If 1kg=2,2 lb
then
3,18 lb =3,18/2,2= 1,44 kg
Answer:
Ela segue esse modelo
f(x) = ax + b
Então, é só substituir os valores de x e de y na Lei de Formação
Ex: quando x=0, y=-1
y= ax+b
-1=a.0+b
b= -1
È onde a reta toca o eixo y, porque x=0
Agora, vamos usar outro par ordenado.
Quando x=2, y=3
3=a.2+(-1)
3=2a-1
3+1=2a
4=2a
a=4/2
a=2
A lei de formação é essa
a= 2; b=-1
f(x)= ax+b
f(x)=2x-1
The steps to determine whether the pillars have the same volume are;
First, we must know that the volume of an object of uniform surface area is the product of its Area and height.
The uniform area of each pillar is then evaluated and if equal;
Both pillars can be concluded to have the same volume.
We must first recall that for various shapes, the volume of the shape is a function of its height.
For example: a A cylinderical pillar and a rectangular prism pillar;
Volume of a cylinder = πr²h
Volume of a Cuboid = l × w × h
Since h = h.
Therefore, for both pillars to have the same volume; their Areas must be equal.
πr² = l × w

Answer:
C
Step-by-step explanation:
By tracing the figure, we see that we go around a semicricle twice and go in a straight path twice. So the perimeter of this figure consists of two semicircles and two line segments, hence the answer is C.
<span>If we are to compare which among the given fractions is smaller, we first determine the decimal equivalent of each. If we are to solve for those, we determine that 3/4 is equal to 0.75 and 1/4 is equal to 0.25. This is done by dividing the numerator by the denominator. Comparing 0.75 and 0.25, we can conclude that 0.75 or 3/4 is greater compared to 0.25 or 1/4. </span>
