What's the principal square root of 169
The principal square root of 169 is 13.
The principal square root of a number is the non-negative square root.
The principal square root of 169 is the non-negative number that, when multiplied by itself, equals 169.
We are looking for a number such that when it is squared (multiplied by itself), it equals 169.
This can be expressed mathematically as:
x² = 169
The solution to this equation is
x = √169.
169 is a perfect square, and its square root is 13 because:
13 × 13 = 169.
Therefore, the principal square root of 169 is 13.

An air show is scheduled for an airport located on a coordinate system measured in miles. The air traffic controllers have closed the airspace, modeled by a quadratic equation, to non-air show traffic. The boundary of the closed airspace starts at the vertex at (10, 6) and passes through the point (12, 7). A commuter jet has filed a flight plan that takes it along a linear path from (–18, 14) to (16, –13). Which system of equations can be used to determine whether the commuter jet’s flight path intersects the closed airspace?

How many ounces of gold are in anan 18-karat gold chain that weighs 2.7 ounces?
A karat is a measure of the amount of gold in the gold chain. The karat has a maximum value of 24 karats. This means that an 18 karat of gold chain contains 18 parts of pure gold for every 24 parts of gold chain. Therefore:
gold = (18 / 24) * 2.7 ounces
gold = 2.025 ounces
You ride your bike to school. As you approach an intersection, you decrease your speed by 1.5 miles per hour per second. Select an inequality that represents the time tt (in seconds) until your speed decreases by more than 10.5 miles per hour. Then solve the inequality.
Answer:
The time elapsed is greater than 7 seconds
Step-by-step explanation:
From definition
acceleration = change in speed/time elapsed
or:
a = Δv/t
Rearranging:
a*t = Δv
If your speed decreases by more than 10.5 miles per hour, then:
Δv > 10.5
Replacing with the previous equation and solving for t:
a*t > 10.5
t > 10.5/1.5
t > 7 s

How do you write a piecewise function
To write a piecewise function, you need to define different equations for different intervals of the independent variable.
Explanation:To write a piecewise function, you need to define different equations for different intervals of the independent variable. Each equation represents a different part or piece of the function. Here's an example:
f(x) =
2x + 1, if x ≤ 0x^2, if 0 < x ≤ 54 - x, if x > 5In this function, the equation 2x + 1 is used for values of x that are less than or equal to 0, the equation x^2 is used for values of x between 0 and 5 (inclusive), and the equation 4 - x is used for values of x greater than 5.

A balloon is released on top of a building. The graph shows the height of the balloon over time. What does the slope and y-intercept reveal about the situation?
Answer:
C. The balloon starts at a height of 500 ft and rises at a rate of 150 ft.
Step-by-step explanation:
We have been given a graph which represents the height of the balloon over time.
We can see from our graph that y-intercept, which represents the height of the balloon (in thousand feet) at time equals zero, is 0.5. To find the correct y-intercept we will multiply 0.5 by 1000 as height of the balloon is given in thousand feet.
[tex]\text{y-intercept}=(0.5\times 1000)\text{ feet}=500\text{ feet}[/tex]
Therefore, y-intercept represents that the balloon starts at a height of 500 feet.
Now let us find slope of our given line using slope formula.
[tex]\text{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]y_2-y_1[/tex] is vertical change or rise.
[tex]x_2-x_1[/tex] is horizontal change or run.
Upon substituting given values in above formula we will get,
[tex]\text{Slope}=\frac{3.5-0.5}{20-0}[/tex]
[tex]\text{Slope}=\frac{3}{20}[/tex]
[tex]\text{Slope}=0.15[/tex]
Now let us multiply 0.15 by 1000 as height of balloon is given in thousand feet.
[tex]\text{Slope}=0.15\times 1000=150[/tex]
Therefore, slope of our line is 150 which means that height of balloon is increasing 150 feet per second or balloon is rising at a rate of 150 feet per second.
Upon looking at our given options we can see that option C is the correct choice.

If EF =9x+17 , FG = 35 , and EG=196 , find the value of x
The required simplified value fo x is 16 in the expression of the line segment.
Given that,
If EF =9x+17 , FG = 35 , and EG=196 , find the value of x is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here
EG = 196
EF + FG = 196
9x + 17 + 35 = 196
9x + 52 = 196
9x = 196 - 52
9x = 144
x = 144/ 9
x = 16
Thus, the required simplified value fo x is 16 in the expression of the line segment.

A gumball machine has just been filled with 50 black, 150 white, 100 red, and 100 yellow gumballs that have been thoroughly mixed. sue and jim each purchase one gumball. what is the likelihood that both sue and jim will get red gumballs?
Final answer:
To calculate the likelihood of both Sue and Jim getting red gumballs, we multiply the probability of each event occurring sequentially. After Sue gets a red gumball, the chances are 1/4, and then 99/399 for Jim. The final probability of both getting red gumballs is 99/1596 or about 6.203%.
Explanation:
The likelihood that both Sue and Jim will get red gumballs from the gumball machine can be calculated using basic probability principles. First, we need to determine the total number of gumballs in the machine. This is the sum of black, white, red, and yellow gumballs, which are 50, 150, 100, and 100 respectively, making a total of 400 gumballs.
The probability that Sue gets a red gumball is the number of red gumballs divided by the total number of gumballs in the machine, which is 100/400, simplifying to 1/4. When Sue takes a gumball, assuming she gets a red one, there are now 399 gumballs left with 99 being red. Therefore, the probability that Jim also gets a red gumball is 99/399. To find the likelihood of both events occurring, we multiply these probabilities:
P(Both Sue and Jim get red gumballs) = P(Sue gets a red gumball) × P(Jim gets a red gumball after Sue) = (1/4) × (99/399).
Now we simplify and multiply these fractions to get the final probability. After simplifying, the final probability is 99/1596, which is approximately 0.06203 or 6.203% chance that both Sue and Jim will get red gumballs.

mrs perry shares out 30 biscuits between gemma and zak in the ration 1:4 how many biscuits does each child get
Gemma gets 6 biscuits, and Zak gets 24 biscuits when Mrs. Perry shares out 30 biscuits between them in the ratio 1:4.
To solve this problem, we need to divide the 30 biscuits according to the ratio 1:4 between Gemma and Zak.
Calculate the total parts in the ratio.
Total parts = 1 (from Gemma) + 4 (from Zak) = 5 parts
Find out how many parts each child gets.
For Gemma:
Gemma's share = (1 part ÷ 5 parts) × 30 biscuits
= (1/5) × 30
= 6 biscuits
For Zak:
Zak's share = (4 parts ÷ 5 parts) × 30 biscuits
= (4/5) × 30
= 24 biscuits
Verify the result.
Gemma gets 6 biscuits, and Zak gets 24 biscuits.
6 + 24 = 30 biscuits (which is the total), so the division is correct.
Thus, Gemma gets 6 biscuits, and Zak gets 24 biscuits when Mrs. Perry shares out 30 biscuits between them in the ratio 1:4.
