Answer:
C. 16 cm
Step-by-step explanation:
Top side: 2 + 4 = 6
Right side: 1 + 1 = 2
Bottom: 2 + 4 = 6
Left side: 1 + 1 = 2
6+6+2+2 = 16 cm.
Rewrite 2x^2+x=15 as <span>2x^2+ x - 15 = 0. Use your favorite method to solve this for x. I prefer synthetic div., so will check out whether or not 2 is a root:
____________
2 / 2 1 -15
4 10
---------------------
2 5 -5 Since there is a non-zero remainder, 2 is NOT a root. Eliminate the 3rd answer choice.
Try -3. If used as a divisor in synth. div., will the remainder be zero or not zero? If zero, then -3 is a solution / root.
And so on.</span>
Answer:
B is your answer,
With the factors of ( 2 )( 1 ), the lay out of the equation makes only sense with answer B.
Answer:
Average speed of go cart is 217.07 meters per minute.
Step-by-step explanation:
We are given the following in the question:
Length of straightway racetrack = 100 m
Diameter of semicircular end = 40 m
Radius =
Perimeter of racetrack =
Perimeter of semicircle + 2(Length of straightway) + Perimeter of semicircle
Speed =
Thus, average speed of go cart is 217.07 meters per minute.
