Mario tried to solve an equation step by step.
Zarrin [17]

Answer:

Step 2

Step-by-step explanation:

Mario made a mistake in Step 2 when substracting \frac{1}{3} from \frac{4}{3}. When substracting his result ended up being \frac{2}{3} but it is actually....

\frac{4}{3} - \frac{1}{3} = \frac{4-1}{3} = \frac{3}{3} = 1

so the right answer is q = 1

Please help and thank you :)
Lapatulllka [165]

Answer:

500 mL

Step-by-step explanation:

1 L = 1,000 mL

   -> We use the formula of L * 1,000 = mL

1,000 mL / 2 = 500 mL

   -> We only have half of the L, so we can divide it by 2 to get the correct number of mL

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Doss [256]

Answer:

62.0496 yards separate the first platform from the second platform

Step-by-step explanation:

We have to make the conversion of both units to yards.

Each feet has 12 inches.

Each inch is 0.0278 yards.

The first platform of the Eiffel Tower is 2,280 inches above the ground.

So

2280*0.0278 = 63.384 yards above the ground.

The second platform is 376 feet above the ground.

So

376*12*0.0278 = 125.4336 yards above the ground

How many yards separate the first platform from the second platform?​

125.4336 - 63.384 = 62.0496

62.0496 yards separate the first platform from the second platform
