Answer: D
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the arithmetic sequence:
10, 12, 14, 16, ...
Where a1=10 and
r = 12 - 10 = 2
Thus the general term is:
[tex]a_n=10+(n-1)2[/tex]
Operating:
[tex]a_n=10+2n-2[/tex]
[tex]a_n=8+2n[/tex]

The city of Stockport received 24 inches of rain last year.
One-fourth of it came in November, and one-third of it came in March.
How much rain came during the other 10 months of the year?
Answers
Answer:
5/12 of rain came, or 10 inches
Step-by-step explanation:
complete rain be 1
then, =1-(1/4+1/3)
=1-(3+4/12) take lcm
=1-7/12
=12-7/12 again lcm
= 5/12
or
1/4 of 24 inches means 1/4×24= 6 inches
1/3 of 24 inches, then 1/3×24= 8 inches
therefore, rest of the months get
= 24-(6+8)
=24-14
=10 inches

-La altura de una caja es el cuádruple de su ancho y de su largo.
-Si su volumen es de 500 cm3
- ¿Cuáles son las dimensiones de la caja?
Answers
Answer:
Las dimensiones de la caja son:
ancho: 5 cmlargo: igual al ancho: 5 cmaltura: 20 cmStep-by-step explanation:
Un prisma es un poliedro que consta de dos caras iguales y paralelas llamadas bases, y de caras laterales que son paralelogramos. En el caso en que las caras laterales sean rectangulares, se llama prisma rectangular.
El volumen de la caja, un prisma restangular, se calcula como el área de la base multiplicado por la altura. El área de la base se halla por la fórmula del área del cuadrado: lado multiplicado por lado, es decir, ancho por largo.
En este caso:
ancho: xlargo: igual al ancho= xaltura: cuádruple de ancho y largo= 4*xEntonces:
Volumen=x*x*4*x
Volumen=4*x³
Si su volumen es de 500 cm³, entonces:
500 cm³=4*x³
Resolviendo:
[tex]x^{3} =\frac{500 cm^{3} }{4}[/tex]
x³= 125 cm³
x=∛125 cm³
x= 5 cm
Entonces, las dimensiones de la caja son:
ancho: 5 cmlargo: igual al ancho: 5 cmaltura: 4*5cm= 20 cm(x² – 2x - 4) (x² – 3x-5)

The solution is Option C.
The area of the rectangle is given by the equation A = 1/4 feet²
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the rectangle be represented as A
Now , the equation will be
Let the length of the rectangle be L
The value of L = 5/8 feet
Let the width of the rectangle be W
The value of W = 4/9 feet
Area of Rectangle = Length x Width
The measure of Length L = 5/8 ≈ 1/2
The measure of Width W = 4/9 ≈ 1/2
Substituting the values in the equation , we get
Area of Rectangle A = 1/2 x 1/2
Area of Rectangle A = 1/4 feet²
Therefore , the value of A is 1/4 feet²
Hence , the area of rectangle is 1/4 feet²

P(x) 3/17 5/17 6/17 2/17 1/17
Answer:
1.59 ; 1.09
Step-by-step explanation:
The Mean :
E(X) = Σx*p(x)
(0*3/17) + (1 * 5/17) + (2*6/17) + (3*2/17) + (4*1/17)
= 1.58823
= 1.59
Standard deviation = sqrt(Var(x))
Var(X) = Σx²*p(x) - E(x)²
= {(0^2*3/17) + (1^2 * 5/17) + (2^2*6/17) + (3^2*2/17) + (4^2*1/17)} - 1.59^2
= 3.7058823 - 2.5281
= 1.1777823
Standard deviation = sqrt(1.1777823)
= 1.0852567
= 1.09

If 1/2 of a gallon of paint covers 1/8 of a wall, how much paint is need to cover the entire wall?
Answers
Answer:
4 gallons
Step-by-step explanation:
multiply 1/2 by 8 to find the number
Answer:
One gallon of paint can cover [tex]\frac{1}{4}[/tex] of a wall.
Step-by-step explanation:
start by writing the ratio:
[tex]\frac{1}{2\\}[/tex] : [tex]\frac{1}{8}[/tex]
There are two halfs in one gallon so you multiply the [tex]\frac{1}{2\\}[/tex] by 2. And whatever you do to one side must be done to the other so:
[tex]\frac{1}{2\\}[/tex]×2 : [tex]\frac{1}{8}[/tex]×2
Evaluate.
1: [tex]\frac{2}{8}[/tex]
this can be further simplified to
