Answer:
The dimensions are:
by 
Step-by-step explanation:
The area of the rectangle is given as

The factored form of this quadratic trinomial gives the dimensions of the rectangle.
We factor 3 first to obtain;

We split the middle term to get;

We factor within the parenthesis to get;

We factor further to get;

The dimensions are:
by 
Then the perimeter will be

1/4 = 16/t.....1 elephant to 4 tigers = 16 elephants to t tigers
cross multiply
(1)(t) = (16)(4)
t = 64 <=== 64 tigers
Answer:
(29.99 + 18.65 + 32.59) 0.85 = 0
(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0
Step-by-step explanation:
The 15% off represents percentage discount. The relationship between percentage discount and total cost is given by the equation;
Actual cost - (Percentage discount) Actual cost = Total cost
The correct options are;
(29.99 + 18.65 + 32.59) 0.85 = 0
(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0
This would be written as:
4(n-11)
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
