Answer:

Step-by-step explanation:

Ms. F......22 kids, $2 for parking, 't' for history ticket

Ms. M.....24 kids, $3 for lunch, 1.5 times 't' for science ticket

(I'm unsure if Ms. M's kids have to pay for parking, I'll add that at the end)

So, Ms. F...... 22 kids times $2 parking plus 22 kids times t for tickets...

22(2)+22t=?????

The last sentence tells us what it equals.

Ms. M.....24 kids times $3 for lunch plus 24 kids times 1.5t for museum...

24(3)+24(1.5t)=?????

(If Ms. M's kids have to pay parking...add 24 time $2 for parking.....use this equation, If they don't pay parking use the equation above for her kids)

24(3)+24(1.5t)+24(2)=

The perimeter of the rectangle below is 132 units. Find the length of side AB.

melisa1 [442]

Answer:

AB = 35

Step-by-step explanation:

For the value of variable z....;

;Perimetre = 132

; 132 = 2(4z + 3) + 2(5z)

; 132 = 8z + 6 + 10z

; 132 - 6 = 8z + 10z

; 126 = 18z

;the value of...z = 7

Therefore the value of length AB;

AB = 5z...then substitute the value of z into the length of AB

; AB = 5(7)

;AB = 35

Alexxandr [17]

Answer:

0.77

Step-by-step explanation:

From the information given:

The breakdown time (a)= 3 hours

The breakdown rate (λ) = 1/a = 1/3

Average flow time in the system (W) = 2.305 hours

For the entire system;

The average down machines L = Wλ

= 2.305 × (1/3)

= 0.77

A particular airport has beacons on the ground 5 km out from the start of each runway. An airplane is directly over this beacon

AleksAgata [21]

Answer:

The direct distance from the plane to the start of the runway is approximately 5.0623 km

Step-by-step explanation:

The locations of the beacons on the runway, x = 5 km from the start of each runway

The angle of elevation of the airplane from the runway, θ = 9°

Let 'R' represent the direct distance from the plane to the start of the runway

The horizontal distance from the start of the runway to the beacon, 'x', the distance from the plane to the start of the runway, 'R', and the vertical height of the plane, 'h' form a right triangle with rides x, R, and h

By trigonometric ratios, we have;

$cos\angle \theta = \dfrac{The \ length \ of \ the \ adjacent\ leg \ to \ \angle \theta}{The \ length \ of \ the \ hypotenuse \ side} = \dfrac{x}{R}$

Therefore, we have;

$cos (9 ^{\circ}) = \dfrac{x}{R} = \dfrac{5}{R}$

From which we have;

$R= \dfrac{5}{cos (9 ^{\circ}) } \approx 5.0623$

The direct distance from the plane to the start of the runway, R ≈ 5.0623 km
