How to solve 3x-4(8x-6)=20
11Alexandr11 [23.1K]
3x -4(8x - 6) = 20

3x -32x + 24 = 20

-29x = -4

29x = 4

x = \frac{29}{4} = 7.25

The base of a solid in the xy-plane is the circle x2 + y2 = 16. Cross sections of the solid perpendicular to the y-axis are semi
Alexus [3.1K]

Answer:

The volume of the solid will be = 134.1 cubic units.

Step-by-step explanation:

The base of a solid has the equation of a circle x² + y² = 16 in the xy-plane. Cross-sections perpendicular to the y-axis of the solid are semicircles.

Therefore, the solid will be the shape of a hemisphere.

Now, the radius of the hemisphere will be 4 units.

{Since the base of the hemisphere is on the xy-plane and have equation

x² + y² = 4²}

Therefore, the volume of the solid will be = \frac{2}{3}\pi  r^{3} = (\frac{2}{3})\times (\frac{22}{7}) \times (4^{3}) = 134.1 cubic units. (Answer)

Write an equation and solve. Round to the nearest hundredth where necessary. 19 is what percent of 40?
snow_lady [41]
You first divide 40 by 19:

19/40=?

Then you convert that to percentage by dropping the decimal point and attaching a %

(hint: you should get 48% about :)

health club currently charges its 1900 clients monthly membership dues of $ 42. The board of directors decides to increase the m
just olya [345]

Answer:

The club should charge $211 to optimize the revenue.

Step-by-step explanation:

Hi there!

The current revenue of the health club is calculated by multiplying the number of clients by  the membership due value.

If y = revenue, then:

y = 1900 · 42

So, if the memberiship dues increase by $1, 5 clients will be lost. Then, if the dues increase by a value of x, then the number of lost clients will be 5x. If such an increase is applied, the revenue will be:

y = (1900 - 5x) (42 + x)

Apply distributive property:

y = 79800 + 1900x - 210x - 5x²

y = -5x² + 1690x + 79800

The function is a negative parabola, then, its maximum will be the vertex of the parabola that can be calculated using the following formula:

x = -b/2a

Where:

b = 1690

a = -5

Then:

x = -1690/(2 · -5)

x = 169

The club should charge 169 + 42 = $211 to optimize the revenue.
