Answer:

36 km

By dividing 45 by 60 you make it into .75 per minute therefore by multiplying by 48 you get your answer which is 36 km

Answer:

36 km

Step-by-step explanation:

We are given a speed in km per hour. Since 1 hour = 60 minutes, we can find the speed in km per minute.

45 kph = 45 km/hour = 45 km/(60 minutes) = 0.75 km/minute

Now that we know the speed in km per minute, we multiply the speed by 48 minutes to find the distance traveled in 48 minutes.

0.75 km/minute * 48 minutes = 36 km

Solve this inequality for x: -46 -8x >22.

olga2289 [7]

Answer:

Step-by-step explanation:

The key to answering this is to know that the only time you'll change the direction of the sign is when you multiply or divide by a negative number.

-46 - 8x > 22

-8x > 22 + 46

-8x > 68

x < 68/-8 (we divided by -8 so the inequality changed direction)

x < -17/2

An acorn falls from the branch of a tree to the ground 25 feet below. The distance, S, that the acorn is from the ground as it f

Hunter-Best [27]

Answer:

$0$

Step-by-step explanation:

We are given that,

The fall of the acorn is represented by the function,

$S(t) =-16t^2+25$

Equating S(t) to 0 gives,

$0=-16t^2+25$

i.e. $16^2=25$

i.e. $t^{2}=\frac{25}{16}$

i.e. $t=\pm \frac{5}{4}$

Since, time cannot be negative.

So, $t=\frac{5}{4}$ i.e. 1.25 seconds is the time when the acorn will reach the ground.

Thus, from the figure below, we see that,

The interval in which the acorn is in the moving air is $0$ .

ATM personal identification number (PIN) codes typically consist of four-digit sequences of numbers. Find the probability that i

oksian1 [2.3K]

Answer:

(a) 0.0001 or 0.01%

(b) 0.01 or 1%

Step-by-step explanation:

Since there are 10 possible numeric digits (from 0 to 9), and there is only one correct digit, there is a 1 in 10 change of getting each digit right.

The probability that if you forget your PIN, then you can guess the correct sequence

(a) at random:

$P=(\frac{1}{10})^4=0.0001=0.01\%$

(b) when you recall the first two digits.

$P=(\frac{1}{10})^2=0.01=1\%$
