If Tori has 100 apples, and Peppa has 200, Alex had 300, and Lorenzo has 3 times the amount they did combined, How many apples does Lorenzo have?

Answer:

The complete question seems to be:

A doctor sees between 7 and 12 patients each day.

On Mondays and Tuesdays, the appointment times are 15 minutes.

On Wednesdays and Thursdays, they are 30 minutes.

On Fridays, they are one hour long.

The doctor works for no more than 8 hours a day.

Here are some inequalities that represent this situation.

0.25 ≤ y ≤ 1

7 ≤ x ≤ 12

xy ≤ 8

What represents each variable?

7 ≤ x ≤ 12

We know that the doctor sees between 7 and 12 patients each day, and the smallest value of x is 7, and the largest is 12, then x must represent the number of patients that the doctors see in a given day.

0.25 ≤ y ≤ 1

now,

On Mondays and Tuesdays, each appointment is 15 minutes long.

An hour has 60 minutes.

Then 15 minutes = 15/60 hours = 0.25 hours.

On Wednesdays and Thursdays, they are 30 minutes.

30 minutes = 30/60 hours = 0.5 hours.

Then the possible value of the time for each appointment are {0.25, 0.5, 1}

Then the variable y must represent the time that each appointment takes.

xy ≤ 8

We know that:

x =  number of patients in a given day.

y = time that the appointment takes in a given day.

x*y = total number of hours that he works in that given day.

and we know that he works, at maximum, 8 hours.

then the inequality xy ≤ 8 has sense.

Answer:

A:

2(x + 2) + 2(2x - 5) =

2x + 4 + 4x - 10 =

6x - 6

perimeter = 6x - 6

B:

(x+2)(2x - 5)            expand the brackets:

2x² - 5x + 4x - 10

area = 2x² - x - 10

C:

area = 6x - 6 = (6 x 5) - 6 = 30 - 6 = 24

perimeter = 2x² - x - 10 = (2 x 5²) - 5 - 10 = (2 x 25) - 5 - 10 = 50 - 5 - 10 = 35

Step-by-step explanation:

if you estimate all of these you get 3,7, and 7, these(added together) are 17,

Answer:

rate of change formula is (y2-y1)/(x2-x1)

so (36-24)/(7.5-5)= 12/2.5=4.8lbs

So for every 4.8lbs you give an extra mL of dosage

Answer: A) rate of change formula is (y2-y1)/(x2-x1)

so (36-24)/(7.5-5)= 12/2.5=4.8lbs.

Answer:

4.66 x 10^9

Step-by-step explanation:

The performance of the computer in one minute is 2.70x10¹⁰ per minute after performing unit conversion.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that:

A computer can perform 4.66 x 10⁸ calculations per second,

As we know,

1 minute = 60 seconds

1 second = 1/60 minutes

The performance of the computer in one minute = 4.66 x 10⁸(1/(1/60))

The performance of the computer in one minute = 4.66x60x 10⁸

The performance of the computer in one minute = 279.6x10⁸

= 2.70x10¹⁰ per minute

Thus, the performance of the computer in one minute is 2.70x10¹⁰ per minute after performing unit conversion.

Since she earns $180 in 18 hours, she earns a rate of $ 180/18 per hour, which is $10 per hour.

In 30 hours she earns 30 times 10 dollars, which is 300 dollars.

You could also set up a proportion saying that 180/18 = x/30, then cross multiply to get 18x = 5400, and divide by 18 on both sides to get 300.

Answer:

-25

Step-by-step explanation:

g(f(3))= g(-5)

=4(-5)-5

= -20-5

=-25

Answer:

[tex]g(f(3))=-25[/tex]

Step-by-step explanation:

We have the two functions: [tex]f(x)=-2x+1[/tex] and [tex]g(x)=4x-5[/tex].

And we want to evaluate [tex]g(f(3))[/tex].

So, let's evaluate f(3) first. Substitute 3 into f(x). This yields:

[tex]f(3)=-2(3)+1[/tex]

Multiply and add:

[tex]f(3)=-6+1=-5[/tex]

So, our expression is now:

[tex]g(f(3))\Rightarrow g(-5)[/tex]

Substitute -5 for g(x):

[tex]g(-5)=4(-5)-5[/tex]

Multiply and subtract:

[tex]g(-5)=-20-5=-25[/tex]

Therefore:

[tex]g(f(3))=-25[/tex]

Answer:

C. P(x) = -0.6x3 + 300x^2 – 700x + 600

Step-by-step explanation:

The profit function is P(x) = -0.6x³ + 300x² - 700x + 600.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given,

Cost function, C(x) = 500x² + 400x

Revenue function, R(x) = -0.6x³ + 800x² - 300x + 600

Profit is the difference between the revenue and the cost.

Profit function is therefore the difference of revenue function and the cost function.

P(x) = R(x) - C(x)

P(x) = (-0.6x³ + 800x² - 300x + 600) - (500x² + 400x)

      = -0.6x³ + 800x² - 300x + 600 - 500x² - 400x

      = (-0.6x³) + (800x² - 500x²) + ( - 300x - 400x) + 600

      = -0.6x³ + 300x² - 700x + 600

Hence the profit function of the granola bar company is P(x) = -0.6x³ + 300x² - 700x + 600.
