28 students travel on a field trip. They bring a van that can seat 12 students. Elena and Kiran's teacher asks parents to drive

cars that seat 3 children each to transport the rest of the students.
Elena wonders if she should use the inequality
12+3>28
12

or
12+3≥28

to figure out how many cars are needed. Kiran doesn't think it matters in this case. Solve the inequality to explain why Kiran is correct. (use / to represent fractional quantities and a space between whole numbers and the fraction. Example

Answer: Yes, you can use this inequality to find the numbers of cars required.

Step-by-step explanation:

12  + 3n > 28     where n = the number of cars required

3n > 28 -12

3n > 16

n > 5 1/3

Greater than 5 1/3 gives 6 cars.

Answer:

See below.

Step-by-step explanation:

12 + 3n ≥ 28

3n ≥ 16

n ≥ 5 1/3

The number of cars must be equal to or greater than 5 1/3.

Since there is no 1/3 of car, that means there must be 6 cars.

Whether the inequality is 12 + 3n > 28 with a solution of more than 5 1/5 or the inequality is 12 + 3n ≥ 28 with a solution of 5 1/3 or more, the answer is the same because the minimum number of cars that will be enough is 6.

Write an equation for a circle with a diameter that has endpoints at (–10, 1) and (–8, 5). Round to the nearest tenth if necessa
satela [25.4K]

The standard form for the equation of a circle is :

<span><span><span> (x−h)^</span>2</span>+<span><span>(y−k)^</span>2</span>=<span>r2</span></span><span> ----------- EQ(1)
</span><span> where </span><span>handk</span><span> are the </span><span>x and y</span><span> coordinates of the center of the circle and </span>r<span> is the radius.
</span> The center of the circle is the midpoint of the diameter.

 So the midpoint of the diameter with endpoints at (−10,1)and(−8,5) is :

 ((−10+(−8))/2,(1+5)/2)=(−9,3)

 So the point (−9,3) is the center of the circle.

  Now, use the distance formula to find the radius of the circle:

  r^2=(−10−(−9))^2+(1−3)^2=1+4=5

 ⇒r=√5

 Subtituting h=−9, k=3 and r=√5 into EQ(1) gives :

 (x+9)^2+(y−3)^2=5
