j= 13.5
why?
times 4.5 by three and you get 13.5
if you do 13.5/3 then you would get 4.5
easy peasy ♥️♥️♥️♥️
John can do 43 things. The ratio is 3:5 and the rate is .6. .6*72 is 43.2 which I rounded to 43
The ten thousands digit is the 8 to the left edge.
You need to increase this digit because the thousands digit is greater than zero.
The answer is 90,000.
Answer:
The area is 13,3 squared meters
Step-by-step explanation:
The 400 meters of fencing is the perimeter of the area. We know that:
perimeter = 2 (length + width)
or
P = 2 (l+w)
We also know that the length is twice the width, hence:
l = 2w
Substituting this information in the perimeter equation:
P = 2 (2w + w)
P = 4w+2w
P = 6w
w = P/6
Now, the area is defined as:
A = l*w
Therefore,
A = 2*w*w
A = 2 * w^2
Putting the w =P/6 in the previous equation
A = 2 * (P/6)^2
A = 2 * P^2/36
A = P^2/12
And substituting the value of P and doing the math,
A = 13, 333 period 3 which we need to round to 13,3 which is the total number of significant digits given
