Answer:
Step-by-step explanation:
Let total passengers be x
At station A passenger got down
x at 40%=x × 40/100=2x/5
Now remaining,
x-2x/5 = 3x/5
At station B passenger got down
3x/5 of 60 =3x/5 × 60/100=9x/25
= 3x/5 - 9x/25 =6x/25
x=25×540/6
=2250
To find the value of y in the given equation, substitute the given value of x to the equation.
y = 4x + 2x² -x³
Substitute 2 for all x's.
y = 4(2) + 2(2²) - 2³ = 8
Therefore, the value of y is 8.
It’s really hard to see the picture
Answer:
1. 30ft
2. 0.4 min
Step-by-step explanation:
In this question, apply sine law which states that sine Ф= opposite/hypotenuse
The general formulae; is SOHCAHTOA where ;
(SOH) sineФ=opposite/hypotenuse ; (COH) cosine Ф= adjacent/hypotenuse and (TOA) tan Ф=opposite/adjacent
In the question the height of the two floors is the " c" and the angel at the base is 60° and distance the conveyor travels is the hypotenuse
Hence;
If 75ft=1min
30ft=?........................simple math
30/75 = 0.4 minutes
Answer:
Step-by-step explanation:
Using the division property of power,
6 and 2 are the real numbers so just divide 2 by 6.
Using the negative properties of power
Make sure the coefficient in front x, is the numerator.
Since 3 is our coefficient, it will be 3.
