Answer:
Step-by-step explanation:
"length is 4 meters less than 2 times the width"
L = 2W+4
"perimeter is 40 meters"
2L+2W = 40
L+W = 20
(2W+4) + W = 20
3W + 4 = 20
W = 16/3 meters
Answer:
16.35
Step-by-step explanation:
Using an inverse normal distribution, we can calculate the z score given the percentile, which can then be used to find our value.
First, we can use an inverse normal distribution calculator to figure out that the z score given the 75th percentile is 0.674.
Next, we know that the z score is (observed value - mean) / standard deviation. We can plug our values in to get

Rounding, we get x = 16.35 as our answer

Answer:
x = 18.64
Step-by-step explanation:
use tan:
⇒ tan = 
⇒ tan 46 = 
tan of 46 is 1.0355
⇒ 1.0356 = 
multiply 18 on both sides
⇒ 1.0355 x 18 =
x 18
⇒ 18.64 = x
