The geometric series with 4th term as 10 and 7th term as 80 has the sum of the first tenth terms as 1278.75.

aₙ = arⁿ⁻¹

where

Therefore,

10 = ar³

80 = ar⁶

Hence,

a = 10 / r³

80 = (10 / r₃) r⁶

80 = 10r³

r³ = 80 / 10

r = ∛8

r = 2

a = 10 / 2³

a = 10 / 8 = 5 / 4

The sum of 10 terms can be calculated as follows:

Sₙ = a(rⁿ - 1) / r - 1

Sₙ = 5 / 4 (2¹⁰ - 1) / 2 - 1

Sₙ = 5 / 4 (1024 - 1) / 1

Sₙ = 1.25(1023)

Sₙ = 1278.75

Answer:

  a = √28

Step-by-step explanation:

The Pythagorean theorem tells you the area of the large square is the sum of the areas of the smaller two squares.

  8² = a² +6²

  a² = 8² -6² = 64 -36 = 28

Taking the square root, we find ...

  a = √28

Answer:

10x=480    (x=48)

30 people must show up  for the total cost per person to be $16

Step-by-step explanation:

p= people

10p = 480    

($10 multiplied by the number of people)   10p

p = 48

  48 people bought $10 entrance

     $16 multiplied by the number of people  =16p  

16p = 480

p = 30

 30 people must show up  for the total cost per person to be $16

Answer:

B

Step-by-step explanation:

Answer:

x=-2 or x=14

Step-by-step explanation:

since it's absolute value, this actually has two equations:

x-6=8

and

x-6=-8

we solve x-6=8 by adding 6 to both sides which equals x=14

we solve x-6=-8 by also adding 6 to both sides which equals x= -8+6= -2

The mathematical word describing  both 27x and 6x in the expression  is "addition" or "sum"

The mathematical expression is 27x + 6x.

Mathematical expression are combinations of numbers and variables ordered with operations.

Mathematical expression is a combination of numbers, variables, operators (such as addition, subtraction, multiplication or division etc.).

For the given case, the terms are 27x and 6x and the expression formed from them is 27x + 6x.

This simply implies both terms are summed together to give the expression 27x + 6x.

Therefore, the mathematical word describing  both 27x and 6x in the expression  is "addition" or "sum"

Step-by-step explanation:

Tn = a + (n - 1)d

n = 70, a = 17, d = > 20 - 17 => 3

T_70 = 17 + (70 - 1)3

T_70 = 17 + 69•3

9x² -9y²= 72

Factorise:

9(x² -y²)= 72

Divide both sides by 9:

x² -y²= 8

(x +y)(x -y)= 8

Given that x -y= 1.5,

(x +y)(1.5)= 8

Divide both sides by 1.5:

I believe that is it

Using a system of equations, it is found that the equation that could be used to find the value of b is given by:

3×4−8=b

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

Fatima has 3 packs of batteries. Each pack contains 4 batteries, hence:

b = 3 x 4

She gives her brother 8 batteries to put in his toy robot, hence:

b = 3 x 4 - 8

Which means that the first expression is correct.
