Answer:

x = 1, y = 1/4

Step-by-step explanation:

11x + 4 y = 12   \ \ \ ---( 1)\\9x -4y = 8 \ \ \  - - - (2)\\\\(1) + ( 2 ) => 20x + 0 = 20\\\\

            => x = 1

Substitute x = 1 in ( 1 ) :  

                            11 + 4y = 12\\4y = 12 - 11\\\\y =\frac{1}{4}

Xin leans a 26-foot ladder against a wall so that it forms an angle of 78^{\circ} ∘ with the ground. What’s the horizontal dista
defon

The ladder and the wall it leans on are illustrations of right triangle

The horizontal distance from the base of the ladder is 5.41 feet

<h3>How to determine the horizontal distance?</h3>

The given parameters are:

Length (L) = 26 feet

Angle of elevation (θ) = 78 degrees

The horizontal distance (D) is calculated using the following cosine ratio

cos(θ) = D/L

Substitute known values

cos(78) = D/26

Make D the subject

D = 26 * cos(78)

Multiply

D = 5.41

Hence, the horizontal distance from the base of the ladder is 5.41 feet

NEED HELP ASAP!!!!!!!!!!!
Arte-miy333 [17]

Answer:

Step-by-step explanation:

Let the no of cars be x and no of buses be y.

x + y = 60 -> y = 60 - x

6x + 30y = 600

with the available equations let us calculate the values of x and y.

6x + 30 * (60-x) = 600

6x + 1800 - 30x = 600

24x = 1200

x cars = 50

y buses = 10

maximum profit = 50 * 2.5 + 10 * 7.5 = $200
