having trouble please help I WILL MARK BRAINLYEST

Since the box represents a proportional relationship, the empty box would be = 22.

When proportional relationship exists between two variables, it means that a particular value would be times with one variable to give the next compared variable.

For example, using the figures given above;

8 pages of notes = 16hours

1 page = 16/8 = 2 hours

Therefore, each page should be times by two to give the number of hours.

Answer:

He saves $7.50

Step-by-step explanation:

30% of 25

= 0.30 * 25

= 7.50

Answer:

$7.50

Step-by-step explanation:

To find this number you would use [tex](\frac{3}{10} *25)[/tex] or [tex]25(0.3)[/tex] because you are basically finding 30% of 25. This would get you $7.50.

Answer:

f'(x) = 18x² - 18x + 12

Step-by-step explanation:

Differentiate using the power rule

[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]

Given

f(x) = (3x² + 6)(2x - 3) ← expand factors using FOIL

     = 6x³ - 9x²  + 12x - 18 , then

f'(x) = 3.6x² - 2.9x + 12

      = 18x² - 18x + 12

Answer:

n5 + 17

Step-by-step explanation:

They're asking for a pattern.

17 + 5 = 22

22 + 5 = 27

27 + 5 = 32

So it starts at 17 and increases by five each time.

The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.

n5 + 17

Answer: Forgot to divide at the end

Step-by-step explanation:

To figure out your friend's error, solve the equation yourself.

When we do this, we realize adding 3 would make it 33. This shows that the friend likely forgot to divide by 25 to completely isolate x, and stopped at that step.

Answer:

z = 77

Step-by-step explanation:

Given

[tex]\frac{z}{7}[/tex] - 9 = 2 ( add 9 to both sides )

[tex]\frac{z}{7}[/tex] = 11 ( multiply both sides by 7 to clear the fraction )

z = 77

Answer:

Yes

Step-by-step explanation:

Let's say each letter was a different number. When it comes to multiplication the order doesn't matter, plus the numbers that are together are just number multiplied.

Example:

(1)(2)(3)*(4)(10)Equals 240

If you switch those around, no matter what it will equal 240

Answer: They are equivalent

Both expressions have one copy of v, w, x, y, and z in some order all being multiplied. We can multiply any two numbers in any order we want

a*b = b*a

For example,

2*3 = 3*2

Since both equal 6.

We can extend this idea out to more than two things being multiplied and the order still doesn't matter. This idea is the commutative property of multiplication.

Answer: 15 boxes

Step-by-step explanation:

From the question, we are informed that Denise wants to cover a 21.75 square foot wall with weathered wood and that each box of weathered wood contains 1.5 square feet of wood.

The number of boxes of weathered wood that she need will be calculated by dividing 21.75 square feet by 1.5 square feet. This will be:

= 21.75/1.5

= 14.5

= 15 boxes approximately

Answer:

Step-by-step explanation:

Step one:

given data

diameter of circle= 12 in

the radius is r=d/2=6in

the area of the circle is

A=πr^2

A=3.142*6^2

A=3.142*36

A=113.1in^2

If the circle is folded in half, the area will be A/2= 113.1/2= 56.55in^2

In the corresponding shape is folded again the area is A/4= 28.3in^2

The expression for the last shape is

A= πr^2/4

1. Sry, I am confused by this one

2. Positive Integer factors of 196 = 2, 4, 7, 28, 196/2, 2, 7, 7, leaves it with no remainder.

3. Neither

4. Prime

5. Composite

Answer:

The initial height would be the intersection between the line and the y-axis, or the y-intersect

Step-by-step explanation:

Initial height means the height before any time has passed, so the x-axis representing time must have a value of 0. Because of this the initial height is the y-intercept.
