Consider the example below. Explain in your own words why the equation is wrong. (4^-2)^2=1/16

1 answer:

The above equation is false because it equals to 1/256. If the exponent outside of the parenthesis was removed, the equation would be correct.

Answer:

(1) 820

(2) 1920

Step-by-step explanation:

(1) solving 20 x 41, using associative property.

20 * 41 = (2 x 10) x 41 = 2 x (10 x 41)

= 20 x 41 = 2 x 410

= 820 = 820

(2) distribute 32 as 30 + 2 and solve.

60 x 32

= 60 x (30 + 2) = 60(30) + 60(2)

= 1800 + 120

= 1920

Answer:

0.3 galloons of water.

Step-by-step explanation:

We know that 1/5 galloons of water fills 2/3 of the bin.

So, we can write the following fraction:

$\frac{\frac{1}{5}\text{ galloons}}{\frac{2}{3}\text{ bin}}$

We want to find how many galloons will fill the entire bin or 1 whole bin. So, we can write the following proportion:

$\frac{\frac{1}{5}\text{ galloons}}{\frac{2}{3}\text{ bin}}=\frac{x\text{ galloons}}{1\text{ bin}}$

To find our answer, we need to solve for x.

So, let's cross-multiply. This yields:

$\frac{2}{3}x=\frac{1}{5}$

Multiply both sides by 3:

$3(\frac{2}{3}x)=3(\frac{1}{5})$

The left side simplifies. Multiply on the right:

$2x=\frac{3}{5}$

Now, multiply both sides by 1/2:

$\frac{1}{2}(2x)=\frac{1}{2}(\frac{3}{5})$

Simplify the left. Multiply on the right:

$x=\frac{3}{10}$

So, 3/10 of 0.3 of a gallon of water will fill the entire bin.

And we're done!

Answer:

Pythagorean Theorum is defined in Mathematics by a^2 + b^2 = c^2.

One leg (a) is 5. The other leg (b) is 13.

Let's use Pythagorean Theorum.

5^2 + 13^2 = c^2

5 • 5 = 25

13 • 13 = 169

25 + 169 = 194.
