A rectangular piece of paper has side lengths of 30 cm and 25 cm.
babunello [35]

Answer:

480 cm²

Step-by-step explanation:

New side lengths:

80% of 30 cm = 0.8% × 30 cm = 24 cm

80% of 25 cm = 0.8 × 25 cm = 20 cm

area = length × width

area = 24 cm × 20 cm

area = 480 cm²

You are comparing apples to oranges in a fruit bowl. Is the ratio 2:3 the same as the ratio 3:2?
alexira [117]

Answer:

No, the two ratios are not the same.

Step-by-step explanation:

When we are saying "apples to oranges", mathematically it means:

\frac{Apples}{Oranges},

Which could be 2:3 or 3:2, which in fractional from are written as \frac{2}{3} and \frac{3}{2} respectively.

We see that

\frac{2}{3} \neq \frac{3}{20}.

In words the ratio 2:3  says "for every two apples there are three oranges", and 3:2 says "for every three apples there are two oranges". Again we see that  the two sentences are not saying the same thing, therefore the ratio 2:3 is not same as 3:2.

Did I do this right????
Svetlanka [38]

Answer:

x = -7, y = -3 yup you did it right!

Step-by-step explanation:

Solve the following system:

{-2 y + x = -1 | (equation 1)

8 y - 5 x = 11 | (equation 2)

Swap equation 1 with equation 2:

{-(5 x) + 8 y = 11 | (equation 1)

x - 2 y = -1 | (equation 2)

Add 1/5 × (equation 1) to equation 2:

{-(5 x) + 8 y = 11 | (equation 1)

0 x - (2 y)/5 = 6/5 | (equation 2)

Multiply equation 2 by 5/2:

{-(5 x) + 8 y = 11 | (equation 1)

0 x - y = 3 | (equation 2)

Multiply equation 2 by -1:

{-(5 x) + 8 y = 11 | (equation 1)

0 x + y = -3 | (equation 2)

Subtract 8 × (equation 2) from equation 1:

{-(5 x) + 0 y = 35 | (equation 1)

0 x + y = -3 | (equation 2)

Divide equation 1 by -5:

{x + 0 y = -7 | (equation 1)

0 x + y = -3 | (equation 2)

Collect results:

Answer: {x = -7, y = -3
