Answer:

Option (3)

Step-by-step explanation:

Since density on an element = $\frac{\text{Mass}}{\text{Volume}}$

Volume of the water in the aquarium = volume of the aquarium

= Length × width × height

= 10 × 5 × 5

= 250 cm³

We know density of the water = 1 gram per cm³

By putting these values in the formula,

1 = $\frac{\text{Mass}}{250}$

Mass = 250 g

Therefore, Option (3) will be the answer.

For which equation does it make the most sense to solve by completing the square?

daser333 [38]

The equation for which square method is possible is x²-8=1

Step-by-step explanation:

For checking which of the equation satisfies the complete square condition, we proceed by checking each of the available options

1). x²+20x=52

Rewriting it as x²+20x-52

This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 1) and independent constant (i.e. 52) is not a perfect square.

2). 5x² + 3x = 9

This equation can be rearranged as 5x²+3x-9=0

This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 5) and independent constant(i.e. 9) is not a perfect square.

3.) x² −8=1

This equation can be rearranged as x²=9

Hence x= ±3

This binomial expression is a perfect square and can be done by the square method.

4). 3x² −x+17=0

This binomial expression is not a perfect square since the product of the coefficient of x²(i.e. 3) and independent constant(i.e. 17) is not a perfect square.

Equivalent answers for 64 to the power of 2/3

madreJ [45]

Answer:

Step-by-step explanation:

Dealing with a fraction exponent on hand can be converted by using the fractional exponents rule where the fraction exponent is converted to something like this:

$64^\frac{2}{3} = \sqrt[3]{64^{2}}\\$

As you can see, the denominator of the fractional exponent is now the index of the radical. Here is a guide to know what goes where.

$64^\frac{x}{y} = \sqrt[y]{64^{x}}$

Both the original problem (64^2/3) and the converted formula can be put into a calculator.

Simplify (if you want to)

$\sqrt[3]{64^{2}}\\\sqrt[3]{4096}\\16$

64 to the power of 2/3 is 16.
