1 answer:

6 0

Product means multiplication
is means equal
less than means subtraction
times means multiplication

The product of 9 and a number is 12 less than three times that number.

Lets say this number is 'n'

then:

9n = 3n-12

Add 12 on both sides

9n + 12 = 3n

Subtract 9n on both sides

12 = -6n

Divide by -6 on both sides to isolate n

n= -2

Your final answer is

$\Huge{\boxed{\bf{n=-2}}}$

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

GarryVolchara [31]

Answer:

85.1 ft

Step-by-step explanation:

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

We solve using the Trigonometric function of Cosine

cos y = adjacent/hypotenuse

y = angle = 20°

Adjacent = 80 ft

Hypotenuse = ?

cos 20 = 80/Hypotenuse

Hypotenuse = 80/cos 20

x = 85.134221798 ft

Approximately = 85.1 ft

Length of the slide = 85.1 ft
