The answer is 2n - 8
Answer:
2n-8
Step-by-step explanation:
The expression eight less then twice a number will be shown in the following steps.
First, we tackle the first part of the sentence “Eight less” from here we can derive that there is a -8 in the expression.
Secondly, we can tackle the second part “twice a number” so this would be mean 2 times N, or 2n
From the two steps previously we can the conclude the answer must be 2n-8

Answers
Answer:
A
Step-by-step explanation
Dilation: A shape is scaled up or down by a scale factor
Translation: A shape is moved on a coordinate plane to a different spot.
A works because lets you one side (the bottom side). The bottom has a length of 3, and the bigger one has a length of 6, showing a scale factor of 2.

Answers
The volume of a cuboid is the product of its length, width, and height. The total volume with Selina is 360 in³.
What is the volume of a cuboid?The volume of a cuboid is the product of its length, width, and height. It is represented as,
[tex]\rm \text{Volume of Cuboid} = (Length \times Width \times Height)\ unit^3[/tex]
The volume of each of the boxes with a width of 6 in, a height of 3 in, and a length of 4 in, can be written as,
[tex]\rm \text{Volume of a single Box} = 6\ in \times 3\ in \times 4\ in = 72\ in^3[/tex]
Now, the total number of boxes Selina has is 5, therefore, the total volume with Selina can be written as,
[tex]\rm \text{Total\ Volume} = \text{Volume of a single box} \times 5 = 72\ in^3 \times 5 = 360\ in^3[/tex]

Step-by-step explanation:
t10=ar^9

s30=a(r^n-1)/r-1
=1000(2^30-1)/2-1
The geometric series given as 1000, 500, 250, 125,... is seen to be; Convergent.
What is divergent or convergent series?
A series is said to be divergent if it doesn't converge at any finite point. However, a series is said to be convergent if it converges at a finite point.
In this question, we see the series progressively reducing by one quarter of the previous number. Thus, it means that the sequence will converge close to zero and as such we can say taht the sequence is convergent.
Formula for sum of geometric series is;
Sₙ = a(1 - rⁿ)/(1 - r)
Thus;
S₁₀ = 1000(1 - 0.5¹⁰)/(1 - 0.5)
S₁₀ = 1998.05
Sum of first 30 terms is;
S₃₀ = 1000(1 - 0.5³⁰)/(1 - 0.5)
S₃₀ = 2000

A group of seven kids line up in a random order. Each ordering of the kids is equally likely. There are three girls and four boys in the group. What is the probability that all the girls are ahead of all the boys
Answers
Using the arrangements formula, it is found that there is a 0.0286 = 2.86% probability that all the girls are ahead of all the boys.
What is the arrangements formula?The number of possible arrangements of n elements is the factorial of n, that is:
[tex]A_n = n![/tex].
The total number of outcomes is the arrangement of 7 elements, hence:
T = 7! = 5040.
The desired number of outcomes is all girls(3!), then all boys(4!), hence:
D = 3! x 4! = 6 x 24 = 144.
Hence, the probability is:
p = D/T = 144/5040 = 0.0286.
There is a 0.0286 = 2.86% probability that all the girls are ahead of all the boys.

An inground swimming pool contains 2.3 times 10 superscript 4 units of water. which unit of measure was used? teaspoons cubic centimeters fluid ounces gallons
Answers
The measurement unit used for the water in the swimming pool is 2.3×10⁴ gallons.
What is the Unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimeter is equal to 10 mm,
Though the real measurement is still the same the units and numerical values have been changed.
As it is given, the pool's volume or the amount of water in the pool is equal to 2.3×10⁴ units.
We know that an average swimming pool has a volume of water that is in gallons, therefore, the unit of water that will be filled in the swimming pool will be equal to 2.3×10⁴ gallons.
Hence, the measurement unit used for the water in the swimming pool is 2.3×10⁴ gallons.
