Ms. Terry's class is hosting a fundraisingchallenge. The students in her class are
divided into 4 teams. Each team has an
equal number of students. Do you have
enough information to find how many
students are on each team? Explain.

Answers

Answer 1

Answer:

In being able to find out whether it is possible to know the number of students on each team, there simply isn't enough information to do so.

In order to find out the number of students on each team, the following formula is necessary:

= Number of students in general / Number of teams

The number of teams is 4 so the denominator is present.

We however, do not have the number of students in general so we are unable to find out the number of students in each team.

In conclusion, we do not have enough information to find out the number of students in each team.

Answer 2

Answer: You do not have enough information because you need to know how many students are in the class to be able to divide them into 4 equal groups we do know that it has to be a positive integer that can be evenly divided by 4

The length of each side of a cube is increased by a factor of 4. What is the effect on the volume of the cube?

Answers

Answer:

When dealing with VOLUME, an increase in a linear quantity, produces a third power result in the volume.

Increase the sides of a cube by 2 produces an 8 times effect in the volume.

Increasing each side of a cube by 4 produces a chnage of 4 * 4 * 4 or

64 times in the volume.

If 9x+2y^2−3z^2=132 and 9y−2y^2+3z^2=867, then x+y =

Answers

Answer:

$x + y = (1000)/(9)$

Step-by-step explanation:

Step 1: Identify the approach:

With this problem, the general solution is to try manipulate given data and transform data into a new form, in which, the desired value $(x + y)$ is on the left side and all of other components which do not contain $x$ or $y$ are on the right side.

Step 2: Analyze:

$9x + 2y^(2) - 3z^(2) = 132\n9y - 2y^(2) + 3z^(2) = 867$

Realize that in both equations, the $2y^(2)$ and $3z^(2)$ are in form of different signs. Then adding up corresponding sides of both equation can help eliminate these undesired components.

Step 3: Perform manipulation:

$9x + 2y^(2) - 3z^(2) + 9y - 2y^(2) - 3z^(2) = 132 + 867$

Rearrange:

$(9x + 9y) + (2y^(2) - 2y^(2)) +(3z^(2) - 3z^(2)) = 132 + 867$

Simplify:

$9(x + y) + 0 + 0 = 1000$

Simplify:

$x + y = (1000)/(9)$

a jeepney ride in the sinakos 9 pesos for the first 4 kilometers and each additional km at 0.75 pesos to the fair use a piecewise function to represent the jeepney fare in terms of the distance in kilometers

Answers

Answer: f(x) = 9 pesos if 0km ≤ x ≤ 4km

f(x) = 9 pesos + (x - 4km)*0.75 pesos if 4km ≤ x

Step-by-step explanation:

Ok, we know that:

For the first 4km, we have a fixed price of 9 pesos.

For any km after the 4km mark, we have an extra of 0.75 pesos.

Then if x is the number of kilometers, we can write this as:

f(x) = 9 pesos if 0km ≤ x ≤ 4km

f(x) = 9 pesos + (x - 4km)*0.75 pesos if 4km ≤ x

Where we use (x - 4km) because we start counting after the 4km mark.

Final answer:

The student correctly solved the equations given for x. Note that an equation with an unknown variable squared might have two solutions. The way to solve for x alters according to what the equation requires, whether it is adding, subtracting, or dividing.

Explanation:

It seems like the student is trying to solve equations for x. The equations given were all solved correctly. Keep in mind that when an equation contains an unknown variable squared, there could be two solutions, and one or both could be reasonable depending on the problem. For example, consider the equation x² +0.0211x -0.0211 = 0. This could be rearranged to solve for x. Other variables are known unless additional calculations needed if they are not.

Remember that the principle of altering the equation to solve for x is employed, whether we add, subtract or divide by certain values. Like mentioned in the information provided, when dividing by powers of 10, you would move the decimal to the left, corresponding to the number of zeros in the power of ten.
