First, subtract 4 on both sides:-

$\tt{3x=28-4}$

$\tt{3x=24}$

Divide by 3 on both sides:-

Ipatiy [6.2K]

Answer:

$8.75

Step-by-step explanation:

Given data

Bill= $25

Coupon Discount=15%

Tip= 20%

Let us first find 15% of the $25

=15/100*25

=0.15*25

=$3.75

Let us first find 20% of the $25

=20/100*25

=0.20*25

=$5

Hence the coupon and the tip combined is

=3.75+5

=$8.75

PLEASE HELP: The mass of a ball is 128 g. It has a density of 0.5 g/cm³. What is the volume of the ball? Show your work and plac

tiny-mole [99]

Answer:

Part 1) The volume of the ball is 256 cm³

Part 2) The radius of the ball is 3.94 cm

Step-by-step explanation:

Part 1) we know that

The density is equal to divide the mass by the volume

D=m/V

Solve for the volume

The volume is equal to divide the mass by the density

V=m/D

In this problem we have

m=128 g

D=0.5 g/cm³

substitute

V=128/0.5=256 cm³

Part 2) what is the radius of the ball?

we know that

The volume of the sphere (ball) is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$V=256\ cm^{3}$

assume

$\pi =3.14$

substitute and solve for r

$256=\frac{4}{3}(3.14)r^{3}$

$768=(12.56)r^{3}$

$r^{3}=768/(12.56)$

$r=3.94\ cm$
