A doctor sees 210 patients every 3 weeks. At this rate, how many patients will the doctor see in 12 weeks?

Sav [38]

First you divide 12 by 3 to get 4, and then you multiply 210 by 4 to get 840, which is answer C. This is because if it is 210 patients per 3 weeks, 3 goes into 12 weeks 4 times, so you need to multiply. I hope this helps!

Two planes simultaneously left the Washington and LA and headed towards each other. The distance between the cities is 2700 mile

katrin2010 [14]

Answer:

Speed of the plane from Washington: $500\ mph$

Speed of the plane from LA: $600\ mph$

Step-by-step explanation:

We need to remember that:

$d=Vt$

Where "d" is distance, "V" is speed and "t" is time.

Let be "w" the speed in mph of the plane from Washington and "l" the speed in mph of the plane from LA.

We know that the distance between the cities is 2700 miles and after they flied for 2 hours, the distance between them was 500 miles. Then we can write the following equation:

$2w + 2l + 500 = 2700$ [Equation 1]

Since the speed of the plan from LA was 100 mph faster, we can write this equation:

$l=w+100$ [Equation 2]

The steps to solve this are:

1. Substitute the Equation 2 into the Equation 1 and solve for "w":

$2w + 2(w+100) + 500 = 2700\\\\4w+200+500=2700\\\\w=\frac{2000}{4}\\\\w=500$

2. Substitute the value of "w" into the Equation 2 in order to find "l":

$l=500+100\\\\l=600$

The volume of a cube is 64 cubic meters. What is the surface area of the cube, in square meters?

sergeinik [125]

Answer:

96 square meters

Step-by-step explanation:

Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.

We then find the area of one face which is 4 * 4 = 16 square meters.

We must then multiply this by the amount of sides on our cube which is 6.

16 * 6 = 96 square meters.

What is y + 11 = 1/3(x + 3) in standard form?

lorasvet [3.4K]

Standard form is y=Mx+b so first step is to isolate y:
Y=1/3(x+3)-11

Then use order of operations to simplify the x to a whole number. First multiply by three:
3y=x+3-33

Now combine like terms:
3y=x-30

Finally,
Divide to make y have a coefficient if one:

Y= 1/3x -10
