A perimeter of a rectangle is:

They give you the width, but let's convert it to an improper fraction first:

The length is twice the width so it is:

Now, we are ready to solve, plug in values in the perimeter formula:

So, 40 is your answer.
3.06 rounded to the nearest whole number is 3.
.06 is much closer to 0 than it is to 1, so round down.
3.06 rounded down is 3, so that is your answer.
Hello,
Let's a and b the 2 angles.
a+b=180 (1)
a=b/3+8 ==> 3a-b=24 (2)
(1)+(2)==>4a=204==>a=51(°) and b=180-51=129(°)
Proof:
129/3+8=43+8=51
129+51=180
Judging by the question I noticed that the two both share x^3 in common. You can divide x^4 by x^3 and get x as a result, and x^3 can still divide into itself.
Thus your answer should be C, x^3
Answer:
a. 3
Step-by-step explanation:
An independent variable is the variable that is changed in an experiment to test its effects on the dependent variable. i.e. inputs
A dependent variable is the variable being tested, measured or predicted in an experiment. I.e a outcome
In this case, the the effects of the amount tutors are paid a week before exam, the amount of sleep before exam and the number of study hours are input variables to determine or predict a students score in exam
The independent variables are;
x1 =represents the amount paid to a tutor (in dollars) in the week before the exam
x2 = represents the number of hours of sleep in the week before the exam
x3 = number of study hours in the week before the exam
The dependent variable is the exam score
B0, B1, B2,B3, B4 are coefficients
