The speed of the first bus is 60 km/h while the speed of the second bus is 80 km/h.

Speed is the rate of change of distance with time. It is given by:

Speed = distance / time

Let a represent the speed of the first bus, and b represent the speed of the second bus.

b = a + 20

At 12:00, t = 3 hours, hence:

a = d/3

d = 3a

Also:

b = d/2.25

d = 2.25b

3a = 2.25b

3a = 2.25(a + 20)

a = 60

b = 60 + 20 = 80

The speed of the first bus is 60 km/h while the speed of the second bus is 80 km/h.

Answer:

$59.33

Step-by-step explanation:

To begin, let's start with what we know

Item = 69.80

Discount = 15% or 0.15

So, let's put it into this formula

New Price = Item ( 1 - Discount)              Note: P is the final price

                 = 69.80 ( 1 - 0.15)

                 = 69.80 ( 0.85 )

                 = 59.33

The new price is $59.33.

Answer:

$59.33

Step-by-step explanation:

To find the new price, we need to know what is 15% of 69.80, and then subtract the result from 69.80. To find the percent, we multiply the number by the percent using decimals for the percent. 15% is 0.15, so we multiply 69.80 * 0.15 = 10.47

Next, subtract 10.47 from 69.80.

69.80 - 10.47 = 59.33

The new price is 59.33.

Another method is that since 69.80 is 100 percent, then the new price will be 100% - 15% = 85%. Multiply the 85 percent by 69.80, and find your answer.

0.85 * 69.80 = 59.33

Answer:

Step-by-step explanation:

We need 2 people out of a group of 4

Let's take a random person, and another to group with the random person we picked. We can group them with 3 different people ( 3 ways )

Now, repeat again, and pick a person to group with the person who is grouped with the first person (except the first person themself) (2 ways)

And repeat again, you will group them with the last person.

So in total, you have 3 + 2 + 1 = 6 ways to pick 2 people from a group of 4.

The base of the exponential function is 3.

Here we have the graph of an exponential function of the form:

f(x) = b^x

We want to find the value of b.

Remember that any number with an exponent of 1 is equal to the number:

a^1 = a

Then, we will have:

f(1) = b^1 = b

If you look at the graph, you can see that when x = 1, the function is equal to 3.

Then:

f(1) = 3 = b

From this, we can conclude that the base is equal to 3.

Hello!

We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.

To solve, we just multiply the two probabilities.

=0.2125≈21.3

Therefore, we have about a 21.3% chance of this event occurring.

Answer:

[tex]a\sqrt{2} =h[/tex]

Step-by-step explanation:

The expression for the length of the hypotenuse is 2x.

Where x is any positive integer.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

An isosceles right triangle has angle measures of 45°, 45°, and 90°.

This means,

Two sides opposite to the equal angles are equal.

Now,

Equal sides = M

Hypotenuse sides = N

Now,

Every 45-45-90 triangle has the same ratio of side lengths.

This means,

Angles ratio:

45 : 45 : 90 = 1 : 1 : 2

Similarly,

Sides ratio:

M : M : N = 1x : 1x : 2x

Thus,

The expression for the length of the hypotenuse is 2x.

Where x is any positive integer.
