Answer:
n is less than or equal to: 10
Step-by-step explanation:
10n+20=120
subtract 20
10n=100
divide by 10
n=10
One number be x
x+(x+1)+(x+2)=63
x+x+1+x+2=63
3x+3=63
3x=63-3
3x=60
x=60:3
x=20
smallest number = x=20
middle <span>number = x+1= 20+1=21
</span>largest<span><span><span> number = x+2</span> =20+2= 22</span>
</span>
key words:
D=Diameter
R=Radius
D= 2r=2x1=2inches
so the diameter of the circle is 2 inches
hope this helps!
Volume = 12 * area of triangular base
area of triangle = 1/2 base * height = 3 * height
height = sqrt(5^2 - 3^2) = 4
area of triangle = 4*3 = 12
Vol of prism = 12*12 = 144 cubic units
