Step-by-step explanation:

step 1. y = mx + b. (slope intercept form)

step 2. y = (rise/run)x + (y intercept)

step 3. y = (5/3)x + 0

step 4. y = (5/3)x

Answer:

a) 6 cups

Step-by-step explanation:

We can use a ratio for this:

sugar : flour

2 : 3

x : 9

2       3

---  =  ---

x        9

Cross multiply:

2 (9) = 3x

18 = 3x

6 = x

x = 6

To double-check, you can plug the value back into the ratio and make them fractions, then simplify to see if it gets the original amount. Here's what I'm talking about:

2 : 3

x : 9     ======>     6 : 9

[tex]\frac{6}{9} \frac{/3}{/3} = \frac{2}{3}[/tex]

Answer:

(-3,29)

Step-by-step explanation:

If you're wanting it alone just with the exponents, here is how you're going to do it:

Technically, the 2 alone has a power, and it's simply just one. When exponents are being used in numbers multiplying together, they add.

So, to simplify this it'd be 2^5.

If you're wanting the actual answer, you would do exponents first. Remember that exponents are just the number being multiplied by itself x times:

                                   2 x 2 x 2 x 2 = 16

Now we just need to multiply this by 2 and you'll get 32.

OR, if you do the 2^5, you'll still get 32!

hi here it is

Step-by-step explanation:

the area is squared

Answer:

x = 12 and y = 31

Step-by-step explanation:

Hey There!

So the two angles with x are interior angles meaning that they are congruent

So to solve for x we use the equation

3x+17=5x-7

step 1

add 7 to each side

17+7=24

-7+7 cancels out

now we have

3x+24=5x

step 2 subtract each side by 3x

3x-3x cancels out

5x-3x=2x

were left with

2x=24

final step divide each side by 2

24/2=12

2/2 cancels out

x=12

now we plug it into one of the expressions

3x12=36

36+17=53

the angle that is equal to 53 is supplementary to the angle with y meaning that they add up to 180

so to solve for y we use this equation

180=4y+3+53

step 1 combine like terms

53+3=56

now we have

180=4y+56

step 2 subtract each side by 56

180-56=124

124=4y

step 3 divide each side by 4

124/4=31

y=31

so we can conclude that

x=12 and y = 31

Answer:

[tex]Amount = 66ft^3[/tex]

Step-by-step explanation:

No attachment given, but the question can still be solved.

Given

Cuboid 1

[tex]Length = 1ft[/tex]      [tex]Width = 1ft[/tex]      [tex]Height = 2ft[/tex]

Cuboid 2

[tex]Length = Width = Height = 4ft[/tex]

Required

How much plaster can fit in

To do this, we simply calculate the volume of the shape

For cuboid 1

[tex]Volume = Length * Width * Height[/tex]

[tex]V_1 = 1 * 1 * 2[/tex]

[tex]V_1 = 2ft^3[/tex]

For cuboid 2

[tex]V_2 = 4 * 4 * 4[/tex]

[tex]V_2 = 64ft^3[/tex]

Amount of plaster is then calculated as:

[tex]Amount = V_1 + V_2[/tex]

[tex]Amount = 2ft^3 + 64ft^3[/tex]

[tex]Amount = 66ft^3[/tex]

Answer:

12

Step-by-step explanation:

Simplifying

18x + -6y = 12

Solving

18x + -6y = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6y' to each side of the equation.

18x + -6y + 6y = 12 + 6y

Combine like terms: -6y + 6y = 0

18x + 0 = 12 + 6y

18x = 12 + 6y

Divide each side by '18'.

x = 0.6666666667 + 0.3333333333y

Simplifying

x = 0.6666666667 + 0.3333333333y

Answer:

The scale factor is (0.5)

Step-by-step explanation:

[tex] \frac{2}{4} = \frac{1}{2} \\ \frac{3}{6} = \frac{1}{2} \\ \frac{4}{8} = \frac{1}{2} \\ so \: the \: scale \: factor \: is \: \frac{1}{2} = 0.5[/tex]

Answer:

number of people=4+1

=5

144/5=28.5

28×5=140

Step-by-step explanation:

how many pencils will be left over?=144-140

=4

After sharing 144 pencils equally among 5 people they left with 4 pencils.

Given that, Terry has a box of 144 colored pencils.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Terry and 4 of his friends share the pencils equally

So, including terry there are 5 people

Here,

5|144|28

  10
______

    44
    40
______
      4

Each of the them get 28 pencils, after sharing equally, they left with 4 pencils

Therefore, after sharing 144 pencils equally among 5 people they left with 4 pencils.

Answer:

Answer:

it's only the last two

Step-by-step explanation:

3x + 2 = 25

3x + 2 - 2 = 3x

25 - 2 = 23

3x = 23

3x / 3 = x

23 / 3 = 7 2/3

x = 7 2/3 not this one

x/3 + 7 = 8

x/3 + 7 - 7 = x/3

8 - 7 = 1

x/3 = 1

x/3 * 3 = x

1 * 3 = 3

x = 3 not this one

4 + 5x = 18

4 + 5x - 4 = 5x

18 - 4 = 14

5x = 14

5x / 5 = x

14 / 5 = 2 4/5 not this one

24 - 2x = 13

24 - 2x - 24 = -2x

13 - 24 = -11

-2x = -11

-2x / -2 = x

-11 / -2 = 5 1/2 not this one

81/x - 3 = 6

81x - 3 + 3 = 81/x

6 + 3 = 9

81/x = 9

81/x * x = 81

9 * x = 9x

81 = 9x

81 / 9 = 9

9x / 9 = x

9 = x this one

2x - 3 = 15

2x - 3 + 3 = 2x

15 + 3 = 18

2x = 18

2x / 2 = x

18 / 2 = 9

x = 9 this one

Answer:

d. a power analysis; tells the researcher the number of participants needed for trustworthy results.

Step-by-step explanation:

A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.

A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.

This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

Before hypothesis testing and at the beginning of a study, a researcher is advised to conduct a power analysis because it tells the researcher the number of participants needed for trustworthy results.

A power analysis should always be conducted before the collection of data because it will help you as a researcher to determine the smallest sample size that's accurate enough to detect the effect of a specific test at the desired statistical significance level.
