vodomira [7]

Answer:

Figure ABCD is graphed on a coordinate plane.
Phoenix [80]
1. BC is 1+3=4 (units)

2. AD is 3+5= 8 (units)

3. Draw the altitude CH from point C, as shown in the figure.

4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.

5. CD^2=HD^2+CH^2

CD^2=2^2+4^2=4+16=20

CD= \sqrt{20}= \sqrt{4*5}= \sqrt{4} *  \sqrt{5}=2 \sqrt{5}= 4.47

6. AB=CD=4.47 because the trapezoid is isosceles.

7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)

2476 adults watch a cricket match. The ratio men : women is 3 : 1 How many more men than women watch the match?
poizon [28]

he ratio of 3:1 involves 4 units. 3 men +1 woman.

Find how many people each unit represents:

    4units        2476 people

Therefore each unit represents 2476/4 = 619 people per unit

Now, take the ratio, and multiply up:

3:1  =>  3619:1619   =>   1857:619    You check this is right by adding the two fractions:

1857 men + 619 women = 2476 people therefore, we are correct

The number of men more than women = Number of men - Number of women

                                                       = 1857-619 = 1238 and that is your answer
