Answer:
A = 16.5 cm²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A = h (b₁ + b₂ )
where h is the perpendicular height between bases and b₁, b₂ the bases
here h = 3, b₁ = 7 , b₂ = 4 , then
A = × 3 × (7 + 4) = 1.5 × 11 = 16.5 cm²
<span>Each penny is 0.75 inches in diameter
0.061 inches thick
If pennies has a diameter of 6 inches and a height of 11.5 inches
Cylinder: Diameter-6 in/ Height 11.5 in
V=3.14(r²)h
3.14(3²) (11.5)
3.14*9 (11.5)
Volume=324.99
Pennies
Diameter-0.75 in/ Height .061
V=3.14(r²)h
3.14(.375²)(0.061)
3.14*.140625 (.061)
4415625*.061
Volume=0.0269353125
324.99/0.0269353125= 12,065
pennies(approximately)
12,065 Pennies can fit in the cylinder

Old canvas = x times x =100 inches
New canvas = X times 18= 180 inches
Answer:
The value of the expression is - 5.
Step-by-step explanation:
(-2x +10) - (-6x + 5y + 12) + (x +8y - 16)=
-2x+10+6x-5y-12+x+8y-16=
(-2x+6x+x)+(-5y+8y)+(10-12-16)=
5x+3y-18
if x=5 and y=-4 then
5*5+3*(-4)-18=25-12-18=25-30=-5
