This would be the distributive property, so multiply 3 by each term in the parentheses:
3*(5/4n) + 3*1.8 = 3.75n + 5.4,
Answer:
Subtraction
Step-by-step explanation:
9-2=7. The rabbit weighs 7lbs
Add them to cancel y
x+5y=8
<u>2x-5y=1 +</u>
3x+0y=9
3x=9
divide boht isdes by 3
x=3
sub back
x+5y=8
3+5y=8
minus 3
5y=5
divide 5
y=1

<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

A = pi (r)^2
so with 222r
circle changes by a factor of 222^2
