find the 29th term of the arithmetic sequence 182,176,170

Answers

9514 1404 393

Answer:

Step-by-step explanation:

The first term of the sequence is 182, and the common difference is 176-182=-6. So, the general term is ...

an = a1 +d(n -1)

an = 182 -6(n -1)

The 29th term will be ...

a29 = 182 -6(29 -1)

a29 = 14

For what value of x is the given parallelogram a
rhombus?
(6x +13)
(9x-5)
The given parallelogram is a rhombus when x=

Answers

Answer:

x = 6

Step-by-step explanation:

(9x - 5)° = (6x +13)°

9x - 5 = 6x + 13

9x - 6x = 13 + 5

3x = 18

x = 18/3

x = 6

The given parallelogram is a rhombus when x = 6

The value of 'x' for which the parallelogram will be a rhombus is x = 3.

What is a rhombus?

A quadrilateral with all equal sides is a rhombus.

Rhombuses are a particular kind of parallelogram in which all of the sides are equal since the opposite sides of a parallelogram are equal.

A rhombus has 360° of interior angles total.

A rhombus's adjacent angles add up to 180°.

A rhombus's diagonals are perpendicular to one another and cut each other in half.

One more property of rhombus is that the diagonals bisect the originating angles.

Therefore, The values of 'x' for which this parallelogram will be a rhombus is, 6x + 13 = 9x - 5.

6x - 9x = - 5 - 13.

- 3x = - 18.

3x = 18.

x = 6.

10. Harmony places the letters in the word DECEMBER into a bag. A letter will be randomly
selected and not replaced. Then another letter will be selected. What is the probability of
Hormony selecting a C and then an E?

Answers

Answer:

3/56

Step-by-step explanation:

There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to [tex]\frac{1}{8}[/tex] times [tex]\frac{3}{7}[/tex], which is equal to [tex]\frac{3}{56}[/tex].

Step-by-step explanation:

let a bag of popcorn be represented by p and a candy bar be b

28p + 40b= $282

17p + 20b= $160.50

this is an example of stimatanelous equations

so you have to double the second equation to give 34p + 40b =$321

subtract the equations to give one

6p =$39

divide $39 by 6 to give the value of one bag of popcorn = $6.50
