The area of a rectangle is given by the product of its length and width.
A = l·w
Then the lenght is found by dividing this equation by w to get
l = A/w
Filling in the given information, we can find the length of the runway as
l = (2165400 ft²)/(180 ft)
l = 12,030 ft
Answer:
7
Step-by-step explanation:54x=60x-42, -6x=-42, divide both sides by six then you get 7
Answer:
<u>35 coins are "other" coins</u>
Step-by-step explanation:
72% of 125 coins were foreign. That means 28% of the coins are not foreign ("other coins").
28% 0f 125 = 0.28*125 = 35 coins were "other" coins
Answer:
y^2 - x^2 = 11
Step-by-step explanation:
y^2 - x^2 = ?
Substitute.
y = 6
x = 5
Becomes:
6^2 - 5^2 = ?
Solve.
6^2 = 6 x 6
6 x 6 = 36
5^2 = 5 x 5
5 x 5 = 25
36 - 25 = 11
First, all the heights have to be converted to similar units, say feet.
Therefore,
Building= 20 feet
Tree = 252*0.083333 = 21 feet
Flagpole = 6*3 = 18 feet
The tallest of the three is the tree and thus should cast the longest shadow. However, it should be noted that at exactly noon when the sun is overhead, all the three will have equal length of shadow (that is, 0 feet long).
