What are the values of x and y?
will give brainliest if right.

x = 4.27

y = 9.07

Explanation:

In a right triangle, the altitude that’s perpendicular to the hypotenuse has a special property.

It creates two smaller right triangles that are both similar to the original right triangle.

If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar.

We use the property of similar triangle. Ratio of corresponding sides are same in case of similar triangle.

ΔADB is similar to ΔBDC (because ∠ADB = ∠BDC , ∠A=∠B and side BD = BD is common side)

NOw write the corresponding sides ratio

Now solve for x first

x =

x = 4.27

Now find y

y =

y = 9.07

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
