Area of a triangle=1/2(base x height)
Area=72, Base=8, Height=2x-3
Plug it in.
72=1/2(8 x (2x-3))
72=1/2(16x-24)
72=8x-12
84=8x
x=10.5
If the weight of the bottom box is b then the weight of a stack of four boxes is b + b/2 + b/4 + b/8
= 8b/8 + 4b/8 + 2b/8 + 1b/8
= 15/8 b
A stack must weigh less than 100 pounds
15/8 b < 100
b < 100 x 8/15 = 53 1/3 pounds
If boxes have a minimum weight of 1 pound then
for stacks that contain 4 boxes the range of b is [8, 53 1/3)
and if stacks contain 1 to 4 boxes the range of b is [1, 53 1/3)
If the only restriction is a maximum of 100 then the range of b is [0, 53 1/3)

Answer:
15 dog heights;
Step-by-step explanation:
The formula to be used here is where:
- is the confidence level
- is the margin of error for a confidence level
- is the critical value for the confidence level
- is the population standard deviation
- is the sample size
We are given that:
To determine the minimum sample size, , we plug our given values into the formula and solve for
Don't forget to round up here! This means that actually.
Therefore, if we want to be 95% confident that the sample mean is within 1 inch of the true population mean, the minimum sample size that can be taken is 15 dog heights.

Answer:
It would be 1.2x+ + 1.5
Step-by-step explanation:
Here's why. Since they are both growing at the same rate and it can't be 1.95 or the second one would be 9.75 you have a starting price for 0 miles that being 1.50 and take the remaining amount and divide
