Answer:

The correct answer is B) y = 1/6x + 4

Step-by-step explanation:

Since the slope of the original line is -6, we are looking for a line with a slope of 1/6. This is because perpendicular lines have opposite and reciprocal slopes. B is the only answer that satisfies that situation.

Find the percent cost of the total spent on each equipment $36, fees $158, transportation $59
Evgen [1.6K]

Percent cost of the total spent on

each equipment = 14.23%,fees=62.45% and transportation = 23.32%.

As given in the question,

Money spent on

Each equipment = $36

Fees = $158

Transportation = $59

Total money spent = $( 36 + 158 + 59)

                             = $253

Percent cost of the total spent on

Each equipment = (36/253) × 100

                          = 14.23%

Fees = (36/253) × 100

        = 62.45%

Transportation =(36/253) × 100

                       = 23.32%

Therefore, percent cost of the total spent on

each equipment = 14.23%,fees=62.45% and transportation = 23.32%.

Find an equation of variation where y varies jointly as x and the square of z, and where y=70, when x=21 and z=5.
Bezzdna [24]

Answer:

y = 181.75xz^2

Step-by-step explanation:

Given

y jointly varies to x and z^2

Required

Find the equation

We start by writing out the variation;

y\ \alpha\ xz^2

Write as equation

y = kxz^2

Substitute values of x,y and z

70 = k * 21 * 25^2

70 = k * 21 * 25 * 25

70 = k * 13125

Divide both sides by 7

\frac{70}{13125} = \frac{k * 131251}{13125}

\frac{70}{13125} = k

187.5 = k

k = 181.75

Substitute k in y = kxz^2

y = 181.75xz^2

PQ is tangent to OR at point P. Find mZQ.<br> A. 17°<br> B. 27°<br> C. 63°<br> D. 73°
mamaluj [8]

Answer:

A

Step-by-step explanation:

The angle between the tangent PQ and the radius RP at the point of contact P is 90°

The sum of the 3 angles in Δ PQR = 180° , thus

∠ Q = 180° - (90 + 73)° = 180° - 163° = 17° → A
