Car 6 truck 10 suv 14 minivan 15 at this rate if 150 vehicles passed Luann how many more mini vans than cars would pass her

inessss [21]

Answer:

number of minivans more than number of car = 30

Step-by-step explanation:

we have the rate of number of vehicles passed in one unit of time

Number of cars = 6

Number of trucks = 10

Number of SUV = 14

and number of minivan = 15

Total vehicle passed in one unit of time = 6+10+14+15 = 45 vehicle per unit time.

we can see the ratio of vehicles with each other can be given as:

6x+10x+14x+15x = 150

Now we can solve for x to get the number of cars and minivans in 145 vehicles.

or 45x = 150

or x = 150÷45 = $\frac{10}{3}$

so, number of cars in 150 vehicles = 6x = 6× $\frac{10}{3}$ = 20 cars

number of minivan in 150 vehicles = 15x = 15× $\frac{10}{3}$ = 50 minivans.

So, number of minivans more than number of car = 50 - 20 = 30

Solve this equation pls

Aleksandr-060686 [28]

Answer:

${ \rm{y = \frac{3 \sqrt{x} + 2x}{ {4x}^{2} } }} \\$

• We are gonna use the quotient rule

${ \boxed{ \bf{ \frac{dy}{dx} = \frac{ {\huge{v} } \frac{du}{dx} - { \huge{u}} \frac{dv}{dx} }{ {v}^{2} } }}} \\$

u is (3√x + 2x)
v is 4x²
du/dx is 3/2√x
dv/dx is 8x

• Therefore:

${ \rm{ \frac{dy}{dx} = \frac{(4 {x}^{2})( \frac{3}{2 \sqrt{x} }) - (3 \sqrt{x} + 2x)(8x) }{16 {x}^{4} } }} \\ \\ { \rm{ \frac{dy}{dx} = \frac{(6 {x}^{2})( {x}^{ - \frac{1}{2} } ) - (24 {x}^{ \frac{3}{2} } + 16 {x}^{2} ) }{16 {x}^{4} } }} \\ \\ { \rm{ \frac{dy}{dx} = \frac{ 6 {x}^{ \frac{3}{2} } - {24x}^{ \frac{3}{2} } - {16x}^{2} }{16 {x}^{4} } }} \\ \\ { \rm{ \frac{dy}{dx} = \frac{ - 18 {x}^{ \frac{3}{2} } - 16 {x}^{2} }{16 {x}^{4} } }} \\ \\ { \rm{ \frac{dy}{dx} = - 2 {x}^{ \frac{3}{2} } (9 + 8 {x}^{ \frac{4}{3} } ) \div 16 {x}^{4} }} \\ \\ { \boxed{ \boxed{ \rm{ \: \: \frac{dy}{dx} = - \frac{8 \sqrt{ {x}^{ \frac{8}{3} }} + 9}{8x {}^{ \frac{8}{3} } } \: \: }}}}$
