A red horse and a black horse raced on a 1-mile-long circular racetrack. The red horse completed the race in 120 seconds, and the black horse completed the race in 150 seconds. Which choice correctly describes the speed of the horses?

The speed of red horse = 44 feet per second and the speed of black horse = 35.2 feet per second.

Step-by-step explanation:

Given: A red horse and a black horse raced on a 1-mile-long circular racetrack.

Time taken by red horse = 120 seconds

Time taken by black horse = 150 seconds

Speed =

So, speed of red horse =

Since 1 mile = 5280 feet

Speed of red horse =

Similarly,

Speed of black horse =

Hence, the speed of red horse = 44 feet per second and the speed of black horse = 35.2 feet per second.

the answer is 375 miles

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
