a box 12 cm long, 5 cm wide and 12 cm height. A cardboard rectangle is inserted along the diagonal to divide the box vertically
Ipatiy [6.2K]

Answer:

The Cardboard dimensions are 13cm in length and 12cm in breadth

Step-by-step explanation:

We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)

Alice is saving money at a constant rate. Suppose she initially has $70 saved, and after 2 months, she has $170 saved.
timofeeve [1]

Answer:

50 dollars per month

Step-by-step explanation:

Given

Months = 2

Total = 170

Initial = 70

Required

Determine the rate of savings

Suppose in a month, she saves x amount.

In 2 months, she would save 2x

When 2x is added to the initial savings, it gives the total amount saved.

So, we have:

2x + 70 = 170

Collect Like Terms

2x = 170 - 70

2x = 100

Divide both sides by 2

x = \frac{100}{2}

x = 50

<em>Hence, she saves $50 dollars monthly</em>
