What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
Let the first number would be x and the second number would be y
We have been given that the two numbers with a product of 30,
So, x × y = 30
x = 1/y .....(i)
And the sum of 17, then x + y = 17 .....(ii)
Take both equations, then solves them and we get the values that are:
x = 15 and y = 2
So, 15 × 2 = 30 and 15 + 2 = 17
Thus, the required numbers are "15" and "2".

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.

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.

Five cans of tomatoes cost $6.50. At this rate, how much will nine cans of tomatoes cost?
The cost of one can of tomatoes is $1.30, so nine cans at this rate would cost $11.70.
If five cans of tomatoes cost $6.50, to find the cost of nine cans, we first need to find the cost of one can of tomatoes. We do this by dividing the total cost by the number of cans.
Cost per can = Total cost / Number of cans
Cost per can = $6.50 / 5
Cost per can = $1.30
Now that we know how much one can costs, we can find out how much nine cans will cost by multiplying the cost per can by nine.
Total cost for nine cans = Cost per can × Number of cans
Total cost for nine cans = $1.30 × 9
Total cost for nine cans = $11.70
Therefore, nine cans of tomatoes will cost $11.70.
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

Evaluate ƒ(x) = 3x + 8 for x = 1.
Answer: The required value of f(x) for x = 1 is 11.
Step-by-step explanation: We are given to evaluate f(x) for x = 1, where
[tex]f(x)=3x+8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To evaluate the required value, we need to substitute x = 1 in expression (i).
So, putting x = 1 in (i), we get
[tex]f(1)=3\times1+8=3+8=11.[/tex]
Thus, the required value of f(x) for x = 1 is 11.
There is a box full of toys. There are four Lego sets, six video games, and five remote control cars. You randomly choose a toy. Find the probability of choosing a remote control car. A. 1/7 B. 7/24 C. 1/3 D. 11/24
The probability of choosing a remote control car from the box is 1/3, which is calculated by dividing the number of remote control cars (5) by the total number of toys (15).
Explanation:To find the probability of choosing a control car from the box, we use the formula for probability, which is:
Probability = Number of favorable outcomes / Total number of possible outcomes
The number of favorable outcomes is the quantity of remote control cars which is 5. The total number of toys is the sum of all the toys, which are 4 Lego sets + 6 video games + 5 remote control cars = 15 toys in total.
The probability is therefore calculated as:
Probability of choosing a remote control car = 5 (number of remote control cars) / 15 (total number of toys) = 1/3
Hence, the correct answer is C. 1/3.

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.
