### Is 500 seconds graeter than less than or equal to 5 minutes

Each minute has 60 seconds, so to find how many minutes 500 seconds are:
1.) Divide 500 by 60
500 ÷ 60 = 8.3
Therefore, 500 seconds is equal to 8.3 minutes.
2.) Compare
5 minutes < 8.3 minutes
8.3 minutes is greater than 5 minutes.

### Explain why a square can never be a trapezoid

A square can never be a trapezoid because a trapezoid doesn't have all equal sides and vertices while a square has 4 sides of the same length and four angles of the same length. Also, a trapezoid has no set of parallel lines while a square has two sets of parallel lines.

### A school principal ordered 1000 pencils he gave an equal number to each of seven teachers until he had given out as many as possible how many pencils were left

If you have 1000 pencils and you divide by 7 teachers, you would have 142 pencils divided evenly. Then you would take the 142 pencils and multiply by 7 which will give you a total of 994 pencils that went to the teachers in total. So the remaining pencils would be 1000 minus 994 and the total left over will be 6 pencils. I hope this helps.

O = 50°

### Explanation and solution;

• An isosceles trapezoid is a quadrilateral that has a pair of sides that opposite and are parallel and another pair of sides that are opposite and are congruent.
• Both pairs of opposite angles in an isosceles trapezoid are supplementary which means their sum add up to 180°.

Therefore;

∠ B  + ∠ A = 180° and ∠T + ∠O = 180°

Hence; ∠O = 180 -∠T

= 180 - 130°

= 50 °

Explain why the initial value problem y prime equals the product of 4 times x and the square root of the quantity 1 minus y squared with y(0) = 4 does not have a solution.

Step-by-step explanation:

Given is a differential equation as:

We can solve this by separation of variables method

To find C:

Given y(0) =4

Substitute x=0 and y =4

sin inverse of 4 = C

But sin inverse is valid only for values between -1 and 1

Hence C is not a real value

No solution for this.

### 4. Ten outcomes are all equally likely from an event and you choose one of them at random. What is the probability that the outcome you chose will be the outcome of the event? 0.50 0.10 0 0.90

Answer:  The correct option is (B) 0.10.

Step-by-step explanation:  Given that ten outcomes are all equally likely from an event and we choose one of them at random.

We are to find the probability that the outcome we chose will be the outcome of the event.

Since the outcomes are equally likely, so

let A denotes the event that any one of the outcome is chosen and S be the sample space for the experiment.

Then, n(A) = 1 and n(S) = 10.

Therefore, the probability  that the outcome we chose will be the outcome of the event is given by

Thus, teh required probability is 0.10.

Option (B) is CORRECT.

### Indicate the equation of the given line in standard form. Show all of your work for full credit. The line containing the median of the trapezoid whose vertices are R(-1, 5) , S(1, 8), T(7, -2), and U(2, 0).

The required equation is .

Step-by-step explanation:

The median of a trapezoid is a segment that joins the midpoints of the nonparallel sides.

It is given that the vertices of trapezoid are R(-1, 5) , S(1, 8), T(7, -2), and U(2, 0).

From the below figure it is clear that the side RS and TU are non parallel sides.

The midpoint of RS is

The midpoint of TU is

It means the line containing the median of the trapezoid is passes through the points

If a line passes through two points the equation of line is

Multiply both the sides by 6.

Add 10x on both the sides.

Add 39 on both the side.

Therefore the required equation is .

This is the concept of quadratic equations, to find out whether the two expressions we need to expand each of them:
(x)=(25+10x)(300-36x)
(x)=25(300-36x)+10x(300-36x)
(x)=7500-900x+3000x-360x^2
(x)=7500+2100x-360x^2

(x)=(100+20x)(100-12x)
(x)=100(100-12x)+20x(100-12x)
