The value of the given series is 49.75

Step-by-step explanation:

This is a problem from geometric progression ,

Where , a₁ is the first term and r is the ratio , and n is the number of terms.

Ratio is , 40/80 = 1/2

Here , a₄ = 80 . (1/2)⁴ ⁻ ¹ = 80 / 8  = 10

a₅ = 80 . (1/2)⁵ ⁻ ¹ = 80 / 16 = 0.5

a₆ = 80 . (1/2)⁶ ⁻ ¹ = 0.25

a₇ = 80 . (1/2)⁷ - ¹ = 0.125

Suppose B is the midpoint of -AC . Use the given information to find the missing measure. A B=6 y-14, B C=10-2 y, A C= ?

Answers

If AB = 6y - 14, BC = 10 - 2y then the value of AC = 8.

What is meant by midpoint?

In geometry, the midpoint is the point in the middle of a line segment. It is equidistant from both endpoints and serves as the segment and endpoint centroid. It cuts the segment in half.

Given: AB = 6y - 14, BC = 10 - 2y

Since B is the midpoint of AC, AB = BC then

6y - 14 = 10 - 2y

Add 14 on both sides of the equation, and we get

6y - 14 + 14 = 10 - 2y + 14

6y = - 2y + 24

Add 2y on both sides of the equation

6y + 2y = - 2y + 24 + 2y

simplifying the above equation, we get

8y = 24

y = 24/8

y = 3

Substitute the value of y in AC then we get

AC = 2(6(3) - 14)

= 2(4)

AC = 8

Therefore, the value of AC = 8.

Answers

The absolute value equation used to solve this problem: | x - 82 | = 12, where x = grade.

What is an absolute value equation?A statement that contains an absolute value is known as an absolute value equation. The absolute value contains the variable of the equation.

Now,

Given:

The average of grades = 82%Variation = 12%

Let 'x' be the value that gives the value of grades.

The absolute value equation to find the grades will be given by: | x - 82 | = 12

=> x - 82 = ± 12

For maximum value of the grades, x - 82 = 12

=> x = 82 + 12

=> x = 94.

For minimum value of the grades, x - 82 = -12

                       c = intercept

We have been given the equation that is,

Which square does not touch one of the perimeter squares?

The perimeter squares are the outer squares of the image. So, the only square that does not touch one of the perimeter squares is the central one. To identify it, you need to first see in which row it is, and you can see that it is row 3.

Then you need to identify the column, the central square is in column C.

Then the square that does not touch one of the perimeter squares is the square 3C.

What is the combined area of rows 4 and 5?

Let's say that each square has an area of one unit. Now, we have 5 columns, then each row has 5 squares, then the area of each row is 5 units.
