How tall is the tower?

Karo-lina-s [1.5K]

Answer:

93.6 ft

Step-by-step explanation:

$\bf \cfrac{AB}{BC} = \tan(60)$

$\bf \cfrac{x}{50} = \sqrt{50}$
$\bf x = 50 \sqrt{3}$

Length of tower:-

$\bf x + 7$
$\bf 50 \sqrt{3} + 7$
$\bf 93.6025$
$\bf = 93.6$

Therefore, the tower is 93.6ft tall.

Answer: The price of Zoe's dinner before sales tax and tips is $13.96.

Step-by-step explanation:

Since we have given that

Amount Zoe paid after sales tax and tip = $18.60

Let the price before tax be 'x'.

Rate of sales tax = 11%

So, it becomes,

$\frac{11}{100}\times x\\\\=0.11x$

So, Amount after tax, our equation, becomes,

$x+0.11x=\$18.60\\\\1.11x=\$18.60\\\\x=\frac{18.60}{1.11}\\\\x=\$16.75$

Now, let the amount before tips be 'y'.

Rate of tips = 20%

So, it becomes,

$\frac{20}{100}\times y\\\\=0.2y$

So, After tips it becomes,

$y+0.2y=\$16.75\\\\1.2y=\$16.75\\\\y=\frac{16.75}{1.2}\\\\y=\$13.96$

Hence, The price of Zoe's dinner before sales tax and tips is $13.96.

Answer:

Area of the triangle = 210 cm^2 .

Step-by-step explanation:

Perimeter of triangle = 4x + 1 + 3x - 1 + 3x = 70

10x = 70 - 1 + 1 = 70

x = 7.

Area A = 1/2 * base * height

= 1/2 * 3x * (3x - 1)

= 1/2 * 3(7) * (3(7) -1)

= 1/2 * 21 * 20

= 210.
