A school has 400 students. They all come to school by bus, and each bus carries the same number of students. How many students might there be on each bus?

I put some counters into groups with the same number in each group. I can’t remember what I did, but I do remember that I had 12 counters. What might the groups have been?

Answers

Answer:

23 times 8 then divide the answer by two

(i looked it up and the answers are the same.)

Question 1 A. Do 23 times 2 times 2. This will give you the same answer as if you were to use 4.

Question 1 B. Use 10 times 2 plus the number in the ones place, then multiply  them together.

Question 2. There would be an average of 40 student per bus, therefore, there will be 10 buses, and 40 students in each bus.

Question 3. You could put 12 counters in: 6 groups of 2, 2 groups of 6, 4 groups of 3, or 3 groups of 4. (I think there's more but that's all I can think of. Hope you got the memo)

explain: 1 pound is 16 ounces 3x16 is 48 we only have 3.5 pounds. add half of 16 in 48 and we get 56 which is over the amount that we have of rice so it is false because we do not have enough pounds of rice. hope this helps :)

Which of the following functions represents the values in the table below?

x     0         2         4         6    
f(x)     2         10         66         218    

f(x) = -3x - 2x^2

f(x) = x^2/2

f(x) = 2 + x^3

f(x) = 3x - 2

Answers

As you can see, in the table of the first function, f(2) = 18, and in the table of the second function g(2) = 18. Then, for x = 2, f(x) = g(x). and x =2 is the solution of the equation.

Answer: x = 2.

The required function that represents the value in the table is f(x) = 2 + x³. Option C is correct.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Put x = 0 in every given function,
Then that function that gives 2 will be our required function,
So,

f(x) = 2 + x³.
f(0) = 2 + 0³
f(0) = 2

Thus, the required function that represents the value in the table is f(x) = 2 + x³. Option C is correct.

On the graph, two right triangles have the line as the hypotenuse. In this task, you will use these triangles to show that the slope between points E and A is the same as the slope between points A and C.


Q1:
Which angles of the triangles measure 90°?

Q2: To show that the other two angle measurements in each triangle are equal, you can use parallel lines cut by a transversal. Which two pairs of line segments formed by triangle sides are parallel, and what is the transversal for each pair?

Answers

Answer:

1.The 6th one

2. The pairs can be (6, 8)

Step-by-step explanation:

We know that, the Slope is always given as [tex]\bold{\dfrac{Rise}{Run}}[/tex], where the rise is the vertical height of the slope and run is the horizontal length of the slope.

For Δ ADE,

rise = DE = 4 units,

run = DA = 6 units,

[tex]\bold{slope = \dfrac{Rise}{Run} =\dfrac{4}{6} = \dfrac{2}{3}}[/tex]

For Δ ABC,

rise = AB = 2 units,

run = BC = 3 units,

[tex]\bold{slope = \dfrac{Rise}{Run} = \dfrac{2}{3}}[/tex],

Thus, the slope of line EA and AC is equal.

We know in a Right Angle Triangle the side opposite to the right angle is the longest side and it is known as hypotenuse.

As already mentioned in the question " two right triangles have the line as the hypotenuse", which means line EA and line AC are already said as the hypotenuse of the triangles. therefore, the angle opposite to them is the right angle in the triangles.

1.)  

In ΔABC, the hypotenuse is the line AC, therefore, the right angle is the opposite angle which is ∠ABC.

Similarly,  In ΔEDA, the hypotenuse is the line EA, therefore, the right angle is the opposite angle which is ∠EDA.

2.)

Parallel lines are those lines that always maintain the same distance between them and will never meet. whereas, a transversal is a line that crosses two or more parallel lines. As shown in the image below,

Here, there are two pairs of parallel lines cut by a transversal

Pair I:   line ED and line AB are a pair of parallel lines, can be easily seen if both the lines are extended, while AD (or x-axis), line BC(only if extended), and line EC are the transverses between them.

Pair II:  line DA and line BC are a pair of parallel lines, can be easily seen if both the lines are extended, while AB (or y-axis), line ED(only if extended), and line EC are the transverses between them.
