Answer: 15 minutes
Step-by-step explanation:
Given : Tonya runs 8 kilometres in 60 minutes.
We know that the rate of distance covered with respect to time is given by :-
Rate of distance covered with respect to time for Tony=kilometers per minute
Let t be the time taken by her to run 2 kilometers.
Then, Rate of distance covered with respect to time =
If rate remains the same, then we have
Hence, it would take 15 minutes to run 2 kilometers.
Perimeter =a+b+c
13.9 + 10.4 + 8.5 =
32.8 in (perimeter)
32.8 is the perimeter of that triangle
r = 10 × 75
r = 10/75
p = 10/75
p = 10 × 75
For this case, we want to know what percentage of 75 represents the amount of "10". For this, we make a rule of three:
75 ---------------> 100%
10 ---------------> x
Where the variable "x" establishes the percentage that represents 10 having a base of 75.
Thus, 10 represents, approximately 13.3% of 75.
Answer:
The most appropriate option is option B. For the percentage, multiply by 100.
⇒ 13.33 percent of 75 is 10
Here we have to find the percentage
of 75 percent to get 10
Let us assume the percent is = x
Therefore,
To find the x percent of 75
Divide x by 100 and multiply it with 75
Then,
⇒ 75x/100
Now equate it to 10
Therefore,
⇒ 75x/100 = 10
⇒ 75x = 1000
⇒ x = 1000/75
⇒ x = 13.33%
Hence the percentage is,
⇒ x = 13.33%

Answer:
Domain = all real numbers
Step-by-step explanation:
The domain of a function is the set of x-values for which the function is defined.
When we have a graphical representation of a function, we look if the function is continuous for all values of x or not. If it is, the domain is the set of all real numbers. If it is not, we look from what value till what value the function is defined for , x-values basically.
Looking at this function, we see that it stretches forever to the left and forever to the upward direction (also advancing right limitless as well).
We want the domain (x values), which concerns with LEFT and RIGHT. So, we can see that this function is continuous for all values of x (it goes on and on to right and left). So we can say the domain is the set of all real numbers.
Domain = all real numbers
