4. The time taken for passengers to be checked-in for a flight is inversely proportional

Mathematics
1 answer:
Alla [95]3 years ago

Answer:

90minutes

Step-by-step explanation:

Let the time taken for passengers to be checked-in be t

Let the number of staff working be w;.

If the time taken for passengers to be checked-in for a flight is inversely proportional to the number of staff working then;

t = kw

when t = 30, w = 5

30 = 5k

k = 30/5

k = 6

to get t when w = 15

t = kw

t = 6(15)

t = 90minutes

Hence it will take 90minutes long

The required probability for three numbers rolled on the dice are the sides of a triangle is 31/36.

<h3>What is probability?</h3>

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability.

Here,

When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).

Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.

As a result, 186 outcomes or triplets are possible and satisfy this property.

Hence, the required probability is 186/216=31/36.

The required probability is 31/36 for three dice rolls to produce triangle sides.

A 20-foot ladder is leaning on a
Gwar [14]

Answer:

From the bottom of the building to the top of the ladder, it is 16 feet.

Step-by-step explanation:

Depending on what grade you are in, you might know the Pythagorean theorem, whose equation is a^2+b^2=C^2 The measurement of the leaning ladder (20ft) is the hypotenuse of the right triangle, the distance from the bottom of the ladder to the building is the leg length (12ft). With this information we know the "c" of the equation, and the "b" or "a" of the equation. If we plug in the number for the letter the equation will look like this:  

12^2+b=20^2. 20 to the second power is 400, and 12 to the second power is 144. You can use the subtraction property of equality and get b^2=256. Use can use a calculator for this part. The square root of 256 is 16, which leaves the equation with b=16
