Answer:

The answer is First option

1/2^12 .

$\frac{1}{2^{12} }$

Step-by-step explanation:

Given:

(2^-3)^4

i.e

$(2^{-3} )^{4}$

To Find:

$(2^{-3} )^{4}=?$

Solution:

Law of Indices

$(x^{a}) ^{b} =x^{a\times b}\\and\\x^{-1}=\frac{1}{x}$

Using the above Property we get

∴ $(2^{-3} )^{4}=2^{-3\times 4} \\\\ (2^{-3} )^{4}=2^{-12} \\\\(2^{-3} )^{4}= \frac{1}{2^{12} }$

The answer is First option

1/2^12 .

$(2^{-3} )^{4}=\frac{1}{2^{12} }$

Eight times a number increased by 9 exceeds 7 times the number by 15. Find the number.

Alborosie

Turn it into math terms bit by bit. let x be "a number"

8 times a number is 8×x

increased by 9 is +9

7 times a number is 7×x

exceeds is minus

by 15 is =15

now we put it together.

$8 \times x + 9 - 7 \times x = 15$
solve
$8x + 9 - 7x = 15 \\ x + 9 = 15 \\ x = 6$

sasha drove from her house to the grocery store in 20 minutes. her return trip took 15 minutes. if the store is 7 miles from her

otez555 [7]

Sasha drove from her house to the grocery store in 20 minutes.
Her return trip took 15 minutes. IF the store is 7 miles from here house.
Find Sasha’s average speed for her round trip in miles per hour.
=> 20 minutes + 15 minutes = 35 minutes
=> 35 minutes is the time of her travel.
=> 7 miles is the distance.
We need to solve for the average speed.
Formula = Speed = distance / time
=> 7 / 35
=> 0.2
thus, her speed is 0.2 miles per minute (.2miles/min)
