Find the cost of tiling a rectangular plot of land 300 m long and 150 m wide at the rate of $6 per square m.

SVETLANKA909090 [29]

Answer:

$270,000

Step-by-step explanation:

First, find the area of the plot using the formula A = lw

A = lw

A = (300)(150)

A = 45,000

Then, multiply this by 6 to find the total cost:

45,000(6)

= 270,000

So, the cost to tile the plot is $270,000

A guidebook says this tower is 50m tall.Is that correct? given deegrees are 27° and 46°<br>

inysia [295]

9514 1404 393

Answer:

yes

Step-by-step explanation:

The tower is about 50.1 meters tall. The guidebook is correct.

The distance from the base of the tower to the angle vertex is ...

d1 = h/tan(46°)

d2 = d1 +50 = h/tan(27°)

Then the height of the tower is ...

h/tan(46°) +50 = h/tan(27°)

50 = h(cot(27°) - cot(46°))

h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692

h ≈ 50.1544 . . . meters

The tower is more than 50 meters high.
