The Number of sodas sold: 174,
The number of hot dogs sold: 58.
What is a linear equation?Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.
Both linear equations with one variable and those with two variables exist.
Given a vendor sold a combined total of 232 sodas and hot dogs.
let S for the number of sodas sold and H for the number of hot dogs sold,
S + H = 232
The number of sodas sold was three times the number of hot dogs sold
S = 3H
substitute the values,
S + H = 232
3H + H = 232
4H = 232
H = 232/4
H = 58
and the number of sodas sold
S = 3H
S = 3*58
S = 174
Hence the number of sodas sold = 174,
and the number of hot dogs sold = 58.

a boat is traveling east across a river that is 112 meters wide at 8 meters per second. If the river has a northeast current of 5 meters per second, what is the resultant speed of the motorboat rounded to the nearest tenth?
Resultant speed of the motorboat is 9.4 m/s.
What is Pythagorean Theorem?Pythagorean theorem states that the squared value of longest side in an right angle triangle will be equal to the addition of the squared value of two smaller sides. Thus, the resultant speed of the boat is 9.4 m/s
This is the concept of application of the pythagorean theorem.
The boat is traveling in the east direction at a speed of 8 m/s but the river has a northward current of 5 m/s. We know than both the directions (East and North) are perpendicular to each other. The bend tending toward east but the river slows down the speed and makes the boat tending toward north-east.
Thus, by applying Pythagorean theorem, the resultant speed can be calculated as:
c² = a² + b²
c² = 8² + 5²
c² = 64 + 25
c² = 89
c = [tex]\sqrt{89}[/tex]
c = 9.4 m/s
Hence, the resultant speed of boat is 9.4 m/s.

A line has a slope of – 9 and includes the points ( – 9,1) and ( – 10,q). What is the value of q?
To find the value of q, we can use the point-slope form of a line:
y - y1 = m(x - x1)
where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) is a second point on the line.
In this case, we have the slope of the line as -9 and the point ( -9, 1), so we can plug in the values:
y - 1 = -9 (x - (-9))
Expanding and solving for y, we get:
y = -9x + 90
Next, we want to find the value of y when x = -10. Substituting this value into the equation:
q = -9(-10) + 90
Solving for q:
q = -90 + 90 = 0
So, the value of q is 0.
justin had 3 rolls of ribbon. he used 1/5 of a roll of ribbon to tie a parcel and 2/5 of another roll of ribbon to tie a present. how many rolls of ribbon did he use in all?
Justin used average two rolls of ribbon in total, using 1/5 of one and 2/5 of another.
Justin had 3 rolls of ribbon before he started tying parcels and presents. He used 1/5 of a roll of ribbon to tie a parcel, and then used 2/5 of another roll of ribbon to tie a present. This means that he used two rolls of ribbon in total, with 1/5 of one and 2/5 of the other. He still has one roll of ribbon remaining, meaning that he didn't use all three rolls of ribbon. To calculate the total amount used, you would need to multiply 1/5 and 2/5 by the length of the ribbon, or alternatively multiply the two fractions together to get 2/5 of a roll of ribbon used. This means that he used two rolls of ribbon in total, with 1/5 of one and 2/5 of the other.

B.) What are the x-intercepts/roots/zeros? Show your work. (4 points)
C.) Describe the end behavior of this function (2 points)
D.) Draw a graph of this function, carefully labeling your intercepts and showing the end behavior.
A. The y-intercept is at the point (0, 0).
B. The zeros are x = 0 or x = ±√5
C.
How to solve the expressionA) The y-intercept of this graph is the point where x = 0.
When x = 0, the value of y
= 0^4 - 5*0^2
= 0.
Therefore, the y-intercept is at the point (0, 0).
B) The x-intercepts/roots of the function are the values of x that make y = 0.
To find these values, we need to set y = 0 and solve for x:
x⁴ - 5x² = 0
x⁴ = 5x²
x² = x⁴/5
x = ±√(x⁴/5)
We can simplify this expression by factoring x² out of both sides:
x²(x² - 5) = 0
x² = 0 or x² - 5 = 0
x = 0 or x = ±√5
hence the x-intercepts are at x = 0 and x = ±√5.
C) The end behavior of this function refers to how the graph of the function approaches the x-axis as x approaches positive infinity and negative infinity.
x → ∞ f(x) → ∞
x → -∞ f(x) → -∞

jennifer has three more dimes than nickels and three times as many quarters as nickels. if she has $7.50, how many quarters does she have? www.wyzant
Jennifer has 48 nickels, which means she has 144 quarters.
Let's call the number of nickels Jennifer has "n".
Since Jennifer has three more dimes than nickels, she has n + 3 dimes.
And since she has three times as many quarters as nickels, she has 3n quarters.
We can start by figuring out the total value of the nickels and dimes in terms of cents:
n * 5 cents + (n + 3) * 10 cents = 750 cents
Expanding the right side of the equation and solving for n:
5n + 10n + 30 cents = 750 cents
15n + 30 cents = 750 cents
15n = 720 cents
n = 48
So Jennifer has 48 nickels, which means she has 3 * 48 = 144 quarters.

a sample of 4 different calculators is randomly selected from a group containing 47 that are defective and 29 that have no defects. what is the probability that all four of the calculators selected are defective? round to four decimal places.
The probability of selecting 4 defective calculators is 0.0009.
The probability of selecting 4 defective calculators out of a group containing 47 defective and 29 non-defective calculators can be calculated using the formula for a combination. The formula is n!/r!(n-r)! where n is the total number of items and r is the number of items being selected. In this case, n is 76 (47 defective + 29 non-defective) and r is 4. Therefore, the probability of selecting 4 defective calculators is 0.0009. To round this answer to four decimal places, the answer is 0.0009.
To calculate this answer, the first step is to calculate the total number of combinations that can be made using 4 items out of 76 items. This is calculated using the formula n!/r!(n-r)!. The numerator, n!, is equal to 76! which is equal to 5.43e+102. The denominator, r!(n-r)!, is equal to 4!(76-4)! which is equal to 5.90e+09. By dividing the numerator by the denominator, the probability of selecting 4 defective calculators is 0.0009. To round this answer to four decimal places, the answer is 0.0009.

concert held near the radio station.
Is this sample likely to be representative of the population? Explain.
Answer:
No, this sample is not likely to be representative of the population.

The Fréchet distance is a mathematical metric for comparing the similarity of curves that takes into account the position and arrangement of curve points. Maurice Fréchet is honored by having his name used. The pairs of points that make up the Fréchet distance sweep continuously along their respective curves, so the Fréchet metric takes the flow of the two curves into account. As a result, the Hausdorff distance and other similarity measures for arbitrary point sets are inferior to the Fréchet distance for curves. Two curves might have a small Hausdorff distance but a large Fréchet distance.
