Answer:

15$

Step-by-step explanation:

Okey so first we establish that 25 is 100%

Matthew gets 60%

First we find 10% by dividing both sides by 10

2.5 = 10%

Then we times these numbers by 6 to find 60%

<u>60%  = 15</u>

Matthew will earn <u>15$</u>

Luke will earn 10$

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x
GarryVolchara [31]

Answer:

85.1 ft

Step-by-step explanation:

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

We solve using the Trigonometric function of Cosine

cos y = adjacent/hypotenuse

y = angle = 20°

Adjacent = 80 ft

Hypotenuse = ?

cos 20 = 80/Hypotenuse

Hypotenuse = 80/cos 20

x = 85.134221798 ft

Approximately = 85.1 ft

Length of the slide = 85.1 ft

Area of the triangle defined by the coordinates (-3, -4), (-7, 0), and (-3, 4).
qwelly [4]
Here: (Aₓ, Ay) = (-3,-4), (Bₓ, By) = (-7,0), (Cₓ, Cy) = (-3, 4)
Now, Formula of area of triangle is:

area = [Aₓ(By - Cy) + Bₓ(Cy - Ay) + Cₓ(Ay - By)] / 2

Substitute the values in to the expression, 
area = [-3(0-4) - 7(-4-(-4)) - 3(-4-0)] / 2
area = [-3(-4) -7(0) -3(-4)] / 2
area = [12-0+12] / 2
area = 24 / 2
area = 12

Final answer would be 12 units.

Hope this helps!

The function rule T(m)=450-8m represents the amount of water T(m) (in liters) in a holding tank after being drained at a rate of
suter [353]
Well they give you the equation and they want you to solve for time given that you know the amount of water in the tank.  They tell you T=274 and that

T=450-8m  so using the value T=274 in the equation to the left gives you:

274=450-8m  subtract 450 from both sides

-176=-8m  divide both sides by -8

22=m

So 22 minutes have passed when there is 274L remaining...
