Step-by-step explanation:

A 45-45-90 triangle is a special type of isosceles right triangle that has angle measures of 45°, 45°, and 90°. Every 45-45-90 triangle has the same ratio of side lengths. If the legs of a 45-45-90 triangle are a, write an expression for the length of the hypotenuse.

Answers

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.

What is a triangle?

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.

Original price $69.80 with a 15% discount, what is the new price.

Answers

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.

If you have any questions, please let me know in the comments. If you could mark this answer as the brainliest, I would greatly appreciate it!

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

The base of the exponential function is 3.

How to identify the base?

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.

The size of your pool cover distance or area

Answers

Answer:

You solve this question

Step-by-step explanation:

Area = To work out the area of a square or rectangle, multiply its height by its width. If the height and width are in cm, the area is shown in cm².

Distance = It a numerical measurement of how far apart objects or points are.

Answer:

My pool's maximum depth: 6ft

My pool's full width: 10ft

My pool's full length: 12ft

(yea, it's pretty big!)

How do I find the area of my pool now?

First, let's start with the distance covered by the pool (area)

We can find that by just doing 10x12, which is 120

So, my pool's distance is 120ft²

EXTRA:

Now, the VOLUME of my pool...

we can find it by doing 6x10x12

6x10=60

6x12=72

60x12=720

So, my pool's VOLUME is 720ft.²

A bus leaves a bus station at 9:00 am and travels on the Eastbound Highway. A second bus leaves the same bus station 45 minutes later and travels in the same direction on the same highway at a speed of 20 kilometers per hour faster than the first bus. The second bus catches up with the first bus at 12:00. How fast was each bus traveling? (Include units in your answer. ) A. [3 pts) Define variables to represent the unknowns and setup the necessary equations to answer the question

Answers

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

Speed

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.
