AUPH stock jumped up 60%, then down 60% did it return the same price

Mathematics
1 answer:
pshichka [43]3 years ago
8 0

Answer:

No, it didn't return to the same price

Step-by-step explanation:

Let the initial stock price be 100

When it increased by 60%, it went to:

60% = 60/100 = 0.6

0.6 * 100 = 60

100 + 60 = 160

Then, from 160, it decreased by 60%, so it went to:

60% = 0.6

So,

0.6 * 160 = 96

Now,

160 - 96 = 64

So final price is 64. So, it didn't go back to original (100).

Step-by-step explanation:

a. An image showing the step by step solution is attached.

b. P(Y > 2) = P(3) + P(4)

= 2/10 + 3/10 = 5/10 = ½

A number consists of two digits. The number is 2 more than 8 times the sum of the digits, and if 54 is subtracted from the numbe
Gennadij [26K]

Let the units digit = x

Let the 10s digit = y

Equations

10y + x - 2 = 8 * (x + y)              (1)

10y + x - 54 = 10x + y               (2)

Equation 1

10y + x - 2 = 8 * (x + y)    Remove the brackets on the right

10y + x - 2 = 8x + 8y       Subtract 8y from both sides

10y - 8y + x - 2 = 8x        Subtract 8x from both sides

2y + x - 8x - 2 = 0            Combine

2y - 7x - 2 = 0                  (3)

Equation 2

10y + x - 54 = 10x + y      Subtract 10x

10y - 9x - 54 = y              Subtract y from both sides.

9y - 9x - 54 = 0               Divide by 9

y - x - 6 =  0                     Multiply by 2

2y - 2x - 12 = 0                (4)

Solution

Subtract (3) - (4)

2y - 7x - 2 = 0

2y - 2x - 12 = 0

- 5x + 10 = 0      Subtract 10 from both sides.

- 5x = - 10          Divide by - 5

  x = 2

Use (4) to find y

2y - 2x - 12 = 0         Let x =2

2y - 2(2) - 12 = 0      Remove the brackets

2y - 4 - 12 = 0           Combine

2y - 16 = 0                 Add 16 to both sides.

2y = 16                      Divide by 2

y = 8

Answer 82

I'll leave the check to you, but the answer of 82 is correct.

Could someone help me please please I have only 2 tries please, please<br>and please explain
Leno4ka [110]

Answer:

<h2>84in²</h2>

Step-by-step explanation:

If the first one is 7 inches long, and 6 inches wide, and the second one is also 7 inches long, but is 6x2 inches wide, then what's the area?

6x2=12

So, Picture Frame 2 = 12 inches wide

Formula for finding area = LxW

L = 7

W = 12

7x12=84

So hence, your answer is 84in²

The area of the second frame is 84in²

Thanks!
