An albatross is a large bird that can fly 600 kilometers in 15 hours at a constant speed. Using LaTeX: dd for distance in kilometers and LaTeX: tt for number of hours, an equation that represents this situation is LaTeX: d=40td = 40 t . What are two constants of proportionality for the relationship between distance in kilometers and number of hours?

Answers
Answer: x = 18, y = 3
Step-by-step explanation:
Given system of liner equation is :-
From (1), we get
.........(3)
Substitute the value of x in equation (2), we get
Now, substitute the value of y in (3), we get
x = 18, y = 3
4(24+4y)/2-12y=36
48+8y-12y=36
4y=12
y=3
2x-4x3=24
2x=36
x=18

(x^n)^m=x^(mn)
(x^4)^2=x^(4*2)=x^8
(x^4)^2
= (x^4)*(x^4)
= (x*x*x*x)*(x*x*x*x)
= x^8
On the other hand, if you meant (x^4)2, then the answer is 2x^4

Answer:
11²= 121
5³= 125
2⁷= 128
Step-by-step explanation:
The whole numbers can be multiplied with themselves to get numbers between 120 and 130 .
For example
11*11= 121
This can be written in the exponent form as
11²= 121 which is between 120 and 130.
Also
5*5*5= 125 or
5³= 125 which is also between 120 and 130.
and
2*2*2*2*2*2*2= 128
2⁷= 128 which is between 120 and 130 as required.
We see that as the powers or exponent increases the whole number is decreased.

Answer:
Third Option.
Step-by-step explanation:
First Option:
The mode means the option that is selected the most.
There are 7 votes for 1 state, hence 1 is the mode as it is voted the most.
FALSE.
Second Option:
The median means the middle when arranged in numerical order.
Arranging them:
If you look for the middle term, it is 2 which is the median.
Therefore, the median is not 3.
FALSE.
Third Option:
Four out of 5 students lived in only 1 or 2 states.
12 students live in only 1 or 2 states.
If we count the number of people living in 1 or 2 states, we get 12.
TRUE.
Fourth Option:
There is no data for 7 states.
FALSE.
