Rafe and Sebastian both rode in a 5 mile bike race. There were so many riders that they started groups at different times. Rafe

started the race at 3:30 PM and finished the race at 4:00 PM. Sebastian started the race at 4:25 PM and finished at 4:53 PM. What was the speed, in miles per hour, of the boy who rode at a faster rate? Round to the nearest tenth if necessary.

Answer:

10.7 miles/hour

Step-by-step explanation:

So let's first write all the known for the question

total race = 5 mile

Rafe time 3:30~4:00pm

Sebastian time 4:25~4:53 pm

Then let's find out how much time rafe and sebastian took for races in hours and who took less time(who's faster)

Rafe time 30 min = 0.5 hours

Sebastian time 28 min = 0.467 hours

0.467 < 0.5 hours

-Hence Sebastian had faster speed.

Now let's calculate the speed of Sebastian

5 mile/0.467 hours= 10.714

Round to nearest tenth

10.7 miles/hour

PLEASE HELPPP!!! Which expression is equivalent to sum of quantity negative three and one third times n plus one sixth end quant
uranmaximum [27]

The given expression is equivalent to the expression - 11/6 n - 1/12. Then the correct option is C.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The sum of capacity minus three and one-third times n plus one-sixth ended capacity + capacity one and three-sixths times n minus three-twelfths end quantity.

Let n be the number. Then the expression will be

⇒ -(3  1/3)n + 1/6 + (1  3/6)n - 3/12

Simplify the equation, then we have

⇒ -(3  1/3)n + 1/6 + (1  3/6)n - 3/12

⇒ -10/3 n + 3/2 n + 1/6 - 1/4

⇒ -11/6 n - 1/12

The given expression is equivalent to the expression - 11/6 n - 1/12. Then the correct option is C.

Please help! double points. thanks

Check the picture below.

so, hmmm notice, since i² = -1 and i⁴ = 1, whenever the exponent is only divisible by 2, the value will be -1, and whenever the exponent is divisible by 4, we end up with a +1, so every subsequent even exponent is simply cancelling the previous value, if we take that to the even value of 100, which has 50 pairs of those, we end up with, yeap, you guessed it, 0.

The equation x^2+y^2-4x+27=b
Gala2k [10]
X^2 + y^2 -4x27 (the numbers in bold means the multiplying a negative and a positive equals a negative)

x^2 + y^2 -(4x27) = x^2 + y^2 -108
