Logs are stored in apile of 20 rows,with each row having one fewer log than the one below it. If there is 48 logs on the bottom row how many logs are in the pile?

Answers

Answer 1

Answer:

754 logs

Step-by-step explanation:

If you are starting at 48 logs on the bottom row subtracting one log for each row you go up, then you should have 28 logs in the top row.

This is because 48-20=28

now you need to find the factorial of 48 starting at 28.

Factorial is like 1+2+3+4+5=15. So it is basically just adding every single whole number that are in between 2 whole numbers.

So for this equation you would need to do: 28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45+46+47+48= 754.

:) Hope that helped!

Answer 2

Answer:

770

Step-by-step explanation:

1st raw =a = 48

2nd raw = 47

.

.

d= -1 , n = 20

Summation S= n/2 [2a+(n-1)d]

= 20/2 [ 2×48 + (20-1)×-1]

= 770

Which function has the greatest constant of variation? A x 8 9 10 11 y 20 22.5 25 27.5 B x 1 2 3 4 y 3.2 6.4 9.6 12.8 C On coordinate plane C, a line goes through points (0, 0) and (3, 1). D On coordinate plane D, a line goes through points (0, 0) and (1, 2).

Answers

Answer:

the answer is b

Step-by-step explanation:

edge 2020

The function with the greatest constant of variation is function B, x: 1, 2, 3, 4, y: 3.2, 6.4, 9.6, 12.8.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The constant of variation (k) is calculated as k = Δy/Δx for two points on a line.

For Function B, k = (6.4 - 3.2)/(2 - 1) = 3.2, which is the greatest constant of variation among all the functions.

For Function A, x: 8, 9, 10, 11, y: 20, 22.5, 25, 27.5, k = (22.5 - 20)/(9 - 8) = 1.25.

For Function C, on the coordinate plane C, a line goes through points (0, 0) and (3, 1), k = (1 - 0)/(3 - 0) = 1/3.

For Function D, on the coordinate plane D, a line goes through points (0, 0) and (1, 2), k = (2 - 0)/(1 - 0) = 2.

Listen i know its dumb but-
solve for w
10 + w = -9

Answers

Answer:

w = -19

Explanation:

To solve this equation, subtract ten from both sides. This will isolate the variable (w) and allow us to find its value.

[tex]10 + w = -9\\(10 - 10) + w = (-9 - 10)\\w = (-9 - 10)\\w = -19[/tex]

If you would like to double check that the variable (w) does in fact equal negative nineteen, substitute the value of the variable in the equation and solve.

[tex]10 + w = -9\\10 + -19 = -9\\-19 = -19 [true][/tex]

Therefore, the value of w in the given equation is -19.

situation.

Answers

Answer:

The average inches of the height of the corn plants of variety A is 43.8 inches

Step-by-step explanation:

In mathematics or statistics, the mean refers to the average of numbers.

The mean is estimated by dividing sum of all the numbers by the count of the numbers.

For this question, the mean height of the corn plants of variety A of 43.8 inches is obtained as follows:

Sum of all the inches = 46 + 46 + 47 + 48 + 49 + 49 + 50 + 6 + 48 + 49 = 438 inches

Count of all the inches = 10

Mean = Sum of all the inches / Count of all the inches = 43.8 inches

The interpretation of this is that the average inches of the height of the corn plants of variety A is 43.8 inches.

A square patio has an area of 225 square feet. Write the area as a power.
Then find the side lengths of the patio.

Answers

Answer:
Write the area as a power: 15^2
Then find the sidelength of the patio: Each side is equal to 15

Reasoning:

A square has four equal sides and to work out area the formula is length x witdth, hence the length and width values are equal. This could also be written as length^2.

Since the area of the patio is 225, the square root of this would give each side length. Henceforth the square root of 225 is equal to 15. A square has four equal sides and to work out area the formula is length x witdth, hence the length and width values are equal. This could also be written as length^2.

∠A and \angle B∠B are complementary angles. If m\angle A=(8x+27)^{\circ}∠A=(8x+27)

and m\angle B=(6x-21)^{\circ}∠B=(6x−21)

, then find the measure of \angle B∠B.

Answers

Answer:

∠ B = 15°

Step-by-step explanation:

Complementary angles sum to 90° , that is

∠ A + ∠ B = 90 , substitute values

8x + 27 + 6x - 21 = 90

14x + 6 = 90 ( subtract 6 from both sides )

14x = 84 ( divide both sides by 14 )

x = 6

Thus

∠ B = 6x - 21 = 6(6) - 21 = 36 - 21 = 15°
