The right answer is the top right. 28 students chose the zoo. The 28 + 23 is the sum of the total people surveyed. Multiply it by 100 to get a percentage.
Answer:
$18,112.45 (nearest cent)
Step-by-step explanation:
Let y = value of the boat
Let x = the number of years
If the boat depreciates in value by 15% each year, then each year that goes by, it is worth 85% of the previous year's value (since 100 - 15 = 85)
85% = 85/100 = 0.85
Therefore, the equation is:
So, when x = 10:
Answer:
$12
Step-by-step explanation:
first we multiply the candies by the weight to find out the total weight
60* 25= 1500g
1500g to kg = 1500/1000 = 1.5kg
so its going to be 1.5kg * 8
1.5* 8 = 12
Answer:
Step-by-step explanation:
I find it easiest to write the equations in standard form, as above. You just need to pick numbers for the x- and y-coefficients, then see what the left-side evaluates to. I wanted the x-coefficients to be different, and one of the y-coefficients to be negative. (The x-coefficients need to be positive when the equation is written in <em>standard form</em>.)

Answer:
k=3
Step-by-step explanation:
The given polynomial is
This polynomial is divided by x+1 and the remainder is 2.
We want to find the value of k.
We can find k, using the remainder theorem.
According to the remainder theorem, when p(x) is divided by x+a, the remainder is given by p(-a).
So
This implies that:
We simplify to get:
The value of k is 3.
