A city planner needs to make a model of the city. In real life, the tallest tree in the city is 40 feet tall. The shortest tree

Verdich [7]

To solve this you must set up what is called a proportion. A proportion is a way of comparing two comparing values where one of the four values is missing. In your problem the missing value is the height of the smallest tree in the model.

To set up a proportion, you need all of your values. The easiest way to do this is to list them:

Highest tree in real life: 40ft
Highest tree in model: 10ft
Smallest tree in real life: 4ft
Smallest tree in model: x

So know you can set your proportion like this:

40/4 = 4/x

(When setting up a proportion, you always want to have the values belong to each other. For example don't put the height of the small tree in the model underneath the value of the highest tree in real life.)

So know to find what the x values equals, we need to cross multiply. And then all that's left after that is to solve for x.

40 times x = 4 times 4

40x = 16

x = 2.5

The smallest tree in the model should equal 2.5 feet.

Hope this helps! :)

A 30 cm scale has one end broken. The mark at the broken end is 2.6 cm. How would you use it to measure the length of your penci

lidiya [134]

Answer:

the mark of the broken end is 2.6 cm so, we use the scale from the next full mark i.e. 3cm

Explanation:

we now measure the length of the pencil by keeping the 3 cm mark of the scale at it's left end.

The 3 cm value is then subtracted from the scale reading at the right side end of the pencil to obtain the correct length of the pencil. ✏️

(i i ) place the scale in the contact with object along it's length

(2) Your eyes must be exactly in front of the point where the measurements to be taken.
