Answer:True, becuase every time energy is converted to another form, is some of it is bled off and it made unusable.
Step-by-step explanation:
To find the surface area of the figure , we need to add the surface area of all the faces
So the surface area of figure = Area of two lateral rectangular faces + Area of two triangular faces + area of base
hence
Surface Area of figure = 2(10*15) + 2( 1/2 * 8 * 12) + (12*15)
= 300 + 96 + 180
= 576 square feet
So correct option is the last one
"the product of" ⇒ ___ * ___
86 ⇒ 86 . . . . . fills first blank
and
the depth of the river ⇒ d . . . . . fills second blank.
Your expression is
86 * d
Answer:
Total cost, c = 7p
Step-by-step explanation:
1pound =$7
Joe buys p pounds,
p pounds = $7 * p
p pounds = 7p
The cube has 6 this same faces.
Therefore the surface area is equal 6 · 7cm² = 42cm²
