The endpoints of the diameter of a circle are (-7,3) and (5,1) . What is the center of the circle

Answers

Answer 1
Answer:

Answer:

The center is the point (-1,2)

Step-by-step explanation:

we know that

The center of the circle is equal to the midpoint of the endpoints of the diameter

so

The formula to calculate the midpoint between two points is equal to

M((x1+x2)/(2),(y1+y2)/(2))

substitute the values

M((-7+5)/(2),(3+1)/(2))

M((-2)/(2),(4)/(2))

M(-1,2)

therefore

The center is the point (-1,2)

an ostritch can run at a rate of 50 miles in 60 minuites. how long would it take an ostrich to run 15 mikes

Answers

50 miles ... 60 minutes
15 miles ... minutes

If you would like to know how long would it take an ostrich to run 15 miles, you can calculate this using the following steps:

50 * x = 15 * 60
50 * x = 900    /50
x = 900 / 50
x = 18 minutes

Result: An ostrich can run 15 miles in 18 minutes.
\sf(50~miles)/(60~minutes) = (15~ miles)/(x~minutes)\n\n50(x) = 15(60)\n\n50x = 900\n\nx = 18

Your answer is 18 minutes

Why can't you compare 5 minutes in 240 seconds without making some kind of change

Answers

you have to have the same unit of measure. Here your units are "minutes" and "seconds". In order to compare the two, you must change to 240 seconds into minutes (dividing by 60 = 4 mins) OR change the 5 minutes into seconds (multiply by 60 to give you 300 seconds)

Which expression is equivalent to (3x - 5 y) + (x + 2 y)?A) 4x - 7y

D) 4x + 7y

Answers

Answer:

B) 4x - 3y

Step-by-step explanation:

(3x - 5 y) + (x + 2 y) \n \n = 3x + x + 2y - 5y \n \n = 4x - 3y
