Select the correct answer.
Consider the first four terms of the sequence below.
-3, -12, -48, -192, . . .
What is the 8th term of this sequence?
A.
-196,608
B.
-49,152
C.
-12,288
D.
-768
Answer:
D
Step-by-step explanation:
The value of 8th term of this sequence is,
⇒ a (8) = - 49,152
What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Given that;
Consider the first four terms of the sequence are,
⇒ -3, -12, -48, -192, . . .
Here, Common ratio is,
⇒ - 12 / - 3
⇒ 4
Thus, The sequence are in Geometric sequence.
Hence, The value of 8th term of this sequence is,
⇒ a (8) = - 3 × (4)⁸⁻¹
⇒ a (8) = - 3 × 4⁷
⇒ a (8) = - 3 × 16,384
⇒ a (8) = - 49,152
Thus, The value of 8th term of this sequence is,
⇒ a (8) = - 49,152

The temperature was less than -15°C. Write an equality and three possible solution.
Answer:
x < -15*C (I can’t make the degrees sign on my iPad, so I put * instead).
3 Possible Answers:
-38*C
-26*C
-57*C
Step-by-step explanation:
Inequality:
x = temperature
< = less than
-15*C = the amount the temperature was less than
3 Possible Outcomes:
Because the temperature is less than -15*C, it can literally be any number that is farther down the number line. Because it’s a negative number, anything like -14, -13, -12, and so on would actually have a greater value (think of it as in being less in debtm or in this case, less below zero). Instead, you’ll do any number like -16, -17, -18, and so on. You can even do a decimal number, like -19.5. I hope this makes sense to you!

75% as a fraction is 75/100, so 75 of the 100 swimsuits are bikinis.
Answer:
There are 75 bikini styles
Step-by-step explanation:
This is because 75% of 100 is 75 and if there are 100 different styles of swinsuits and 75% of them are bikinis then there are 75 different bikini styles

Answer:
I got 0.00001693508 is that one of your answers?
Answer is below. Look at the steps to understand the answer.
Step 1.We'll need to combine like-factors for (3⁻⁴ × 3⁻⁶)⁴.
To do that, we'll combine the exponents and copy the base number.
In the term, the like terms are...
3⁻⁴ and 3⁻⁶.
Like I said, when we need to combine the like-factors, we'll combine the numbers. Combine the numbers like this:
(3⁻⁴⁽⁻⁶⁾)⁴
Step 1a.Add the exponents.
Remember the integer rule.
P + P = P
N + N = N
P + N = P
P + N = N
According to the rule, a negative + negative = negative. So...
-4 + (-6) = (-10)
Step 2.We now need to make the exponent (3⁻¹⁰) positive.
Rule: A⁻ᴮ = ¹⁄ₐᴮ
According to the formula, A is the base number and B is the negative exponent.
That being said...
A → 3
B → 10
Now, since we know what A and B is, let's change our equation.
⅓¹⁰
Step 3Bring down the exponent 4 then multiply.
10 · 4 = 40
Therefore, the answer is ⅓⁴⁰.

Answer:
x = 5
Step-by-step explanation:
2x + 5 = 4x - 5First you will need to add 5 to each side.
2x + 10 = 4xThen you need to subtract 2x to each side.
10 = 2xLastly, you will need to divide each side by 2.
5 = xHave a nice day!Hurry 40 minutes left

You measure an obtuse angle on a protractor. If neither of the rays of the angle points at 0° or 180°, where could they point? Give the two points using degrees and explain why you chose those points.
Answer:
Any point greater Than 0 and less than 180°
Step-by-step explanation:
Obtuse angle measures are angles which measures angles in the range between 0° and 180°. Angles which lies between these range are called obtuse angles. Hence, from the question, if the ray of points measured does not point to 0° or 180°; then, the ray of angle points could have pointed to any angle between greater Than Zero less than 180.
Hence the points could 10 and 120 or any other values which meets the obtuse angle condition.
Answer:
173-degree angle (any angle larger than 90 degrees is obtuse and why are there favorite numbers all of a sudden????)
145-degree angle (there really is no reason to choose 2 certain numbers)
Step-by-step explanation:
any angle larger than 90 degrees is obtuse, so there you go my children.

A manager at a factory finds that in a random sample of 250 watches, 3 are defective. Of the 7,500 watches from which the sample was chosen, about how many watches are not defective?
Answer: 7410 watches
Step-by-step explanation:
From the random sample of 250 watches, 3 are defective. The percentage that's defective will be:
= 3/250 × 100
= 1.2%
Percentage that's not defective = 100 - 1.2 = 98.8%
Therefore, from the sample of 7500 watches, the number that's not defective will be:
= 98.8% of 7500
= 98.8/100 × 7500
= 7410
Therefore, 7410 watches aren't defective
