Answer:
1Step-by-step explanation:
Given the expression [tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1}[/tex]
According to indices:
[tex]a^{-1} = \frac{1}{a}[/tex]
Applying this to the question:
[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{1}\left\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right}[/tex]
Hence:
[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]}{\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]} \\\\\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = 1[/tex]
Hence the right answer is 1

Answer:
Step-by-step explanation:
I'm not sure but it might be because, while not in a vapor state yet, the molecules are moving faster as they get hotter and are getting closer to being a gas. Because they aren't vibrating in place anymore, they will need more room to more around. Again, I'm not positive but I think that this might work.

Is -2 a solution to x < -2? Is -2 a solution
to x < -2? Explain your answers.
Answer:
See below.
Step-by-step explanation:
x < -2 means that x is any number that is less than -2.
Is -2 less than -2? Answer: No.
A number is equal to itself. A number is not greater than itself or less than itself.
When the solution to an inequality is x < -2, the only values of x that are valid are numbers less than -2. -2 itself is not a valid solution.

Mathematics, 24.05.2020 00:00, aj2869 Franklin needs 1.25 meters of ribbon To wrap each gift. He had a spool of... Franklin needs 1.25 meters of ribbon To wrap each gift. He had a spool of ribbon that contains 25 feet of ribbon that contains 25 feet of ribbon. One meter is equivalent to approximately 3 feet. How many gifts of the same dimension can he wrap using the spool of ribbon
Answer:
He can wrap 6 gifts using the spool of ribbon
Step-by-step explanation:
Here, we want to know the number of gifts of the same dimension that Franklin can wrap using the spool of ribbon
Per gift 1.25m of ribbon is needed
Now in the spool, there is 25 feet of ribbon
1 m = 3 feet
x m = 25 feet
x = 25/3 meter
so the number of gifts of the same dimension he can wrap using the spool of ribbon will be;
25/3/1.25 = 25/3.75 = 6.67
Since he cannot wrap a gift fractionally, the number of gifts he can wrap is thus 6

Layla loves to try out new bike trails in her area. Last week, it took her 24 minutes to ride a trail that is 6 miles long. Today, she kept the same pace when she rode an 8-mile trail. How long did it take Layla to ride the trail today?
Answer:
32
Step-by-step explanation:
You have divided 24 and 6 to get 4
Then 8 - 6 is 2
2 x 4 is 8
and last 24 + 8 = 32
Hope this helped don't forget to mark brainliest☺️
Layla takes 32 minutes to ride 8-mile long trail.
Given Last week, Layla took 24 minutes to ride a trail that is 6 miles long.
So Speed of Layla to cover 6 miles is , [tex]\frac{6}{24} =0.25[/tex] miles per minute.
Now, Layla kept same speed of 0.25 miles per minute to rode 8-mile trail.
So, Time taken by Layla to cover 8 miles is [tex]\frac{distance}{speed}[/tex][tex]=\frac{8}{0.25} = 32[/tex] minutes.
Hence Layla takes 32 minutes to ride 8-mile long trail.

Jason is saving up to buy a digital camera that costs $490. So far, he saved $175. He would like to buy the camera 3 weeks from now. What is the inequality used to represent how much he must save every week to have enough money to purchase the camera?
Cost of Camera = $490
Money saved so far = $175
Money required to save in 3 weeks =490–175 =315
Let y represent the money to be saved and x represent the money to be saved per week
Then x = y/3 or 3x = y is the equation

You are making a banner from a piece of paper that is 11/12 feet long. You cut off a piece that is 1/4 feet long. How much paper is left to make the banner?
Answer:
2/3 feet
Step-by-step explanation:
Available length = 11/12 feet
Piece cut out = 1/4 feet
How much paper is left to make the banner?
Paper remaining = available length - piece cut out
= 11/12 - 1/4
= 11-3 /12
= 8/12
= 2/3 feet
Paper left to make the banner = 2/3 feet

The sum of 3 terms in A. P.is - 3 and their product is 8, then sum of squares of the numbers is
sum of the numbers = - 3
Product of the numbers = 8
Find:sum of squares of the numbers
Solution:Let the three terms be a - d , a , a + d.
sum of the numbers = - 3
→ a - d + a + a + d = - 3
→ 3a = - 3
→ a = - 3/3
→ a = - 1
Also,
Product of the numbers = 8
→ (a - d) * (a) * (a + d) = 8
Putting the value of a and using (a + b) * (a - b) = a² - b² we get,
→ [ (- 1)² - d² ] = 8/ - 1
→ 1 - d² = - 8
→ 1 + 8 = d²
→ 9 = d²
→ d = 3
Hence,
a - d = - 1 - 3 = - 4 a = - 1 a + d = - 1 + 3 = 2Now,
Finding Sum of their squares :
→ (a - d)² + a² + (a + d)²
→ ( - 4)² + ( - 1)² + (2)²
→ 16 + 1 + 4
→ 21
Hence, the sum of the squares of the three terms is 21.
I hope it will help you.
Regards.
