all the guests at the birthday party is 2 mins 57 secs.

Model: 9.5cm Actual : 30.5m The scale factor for a model is 5 cm =
Tju [1.3M]

Answer:

The scale factor for a model is 5 cm = 16.05 cm.

Step-by-step explanation:

Given:

Model: 9.5cm Actual : 30.5m and the scale factor for model is 5 cm.

Now, we need to find the actual shape for the scale factor 5 cm.

<em>Let the actual shape be x.</em>

Now, for getting the actual shape we set for proportion:

5:x :: 9.5:30.5

5:x = 9.5:30.5

Then, convert it into fractions:

\frac{5}{x} =\frac{9.5}{30.5}

Now, <em>on cross multiplying we get:</em>

9.5x=152.5

Dividing both sides by 9.5 we get:

x=16.05

Therefore, the scale factor for a model is 5 cm = 16.05 cm.
