Find the value of X in the image above.

zaharov [31]

Answer:

58°

Step-by-step explanation:

$(x + 6) \degree + 2x \degree = 180 \degree..(straight \: line \: \angle s) \\ \\ (3x + 6) \degree = 180 \degree \\ \\ 3x + 6 = 180 \\ \\3x = 180 - 6 \\ \\ 3x = 174 \\ \\ x = \frac{174}{3} \\ \\ \huge \red{ \boxed{ x = 58}}$

A standard deck of cards has 52 cards, 4 of each type (Ace, King, Queen, Jack, 10,...,2). From a well-shuffled deck, you are dea

Wewaii [24]

Answer:

a)%85,5

b)%92,2

Step-by-step explanation:

a) To determine the probability of getting a hand with at least one face, we need to calculate the probability of the hand without any face firstly.

$(36/52)*(35/51)*(34/50)*(33/49)*(32/48)=0,145$

Then, we need to deduct this value from the probability 1

$1-0,145=0,855$

The probability of the hand with at least one face is %85,5.

b)To determine the probability of a hand with at least one ace and face we will track the same road again.

$(32/52)*(31/51)*(30/50)*(29/49)*(28/48)=0,0775$

Then, we need to deduct this value from the probability 1

$1-0,0775=0,922$

The probability of the hand with at least one ace and one face is %92,2.

The summer has ended and it’s time to drain the swimming pool. 20 minutes after pulling the plug, there is still 45 000L of wate

WITCHER [35]

Answer:

a) -900 L/min

b) 63000 L

c) v = -900t +63000

d) 7200 L

Step-by-step explanation:

a) You are given two points on the curve of volume vs. time:

(t, v) = (20, 45000) and (70, 0)

The rate of change is ...

Δv/Δt = (0 -45000)/(70 -20) = -45000/50 = -900 . . . . liters per minute

b) In the first 20 minutes, the change in volume was ...

(20 min)(-900 L/min) = -18000 L

So, the initial volume was ...

initial volume -18000 = 45000

initial volume = 63,000 . . . . liters

c) Since we have the slope and the intercept, we can write the equation in slope-intercept form:

v = -900t +63000

d) Put the number in the equation and do the arithmetic.

When t=62, the amount remaining is ...

v = -900(62) +63000 = -55800 +63000 = 7200

7200 L remain after 62 minutes.
