So 4 hours for 40 dresses.
1 hour would be 40/4=10 dresses
50 dress = 1hr x 5 = 5 hrs#
Answer:
89
Step-by-step explanation:
we evaluate when t=2
so it's 89 feet
Part (a)
The length is supposed to be 22.2 cm, but it could be 0.3 cm less
So 22.2 - 0.3 = 21.9 cm is the smallest value for the length. This is the lower bound of the length.
The upper bound is 22.2 + 0.3 = 22.5 cm as it is the largest the length can get.
-------------
Use this for the width as well
The width is supposed to be 12 cm, but it could be as small as 12-0.3 = 11.7 cm and as large as 12+0.3 = 12.3 cm
-------------
<h3>Answers:</h3>
- smallest length = 21.9 cm
- largest length = 22.5 cm
- smallest width = 11.7 cm
- largest width = 12.3 cm
============================================
Part (b)
Use the smallest length and width to get the smallest possible area
smallest area = (smallest width)*(smallest length) = 11.7*21.9 = 256.23
-------------
Repeat the same idea but for the largest length and width to get the largest possible area
largest area = (largest width)*(largest length) = 12.3*22.5 = 276.75
-------------
<h3>
Answers:</h3>
- smallest area = 256.23 square cm
- largest area = 276.75 square cm
Answer: (-1, -2) or (-2, 1)
Step-by-step explanation:
i graphed it on desmos and used the intersected points.
(-25) + 10 + (-5) = -20 feet is his current position. To reach zero, he should add 20 feet to his altitude.
