9514 1404 393

Answer:

  a) $3.45

  b) P(x) = 0.0003x -18

  c) $3.00, A

Step-by-step explanation:

a) When the family income is $71,500, it exceeds $70,000 by ...

  $71,500 -70,000 = $1500

Then the price of the child's lunch will be ...

  $3.00 + 0.0003×1500 = $3.45

__

b) For family income in the given range, the price of a lunch will be ...

  P(x) = 3.00 + 0.0003(x -70000) = 3.00 +0.0003x -21.00

  P(x) = 0.0003x -18.00

__

c) P(70000) = 0.0003×70000 -18 = 3×7-18 = 3.00

The definition of P(x) in part (b) tells you the meaning of this. x=70,000 is the family's annual income; P(x) is the price of a lunch.

  P(70,000) is the price of a lunch for a child whose family annual income is $70,000.

<h3>Hello There !! </h3>

<h3><u>Explanation :- </u></h3>

• Amount received by Rui = 5x = 5 x 11 = $55..

• Amount received by Vishal = 9x = 9 x 11 = $99..

Let the amount received by Rui be 5x..

Then the amount received by Vishal is 9x ..

And by this data = 5x + 44 = 9x ..

  • 4x = 44
  • x = 44/4 = 11

• Amount received by Rui = 5x = 5 x 11 = $55..

• Amount received by Vishal = 9x = 9 x 11 = $99..

The sum of the angle measures of any triangle is 180 degrees. Angle 2 is twice the measure of angle 1. Angle 3 is 15 degrees les
allochka39001 [22]

Answer:

Angle 1 = 39, Angle 2 = 78 , Angle 3 = 63

Step-by-step explanation:

78/2 = 39

(Angle 2/2 = Angle 1)

78 - 15 = 63

(Angle 2 - 15 = Angle 3)

39 + 78 + 63 = 180

(Angle 1 + Angle 2 + Angle 3 = 180)

What is the area of a semi circle that has a diameter of 1 1/2?
SVEN [57.7K]

Answer:

A=0.8836

Step-by-step explanation:

Area of circle:

\pi r^2

By using the area of a circle, we can get the area of a semicircle:

\frac{\pi r^2}{2}

Let's convert the mixed fraction to an improper fraction and then a decimal:

1\frac{1}{2} = \frac{3}{2} = 1.5

Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

\frac{1.5}{2} =0.75

Now we have the radius, so we can plug in our values and find the area:

\frac{\pi0.75^2}{2} = 0.88357293

A=0.88357293
