Rini used a stick to draw a right triangle in the ground. The hypotenuse of her triangle is 24 inches and one of the legs is 12

Mademuasel [1]

Use the pythagorean theorem A² + B² = C²

A and B are legs and C is the hypotenuse

so- A² + 12² = 24² A² + 144 = 576
-144 -144

A² = 432 then you have to take the square root
of each side

so- A = √432 or aprox. 20.78

Given the system of equations, what is the x-coordinate of the solution?

Nimfa-mama [501]

Answer: Choice C) -11

-----------------------------------

Explanation:

The first equation given is y = 3 - 1/2x
In other words, y is the same as 3 - 1/2x.
We can replace y in the second equation with 3 - 1/2x
This is known as substitution (think of a substitute teacher who is a temporary replacement for your teacher)

Doing this leads to...
3x+4y = 1
3x+4*y = 1
3x+4*( y ) = 1
3x+4*( 3 - 1/2x ) = 1 <<--- y has been replaced with 3-1/2x
3x+4*(3) +4*(-1/2x) = 1
3x+12-2x = 1
3x-2x+12 = 1
x+12 = 1
x+12-12 = 1-12 <<-- subtracting 12 from both sides
x = -11
Which is why the answer is choice C) -11

You are thinking about the things that can go wrong on your trip home over the Thanksgiving break. You have booked a flight with

shtirl [24]

Answer:

The probability that the person reaches home for the holidays is 0.94.

Step-by-step explanation:

A person wants to go home for Thanksgiving and he has booked a flight with US-Scareways.

It is provided that in 30 percent of the cases the company has canceled the flight you were on.

SO there is 70% chance of reaching home without any difficulties.

In case the flight is cancelled, then as a backup the person's friend Walter offers a ride home.

Walter also has a 80% chance of giving the ride. So there is 20% chance the person will not be able to reach hone if his flight gets cancelled.

Consider the tree diagram below.

The events are:

FC = flight is cancelled

FT = Flight is on time

H = reaches home

Compute the probability that the person reaches home as follows:

P (Reaching Home) = P (H|FC) × P (FC) + P (FT)

$=(0.80\times 0.30) +0.70\\=0.24+0.70\\=0.94$

Thus, the probability that the person reaches home for the holidays is 0.94.

0.09 = 0.00 because 0 in the tenths is nearer to the 0 than the next number or digit :)
