Answer:
To catch your friend you have to paddle for 1.25 hours
Step-by-step explanation:
Your friend is 0.5 mile in front of you and paddling 3 miles per hour. You are paddling 3.4 miles per hour.
Since the speed is the relationship between the space traveled by an object and the time used for it, then the distance is defined as:
distance= speed*time
Being x the time it takes to reach your friend, then your friend's position will be:
3miles per hour*x + 0.5 (since your friend is 0.5 mile in front of you)while your position is:
3.4 miles per hour*xWhen you reach your friend the position of both should be the same. So:
3*x + 0.5= 3.4*x
Solving:
0.5= 3.4*x - 3*x
0.5= 0.4*x
0.5 ÷0.4= x
1.25= x
This means that to catch your friend you have to paddle for 1.25 hours

Is the following relation a function?
Relation:
Х Y
6 8
5 1
6 6
2 4
The domain:
{2,5,6}
The range:
{1,4,6,8}
Answer: No
Step-by-step explanation:
The domain consists of the numbers 6, 5, 6, 2
6 is repeated twice
The criteria for a function is that there are no repeating numbers in the domain
This does not follow the criteria, therefore this is not a function

x = 8
happy holidays :)
please click the heart to give thanks :)
Step-by-step explanation:
STEP 1:
Equation at the end of step 1
(3x - 4)2 = 0
STEP 2:
Solving a Single Variable Equation:
2.1 Solve : (3x-4)2 = 0
(3x-4) 2 represents, in effect, a product of 2 terms which is equal to zero
For the product to be zero, at least one of these terms must be zero. Since all these terms are equal to each other, it actually means : 3x-4 = 0
Add 4 to both sides of the equation :
3x = 4
Divide both sides of the equation by 3:
x = 4/3 = 1.333
One solution was found :
x = 4/3 = 1.333

Step-by-step explanation:
The animal shelter had a special on adoption rates for their dogs and cats. Each dog adoption fee was $75 and each cat adoption fee was $35. On Christmas Eve, the animal adopted out 8 total animals and brought in $400 in total adoption fees. How many dogs and how many cats were adopted out on Christmas Eve?
dogs:
cats:
Answer:
3 dogs and 5 cats were adopted out on Christmas eve.
Step-by-step explanation:
Let the number of dogs adopted out on Christmas eve be x and the number of cats be y.
From the question,
On Christmas Eve, the animal adopted out 8 total animals
That is, x + y = 8 ...... (1)
and brought in $400 in total adoption fees.
Also from the question,
Each dog adoption fee was $75 and each cat adoption fee was $35.
∴ On Christmas Eve,
75x + 35y = 400 ...... (2)
Now, to determine how many dogs and how many cats were adopted out on Christmas Eve, we will solve the two equations simultaneously.
From equation (1)
x + y = 8
Make x the subject of the relation.
∴ x = 8 - y ...... (3)
Substitute the value of x into equation (2)
75(8 - y) + 35y = 400
600 - 75y + 35y = 400
600 -40y = 400
600 - 400 = 40y
200 = 40y
∴ 40y = 200
y = 200/40
y = 5
Substitute the value of y into equation (3)
x = 8 - y
x = 8 - 5
x = 3
∴ x = 3 and y = 5
Hence, 3 dogs and 5 cats were adopted out on Christmas eve.

Answer:
Domain → [-5, ∞)
Range → [-2, ∞)
Step-by-step explanation:
Domain:
Domain of a function on from its graph is represented by the set of x-values (Input values).
Range:
Range of a function is a set of y-values (output values).
From the graph attached,
Graph starts from x = -5 and tends towards the infinity, so the domain will be,
Domain → [-5, ∞)
Similarly, y-values vary from y = -2 to y = ∞
Therefore, Range → [-2, ∞)
Given the graph of the function:
Domain is: [-5, ∞)
Range is: [-2, ∞)
Domain and Range of a FunctionThe domain of a function are all the values of x that are plotted on the x-axis, while the corresponding y-values are the range of the function.
Thus:
From the given graph representing a function:
Domain of the function is between -5 to infinity.
Range of the function is between -2 to infinity.
Therefore, given the graph of the function:
Domain is: [-5, ∞)
Range is: [-2, ∞)

Please explain for me
Answer:
11
Step-by-step explanation:
You have to first make the 7 into a fraction (7/1) then keep, change, flip.
You keep the 7/1 as it is, you change the division sign into a multiplication sign, and you flip the 7/11 to 11/7. You then just multiply straight across to get 77/7 which is the same thing as 11/1 which is the same thing as 11!

Ben can type 2/5 of a page of an essay in 1/2 minute. How much time would
take him to type one full page of the essay?
Answer:
ok so first i want to figure out what 2/5 converted to percent is......
you can find it out on a calculator or on paper by dividing 2 / 5 = 0.4
so this is 40% and if it takes him half a minute to do this, it takes him about 30 seconds to finish 40% of the essay and there is a full 60% still waiting to be done, so lets see,
40% + 40% = 80%
so that is about 1 full minute to write 80% we are still left with 20% so let's see how much time does it take to write 20% of the essay, in 40% it takes 30 seconds and in 80% it takes 60 seconds. So since 20% is half of 40% then we must divide the time in half so 30 / 2 = 15
So if we add all these numbers up it equals 1:15 minutes to write an essay
I hope this helps and please mark brainliest if i got it right!
The time taken by Ben to write a full page will be 1:15 minutes.
