Answer:

2/3

Step-by-step explanation:

Between the two points, the line goes up 4 points and to the right 6 points. The slope is rise over run, so in this case the rise is 4 and the run is 6

This makes our slope:

4/6 which simplifies to 2/3

Answer:

3/14 of a liter of salt

Step-by-step explanation:

Step one:

given

tot amount of salt= 5/7 of a liter of salt

that is 1*5/7= 5/7 liters

She used 1/2 of a liter for an experiment

Required:

the remaining amount of salt

Step two:

we are going to subtract the salt used for the experiment from the total

= 5/7-1/2

= 10-7/14

= 3/14

The remainder is 3/14 of a liter of salt

By Using -:

BODMAS rule

18-{3+(6-7)}

According to bodmas rule

18-{3+(6-7)}

→ 18 - { 3 - 1 }

You answer is going to be: 540

The one digit number is 4 and three digit number is 727.

Let us consider the one digit number be a and three digit number be b. Given that their sum is equal to 731.

a + b = 731 : equation 1

Also, their product is equal to 2908.

a × b = 2908 : equation 2

Now, from equation 1, the value of b is

b = 731 - a : equation 3

Putting the value of b in equation 2, we get

a (731 - a) = 2908

731a - a² = 2908

a² - 731a + 2908 = a

Using middle term splitting, the equation can be written as

a² - 727a - 4a + 2908 = 0

a(a - 727) - 4(a - 727) = 0

a - 4 = 0 and a - 727 = 0

a = 4, 727

Now, putting the value of a in equation 3, we get

b = 731 - 4 and 731 - 727

b = 727, 4

Thus, the one digit number is 4 and three digit number is 727.

Answer:

x= 2

Step-by-step explanation:

so you add the values given in the brackets and leave X as it is (do this on both sides of the equation.

1. (x + 5)(x+4)= (x+12)(x+1)

2. multiply the parenthesis on both sides or one at a time

so,  [tex]x^{2}[/tex]+5x+4x+20 = [tex]x^{2}[/tex]+12+1x+12

3. cancel like terms which we have [tex]x^{2}[/tex] so remove that.

5x+4x+20=12+1x+12

4. collect like terms.

9x + 20 = 13x + 12

5. move like terms.

9x-13x=12-20 = -4 = -8

6. x= [tex]\frac{-4}{-8}[/tex]  divide both sides by 4 or basically simplify 4 divided by 8

which leaves u with

x= 2

The distance from the lightning strike is 4,116 meter.

What is relation between speed, distance and time?

The relation between speed, distance and time is defined as,

Distance = Speed x Time

Given that;

The speed of sound in air = 343 meters per second

Time to see lightning and hear thunder = 12 second.

Since, Distance = Speed x Time

Substitute values in above equation,

Distance = 343 x 12

             = 4,116 meter.

Hence, The distance from the lightning strike is 4,116 meter.

Step-by-step explanation:

(x, y) = (0, -7) and ((28/5 , 21/5)) , as found by solving the system of linear equations.

A system of linear equations is a set of two or more linear equations. Linear equations refer to the equations that involve two or more variables in the form of "ax + b".

Given: 2x - y = 7x² + y² = 49

to find: Values of x and y.

Finding:

Solving the system of two linear equations, by deriving the value of one variable from an equation and substituting it in the other equation and solving for the two variables.

eqn1 2x - y = 7

y = 2x - 7

eqn2  x² + y² = 49O

substituting the value of y from eqn1,

we get: x² + (2x - 7)² = 49

x² + 4x² + 49 - 28x = 49

5x² -28x = 0

x ( 5x - 28) = 0

x = 0, x = 28/5

For x = 0, y = -7 (in eqn1)=>

(x, y) = (0, 7)

For x = 28/5

y = 2(28/5) - 7

= (56 - 35) / 5

= 21 / 5

(x,y) = (28/5 , 21/5)

Hence, (x, y) = (0, -7) and (28/5 , 21/5), as found by solving the system of linear equations.

Answer:

x = 5, y = -2

Step-by-step explanation:

2x + 5y = 0 --- Equation 1

Equation 1×3: 6x + 15y = 0 --- Equation 2

3x - 4y = 23 --- Equation 3

Equation 3×2: 6x - 8y = 46 --- Equation 3

We will be eliminating 6x from Equation 2.

Equation 3-2: 6x - 8y - 6x - 15y = 46-0

-23y = 46

y = 46 ÷ -23

y = -2

Substitute y = -2 into Equation 1:

2x + 5y = 0

2x + 5(-2) = 0

2x + (-10) = 0

2x - 10 = 0

2x = 10

x = 10 ÷ 2

x = 5

The experimental design used by Betty is completely randomized experimental design. Hence, option A is correct.

A process used to confirm or deny a theory, as well as assess the effectiveness or possibility of something that has never been performed before, is called an investigation.

By showing what happens when a particular element is modified, experiments shed light on causation relationships. Experiments have a wide range of objectives and sizes, but always depend on a repeatable process and a logical examination of the outcomes. Additionally, there are experiments conducted in nature.

As Betty is wants to bake a perfect cookie, and she has enough batter. She is testing to bake the batter at different temperatures to see that what is the ideal temperature to make perfect cookies. So, this is completely randomized experimental design.
