Answer:

see explanation

Step-by-step explanation:

Using the given formula for area : A = $\frac{1}{2}$ bh

(a) given b = 8 and h = 5, then

A = $\frac{1}{2}$ × 8 × 5 = $\frac{1}{2}$ × 40 = 20 units²

(b) given A = 18 and b = 4, then

18 = $\frac{1}{2}$ × 4 × h = 2h ( divide both sides by 2 )

h = 9 units

14 = $\frac{1}{2}$ × 7 × b = 3.5b ( divide both sides by 3.5 )

b = 4 units

from the question, the robberies went down by 40%

Let the number of robberies in 2014 be x

Thus;

40/100 * 180

= 72

QUESTION 2 21 Write THREE equivalent actions for the following traction 25/50

MrMuchimi

The three equivalent fractions for $\frac{25}{50}$ are, $\frac{1}{2},\frac{5}{10},$ and $\frac{50}{100}$ .

<h3>What are equivalent fractions</h3>

Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value. For example, $\frac{2}{4}$ and $\frac{3}6}$ are equivalent fractions, because they both are equal to the $\frac{1}{2}$ . A fraction is a part of a whole. Equivalent fractions represent the same portion of the whole.
