a plane has 32 seats in class A and 50 seats in class B whose sale represents a total of € 14,600. However, only 10 seats have b
slavikrds [6]
The two equations would be

32a+50b=14600
10a+40b=7000
To solve, we need to eliminate one variable.... let’s eliminate b

4(32a+50b=14600) —> 128a+200b=58400
-5(10a+40b=7000) —> -50a-200b=-35000
So when we add them together’ we get 78a = 23400
So solve that and a= 300, so class a tickets cost 300 euros each

Substitute a=300 into first equation in the system of equations at the beginning and 32(300)+50b=14600 —> 9600+50b=14600 —> 50b = 5000 or b= 100, so the cost for class b tickets is 100 euros each

Consider the equation 7*e^0.1t=47 solve the equation for t. epress the solution as a logarithm in base-e
alekssr [168]

An equation is formed of two equal expressions. The equation 7*e^0.1t=47 can be expressed as t=[ln (47/7)]/0.1.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation 7*e^0.1t=47 in terms of logarithm in terms of base-e can be solved as,

7e^{0.1t}=47\\\\e^{0.1t}=\dfrac{47}{7}\\\\0.1 t = {\rm ln}(\dfrac{47}{7})\\\\t = \dfrac{ {\rm ln}(\frac{47}{7})}{0.1}

Hence, the equation 7*e^0.1t=47 can be expressed as t=[ln (47/7)]/0.1.

PLS ESTIMATE/ 67% of 8.7
Studentka2010 [4]
67 percent of 8.7

\frac{67}{100}  \times  \frac{x}{8.7}
100x = 67 \times 8.7

100x = 582.9

Divide by 100 on both sides to isolate the x

x = 5.829
Round up (to the nearest tenth place and whole number)

x = 6
x = 5.8

Robert plays cricket. He hit the ball in such a way that it goes up 180 feet
PilotLPTM [1.2K]

Answer:

4 feet per second

Step-by-step explanation:

Hi there!

v=D/t where v is velocity (speed), D is distance and t is time

Plug in the known values (D=180 feet, t=45 seconds)

v=180/45\\v=4

Therefore, the speed of the ball is 4 feet per second.

I hope this helps!
