Height:shadow
so 3.5:1.06 and is the same as 50.5:x
we treat it as a fraction and get
3.5/1.06 and x/50.5
they should be equal
we know that if we multiply two equal fractions, with one flipped, then we will get 1 exg 1/2=4/8 1/2 times 8/4=8/8=1
so 3.5/1.06=x/50.5 3.5/1.06 times 50.5/x=1
176.75/1.06x=1
multiply both sides by 1.06x
176.75=1.06x
divide both sides by 1.06
166.745=x
round up to hundreds place
166.75m=accutal height
Answer:
well, 5% of 31348 is 1567.4

Step-by-step explanation:
Using cross- products, that is
= 
then ad = bc
Given the ratios
and 
Then equating and using cross- products
If both sides equate then the ratios are equivalent
= , then
4 × 21 = 6 × 14 ⇒ 84 = 84
Both sides are equal thus the ratios are equivalent
Answer:
B. -3d + 47.25
Step-by-step explanation:
Each of them has $15.75
Each spent $d
Amount each still has = 15.75 - d
Therefore, total amount the 3 of them has = 3(15.75 - d) = 3*15.75 - 3*d
= 47.25 - 3d
Which is also am equivalent of -3d + 47.25
