heather is a hairdresser and her customers pay $5 to reserve an appointment time and $12 for every hour heather works on their hair style.as back to school special she offers to lower her price per hour by $5 what equation represents the total amount paid to heather,y,after x hours of hair styling

Answers

Answer:

y = 5 + 7x

Step-by-step explanation:

So 5 is going to be a constant factor. So Y is gonna equal 5 plus something. 12 dollars for every hour is 12x and there is a 5 dollar discount. 12-5 = 7 and so it is 7 dollars per hour.

So the total cost Y equal the constant 5 and 7x

Y = 5 + 7x

Solve the following system: y = x 3 3x y = 19 (7, 4) (â’4, 7) (4, 7) (4, â’7).

Answers

The correct option is C. (4,7).

Given equations,

[tex]y=x+3....(1)\\3x+y=19....(2)[/tex]

We have to solve the equations.

From equation 1 put the value of y in equation 2 we get,

[tex]3x+x+3=19\\4x=16\\x=4\\[/tex]

Now putting the value of x in equation 1 we get,

[tex]y=4+3\\y=7[/tex]

Hence the required solution of the above equations is (4,7).

what is the answer -v+91=261

Answers

Answer:

v = -170

Step-by-step explanation:

-v + 91 = 261

(-v + 91) - 91 = 261 - 91

-v = 170

-v / -1 = 170 / -1

v = -170

Step-by-step explanation:

(-v) +91 = 261

(-v) =91=261

(-v)=261-91

(-v)=170

v= - 170 (change the signs)

Angle a and angle b are supplementary angles. if measure angle A=(2x-14)degree and m angle B= (3x-6) degree, then find measure of angle A

Answers

we have: ∠A + ∠B = 90°

<=> (2x-14) + (3x-6) = 90° <=> 2x - 14 + 3x - 6 = 90°

<=> 5x + 20 = 90°

<=> 5x = 70°

<=> x = 14°

So: ∠A = 2x - 14 = 2.14 - 14 = 14°

need help on this I need all work shown as well, the subject is on similar triangles

Answers

Answer:

10 in

Step-by-step explanation:

If you draw a line parallel to the side of the cone through the center of the 10-inch (radius) circle, you create a right triangle with one leg 10 inches and a hypotenuse of 20+10 = 30 inches. It is similar to the right triangle shown on the diagram with leg 10 inches. That means the distance from the center of the 10-inch (radius) ball to the bottom of the cone is 30 inches.

Subtract from that the 10-inch radius and the 10-inch diameter of the two bottom balls shown, and you find the distance from the base of the smallest ball to the bottom of the cone is 30 -10 -10 = 10 inches.

Answers

Answer:

Step-by-step explanation:

Given is a degree in decimals as 55.27 degrees

But normally in degrees, we use for part of degrees minutes and seconds

60 seconds make one minute and 60 minutes make one degree.

Here 55 degrees would be the same

But part degree 0.27 = 27/100

If we want to convert this into minutes multiply by 60

No of minutes =
