The <em>total surface</em> area of the three figures are 702 square feet.
<h3>How to estimate the amount of metal needed to produce a given amount of figures</h3>
According to this problem, we are required to determine the amount of metal needed to build three pieces with the dimensions presented in the figure.
In this case, we need to estimate the <em>total</em> surface area (), in square feet, required for the production of the three pieces, that is, the product of the number of pieces (<em>n</em>), no unit, and the surface area of each piece (<em>A</em>).
Now we proceed to calculate the total surface area:
The <em>total surface</em> area of the three figures are 702 square feet.

Answer:
(√6 - √2)/4
Step-by-step explanation:
cos30°cos45° - sin30°sin45°
= cos (30 + 45)°
= cos 75°
= (√6 - √2)/4
-10 − 8s − 1 = -7 − 4s
-10-1-8s= -7-4s
-11-8s= -7-4s
move -4s to the other side
sign changes from -4s to +4s
-11-8s+4s=-7-4s+4s ( combine like terms)
-11-4s=- 7
move -11 to the other side
-11+11-4s= -7+11
-4s= 4
divide both sides by -4
to get +s
to get s by itself
-4s/-4= 4/-4
answer:
s= -1
Answer:
80, 40, 40
Step-by-step explanation:
The rule is if the number before the tens place is 5 or more round up and if it is 4 or less round down.
I like to look at it without the rule and what makes sense.
82.14: my choices are 80 or 90. What number is 82.14 closer to on the number line? 80.
38.5 The choices are 30 and 40. This number on a number line would be closer to 40
41.3 The choices are 40 and 50. On a number line this number would be closer to 40.
