Set up equations like this (keep in mind that perimeter of a rectangle is all sides added up, so two lengths and two widths):
2l + 2w = 340
l = w + 10
Plug (w + 10) in for l in the first equation and solve for w:
2(w + 10) + 2w = 340
2w + 20 + 2w = 340
4w + 20 = 340
4w = 320
w = 80
The width of the field is 80 yd. Plug 80 in for w in either equation:
l = 80 + 10
l = 90
The length of the field is 90 yd.
Others are same thing all you need to do is add them up
Answer:
The probability that all are shipped on time is 0.729
Step-by-step explanation:
Consider the provided information,
It is given that the probability that a customer's order is not shipped on time is 0.10.
So the probability that a customer's order is shipped on time is:
It is given that we need to consider independent events.
So the probability that all are shipped on time is:
Hence, the probability that all are shipped on time is 0.729
Perimeter is 54 cm. length is 15 cm so 2 x 15 =30 . so we are left with 54-30 =24 cm.so 2 x width =24 cm . so the width is 12 cm
