Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result
x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7
x=4, y=28, 28=k(4), k=7
The constant of proportionality is 7; we check 2×7=14, 11×7=77
Answer: k=7, y=7x
Answer: There are 2.25×10³⁴ bacteria at the end of 24 hours.
Step-by-step explanation:
Since we have given that
Number of bacteria initially = 1
It triples in number every 20 minutes.
So, 
So, our equation becomes
We need to find the number of bacteria that it will contain at the end of 24 hours.
So, it becomes,
Hence, there are 2.25×10³⁴ bacteria at the end of 24 hours.
35 x .6 = 21 so there must be 21 people present to take a vote.
To solve this equation, you haveto use the percent equation, which is p=% times w. IN this equation, p represents the part, % represents the percent, w represents the whole. We know so far that the whole is a total of 200 people. We also know that only 154 people actually attented, which tells us that the part os 154. What we need to figure out is the percent. Let's fill in the equation:
p=% X w
154= a X 200. (over here, I replaced the percent with the variable 'a' to show that it is unknown.)
154=200a
(Now, we isolate the variable.)
154/200=200a/200 ( We divide both sides by 200 to get the a alone.)
.77=a
We now know that our percent in decimal form is .77
After converting it to percent form, we get 77%
To rephrase:
77% of the invited guests attended the wedding. ( 154=.77x200 )
:) Hope this helped! Plz pick me as brainliest!
B. unlikely event
The chance of this happening is very unlikely not impossible.
