Mika would need 10 minutes to eat 35 hot dogs.
Mika can eat 21 hot dogs in 6 minutes. So Mika eats 21 hot dogs/6 minutes
So Mika eats 35 hot dogs/m minutes. The proportion is set up like this:
21/6 = 35/m Then, cross-multiply:
6·35 = 21m
m = 210/21
m = 10 minutes

motorcycle cover 210 kilometre distance with 5 l of petrol how many kilometre does it cover with 8 litre of petrol? how much petrol is needed to cover 588 kilometre
Answers
Answer:
A: 336 km
B: 14 L
Step-by-step explanation:
Use a proportion
210 km / 5 L = x / 8L Cross multiply
8*210 = 5 x
1680 = 5x
x = 1680 / 5
x = 336 km
===============
210 /5 = 588/x Cross multiply
210x = 588 * 5
210x = 2940 Divide by 210
x = 2940/210
x = 14 L

two buses leave the terminal at 12 noon. bus #86 takes 45 minutes to complete its route. bus #79 takes 60 minutes when is the next time the two buses will arrive together at the terminal
Answers
Answer:
3 hours from noon, or 3 pm.
Step-by-step explanation:
As of 12 noon, the frequencies are 45 and 60 minutes.
To find out when they leave at the same time again, we need the LCM (least common multiple) of the two frequencies, i.e.
LCM (45, 60) = common time from {45,90,135,180,225,270,315,360....} and{60,120,180,240,300,360,...}
We see that they leave at the same time again at 180 and 360, ... minutes. Since 180 minutes is the least common multiple, 180 is the next time they leave together again, or 3 hours after noon, i.e. 3pm.

Describe the process of graphing a quadratic equation without using graphing technology. How many solutions can a quadratic equation have and why does it vary? How would the corresponding graphs look like?
Answers
Find the x and y-intercepts of the equation. Then calculate the points at constant intervals and plot and connect those points on a makeshift graph. A quadratic equation can have 2 solutions, 1 solution, or none. The corresponding graphs(if two solutions) would most probably cross over the x-axis twice.

I'm putting all my savings into stocks because stocks always outperform other types of investments over the long term
Answers
Incomplete question. The full question read;
Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning.
I'm putting all my savings into stocks because stocks always outperform other types of investments over the long term.
Choose the correct answer below.
A. The statement does make sense because stocks historically outperform bonds and cash over the long term and investing in stocks is high-risk, which offers higher returns.
B. The statement does not make sense because although stocks historically outperform bonds and cash over the long term, investing in stocks is high-risk and there is no guarantee that the investment will yield a high return.
C. The statement does make sense because stocks are a low-risk investment, offering predictable low returns.
D. The statement does not make sense because stocks never outperform bonds and cash over the long term.
Answer:
B. The statement does not make sense because although stocks historically outperform bonds and cash over the long term, investing in stocks is high-risk and there is no guarantee that the investment will yield a high return.
Step-by-step explanation:
Of course, the statement does not make sense because it does clearly say the reality about stocks. By saying "stocks always outperform" other investment types it hides the possibility of losses from stock investments.
For example, a company's stock may be negatively affected as a result of employee layoffs or unexpected company scandals. Hence, there is no guarantee that the investment will yield a high return.
The two lines graphed on the coordinate grid each represent an equation. Which ordered pair represents a solution?
Answers
Answer:
The ordered pair (-3, 3) represents the solution of two lines on the coordinate grid.
Thus, option B is true.
Step-by-step explanation:
As we know that the point of intersection of two lines is the solution of the lines.
Given the graph of the lines, we can see that the two lines intersect at the point (-3, 3).
i.e. at x= -3, y = 3
The point of intersection is (-3, 3)
Thus, the ordered pair (-3, 3) represents the solution of two lines on the coordinate grid.
Thus, option B is true.

B

A matrix contains 48 elements. Which of the following cannot equal the number of rows of the matrix?

Answers
A. 18
A matrix is a rectangular array of numbers arranged in rows and columns. The array of numbers below is an example of a matrix. The number of rows and columns that a matrix has is called its dimension or its order. By convention, rows are listed first; and columns, second.Here the matrix contains 48 elements and the factors of 48 are
48×1,1×48
24×2,2×24
12×4,4×12
6×8,8×6
3×16,16×3
So, 18 is not the factor of 48.
16, 8, and 24 can go into 48 but not 18.
Therefore option A is correct.

Answers
If we write the quadratic equation in the vertex form, will be easy to find the vertex.
The vertex form of a quadratic function is:
y = a(x - h)² + kWhere the vertex is (h. k).
We have:
y=(x+2)(x-2)
y = x² - 4Form this we conclude: a = 1, h = 0, k = -4. Then:
A/ The vertex of y is (0, -4)
The vertex will be the y value when x is 0, since 0 is the average number of the roots of this quadratic.
Then, you get (0+2)(0-2)=2*-2=-4
