Answer:

Total cost = ($8.50b) + ($3.99d)

Step-by-step explanation:

In a bakery, the cost of a dozen bagels = $8.50

and the cost of a dozen donuts = $3.99

1 Dozen = 12 pieces

Let 'b' represents the number of bagels (in dozen) and d represents dozen donuts.

The expression that represents total cost of b dozen bagels and d dozen donuts would be :

Total cost = ($8.50b) + ($3.99d)

4.80

which means that :

The cost of

3

1.80

Therefore the cost for

1

0.60

The basic fee for hiring the cab is  

$

3.00

Answer:

4372 people would have been sick over time.

Step-by-step explanation:

Since the vaccine would be found in a week, then the over time is a week (7 days). Each day, a sick person infects two additional people.

Number of people infected by Velma can be predicted as follows:

Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458

Number of people infected by Velma = 1458 + 486 + 162 + 54 + 18 + 6 + 2

                                                       = 2186

Also, number of people infected by Stanley can be predicted as follows:

Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458

Number of people infected by Stanley = 1458 + 486 + 162 + 54 + 18 + 6 + 2

                                                       = 2186

Total number of people than can be infected over time = 2186 + 2186

                                                      = 4372

Therefore, the predictable number of infected people over time would be 4372. All citizens of Parsnipville would have been infected before the vaccine is available.

Answer:

Step-by-step explanation:

ASSUMING that only 4 new people get sick a day then we would have the equation 4x+2

The solution is,  : The figure shows a line tangent to the circle is, 4th figure.

As we know that, a tangent can be mentioned as a line segment to a circle which intersect the circle at exactly one point and that point is a tangency point.

here, we have,

the given figures,

we have to find the line  that is tangent to the circle.

we know that,

a tangent is a line segment to a circle which intersect the circle at exactly one point and that point is a tangency point.

And the radius from the center of the circle to the point of tangent is always perpendicular to the tangent line.

now, from this figures we get,

From this we conclude that, 4th figure is a right angled triangle that means the radius from the center of the circle to the point of tangent is always perpendicular to the tangent line.

Hence, The figure shows a line tangent to the circle is, 4th figure.

Step-by-step explanation:

If the fish are closser to the suface it will be closer to 0 on the number line.

A fish finder is an instrument on a boat that indicates that fish are located in a radius of -20 to 0.

Given that,
A fish finder is an instrument on a boat that indicates where fish are located. The range of the fishfinder is to be specified.

Range, it is the set of the values that come out to an outcome for certain mathematical operations.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
The range usual range of the fishfinder is standardly 0 to -20 on the number line of the instrument, where the negative sign indicates the depth.

Thus, A fish finder is an instrument on a boat that indicates that fish are located in a radius of -20 to 0.

Instructions are below.

Step-by-step explanation:

Giving the following information:

She must pay $200 to rent a booth at the craft fair. The materials for each pendant cost $7.80, and she plans to sell each pendant for $13.50.

We weren't provided with questions to answer. But, I will assume that we need to determine the number of units to be sold to break-even.

To calculate the break-even point in units and dollars, we need to use the following formulas:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 200 / (13.5 - 7.8)

Break-even point in units= 35 units

Break-even point (dollars)= fixed costs/ contribution margin ratio

Break-even point (dollars)= 200 / (5.7/13.5)

Break-even point (dollars)= $473.68

If you want to reach a certain profit:

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio
