This would be false m8 because .02 would equal 1/5. .01 would equal 1/10
-2 + 5n = 4n + 2 Given
-4 + 5n = 4n Subtract 2 from both sides
-4 = -n Subtract 5n from both sides
4 = n Divide both sides by -1
Answer:
n = 4
We have that
<span>Cylinder A has a radius of 2 feet and a height of 4 feet
so
volume of the cylinder A=pi*r</span>²*h-----> pi*2²*4-----> 16*pi ft³
<span>Cylinder B also has a height of 4 feet, but the radius has been doubled
</span>h=4 ft
r=2*2---> 4 ft
so
volume of the cylinder B=pi*r²*h-----> pi*4²*4-----> 64*pi ft³
volume cylinder B/volume cylinder A=64*pi/(16*pi)----> 4
therefore
the answer is the option
<span>C) When the radius is doubled, the resulting volume is 4 times the original volume.</span>
Answer:
140 feet.
Step-by-step explanation:
Given that size of the playground is 30 foot by 40 foot.
That means length L = 30 foot
Width W = 40 foot.
Now we need to find the lenght of the fence that is needed for the playground. Fencing is done on the sides of the playground so basically we are going to find the perimeter.
which can be found using formula
perimeter = 2(L+W)
perimeter = 2(30+40)
perimeter = 2(70)
perimeter = 140
Hence total fence needed is 140 feet.
Answer:
Step-by-step explanation:
Trace a linha de 8cm, daí você vai dividir ela no meio, ou seja, no 4. Aí é só contar 2 cm para cada lado, que vai ser o 1, as pontas vão ser o 2. Tendeu? Daí é só marcar os pontos no -3/7(~-2,3), 1,6, 7/5(1,4), -1 e 0
