If g(x) = 2(x − 4), find the value of x if g(x) = 20. 32 12

nlexa [21]

Answer:

The value of x is $14$

Step-by-step explanation:

we have

$g(x)=2(x-4)$ ------> equation A

In this problem we have

$g(x)=20$

Substitute the value of g(x) in the equation A and solve for x

$20=2(x-4)$

Divide by $2$ both sides

$20/2=2(x-4)/2$

$10=(x-4)$

Adds $4$ both sides

$10+4=(x-4)+4$

$x=14$

A water tank has a diameter of 15 ft and is 22 ft high. a. What is the volume of the tank in ft?? b. In m?? c. In cm?

rodikova [14]

Answer:

a) $V = 3887.72 ft^{3}$

b) $V = 104.97 m^{3}$

c) $V = 104,968,468.538 cm^{3}$

Step-by-step explanation:

A tank has the format of a cylinder.

The volume of the cylinder is given by:

$V = \pi r^{2}h$

In which r is the radius and h is the heigth.

The problem states that the diameter is measured to be 15.00 ft. The radius is half the diameter. So, for this tank

$r = \frac{15}{2} = 7.50$ ft

The height of the tank is 22 ft, so $h = 22$ .

a) Volume of the tank in $ft^{3}$ :

$V = \pi r^{2}h$

$V = pi*(7.5)^2*22$

$V = 3887.72 ft^{3}$

b) Volume of the tank in $m^{3}$ :

We must convert both the radius and the height to m.

Each feet has 0.30 m, so:

Radius:

1 feet - 0.30m

7.5 feet - r m

$r = 7.5*0.30$

$r = 2.25m$

Height

1 feet - 0.30m

22f - h m

$h = 22*0.30$

$r = 6.60m$

The volume is:

$V = \pi r^{2}h$

$V = pi*(2.25)^2*6.60$

$V = 104.97 m^{3}$

c) Volume of the tank in $cm^{3}$ :

Each m has 100 cm.

So $r = 2.25m = 225cm$

$h = 6.60m = 660cm$

The volume is:

$V = \pi r^{2}h$

$V = pi*(225)^2*660$

$V = 104,968,468.538 cm^{3}$

at a concert, 2/5 of the people were men.there were 3 times as many women as children. if there were 45 more men than children h

kenny6666 [7]

People: p
men: 2/5 p 
children: c 
women: 3c 
men: 2/5 p = c+45 
people = m+w+c = 2/5 p + 3c + c 

so, p = 2/5 p + 4c 

3/5 p = 4c 
2/5 p = c+45 

c=27 
p=180 
180 people at the show. 

so, women=81 
men=72

A toy rocket is launched from a platform 42 feet above the ground at a speed of 91 feet per second. The height of the rocket in

True [87]

Lets get started!

height = -16t² + 91t + 42
After 3 sec means, t = 3, so we substitute t with 3

H = -16(3)² + 91(3) + 42
= -144 + 273 + 42
= 171 feet
