Answer:
Lisa will not be able to feed both tanks the same amount of food.
Step-by-step explanation:
This question is incomplete, here is the complete question :
"Lisa pet shop has 2 fish tank . Tank A contains smaller fish who were fed 1 gram of food each per day. Tank B contains larger fish who are fed 2 gram each per day. If tank B contains 2/3 the number of fish Tank A contains,will Lisa ever feed both tanks the same amount of food."
Let the number of fish in tank A = f
Lisa fed 1 gram of food each per day = f × 1 = f
So,the number of fish in tank B = 
Lisa fed 2 gram of food each per day = 
If both the tanks are fed with same amount of food then
⇒ 3f = 4f
⇒ 3 = 4
But 3 ≠ 4
Therefore, Lisa will not be able to feed both tanks the same amount of food.
Answer:
A power function is a function that can be represented in the form
where k and p are real numbers, and k is known as the coefficient.
Example:
f(x)=1 constant function.
f(x)=x identity function
f(x)=x^2 quadratic function.
1)
we use the method of differences, g(x+1)-g(x). Keep taking differences until they are all constant.
for example:
if we have a set of values as:
x g(x)
−2 −8
−1 −1
0 0
1 1
2 8
Now when we find the difference as:
<u>x</u> <u>g(x)</u> <u> D1 </u> <u> D2 </u> <u> D3</u>
-2 -8
-1 -1 1-(-8)=7
0 0 0-(-1)=1 1-7=-6
1 1 1-0 = 1 1-1=0 0-(-6)=6
2 8 8-1 = 7 7-1=6 6-0 = 6
As D3 is constant hence, the degree of the power function is 3.
2)
When we get a constant difference in the table of the difference method we will successfully get our degree.
Step-by-step explanation:
well, it is supposed to be -3.
but you are right. something is wrong or missing here.
5x + 3 = 4x
x + 3 = 0
x = -3
maybe a "+ 1" is missing on the right side ?
5x + 3 = 4x + 1
gives us
x = -2
Answer:
Step-by-step explanation:
For example,
<u>Solution: Finding a unit rate</u>
If we divide 150 by 20, we get the unit rate for the ratio, 150 minutes for every 20 miles.
150÷20=7.5
So the runner is running 7.5 minutes per mile. We can multiply this unit rate by the number of miles:
7.5 minutes mile × 6 miles = 45 minutes
Thus it will take her 45 minutes to run 6 miles at this pace.
If it takes her 45 minutes to run 6 miles, it will take her 45÷3=15 minutes to run 6÷3=2 miles at the same pace.
If it takes her 15 minutes to run 2 miles, it will take her 4×15=60 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.
We found her pace in minutes per miles in part (a).
Answer:
It took him 12 hours
