Answer:

2.6

Step-by-step explanation:

Answer:

2.6

Step-by-step explanation:

Let us assume that the unit of measurement is centimetre (cm)

To obtain the value of A, do the following:

From the diagram above, we can say that the scale is 5 cm to 1 unit since there are 5 lines before a number.

Next, we shall determine the value of 1 cm.

5 cm = 1 unit

Therefore,

1 cm = 1/5 = 0.2 unit

This means that 1 small line is equivalent to 0.2 unit.

Now we shall determine A as follow:

A is exactly 3 lines (3 cm) after number 2.

1 cm = 0.2 unit

3 cm = 3 x 0.2 = 0.6 unit

Now, add 0.6 to 2 to obtain the value of A.

A = 2 + 0.6

A = 2.6

Therefore, A correspond to 2.6

A = 2 + 0.6

A = 2.6

Therefore, A correspond to 2.6

In the year 2015 Emily was three times as old asKaitlin. By the year 2021 Kaitlin will be half asold as Emily will be. How old w

weeeeeb [17]

In 2000 Emily was 9 years old.

Given that in the year 2015 Emily was three times as old as Kaitlin while by the year 2021 Kaitlin will be half as old as Emily will be, to determine how old was Emily on the year 2000 the following calculation must be performed:

2015 = E = 3K
2021 = E = 2K
24 /// 8 --- 30 /// 14
18 /// 6 --- 24 /// 12
18/6 = 3
24/12 = 2
2015 = Emily was 24 years old
24 - (2015 - 2000) = X
24 - 15 = X
9 = X

Therefore, in 2000 Emily was 9 years old.
