Simplify 27 to the negative 2 thirds power. 9 1 over 9 negative 1 over 9 −9

zimovet [89]

Answer:

The answer is 1/9 ⇒ the second answer

Step-by-step explanation:

* In the exponential functions we have some rules

(1) b^(-m) = 1/(b^m) (for all nonzero real numbers b)

- If we have negative power we reciprocal the base

to get positive power

(2) (b^m)^n = b^(mn)

- If we have power over power we multiply them

* In our problem: $(27)^{-\frac{2}{3}}$

- At first change 27 to b^n

∵ 27 = 3 × 3 × 3 = 3³

∴ $27^{-\frac{2}{3}}=(3^{3})^{-\frac{2}{3}}$

* Lets use rule (2)

∴ $27^{-\frac{2}{3}}=3^{-2}$ ⇒ 3 × -2/3 = -2

* Use rule (1)

∴ $3^{-2}=\frac{1}{3^{2}}=\frac{1}{9}$ ⇒ reciprocal the fraction to change the sig of the power

* The answer is 1/9

CAN ANYBODY FIGURE THIS OUT

eimsori [14]

Because you are told the two are similar, find the ratio of them.

Side AB = ft and side EF is 25 feet.

This means the larger rectangle is 5 times larger ( 25 /5 = 5).

Area is in square units, so square the ratio: 5^2 = 25

The area of the larger rectangle is 25 times the area of the smaller one.

Area = 35 x 25 = 875 ft^2

Hong reads 9 3/4 chapters in 3 3/8 hours. What is the unit rate in chapters per hour? Write your answer as a fraction or a mixed

Sav [38]

The unit rate is: $2\frac{8}{9}$ chapters per hour

Step-by-step explanation:

Given

chapters read = $9\frac{3}{4} = \frac{39}{4}$

Time = $3\frac{3}{8} = \frac{27}{8}$

Unit rate is calculated by dividing the total chapters by total time

So,

$Unit\ rate = \frac{\frac{39}{4}}{\frac{27}{8}}\\= \frac{39}{4} * \frac{8}{27}\\= 13 * \frac{2}{9}\\=\frac{26}{9}\\=2\frac{8}{9}$

Hence,

The unit rate is: $2\frac{8}{9}$ chapters per hour
