Question
What is 644 divide by 8 times 8.
Solution 1
644 divided by (8 x 8) (8x8) equals 61 so 644 divided 61 equals 10.557377049
Solution 2
The answer would be 644 because you divided 8 which would equal 80.5 and then you multiply that by 8 you get 644.
Question
A ________________ event has a 100% chance of occurring. Example: Picking a red ball from a bag of only red balls.
Solution 1

We have been given that probability of the even is 100%. In other words we can say that the probability is 1. It means that the event will certainly occur.

Now, we know that the highest value of probability is 1 and lower value is 0.

Mathematically, we can represents it as

If the probability is 0 then the event will never occur.

And if the probability is 1 then event will definitely occur.

Therefore, A certain event has a 100% chance of occurring.

**MARKING BRAINLIEST IF RIGHT AND IF YOU SHOW WORK** 3. Use the Fermi process to estimate the number of bricks needed to fill an empty bathtub. Show your work. My teacher said you can use approximate dimensions of the bricks and bathtub. He said use the easiest ones so that it will be easy to solve.
Solution 1
Bath tub: 60 x 30 x 18

brick: 8 x 4 x 2

fermi process:
(60 x 30 x 18) /  (8 x 4x 2)

=  32,400 / 64

= 506.25

estimated as 500 bricks

Question
Which statement follows from the given theorem? Theorem: The diagonal of a parallelogram divides it into two congruent triangles. A. Diagonals of a parallelogram bisect opposite angles. B. Consecutive sides of a parallelogram are congruent. C. Consecutive angles of a parallelogram are congruent. D. Consecutive angles of a parallelogram are supplementary.
Solution 1

Theorem : The diagonal of a parallelogram divides it into two congruent triangles.

Properties of parallelogram

1. Opposite sides are equal and parallel.

2. Diagonal bisect each other.

3. Opposite Angles are equal.

If you will look at the first three options

A:  Diagonals of a parallelogram bisect opposite angles.→→False(Alternate angles are equal)

B: Consecutive sides of a parallelogram are congruent.→→→False(Opposite sides are congruent)

C: Consecutive angles of a parallelogram are congruent.→→→False(Opposite angles are congruent)

D: Consecutive angles of a parallelogram are supplementary.→→→→True

For,any parallelogram, having vertices , A, B and C and D

Opposite sides are parallel, so

1.∠A + ∠B=180°

2.∠C + ∠B=180°

3.∠C+ ∠D=180°

4. ∠A + ∠D=180°

Option D

Solution 2

Opposite sides of a parallelogram are congruent.

Question
The path of a rocket ship is given by the parametric equations x(t)=3t and y(t)=4t^2+1, where t is the time in seconds after launch. Where is the ship after 10 seconds? A.) (3,4) B.) (3,5) C.) (30,401) D.) (30,501)
Solution 1
X(t)=3t
y(t)=4t^2+1

Time (seconds):

Where is the ship after 10 seconds?
t=10→Position: Point: P=(x(t), y(t))=(x(10), y(10))=?

t=10→x(10)=3(10)→x(10)=30
t=10→y(10)=4(10)^2+1=4(100)+1=400+1→y(10)=401

Position: P=(x(10), y(10))=(30, 401)

Question

Solution 1

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The expression that is not the same as the rest of the expressions is

8 - ab.

### What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3x - 5 is an expression.

4x + 4 is an expression.

4 x 5 - 5x is an expression.

We have,

1) -8ab

2) -8 (a) (b)

= -8ab

3) 8 - ab

4) -8.a.b

= -8ab

We see that,

All the expressions are the same except the expression

8 - ab

Thus,

The expression that is not same with the rest of the expression is

8 - ab.
