Using Gauss's method
Total number of terms = [15-(-129)]/4+1=36+1=37
Add
S=15+11+7+....-125-129
S=-129-125-...+7+11+15
--------------------------------
2S=-114-114-114...(37 times)
=>
sum=S=(1/2)*(-114)*37=-2109
Using AP, T(n)=15+11+7+....-129
T(n)=19-4n => T(1)=15, T(37)=-129
S(n)=(1/2)(37)(T(1)+T(37)=(1/2)37(15-129)=2109
If you divide 67 by 50 you are left with 1.34 if you turn that decimal into a percent it turns into 134%
Domain is the values of y.
Plug the x values in the equation to find the corresponding y values:
when x=0, y=3
when x=2, y=-1
when x=-6, y=15
so the answer is D
Answer:
No, she is not correct as her speed is 0.25 miles per minute.
Step-by-step explanation:
Given:
Ratio of distance to time taken is 15 : 60.
Distance is in miles and length of time is in minutes.
We know that, average speed is given as the ratio of the distance traveled and the length of the time taken.
So, the ratio above is nothing but the average speed of Reese for cycling.
Thus, average speed of Reese is given as:
Therefore, the average speed of Reese is 0.25 miles per minute which is not equal to the one mentioned by Reese as 4 miles per minute.
So, Reese conclusion of her average speed is incorrect. It's not 4 but the reciprocal of 4 which is 0.25 miles per minute.
Answer:
the answer is c for Friday and 6 3/12 hours for them both combined
Step-by-step explanation:
because 3 5/12 is closest to 3 1/2=3 6/12
for fir day and Saturday day combined it would be 6 3/12
because 5/6 is 10/12 and 5/12 + 10/12 is 15/12 which is also 1 3/12
so add 3 +2=5 and then add the fraction 1 3/12 which would be 6 3/12 hours
