What are the steps i need to do (along with the answer) to 9^x = sqrt of 729?

Answers

Answer:

last option is correct 3/2

Answer:

x = 3/2

Step-by-step explanation:

9^x = 729 ^ 1/2

We need to get the bases the same

729 = 9^3

9^x = 9^3 ^ 1/2

We know that a^b^c = a^(b*c)

Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution. 5x + 6y = 1; - 5x - 8y = 2

Answers

Answer:

One solution

Step-by-step explanation:

Hi there!

We are given this system of equations:

5x+6y=1

-5x-8y=2

And we want to see how many solutions the equation has.

Let's solve the system in order to see how many solutions it has

Let's solve this system by elimination, where we will clear one variable by adding or subtracting the equations, solve for the other variable which wasn't cleared, and then use the value of the un-cleared variable to find the value of the variable we cleared earlier.

In order to clear a variable, the coefficients in front of those variables need to be opposites of each other (ex. if we wanted to clear y, the coefficients in front of y need to be -2 and 2 respectively). In this case, the coefficients in front of x are 5 and -5, so we can immediately add the equations

Add both equations together

-2y=3

Divide both sides by -2

y=-3/2

Now substitute -3/2 as y in either one of the equations to solve for x

If we were to do it in 5x+6y=1 for instance:

5x+6(-3/2)=1

multiply

5x-9=1

add 9 to both sides

5x=10

divide both sides by 5

x=2

So we solved the system and got x=2, y=-3/2 (or as a point, (2, -3/2)). This is the point of intersection of the two equations (in case you didn't notice, the equations are actually linear equations written in standard form). This is the ONLY point at which the lines will intersect.

Therefore, the system has one solution.

Hope this helps!

Answers

Answer:

30°

Step-by-step explanation:

As the chord has same length of radius, the chord and the two radius form a equilateral triangle. Each angle of triangle is 60.So the chord subtended  at the center is 60. So the angle subtended at the remaining part of the circle = 30°

The measure of angle between the tangent and chord = 30  {Alternate segment theorem}

Answer:

Step-by-step explanation:

I posted a picture at the bottom of the post that you need to look at in order to understand this problem. I labeled everything inside that circle and then created a triangle. That triangle is made up of 3 sides that are all the same length, and that length is the length of the radius. By definition, if a triangle has all 3 of its sides the same length, it is equilateral. It is also equiangular. That means that every angle inside that triangle measures 60 degrees. The central angle, the one that comes off the center, intercepts an arc. The arc measure is the same measure as this angle, so the intercepted arc measures 60 degrees. To find the measure of the angle in question, the one you need that is labeled with a pink θ, has a rule that says the angle is going to be half the measure of the intercepted arc. That means that your angle is going to measure 30 degrees.

Step-by-step explanation:

In a basketball tournament, Team A scored 5 fewer than twice as many points as Team B. Team C scored 80 more points than Team B. The combined score for all three teams was 983 points. Write an equation to represent this scenario using the variable b to represent Team B's total points. Translate the scenario.

Answers

Answer:

(2b - 5) + b + (b + 80) = 983

Step-by-step explanation:

Given that,

Total score of three teams = 983

Since the teams' scores are given in reference to team B's score, let 'b' be the score of team B.

So,

The scores of Team A = (2 * b) - 5

The scores of Team B = b

The scores of Team C = (b + 80)

Thus,

The equation for determining the total points of Team B would be:

(2b - 5) + b + (b + 80) = 983

On solving,

(2b - 5) + b + (b + 80) = 983

⇒ 2b + b + b = 983 + 5 - 80

⇒ 4b = 908

⇒ b = 908 ÷ 4

⇒ b = 227

Team B's score = 227

Team A's score = (2 * 227 - 5)

= 449

Team C's score = 227 + 80

= 307

Total ⇒ 449 + 227 + 307 = 983

Hence proved.

Explain why you made your choices. Why does one measurement need to be more precise than the other?

Answers

An example of a measurement that requires high precision or a low level of uncertainty is the length of a silicon microchip. One example of a measurement that can have lower precision or a higher level of uncertainty is the temperature of a room.

Precision and Measurement

One example of a measurement that requires high precision or a low level of uncertainty is the length of a silicon microchip. In the field of electronics manufacturing, even small variations in the length of a microchip can have significant impacts on its performance.

Therefore, it is essential to measure the length of a microchip with high precision, such as down to the nanometer scale, to ensure its functionality and reliability.

On the other hand, an example of a measurement that can have lower precision or a higher level of uncertainty is the temperature of a room. While temperature control is crucial in certain environments, such as a laboratory or a data center, in most cases, a general estimate of the temperature is sufficient.

A variation of a few degrees Celsius is unlikely to cause significant problems, making it unnecessary to measure the temperature with high precision.

The level of precision required for a measurement depends on the nature of the object being measured and the context in which the measurement is taken. In the case of the microchip, the manufacturing process is highly precise, and even small variations can lead to significant problems.

Therefore, it is essential to measure the length of the microchip with high precision. On the other hand, in the case of room temperature, the impact of small variations is usually insignificant, so a lower level of precision is acceptable. Overall, the precision required for a measurement depends on the importance of the measurement's accuracy and the potential consequences of imprecision.

2. Area of a rectangle is length (L) times height (H), so in this case, it would be (H) x (2H - 5)
3. Multiply H by everything in the parenthesis
4. You should get 2H^2 - 5H

The length L of the base of a rectangle is 5 less than twice its height H. Then the algebraic expression be, area of rectangle = 2H² - 5H.

What is the algebraic expression to model the area of the rectangle?

Let, the given information be "The length L of the base of a rectangle is 5 less than twice its height H".

L be the length of the rectangle

H be the height of the rectangle

By converting the given information into an algebraic expression, we get

Length = 2H - 5

The area of a rectangle is given by the formula;

Area of rectangle = L [tex]*[/tex] H

Where L is the Length.

H is the Height.

Substituting the values into the formula, we have;

Area of rectangle = (2H - 5) [tex]*[/tex] H

Area of rectangle = 2H² - 5H

8. In an examination 40% of the students failed. The number of students that passed was 180. How many students failed?
A.120 B.270

C.300 D.450​

Answers

Answer:

A

Step-by-step explanation:

Given 60% of students passed , then 40% of students failed.

60% = 180 ( divide both sides by 60 )

1% = 3

Then

40% = 40 × 3 = 120

120 students failed the exam

If the number of students that passed was 180, the number of students who failed the examination is 120. So, correct option is A.

To determine the number of students who failed the examination, we need to find 40% of the total number of students.

We are given that 40% of the students failed, which means that 60% of the students passed. Since we know that the number of students who passed is 180, we can set up the following equation:

60% of total students = 180

To solve for the total number of students, we divide both sides of the equation by 60% (or 0.6):

Total students = 180 / 0.6

Calculating the right-hand side of the equation, we get:

Total students = 300

Therefore, the total number of students is 300.

To find the number of students who failed, we multiply the total number of students by the percentage who failed:

Number of students who failed = 300 * 40% = 120

Hence, option A, 120, is the correct answer.
