Answer:

$79.99

Step-by-step explanation:

The error is in step 3.  He needed to ADD 72.50 to both sides of the equation.  Instead, he added 72.50 to the left side and subtracted 72.50 from the right side.

<u>Correction calculation</u>

5(r - 14.50) = 327.45

5r - 72.50 = 327.45

             5r = 399.95

                r = 79.99

The regular price is $79.99

Answer:

$79.99

Correct method:

\rightarrow \sf 5(r-14.5)=327.45

\rightarrow \sf 5r-72.5=327.45

\rightarrow \sf 5r=327.45+72.5

\rightarrow \sf 5r=399.95

\rightarrow \sf r=\dfrac{399.95}{5}

\rightarrow \sf r=79.99

The regular price is $79.99

Anni [7]

So 10% of 12=1.2 divided by

2 to get 5% which is 0.6 so because it’s increasing the amount you do $12 + 0.6 =

____ [38]

Answer:

Both boxes have the same amount of work applied to them. The smaller box will get to the end first.

Step-by-step explanation:

For the 400 kg box, we can say,

force = 1 newton

force = mass*acceleration

1 = 400*acceleration

acceleration = 1/400 meters per second^2

acceleration = 0.0025 meters per second^2

Each second, the larger box's velocity is increasing by 0.0025 meters per second.

While the smaller box would have an acceleration of...

force = 1 newton

force = mass*acceleration

1 = 200*acceleration

acceleration = 1/200 meters per second^2

acceleration = 0.005 meters per second^2

Which is twice as much as the larger box.

Put simply: if the force applied is the same for the two boxes, then the smaller box will have larger acceleration. This is because more force is needed to push on the larger mass.

Because the smaller box has more acceleration, it will naturally travel faster compared to the larger box. Therefore, the smaller box reaches the goal line faster.
