Answer: yeah I’m positive
Step-by-step explanation:
Answer:
-15, -17
Step-by-step explanation:
x^2 + 32x = –255 move the -255 to the left
x^2 + 32x +255=0
What two number when multiplied equal 255? Those same two numbers when added make 32. 17*15 make 255 and added is 32
(x+15)(x+17) For x+15=0 move the 15 to the other side. x= -15. Same with x+17=0 is x= -17
x= -15, -17
In the case of bacteria, we use the continuous growth equation:
Final=Initial×e∧(r×t)
In other words, the final amount is equal to the initial amount times e to the rate times time. In order to find your rate, you would plug in the numbers as follows:
3600=3000×e∧(6r)
Therefore: r=0.03
Next, you would plug in the r value and 13 hours into the equation to solve for the final amount.
F=3000×e∧(13×0.03)=4,453 bactera after 13 hours
23.1/7= 3.3, So by this way we recognized that the small figure is 3.3 times smaller than big figure.
Answer:
61 bikes are not mountain bikes.
Step-by-step explanation:
To figure this out you have to simply subtract the amount of mountain bikes from the total amount of bikes.
98 - 37 = 61
Now you know that 61 of the bikes are not mountain bikes.
I hope this helped! :)
