Answer:

Step-by-step explanation:

Number of individuals = 4

Cost of dozen donuts with transport = $17.45 + $1.25

= $18.7

Since there are 12 pieces in a dozen pack of donuts, then the amount of each donut is:

= $18.7/ 12

= $1.56

So, if four people share a dozen donut, each person will have:

= 12/4

= 3 donuts each

and the price each person will pay for the three donuts will be:

= $1.56 × 3

= $4.68

Answer:

3.74 x 10^5

Step-by-step explanation:

First expand the term in scientific notation into normal notation.

3.3 x 10^5   -   Here the ^5 tells us to move the decimal five places to the right, so we go from

3.30000 to

330000.00

So 3.3 x 10^5 = 330,000

Now add that to 44,000 and you get 374,000.

Return this number to scientific notation.  Move the decimal back to its spot before the 3.  We go from

374,000.00 to

3.74000

Once again the decimal has moved five places, so that is the number in the exponent of the our scientific notation, and therefore our answer is

3.74 x 10^5

Answer:

$20,000 = sales

Step-by-step explanation:

Giving the following information:

Fixed salary= $300

Commission rate= 1% of sales

First, we need to establish the net income formula:

Net income= 300 + 0.01*sales

Now, the sales required for $500 net income:

500= 300 + 0.01sales

200/0.01 = sales

20,000 = sales

Prove:

Net income= 300 + 0.01*20,000

Net income= $500

Step-by-step explanation:

The number comes to a stop (doesn't keep going), so it would be rational.

Answer:

3.5 is a rational number

Step-by-step explanation:

Irrational numbers are numbers that keep on going forever like pi (π). Or numbers like these.....[tex]\sqrt{72} , \sqrt{2} , \sqrt{\frac{8}{23} }[/tex]

Those are non-recurring numbers and non-terminating decimal numbers

Rational numbers are numbers that can be written as a simple fraction or ration, and 3.5 can be written as a simple fraction...

7/2 = improper fraction (3.5 as a decimal)

3 1/2 = mixed number (3.5 as a decimal)

Step-by-step explanation: To solve for X, we'll need to move all terms that don't contain X to the right and solve.

1. Add 16 to both sides

30x - 16 + 16 = 14 + 16

30x = 30

2. Divide both sides by 30

[tex]\frac{30x}{30} =\frac{30}{30}[/tex]

Answer:

(h,k) shows the coordintes of the turning point.

Answer:

coordinates of the vertex

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

f(x) = 3(x - h)² + k ← is in vertex form

with vertex = (h, k )

Answer:

1 i.e. n

Step-by-step explanation:

- linear pairs are supplementary, meaning they add up to 180°

5x + 9 + 3x + 11 = 180

8x + 20 = 180

8x = 160

x = 20

- now plug in.

angle 1: 5(20) + 9 = 100 + 9 = 109°

angle 2: 3(20) + 11 = 60 + 11 = 71°
