Answer:

237

Step-by-step explanation:

Answer:

110, 130, 140

Step-by-step explanation:

The x-values are the elements of the domain.

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:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the distance between the line which formed like :

[tex]ax + by + c = 0[/tex]

and the point which is like :

[tex]h = \binom{m}{n} \\ [/tex]

we use following equation :

[tex]d = \frac{ |a(m) + b(n) + c| }{ \sqrt{ {a}^{2} + {b}^{2} } } \\ [/tex]

_________________________________ Step (2)

[tex]y = - x + 4[/tex]

[tex]x + y - 4 = 0[/tex]

So ;

[tex]a = 1[/tex]

[tex]b = 1[/tex]

[tex]c = - 4[/tex]

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

A = ( 2 , - 1 )

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

So we have :

[tex]d = \frac{ | \: 1(2) + 1( - 1) - 4| }{ \sqrt{ {1}^{2} + {1}^{2} } } = \\ [/tex]

[tex]d = \frac{ |2 - 1 - 4| }{ \sqrt{1 + 1} } = \frac{ | - 3| }{ \sqrt{2} } \\ [/tex]

[tex]d = \frac{3}{ \sqrt{2} } \\ [/tex]

And we're done.

Thanks for watching buddy good luck.

Step-by-step explanation:

Total marbles: 20

Total Blue marbles: 5

Ratio is 5:20

Simplified ratio is 1/4

Answer: It's letter A, because it's slope-intercept form.

Step-by-step explanation:

Answer: -22.4

Step-by-step explanation:

If the numbers are correct and assuming the 8.9 is written as a decimal the answer is -22.4. If the 8 and 9 are multiplied than the answer is completely different.  

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:

Mabel will earn 300$ in 30 hours

Step-by-step explanation:

I took 180 and divided it by 18 so that I can find how much money she earns per hour.

180÷18= 10

10 × 30= 300

Answer:

D: Observational Study

Step-by-step explanation:

edg2020

He did not go around asking people how many of them buy lunch, so it is not a survey. He did not create the settings and conditions or simulate possible examples, so its not B. He did not control or change any variables, so it is not an experiment. He simply walked around and Observed people to get information for his study. Thus it is D.

Answer:

720

Step-by-step explanation:

Just multiply all the measurements together

10 times 8 times 9 equals 720

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:

8/15

Step-by-step explanation:

(2/5)/(3/4)

2*4=8

5*3=15

8/15

Answer:

[tex]\frac{8}{15}[/tex]

Step-by-step explanation:

[tex]\frac{2}{5}[/tex] ÷ [tex]\frac{3}{4}[/tex]    (convert division to multiplication by inverting the second fraction)

= [tex]\frac{2}{5}[/tex] × [tex]\frac{4}{3}[/tex]   (combine fractions by multiplying numerator with numerator and denominator by denominator)

= [tex]\frac{(2)(4)}{(5)(3)}[/tex]

= [tex]\frac{8}{15}[/tex]

Answer:

option b - 120+10x=18x

Step-by-step explanation:$120 is yearly and $10 is multiplied by x - how many times you want to rent

and then 18 is how much you pay for x times you want to rent it

Answer:

500,000

Step-by-step explanation:

2 · 10^15 = 2,000,000,000,000,000

4 · 10^9 = 4,000,000,000

2,000,000,000,000,000 divided by 4,000,000,000 = 500,000

Tip: When you're multiplying 10 to the power of any number, you can just add that amount of zeros to 1.

Example: 10^7

Answer: 10,000,000

There are seven zeros.

Answer:

The answer is "5 or 35".

Step-by-step explanation:

It also is important to understand the difference in the AP and PA predictions, and we will talk regarding their difference, and maybe we'll take the circumstances.

It is called the PA view during the process of x-ray and as the x-ray passes from its body back to both the foreground.

Its direction was its reverse throughout the AP view. Now let's understand what critical it's really. So less the distance among object and display was also created, much clears the shadow, and according to physics concepts x-ray was its light source in this instance, but we're the target. In AP display's the rear side, which means good shadow, whereas the implications of alternative give better shadow in the PA view.

If talking around the same picture, the angle difference between both the AP and the PA visual is maximum of 15-20°.

Its situation indicates a caudal angle of 20° for the AP test. So, it must be for PA:

[tex]\to 20(\pm) 15 \\\\\to 20+ 15 \ \ \ \ or \ \ \ \ \to 20-15 \\\\\to 35 \ \ \ \ or \ \ \ \ \to 5 \\\\[/tex]
