Answer:
Step-by-step explanation:
I=PRT where I =interest P=principal, R=rate, and T =time is
Rice: .5(8) = 4kg (4000 g)
Popcorn: 150(12) = 1800 g
Total mass = mass of rice (4000 g) + mass of popcorn (1800g)
So...
Total mass = 5,800 g (or 5.8 kg)
Answer:
c=71/23 or 3 2/23 or 3.08695652...
Hello!
If you want to find an equation that is parallel to another equation, and passing through the point (1, 4), you need to create a new equation with the same slope, you need to substitute the given point into the new equation to find the y-intercept.
m = 3, y = 3x + b (substitute the ordered pair)
4 = 3(1) + b (simplify)
4 = 3 + b (subtract 3 from both sides)
b = 1
Therefore, the line parallel to the line y = 3x - 2 and passing through the point (1, 4) is y = 3x + 1.
Answer:
h(t) = -16t² + 200
distance = 56 ft
Step-by-step explanation:
First of all, we know that the initial velocity (v0) of the rock is 0 ft/s because the rock was dropped. We also know that the initial height of the rock is 200 ft because it was dropped at the top of the well which is 200 ft high. Plugging this information into our quadratic function we get h(t) = -16t² + 200.
Now we need to find the distance from the surface of the water to the bottom of the well. This distance is equal to the height of the rock at time equals 3 seconds. Therefore, all we need to do is find h(3) = -16(3)² + 200 = 56 ft.
