kondaur [170]

Answer:

$\large\boxed{r^{-7}=\dfrac{1}{r^7}}$

Step-by-step explanation:

$\dfrac{p^{-4}q^3r^{-7}}{p^{-2}q^3p^{-2}}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=p^{-4-(-2)-(-2)}q^{3-3}r^{-7}\\\\=p^{-4+2+2}q^0r^{-7}\\\\=p^0q^0r^{-7}\\\\=r^{-7}\qquad\text{use}\ a^{-n}=\dfrac{1}{a^n}\\\\=\dfrac{1}{r^7}$

A light-year is the distance that light travels in one year. Find the number of miles in a light-year if light travels 1.86 ti

Veseljchak [2.6K]

Number of miles traveled by light in a light-year is 5.952 × 10^12 miles

Step-by-step explanation:

Step 1: Find the number of miles (distance) in a light year by using the formula for speed = Distance/Time

⇒ Distance = Speed × Time

= 1.86 × 10^5 × 1 yr (convert to seconds)

= 1.86 × 10^5 × 365 days × 24 hrs × 60 mins × 60 sec

= 1.86 × 10^5 × 31,536 × 10³

= 1.86 × 3.2 × 10^5 × 10^7

= 5.952 × 10^12 miles

Lina's green pepper plant was 32.65 cm tall in June. During the months of July, August, and September the plant grew 2.6 cm ever

butalik [34]

Answer:

40.45 cm

Step-by-step explanation:

Length of Lina's green pepper plant = 32.65 cm

It grows 2.6 cm during the months of July, August, and September.

Length at the end of July = 32.65 cm + 2.6 cm = 35.25 cm

Length at the end of August = 35.25 cm + 2.6 cm = 37.85 cm

Length at the end of September = 37.85 cm + 2.6 cm = 40.45 cm

So, its length will become 40.45 cm at the end of September.

Y'all- this question make's 0 sense to my big brain help me out

gregori [183]

Answer:

D. for the first one, A. for the second (not certain)

Step-by-step explanation:

1. 36/2 (two books every visit) = 18, multiplied by 3 because that's how many often he does to the library (every 3 weeks)

2. 13/2 = w/5 because for every 13 cups of water, there is two cups of cleaner, so for w (unknown amount of water) there would be 5 cups of concontrated cleaner.

PLEASE HELP!

-----------------------------------------------
Information Given:
-----------------------------------------------
ON = 7x - 9
LM = 6x + 4
MN = x - 7
OL = 2y - 7

-----------------------------------------------
Since it is a parallelogram:
-----------------------------------------------
ON = LM and
MN = OL

-----------------------------------------------
ON = LM:
-----------------------------------------------
7x - 9 = 6x + 4

-----------------------------------------------
Subtract 6x from both sides:
-----------------------------------------------
x - 9 = 4

-----------------------------------------------
Add 9 to both sides:
-----------------------------------------------
x = 13

-----------------------------------------------
MN = OL:
-----------------------------------------------
x - 7 = 2y - 7

-----------------------------------------------
Sub x = 13:
-----------------------------------------------
13 - 7 = 2y - 7

-----------------------------------------------
Simplify:
-----------------------------------------------
6 = 2y - 7

-----------------------------------------------
Add 7 on both sides:
-----------------------------------------------
13 = 2y

-----------------------------------------------
Divide by 2:
-----------------------------------------------
y = 13/2

-----------------------------------------------
Answer: x = 13, y = 13/2 (Answer D)
