Hey there!
Let's first define what area means. Area is for two-dimensional shapes, and expressions how big something is and to what extent. There are formulas that can measure area because these shapes are totally flat, and there's nothing more to measure.
However, when we have three-dimensional figures such as rectangular prisms, we use surface area. Surface area measures the total area that the object takes up, and is a sum of the areas of all the faces. The formula for surface area of a rectangular prism is:
2(lw + wh + lh)
So if we had:
L = 5
W = 6
H = 3
We would have:
A = 2(5×6 + 6 × 3 + 5×3) =
2(30 + 18 + 15) =
2(48 + 15) =
2(63) =
A = 126 units cubed
Notice how it's units cubed because there's 3 dimensions.
Hope this helps!
The correct answer is B. 592
Explain
The common pattern Number is
48 - 11 = 37 + 22 = 59 - 33 = 26 + 22 = 48 - 11 = 37
37 + 22 = 59
Add 22
59 - 33 = 26
subtract 33
Answer:
$1013.42
Step-by-step explanation:
This one would be similar to the previous.
Initial investment, P = 800
Annual Interest rate, r = 12%
Number of compouding in a year, n = 4
Time Period, t = 2 years
Using formula:
Future value,
A = P(1+r/n)^(nt)
= 800 (1+0.12/4)^(4*2)
= 800 (1.03)^(8)
= 1013.42 (to the nearest cent)
Hopefully this is right! x
4a+3b=21 is open
Answer:
the answer is 77
Step-by-step explanation:
A measures 32 and B measures 109 so you subtract 109 and 32 and your answer will be 77
