Answer:

9

Step-by-step explanation:

The ladder is the hypotenuse, the wall is one of the legs. In order to find the other leg you have to do c^2-a^2=b^2. 41^2-40^2 is 81 and the square root of that is 9

Answer: 9 feet.

Step-by-step explanation: You can use the Pythagorean Theorem to solve this. If the hypotenuse of the triangle = 41, and one of the legs = 40, you can solve this equation:

41^2 = 40^2 + b^2

1681 = 1600 + b^2

81 = b^2

9 = b

6x – 4y = -5<br>4x + 5y = -11​
kipiarov [429]

Answer:

x= -1.5, y= -1

Step-by-step explanation:

6x= -5+4y

x= (-5+4y) / 6

4((-5+4y) / 6) + 5y = -11

4(-5+4y) + 5*6y = -11*6

-20+16y+30y= -66

16y + 30y = -66+20 = -46

y(16 + 30) = -46

y= -46 / (16 + 30)

y= -46 / 46

y= -1

x= (-5+4(-1)) / 6

x= (-5-4) / 6

x= -9 /6

x= -1.5

Tpy6a [65]

Answer:

Audrey was charged $3 for each withdrawal.

Step-by-step explanation:

We have to calculate the amount of money charged on one transaction.

In order to find the amount for one ATM withdrawal, the total amount for ATM withdrawals will be divided by number of withdrawals.

Given

Total\ ATM\ withdrawal\ fees = \$51\\Total\ withdrawals = 17\\Amount\ for\ one\ withdrawal = \frac{Total\ fees}{No.\ of\ withdrawals}\\= \frac{51}{17}\\= \$3

Hence,

Audrey was charged $3 for each withdrawal.
