In logical mathematics there are two examples I present first Roses are flowerssecond Red roses are flowers what do you cll the first and second statement

the first is "all statement" and the second is " existential statement"

How do you find the equation of a graph

You find the equation of a graph by finding an equation with a graph.

What is the scientific notation of 64000000

6.4*107

Rewrite the formula to solve for c

c=a-b

True or False You can rely solely upon induction to prove that your conclusion is correct

False

2a - 8 10 or 8a 4 68

all real numbers :)

Mimi had 174 to buy tickets to a concert The adult tickets cost 10.50 and the student tickets cost 7.50 She bought 4 more student tickets than adult tickets How many student tickets did she buy

12 student tickets

What is the Process that scientists use to solve a problem

Scientific method.

A ship is traveling at an average velocity of 28 miles per hour How far will the ship travel in two days

1344

Which has a greater kinetic energy a car traveling at 30 km h or a car half that mass traveling at 60 km h

60. K= 1/2mv^2 therefore when v is larger, there is more kinetic energy

A conveyor belt carries filled bottles of milk to be packed The bottles are placed five feet apart on the belt If the belt is moving at a rate of two feet per second how many bottles will be packed

24 bottles

A plane flew nonstop from Dallas to Las Vegas The distance was 1350 miles and the plane averaged 300 miles per hour How long was the plane in the air

4.5 hours

7x-4x plus 2x plus 5 equals 2x plus 14

7x-4x+2x+5=2x+14

5x+5=2x+14

3x=9

x=3

A Mississippi cub-pilot summary

For a good summary read the book so you can understand it. BTW: it is not that long!! Don't be lazy.

3a plus 5 equals 5a plus 3

If 3a+5=5a+3, then:

3a+5 - 3a = 5a+3 - 3a

5=2a+3

5 - 3=2a+3 - 3

2=2a

a=1

Can an object have no either potential energy and kinetic energy

Yes. If it is at whatever you define to be zero level for the purposes of calculating potential energy (often this will be ground level), and doesn't move, then it has zero (gravitational) potential energy, and zero kinetic energy.

What does the captain do when he learns that Twain attacked Brown

He tells Twain to attack Brown again when they are on shore.

How do you get the answer 7 using only numbers -4-3-2-1

[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7

[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7

[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7

[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7

What can you determine when you use deduction and start and start from a given set of rules and conditions

What must be true

True or false if you took a true if then statement inserted a not in each clase and reversed the clauses the new staement would also be true

True. In that case, each of the statements is said to be the contrapositive of the other.

In geometry you can use deductive rules

In geometry, deductive rules can be used to prove conjectures.

When the absolute value of the slope gets smaller the graph of a line gets what

When the slope of a line reaches zero it then will be parallel to the x or y axes depending if its a positive or a negative slope.
