A meter is 100 cm. A ball of string has 10m of string, and you multiply 10m by 100cm, you get 1,000cm. Then you multiply 40cm by 2, and you get 80cm, or two lengths of string. Then you multiply 35, which is half of 70, by 80, and that is 2,800 cm.2,800÷40cm=70And 100cm=1m.The teacher will therefore need 28 balls of string.
Answer:
total number of tickets sold is 387
students tickets were two times that of adult which is 2x
adult is x
2x + x =387
3x=387
x=387/3
x=129
recall that adult is x
therefore adult is 129
to confirm the answer, remember that the student tickets sold is twice that of the adult. if adult is 129 then student ticket is 129 x2 which is 258 plus the number of adult ticket sold which is 129 the sum of the 258 and 129 is 387
Answer:
m+n should replace the question mark
Step-by-step explanation:
m+m = 2m
-n+n=0
Answer:
<u>The correct answer is D. There is no constant rate of change and hence it is a nonlinear function.</u>
Step-by-step explanation:
mph over speed limit 5 9 14 19 29
fine (dollars) 165 180 195 240 265
Let's calculate the rate of change, as follows:
For 9 mph over speed limit = (180 - 165)/(9 - 5) = 15/4 = 3.75
For 14 mph over speed limit = (195 - 180)/(14 - 9) = 15/5 = 3
For 19 mph over speed limit = (240 - 195)/(19 - 14) = 45/5 = 9
For 29 mph over speed limit = (265 - 240)/(29 - 19) = 25/10 = 2.5
As we can confirm there isn't a constant rate of change and in consequence, it's a nonlinear function.
<u>The correct answer is D. There is no constant rate of change and hence it is a nonlinear function.</u>
The total charges for the first club as a function of the number of rentals (x) are
... f1 = 25 + 2.50x
The total charges for the second club are
... f2 = 3.25x
We want to find x so that f1 < f2.
... f1 < f2
... 25 + 2.50x < 3.25x
.. 25 < 0.75x . . . . . . . . . . subtract 2.50x
... 25/0.75 < x . . . . . . . . . divide by the coefficient of x
... 33 1/3 < x
You must rent 34 videos or more to make the first club more economical.
