So long as the perimeters are the same, rectangles and squares share the same area. For example, a square that is 2m by 2m across is 4m squared. A rectangle of 4m by 1m across is still 4m squared.
Therefore all we want to do here is see how big we can make our “square” perimeter using the creek. We have three sides to spread 580ft across, therefore if we divide this by 3, we get 193.3ft of fencing per side. If we then square this figure, we will then get the maximum possible area, which comes to 37,377ft squared. (That’s a huge garden).
Answer:
a) 450. b) 1:1.25 c) 32 rooms
Step-by-step explanation:
1. 100*4.5 = 450
2. 16:20 divide by 4 -> 4:5 (simplifies to 1:1.25)
3. 64/2 = 32 rooms needed. They have 16.
Sorry if answers are wrong, the picture quality is really poor for me.
Answer:
D
Step-by-step explanation:
This comes out to 4. The other ones are absolute value, meaning there are no negatives. You can think of subtracting as adding a negative. When you role a dice however, you are never really moving backward.

In order to find the concentration after 11 minutes, let's use the value of t = 11 in the function C(t) and then calculate its value:

Rounding to three decimal places, we have a concentration of 0.036.
