Answer:

√x

Step-by-step explanation:

The given expression

1/x^-3/6

Can be written as

1/x^-1/2

Use the negative exponent rule

1/x^n = x^n

Using the rule from above above

1 * x^-1/2

1 * √x =

√x

When mushrooms are dried, they lose 80 percent of their mass. What weight of mushrooms must be picked to get 1 kg of dry mushroo

kaheart [24]

Answer:

We need to start with 5 kg of mushrooms

Step-by-step explanation:

The total of the dried mushrooms = mushrooms * percentage of weight kept

percentage of weight kept = 1- 80% = 20 %

We want 1 kg of dried mushrooms. Substitute in what we know

1 kg = mushrooms * 20%

1 kg = mushrooms * .2

Divide each side by .2

1 /.2 = mushroom *.2 /.2

5 kg = mushrooms

We need to start with 5 kg of mushrooms

Factor completely 16x8 − 1.

marta [7]

<u>Given</u>:

The given expression is $16 x^{8}-1$

We need to determine the factor of the given expression.

<u>Factor</u>:

Let us rewrite the given expression.

Thus, we have;

$\left(4 x^{4}\right)^{2}-1^{2}$

Since, the above expression is of the form $a^2-b^2$ , let us apply the identity $a^2-b^2=(a+b)(a-b)$

Thus, we have;

$\left(4 x^{4}+1\right)\left(4 x^{4}-1\right)$ ------ (1)

Now, we shall factor the term $4x^4-1$

$4x^4-1=(2x^2)^2-1^2$

$=(2x^2+1)(2x^2-1)$

Substituting the above expression in equation (1), we have;

$\left(4 x^{4}+1\right)\left(2 x^{2}+1\right)(2x^2-1)$

Therefore, the factor of the given expression is $\left(4 x^{4}+1\right)\left(2 x^{2}+1\right)(2x^2-1)$

Hence, Option B is the correct answer.

Two complementary angles measure (9x+27) and (x+50) degrees. what is the value of x?

Aloiza [94]

Complementary angles mean that the sum is Equal to 90. So

(9x+27)+(x+50) = 90

10x + 77 = 90 (combine like terms)
10x = 13 (subtraction property of equality)
x=1.3 (division property of equality)
