Answer:
528in
Step-by-step explanation:
SA formula: 2Lw + 2Lh + 2hw
for this box: 2(4×10)+2(10×16)+2(4×16)
2(40)+2(160)+2(64)
80+320+128
80+448
<u>528in</u>
As the width gets larger so does the total area
Step-by-step answer:
The first step in solving a problem of geometry and trigonometry is to draw a diagram, with all the given information in it. The attached image does just that.
Here, we have (horizontal) distance of building to the tower is 400'.
We see two right triangles, each with a leg of 400' (horizontal).
The vertical distances are denoted h1 and h2 for the angles of elevation 24 and 20 degrees respectively.
Using the definition of tangent, we have
h1= 400tan24=178.1
h2=400tan20=145.6
The height of the tower is therefore h1+h2=178.1+145.6=323.7 feet
Answer:
The statement is true
Step-by-step explanation:
The question is as following :
is divisible by 7 and 19, true or false?
The given expression is
Take 
as a common
So, 
divided 7 = 
And divided 19 = 
is divisible by 7 and 19 (<u>True</u>)
