3-(s+4)
less than- subtract
sum- addition

since it said 3 less than the sum of a number and 4 that means you would have to add s and 4

On one of the day you went to the gym, the ratio of men to women was 3 : 2.

balu736 [363]

Answer

Find out the how many women were there .

To prove

Let us assume that the x is the scalar multiple of men and women.

As given

The ratio of men to women was 3 : 2.

Than

The total number of men = 3x

The total number of women = 2x

As given

If 120 men used the gym.

thus

120 = 3x

$x = \frac{120}{3}$

x = 40

The total number of women = 2 × 40

= 80

Therefore 80 women were there in the gym .

Write the equation for the vertical line that passes through the point (5,-2)

amid [387]

If it's just a vertical line, then it could be displayed as: x = 5.

A vertical line is not actually a function, and because of such, the entire line is just the value of the x value, as it will never have enough x value.

A pharmaticeutical company is making a new medicine capsule shaped like a cylinder with a half sphere at each end. The

DerKrebs [107]

Answer:

339.12 cubic millimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The volume of the figure is equal to the volume of the two hemispheres (one sphere) plus the volume of the cylinder

step 1

Find the volume of the cylinder

The volume is given by

$V=Bh$

where

B is the area of the base of cylinder

h is the height of cylinder

we have

$B=\pi r^{2}$

we have

$h=8\ mm$

$r=6/2=3\ mm$ ----> the radius is half the diameter

$B=(3.14)(3)^{2}$

$B=28.26\ mm^2$

substitute

$V=(28.26)(8)=226.08\ mm^3$

step 2

Find the volume of the sphere

The volume is given by

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

we have

$r=6/2=3\ mm$ ----> the radius is half the diameter

substitute

$V=\frac{4}{3}(3.14)(3)^{3}=113.04\ mm^3$

step 3

Adds the volumes

$226.08+113.04=339.12\ mm^3$
