Raymond just got done jumping at Super Bounce Trampoline Center. The total cost of his session was \$43.25$43.25dollar sign, 43,

rodikova [14]

Answer:

Raymond was for 29 minutes on the trampoline.

Step-by-step explanation:

We are given the following in the question:

Total cost of session = $43.25

Entrance fee = $7

Cost per minute = $1.25

Let t be the minutes that Raymond was on the trampoline.

Thus, we can write

Total cost =

Entrance fee + cost per mute(minutes that Raymond was on trampoline)

$C(t) = 7 + 1.25t$

Putting the values, we get,

$43.25 = 7 + 1.25(t)\\1.25t = 43.25 - 7\\1.25t = 36.25\\\\t = \dfrac{36.25}{1.25}\\\\t = 29$

Thus, Raymond was for 29 minutes on the trampoline.

A valve in a full 6000 gallon water tank is slowly opening. Water flows out of the tank through the valve. The flow rate in gall

Wittaler [7]

The volume of the gallon is 6000 gallon
the rate of water flow per min is f(t)=300t^2
a] amount of water that flowed in the first 7 minutes=7/60 hours will be:
f(7)=300(7/60)^2
solving the above we get
f(7)=7/12 gallons

b] The time taken for the tank to be empty will be as follows:
amount of water that will flow out for the tank to be empty will be 6000 gallons
thus,
6000=300t^2
this can be simplified to
20=t^2
t^2-20=0
solving this we get:
t=-2√5 or 2√5
the time taken for the tank to be empty will be t=2√5 hours=5.4721 hours

Value of X. Please give step by step so I understand

otez555 [7]

Answer:

The value of x is 15.

Step-by-step explanation:

Since the base is 40 inches long, and the two triangles are congruent - both are right triangles and have sides x and their bases equal - you know that each base of a triangle is 20 inches long. Using the Pythagorean Theorem, you can get that $x^2+20^2=25^2$ . Solve for x by isolating the variable on one side: $x^{2} =25^{2} - 20^{2}$ ⇒ $x^{2} = 625 - 400$ ⇒ $x^{2} = 225$ ⇒ $x^{2} =225$ ⇒ $x=\sqrt{225}$ ⇒ $x=15$ inches.
