If you mean the system between the two then comes (x;y)=(5;3) otherwise if solved individually they are enough to make the common denominator

Simplify:2 1/3(4 1/4÷2)

kondor19780726 [428]

Answer:

$4\frac{23}{24}$

Step-by-step explanation:

We want to simplify:

$2\frac{1}{3}(4\frac{1}{4}\div 2)$

We convert to improper fraction to get:

$\frac{7}{3}(\frac{17}{4}\div 2)$

We now deal with the parenthesis by multiplying with the reciprocal of 2.

$\frac{7}{3}(\frac{17}{4}\times \frac{1}{2} )$

This gives:

$\frac{7}{3}(\frac{17}{8})$

We multiply to get:

$\frac{7}{3}(\frac{17}{8})$

This simplfies to:

$\frac{119}{24}$

We write as mixed number

$4\frac{23}{24}$

A 20 foot ladder is leaning up against the side of a house the distance between the house and the base of the ladder is 4 feet f

Pie

Answer:

78.5°

Step-by-step explanation:

We solve for the above question, using the formula for the Trigonometric function of Cosine

cos θ = Adjacent/Hypotenuse

Adjacent = The distance between the house and the base of the ladder = 4 feet

Hypotenuse = Length of the Ladder = 20 feet

Hence,

cos θ = 4/20

θ = arc cos(4/20)

θ = 78.463040967°

Approximately = 78.5°

Therefore, the angle that the ladder makes with the ground is 78.5°
