Get the x variable on one side and the numbers another side.

9/10(x + 2/3) = 4 1/2

Distribute the 9/10 across the x and 2/3.

(9/10)x + 18/30 = 4 1/2

Simplify 18/30 to make our life easier.

(9/10)x + 3/5 = 4 1/2

Subtract 3/5 from each side of the equation.

(9/10)x = 3 9/10

Divide both sides by 9/10.

x = 4 1/3

According to the Americans with Disabilities Act, a ramp can rise no more than 1 ft for every 12 ft of horizontal distance. What

taurus [48]

Answer:

A. 4.8°

Step-by-step explanation:

We have that,

The horizontal distance for the ramp = 12 feet.

Maximum height of the ramp = 1 feet.

So, we get that the value of the angle 'x' made by the ramp with the ground is given by,

$\tan x=\frac{perpendicular}{base}$

i.e. $\tan x=\frac{1}{12}$

i.e. $\tan x=0.0833$

i.e. $x=\arctan 0.0833$

i.e. x = 4.8°

Thus, the maximum angle made by the ramp with the ground is 4.8°.

At a certain time of day, the angle of elevation is 40°. To the nearest foot, find the height of a tree whose shadow is 31 feet

elena-s [515]

Answer: Height of tree = 26 ft

Make a triangle ABC with 40 degrees angle. The shadow is the base of the triangle equals 31 feet.

Base = AC = 31

Perpendicular = CB = ?

Hypotenuse = AB

Using trigonometric equation

tan 40 (deg) = CB / AC

CB = Tan 40 x AC

CB = 0.83909 x 31

CB = 26.011

Thus the height of the tree = 26 ft

WILL GIVE BRAINLIEST HELP!!

Lera25 [3.4K]

Answer is : $\sqrt[4]{5}$

Explanation:
$\frac{ \sqrt[4]{400}}{ \sqrt[4]{5}} = \frac{ \sqrt[4]{4*5*5*2*2} }{\sqrt[4]{5}}$

= $\frac{\sqrt[4]{5*5*2*2*4}}{\sqrt[4]{5}} = \sqrt[4]{5*2*2*4}$

= $\sqrt[4]{5*2*2*4} = \sqrt[4]{80}$
= $\sqrt[4]{2*2*2*2*5}$
= $\sqrt[4]{2^{4}} \sqrt[4]{5}$
= $\sqrt[4]{5}$
