what is the common ratio! HELP ASAP

Answers

Answer 1
Answer: Answer: The common ratio is -1/3

-----------------------------------------------------------

Work Shown:

Pick any term to divide it by the previous term. I'm going to pick the second term and divide it by the first term.

r = common ratio
r = (term 2) divided by (term 1)
r = (4/9) divided by (-4/3)
r = (4/9) * (-3/4) 
r = (4*(-3))/(9*4)
r = -12/36
r = -1/3
The common ratio is -1/3

This means you multiply each term by -1/3 to get the next term

For instance
term 2 = r*(term 1)
term 2 = (-1/3)*(-4/3)
term 2 = ((-1)*(-4))/(3*3)
term 2 = 4/9

What is the solution of the system defined by y = -x + 5 and 5x + 2y = 14?Ax=1/3, y=11/7
Bx=4/3, y=11/3
Cx=5/11,y=0
Dx=4/3,y=1

Answers

y = -x + 5
5x + 2y = 14

5x + 2(-x+5) = 14
5x - 2x + 10 = 14
3x = 14 - 10
3x = 4
x = 4/3 or 1 1/3

y = -x + 5
y = -4/3 + 5
y = -4/3 + (5 * 3/3)
y = -4/3 + 15/3
y = -4+15 / 3 
y = 11/3 or 3 2/3

Correct answer is B. x = 4/3 ; y = 11/3

Martin burns 360 calories running for 30 minutes. Paul burns 165 calories for every 15 minute he runs. If Kara runs for 20 minutes, how many calones would she have to burn to have a rate calories burned per minute of running that is between Martin and Paul? Please explain and give evidence.​

Answers

Answer:  She would have to burn between 220 and 240 calories per minute to have a calorie burn rate between those of Martin and Paul.

Step-by-step explanation:

Martin:

360 calories / 30 min = 12 calories/min

Paul:

165 calories / 15 min = 11 calories/min

Kara:

Needs to burn between 11 and 12 calories/min, so we'll calculate the range:

11 calories/min x 20 min = 220 calories (minimum # calories she can burn)

12 calories/min x 20 min = 240 calories (maximum # calories she can burn)

Ten weeks ago Jerry bought stock at 211/2
; today the stock is valued at 203
/8
. We could say the stock
is performing at which of the following?
A. On par
B. Par equality
C. Below par
D. Above par

Answers

Since 211/2 = 105.5 and 203/8 = 25.375, it is quite clear that Jerry has lost money on this stock. So the correct answer is C. Below par.

Answer:

(c) Below par

Step-by-step explanation:

Ratio at which stock is bought = 211/2

                                                   = 105.5

Therefore, the par value = 105.5

Recent ratio of stock = 203/8

                                   = 25.375

Value of stock today = 25.375

Since the ratio is decreased Hence, the value of stock is below par value.
