The number of stamps and the cost are illustrations of unit rates
40 stamps would cost $22
The cost of 15 postage stamps is $8.25
Start by calculating the unit rate of the stamps.
So, the number of stamps for $22 is calculated by dividing $22 by the unit rate.
So, we have:
Hence, 40 stamps would cost $22

ANSWER
405m
EXPLANATION
We know the opposite side of of the right triangle to be 4629m and the given angle is 85°.
Since we want to find the adjacent side which is x units, we use the tangent ratio to obtain,
Solve for x.
x=404.985
To the nearest meter, x=405m
Answer:
PR = 24.5
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, that is
=
( cross- multiply )
18PR = 28 × 15.75 = 441 ( divide both sides by 18 )
PR = 24. 5
