Answer:

y = 4/3

Step-by-step explanation:

The two equations can be added to eliminate x:

(0.1x +0.5y) + (-0.1x -0.2y) + (1.2) +(-0.8)

0.3y = 0.4 . . . . . simplify

Divide by the coefficient of y to find y:

y = 0.4/0.3

y = 4/3

Answer:

Answer attached: (-2 , 4)

Step-by-step explanation:

y=1/2x + 5

y= -5/2x -1

1/2x + 5 = -5/2x -1

3x = -6

x = -2

y = 1/2 x -2 + 5 = 4

U didn't mess up....
V = pi * r^2 * h....divide both sides by (pi)r^2
V / (pi)r^2 = h

A 25-foot long ladder is propped against a wall at an angle of 18° with the wall. how high up the wall does the ladder reach? ro

Alecsey [184]

Answer

Find out the how high up the wall does the ladder reach .

To proof

let us assume that the height of the wall be x .

As given

A 25-foot long ladder is propped against a wall at an angle of 18° .

as shown in the diagram given below

By using the trignometric identity

$cos\theta = \frac{Base}{Hypotenuse}$

now

$\theta = 18^{\circ}$

Base = wall height = x

Hypotenuse = 25 foot

Put in the trignometric identity

$cos18^{\circ} = \frac{x}{25}$

$cos18^{\circ} = \bar{0.9510565162}$

x = 23.8 foot ( approx)

Therefore the height of the ladder be 23.8 foot ( approx) .
