Answer:
The larges perimeter she can make becomes is 96 ft
Step-by-step explanation:
Here we note that the available brick is 47 ft²
Therefore, she has 47 square cement blocks
Let the length of the sides of the rectangle with the most perimeter be x and y
Then 2·x + 2·y = 47 which is not possible because 47 is a prime number
Hence we have the possible sides of the rectangle is a single line of square blocks such that
x × y = 47 ft² where y = 1 hence x = 47
The larges perimeter she can make becomes, 2 × (1 + 47) = 96 ft.
A. X is the number of years after 2000
2006-200 = 6 years.
Replace x with 6 and solve:
105(6)^2 + 680(6) + 4296 = 12,156
Answer for part a: 12,156
Answer for part B.
There was just over 12,000 in 6 years , to get to 21,500 would be a little over 9,000 more 9/12 = 0.75
6 years x .75 = 4.5 years
6 + 4.5 = 10.5 years round to 10 years for estimating purposes
Answer for part b: about 10 years

Answer:
<h3>37.5m/s</h3>
Step-by-step explanation:
If a coal train in Montana starts from rest and accelerates at 2.5 m/s2 for 15s,let us calculate the final velocity of the train.
Use the equation of motion v = u + at where;
v is the final velocity
u is the initial velocity = 0m/s (starts from rest)
a is the acceleration = 2.5m/s²
t is the time = 15secs
Substituting the given parameters into the formula;
v = 0+(2.5)(15)
v = 0+37.5
v = 37.5m/s
Hence the final velocity of the train is 37.5m/s
