Answer $173.53
Method
Times 0.07 and 2479 together
X=2
You first solve for y on the other equation 6x+3y=15 which will be: y=5-2x
Then you make it one equation: 3x-5=5-2x
Third step is add the -2x with the 3x which is will be 5x.
Fourth: your new equation will be 5x-5=5
Next u would add 5 plus which is 10
Lastly your new equation is 5x=10
I honestly hope this helps !!!!
Answer:
20/(9π) m/min ≈ 0.707 m/min
Step-by-step explanation:
The rate of change of height is the rate of change of volume divided by the surface area. Of course, the surface area is given by πr², where r = d/2 = 3 m.
dh/dt = (dV/dt)/A = (20 m³/min)/(π(3 m²))
dh/dt = 20/(9π) m/min ≈ 0.707 m/min
Answer:
Step-by-step explanation:
For this case, the first thing we must know is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Therefore, the total distance traveled in this case is:
(5.5) * (0.5) + (1.5) * p = 13.25
Rewriting:
2.75 + 1.5p = 13.25
Clearing the value of p we have:
p = (13.25-2.75) / (1.5)
p = 7
Answer:
an equation representing this situation is:
2.75 + 1.5p = 13.25
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour
