A haircut is 20 sales tax is 4.75 is 25 sufficient to cover the haircut cost with tax n tip %15 tip

1 answer:

5 0

Percentage of tip that needs to be given for hair cut = 15%
Amount of tip is calculated without sales tax.
Amount taken for the hair cut = 20
Amount of sales tax taken = 4.75
Then
Amount of tip given = (15/100) * 20
= 300/100
= 3
So the total amount required for the hair cut = 20 + 4.75 + 3
= 27.75
So 25 is insufficient amount to cover the hair cut cost with tip and sales tax. The actual amount required to cover the total cost is 27.75<span />

Calculate pt3 such that a line from pt1 to pt3 is perpendicular to the line from pt1 to pt2, and the distance between pt1 and pt

Leni [432]

Let the point_1 = p₁ = (1,4)
and      point_2 = p₂ = (-2,1)
and      Point_3 = p₃ = (x,y)

The line from point_1 to point_2 is L₁ and has slope = m₁
The line from point_1 to point_3 is L₂ and has slope = m₂
m₁ = Δy/Δx = (1-4)/(-2-1) = 1
m₂ = Δy/Δx = (y-4)/(x-1)
L₁⊥L₂ ⇒⇒⇒⇒ m₁ * m₂ = -1
∴ (y-4)/(x-1) = -1 ⇒⇒⇒ (y-4)= -(x-1)
(y-4) = (1-x) ⇒⇒⇒⇒⇒⇒⇒⇒⇒⇒⇒⇒⇒⇒ equation (1)

The distance from point_1 to point_2 is d₁
The distance from point_1 to point_3 is d₂
d = $\sqrt{Δx^2+Δy^2}$
d₁ = $\sqrt{(-2-1)^2+(1-4)^2}$
d₂ = $\sqrt{(x-1)^2+(y-4)^2}$
d₁ = d₂
∴ $\sqrt{(-2-1)^2+(1-4)^2} = \sqrt{(x-1)^2+(y-4)^2}$ ⇒⇒ eliminating the root
∴(-2-1)²+(1-4)² = (x-1)²+(y-4)²
(x-1)²+(y-4)² = 18
from equatoin (1) y-4 = 1-x
∴(x-1)²+(1-x)² = 18            ⇒⇒⇒⇒⇒ note: (1-x)² = (x-1)²
2 (x-1)² = 18
(x-1)² = 9
x-1 = $\pm \sqrt{9} = \pm 3$
∴ x = 4 or x = -2
∴ y = 1 or y = 7

Point_3 = (4,1) or (-2,7)

You are driving on a highway and are about 55 miles from a state border. You set your cruise control at 60 miles per hour and pl

kumpel [21]

Based on your distance from the state border and the cruise control speed, the minimum and maximum hours you will have cruise control on is:

Minimum - 1/3 hours
Maximum - 1.5 hours

<h3>How long will cruise control be on?</h3>

You are 55 miles from the state border. You want to put the cruise control off within 35 miles of the border on either side.

This means that you might put it off in:

= 55 - 35

= 20 miles

The time to 20 miles is the minimum time the cruise control will be on:

= 20 miles / 60 miles per hour

= 1/3 hours

If you put it off 35 miles after the border, the distance is:

= 55 + 35

= 90 miles

The maximum time is:

= 90 / 60

= 1.5 hours

Complete the equation of the line through (−8,8), and (1,-10 ). Use exact numbers. Help me please my dog just died and I want to

katrin2010 [14]

Answer: (Mayadc821 wrote this anwser check theyre account for more)

Since you know the x and y values, you just have to plug these into the linear slope-intercept equation:

y = mx + b

-10 = m(1) + b

m + b = -10

b = -10 - m

Now that we have a value for b, we can plug this into the other equation:

8 = m(-8) + b

8 = -8m + (-10 - m)

8 = -9m -10

18 = -9m

m = -2

Now that we know what m is equal to, we can plug this into our first equation to get an answer for b:

b = -10 - m

b = -10 -(-2)

b = -10 + 2

b = -8

Our final equation is y = -2x - 8
