Answer:
72?-ft
Step-by-step explanation:
The tower shadow is 12 times as long as that of the post, so the tower will be 12 times as high as the post.
... 12 × 6?-ft = 72?-ft
-3=7x -10
-7x=-10+3
-7x=-7
x=1

Answer:
$2089
Step-by-step explanation:
One way to do this rounding is to add $0.50, then drop all of the fractional digits.
$2088.523125 + 0.50 = $2089.023125
Dropping all of the digits right of the decimal point gives $2089.
In the right triangle PQR:
Hypotenuse: QR = QN + NR = 12 + 6 = 18 cm
PN² = QN · NR
PN² = 12 · 6 = 72
PN = √72 = √(36 · 2 ) = 6√2 cm
PQ² = (6√2)² + 12² = 72 + 144 = 216
PQ = √216 = √(36 · 6 ) = 6√6 cm
PR² = 18² - (6√6)² = 324 - 216 = 108
PR = √108 = √(36 · 3) = 6√3 cm
Answer:
PN = 6√2 cm,
PQ = 6√6 cm,
PR = 6√3 cm.
