Answer:

2

Another way to write this is:

20 ÷ 10

Answer: 2

This question is asking you to divide 20 by 10. This means:

20 ÷ 10=2

If 10 can go into a number 2 times, it means that 10•2=20. So, since we dont know how many times 10 goes into 20, we divide 20 by 10.

Below I have attached an image of the long division in case you need to do that as well.

Hope this helps comment below for more questions :)

Maria drove to a business appointment at 50mph in the morning. Her average speed on the return trip in the afternoon was 40 mph.
MakcuM [25]

Answer:

Distance to appointment point = 5 miles

Step-by-step explanation:

Let s be the distance to the appointment point,

We have Maria drove to a business appointment at 50mph in the morning.

Time taken in the morning

               t_m=\frac{s}{50}=0.02s

Her average speed on the return trip in the afternoon was 40 mph.

Time taken in the afternoon

               t_a=\frac{s}{40}=0.025s

Given that the return trip took 1/4hr longer because of traffic.

That is

             t_a-t_m=\frac{1}{4}hr=0.025hr

Substituting

             t_a-t_m=0.025hr\\\\0.025s-0.02s=0.025\\\\s=5miles

Distance to appointment point = 5 miles

Find the center, vertices, and foci of the ellipse with equation x squared divided by four hundred plus y squared divided by two
vivado [14]
To solve this problem you must apply the proccedure shown below:

 1. You have that the equation of the ellipse is the following:

 (x²/400)+(y²/256)=1

 2. You have that: 

 ((x-0)²/400)+((y-0)²/256)=1

 3. Then, the center is: 

 (0,0)

 4. The vertices are:

 a²=400
 a=√400
 a=20

 (-20,0)
 (20,0)

 b²=256
 b=√256
 b=16

 (0,-16)
 (0,16)

 5. The focci is:

 a²–c²=b²
 √(400-256)=c
 c=12

 (-12,0)
 (12,0)
