Answer:
Step-by-step explanation:
Given
Molly: 50 out of 200
Joel: x out of 280
Required
Find x
Start by representing the giving parameters as ration
Molly= 50 : 200
Joel = x : 280
From the question, the ratios are equivalent. So,
Convert to fractions
Solve for x
Answer: y= 1200 (1.025)^t
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form)
t= years
A = population after t years
Replacing with the values given:
1200= 1200 (1+ 2.5/100)^5
1200= 1200 (1+ 0.025)^5
1200= 1200 (1.025)^5
For the number of rabbits, y, at the end of t years
y= 1200 (1.025)^t

Answer: The first choice ( y=7x+36)
Explanation:
Since we know the slope is 7 and there is a point of (-5,1) we can easily find the b (y intercept).
Equation would be 1=7(-5)+b
First we time 7 by -5 which is -35
Next we add 35 to the other side of the equation which is 36=b
So 36 would be your y intercept
Answer:
3/4
Step-by-step explanation:
3 * 2/8
We can simply 2/8 by dividing the top and bottom by 2
3 * 1/4
3/4
Answer:
Perimeter 
Step-by-step explanation:
Let 
= width of the rectangle.
From the information "length of a rectangle is 5cm more than width", we can write:
Length = 
- - - -
Perimeter 
(formula for the perimeter of a rectangle)
∴ The expression of the perimeter of the rectangle in terms of is 
.
Hope this helps :)
