Answer:
On the left side, she used commutative property
On the right side, she used distributive property
Step-by-step explanation:
The area of the wetland that will be covered in purple loosestrife 7 years from now is modeled by this expression.
500(1.2)^7
After evaluating the expression, the model predicts that approximately 1,792 acres of the wetland will be covered in purple loosestrife 7 years from now. This is not a valid prediction because the total area of the wetland is only 1,240 acres. So a constraint on the model is that the value of the expression 500(1.2)^t must be less than or equal to 1,240.
Answer:
Her monthly income=$1,082
Step-by-step explanation:
Step 1: Express the total monthly pay:
The total monthly pay can be expressed as follows;
A=F+(R×T)
where;
A=the total monthly income
F=fixed income per month
R=commission rate
T=total monthly sales
In our case;
F=$650 a week
R=6%=6/100=0.06
T=$7200
replacing;
A=650+(6% of 7,200)
A=650+(0.06×7,200)
A=650+432=1,082
A=$1,082
Her monthly income=$1,082
Answer: $4.34
Step-by-step explanation:
Mon: 0.6x100= 60 cents
Tue: 0.6x130= 78 cents
Wed: 0.6x145= 87 cents
Thurs: 0.6x138= 82.8 cents
Fri: 0.6x210= 126 cents
60+78+87+82.8+126= 433.8 cents
There are 100 cents in a dollar
4.33.8 cents, so 4.34 if you round up (if the last number is five or greater round up)
It would be D because you have to do the cube root on both sides. What I do is ignore the decimal and add it in later once the math is complete like on this question you can tell by process of elimination that 8 squared is 64 but you’re look for the cube root so that eliminates a and c and now just make sure the decimal is in the right place
