this is a 45-45-90 triangle, what is the measure of x? rationalize the denominator

A triangle has all three angles summing up to 180. If two of the sides measure 40 degrees and 50 degrees, then the third side measures as follows;

The third angle, which is labelled as angle A measures 90 degrees, and that means the triangle is a "right angled triangle."

Answer:

Explanation:

To evaluate the difference:

First, rewrite the expression in the form below:

Next, factor out the powers of 10.

Thus, the difference written in scientific notation is:

Note: A number is in scientific notation if it is expressed as a product of a number (between 1 and 10) and a power of 10.

Solution:

Remember the following formula :

P(AUB) = P(A)+P(B)-P(AnB)

According to the data of the problem and applying the previous equation, we obtain the following equality:

This is equivalent to:

solving for P(A n B), we get:

so that, we can conclude that the correct answer is:

Speed of light = 300,000 km/sec

Rocket's speed = 63,000 km/hr or 6.3 x 10⁴ km/hr

Alpha Centauri distance from Earth = 4.11 x 10¹³ km

One light year (distance) = 9.46 x 10¹² km

To solve for the time it takes it travel, we can manipulate the speed formula.

We already have the distance of Alpha Centauri from Earth written above. We also have the speed of the rocket written above too. We will substitute those values to the formula.

In this problem, we have a continuous exponential growth model

so

the equation is of the form

where

a is the initial value ------> a=2,100

y is the number of bacteria

x ----> number of hours

so

For x=2.5 hours, y=2,249 bacteria

substitute

solve for k

apply ln both sides

k=0.0274

convert to percentage

Since the percent grade in period 1 was 92% and in period 2 was 96%, then the percent change from period 1 to 2 was 4%.

Since the percent grade in period 2 was 96% and in period 3 was 99%, then the percent change from period 2 to 3 was 3%.

Since 4% is 1% greater than 3%, then the percent change from grading period 1 to 2 was 1% greater than the percent change from grading period 2 to 3.

Therefore, the answer is: 1.0%.

The possible values of the expression 1/a = 1/2 is 2

The expression is the simple fraction form = 1/a

The expression is the defined as the a sentence with a minimum of two  variables and at least one math operation.

The simple fraction is fraction that contains the numerator and denominator as whole number. The term one the top of the simple fraction called as the numerator and bottom term is called as the denominator.

Here it is given that

1/a = 1/2

Therefore the value of a = 2

Hence, the possible values of the expression 1/a = 1/2 is 2

Answer:

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer:

0, 150, 100, 50 |    T=200-50x

Step-by-step explanation:

     So you start with 200 miles to go and you are going 50 miles per hour. In the first hour, 50 miles would have been completed meaning that you subtract 50 miles from the remaining distance. Same with the other hours.

     To put that in an equation, You would start with 200 and for every hour(x)you would subtract 50.

The first person to choose a seat can choose any of the 6 seats.

The second person can choose any of the 5 remaining seats.

The third person can choose any of the 4 remaining seats.

The fourth person can choose any of the 3 remaining seats.

Now, we do 6 x 5 x 4 x 3 to figure out the total number of ways they can sit in the seats.

6 x 5 x 4 x 3 = 360 ways

Step 1: Simplify both sides of the inequality.

12x+36>4x−8

Step 2: Subtract 4x from both sides.

12x+36−4x>4x−8−4x

8x+36>−8

Step 3: Subtract 36 from both sides.

8x+36−36>−8−36

8x>−44

Step 4: Divide both sides by 8.

8x/8 > -44/8

From science, we understand that engaging in exercise helps internal organs to function better. These are the sources of endurance

Exercising for a couple of more times, all things being equal means there will be more endurance. We can largely say that, for most people, it is expected that the higher the number of time spent exercising, the higher the endurance being built

Thus, we can conclude there is a positive correlation between the two

By taking x as a common factor we get:

2x - 1 + 3x = 0

(2 + 3)*x - 1 = 0

5x - 1 = 0

Let's start with equation A, it is:

2x - 1 + 3x = 0

If we group like terms, we will get:

(2x + 3x) - 1 = 0

Now we can take x as a common factor in the left term, so we get:

(2x + 3x) - 1 = 0

(2 + 3)*x - 1 = 0

Now we simplify the sum in the left term:

(2 + 3)*x - 1 = 0

5x - 1 = 0

This is equation B.
