Answer:
Yes this is a proportional relationship.
Equation is;
D=20T
Step-by-step explanation:
A horse run;
800m in 40 seconds
1200m in 60 seconds
and
480m inn 24 seconds
800m ÷ 40s = 1200m ÷ 60s = 480m ÷ 24s = 20
The equation here is Distance(D) = 20 × Time(T)
D=20T
It implies that the distance of the horse is directly proportional to the time it takes to run.
To find the area of a parallelogram, you use the area formula:
Area = Base * Height
Then, all you have to do is substitute in your known integers and solve. Therefore:
Area = 15 * 21 2/3
When we multiply these two numbers, we get
Area = 325 square yards or yards
The answer is 5.5
In a rectangle, lengths of diagonals are equal. If you draw the rectangle, you can see that KM and LN are diagonals, so they must be equal:
KM = LN
KM = 6x + 16
LN = 49
6x + 16 = 49
6x = 49 - 16
6x = 33
x = 33/6
x = 5.5
I just took the quiz, the answer is A: Critical values=0.312; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights.
