Answer:
The surface area is 302 in²
Step-by-step explanation:
Known :
Long (l) = 11 in
Weight (w) = 6 in
Height (h) = 5 in
Asked :
Surface Area (Sa) = ...?
Answer :
Formula :
= 2(l.w) + 2(l.h) + 2(w.h)
= 
= 2 (11×6 + 11×5 + 6×5)
= 2 (66 + 55 + 30)
= 2 × 151
= <u>3</u><u>0</u><u>2</u><u> </u><u>in²</u>
So, the surface area is 302 in²

Answer:
The price been reduced by a percentage of 40%
Step-by-step explanation:
we know that
$39.95 -----> represent the 100%
so
The difference of prices is equal to ($39.95-$23.97)=$15.98
Using proportion
Find the percentage of the difference
100/39.95=x/15.98
x=100*15.98/39.95
x=40%
Www,mathpapa.com type in the calculator and it gives you the full answer including the graph.
First angle is x
x + (x + 45) + 2x = 180
4x + 45 = 180
4x = 180 - 45 = 135
x = 135 divided by 4
x = 33.75
first angle 33.75
second angle 78.75
third angle 67.5
checking
33.75 + 78.75 + 67.5 = 180
Answer:
u = -3
Step-by-step explanation:
12 - 2u = 9u + 45
2u - 12 = -9u - 45
2u + 9u = 12 - 45
11u = -33
u = -33/11
u = -3
