Answer D. Felicia spends 50% of her monthly budget on car payment and cellphone

Step-by-step explanation: If you add 125+275 it equals to 400, and 400 divided by 800 is equal to .50 which means 50%.

Let's write f(x)=4x-1, g(x)=-3x+5

We see f(.8)=2.2, g(.8)=2.6 close, with g a bit bigger

then f(.9)=2.6, g(.9)=2.3 also close, with f a bit bigger

We see f and g crossed somewhere between .8 and .9 at a value beween 2.2 and 2.6, so I'd guess a meet near (0.85, 2.4). Closest answer is

Answer: D (.9, 2.4)

27 solid iron spheres, each of radius 'xcm'ate melted to form a sphere with radius 'ycm',find the ratio x:y

r-ruslan [8.4K]

Answer:3:1

Step-by-step explanation:

Given

There are 27 solid spheres of radius x cm

The volume of a sphere is $\frac{4}{3}\pi r^3$

The volume of 27 old spheres is the same as the volume of a new sphere

The volume of the old spheres is

$V_o=\dfrac{4}{3}\pi x^3$

The volume of a new sphere is

$V_n=\dfrac{4}{3}\pi y^3$

Now, $V_o=V_n$

$\Rightarrow 27\times \dfrac{4}{3}\pi x^3=\dfrac{4}{3}\pi y^3\\\\\Rightarrow (\dfrac{x}{y})^3=27\\\\\Rightarrow \dfrac{x}{y}=3$
