8 goes into 13 1 time. 13-8=5. Bring down the 2. 8 goes into 52 6 times. 52-48=4. Answer is 16 remainder 4.
Check: 16x8=128, +4 remainder equals 132.
Answer:
Volume is 80 cc
Ratio is 23 skittles per 20 cubic centimeter
Volume of a skittle is .416 cubic centimeters per skittle
Step-by-step explanation:
Volume = l*w*h = 4*4*5 = 80 cubic centimeters
192 skittles / 80 cubic centimeters is the ratio. You have to simplify it though.
192/80=46/40 23 skittles per 20 cubic centimeters
The volume of a skittle is 80 cubic centimeters/192 skittles = .416 cm^3/skittle
Answer:
x=-3
Step-by-step explanation:
If x=-3, then
x³+x²-2x+12=-27+9+6+12=-27+27=0
If this is true, then x+3 is a factor. So:
x³+x²-2x+12/x+3=x²-2x+4
So the factors of x³+x²-2x+12 are:
(x+3)(x²-2x+4)
((x²-2x+4) has no real roots)........
15% of 40 is 6
Hope this helps :D
Answer:
1.a=5cm
Surface area :6a²=6×5²=150cm²
2.r=3cm
h=5cm
total surface area of cylinder =2πr(r+h)
=2π×3(3+5)=48π cm²
3.
l=4m
b=5m
h=2m
now.surface area =2(lb+lh+bh)
=2(4*5+4*2+5*2)
=76m²
4.
r=6cm
surface area =4πr²=4*π*6²=144πcm²
5.
slant height (S)=8cm
length =breadth=(L)=4cm
Surface area of pyramid =area of base + 2* area of trainglular face
=L²+2*S*L
=4²+2*8*4
=80cm²
