Answer:Total number of side pieces [tex] = 14[/tex]

Step-by-step explanation:

To find the number of side pieces we use formula = [tex] \frac{Area of wooden plank}{Area of 1 side piece} [/tex]

Area of wooden plank [tex]= length \times width[/tex]

Length of wooden plank [tex] =\frac{77}{8}feet =\frac{77}{8} \times 12 [/tex] inches

Length [tex] = \frac{231}{2} [/tex] inches

Width of plank [tex] = \frac{9}{16} foot = \frac{9}{16} \times 12 =\frac{27}{4}[/tex] inches

Area of plank[tex]= \frac{231}{2} \times \frac{27}{4} [/tex] sq inches

Area of 1 side piece [tex]= \frac{33}{4} \times \frac{27}{4}[/tex] sq inches

Now using formula

Number of pieces [tex]= \frac{Area wooden plank}{Area of 1 side piece} [/tex]

[tex] =(\frac{231}{2} \times \frac{27}{4} )\div (\frac{33}{4} \times \frac{27}{4}) [/tex]

Converting division into multiplication we get,

[tex] =(\frac{231}{2} \times \frac{27}{4} )\times (\frac{4}{27} \times \frac{4}{33} )[/tex]

On solving we get

[tex]= 14[/tex]

Total number of side pieces [tex] = 14[/tex]

[tex]-8x + x + 15 = -7x + 12\\\\-8x+x+7x=12-15\\\\0=-3\\\\x\in\emptyset[/tex]

There are no solutions to this equation. Hence, the solution to the given linear equation is the empty set (Ø) because simplification results in an untrue statement.

This is a linear equation, and we can solve it step by step. The first step is to simplify the equation. If we combine similar terms, we get -7x + 15 = -7x + 12. Then we can cancel the -7x from both sides of the equation, which gives us 15 = 12.

However, this statement is not true. Therefore, there are no solutions to this equation, making the solution set Ø (empty set).

Answer:

17.30 dollars

Step-by-step explanation:

Given that Payton and James mow the lawns.

They do this during summer.

The amount they spend are:

Gas  cost  = 3.50

Leaf bags =  1.20

Add these to get total costs

Total cost  = 4.70

Charge they get per lawn = 22.00

Profit = Revenue - cost

Here revenue per lawn = 22 and cost per lawn = 4.70

Hence profit = 22-4.70 = 17.30 dollars.

Answer is they make 17.30 dollars per lawn.

Answer:

The answer is B

Step-by-step explanation:

In order to check if a comparison such as this is true, you can use this logical equivalence:

[tex] \dfrac{a}{b} > \dfrac{c}{d} \iff ad > bc,\quad \dfrac{a}{b} < \dfrac{c}{d} \iff ad < bc [/tex]

Anyway, it's not always necessary to make this check. We know that every proper fraction represents a number between 0 and 1, and any improper fraction represents a number greater than 1. So, every proper fraction is less than every improper fraction.

So, the first two options are surely wrong, because they ask for a proper fraction to be more than an improper fraction.

The third option compares two proper fractions, so we actually have to check:

[tex] \dfrac{16}{26}>\dfrac{30}{31} \iff 16 \cdot 31 > 26 \cdot 30 \iff 496 > 780[/tex]

which is false.

Last option:

[tex] \dfrac{35}{30}<\dfrac{22}{12} \iff 35 \cdot 12 < 30 \cdot 22 \iff 420 < 660[/tex]

Which is true.

Final answer:

To solve the equation -2 - 3/4x = 10, you first add 2 to both sides of the equation, then multiply both sides by -4/3 to get x alone. The solution to the equation is x = -16, which is option (a).

Explanation:

To solve the equation −2 − 3/4x = 10, we need to isolate x. First, we can add 2 to both sides of the equation:

−3/4x = 10 + 2

−3/4x = 12

Next, we multiply both sides by the reciprocal of −3/4, which is −4/3 to get x alone:

(−4/3)*(−3/4)x = 12(−4/3)

x = −16

Therefore, the solution is −16, which corresponds to option (a) −16.

The value of Q that makes the system have the same solution as {(x, y) : x - 3y = 4} is Q = 8.

To find the value of Q in the given system so that the solution is {(x, y) : x - 3y = 4}, you need to make sure that the second equation, 2x - 6y = Q, is equivalent to the first equation, x - 3y = 4.

This means that the two equations have the same solution.

To do this, we can start by simplifying the second equation to be equivalent to the first one:

2x - 6y = Q

We can simplify this equation by dividing both sides by 2:

x - 3y = Q/2

Now, we want this equation to be the same as the first equation, x - 3y = 4.

To make them equal, we need to have Q/2 equal to 4.

Therefore:

Q/2 = 4

To solve for Q, multiply both sides of the equation by 2:

Q = 2 * 4

Q = 8

ANSWER

The correct answer is option D.

EXPLANATION

The given function is

[tex]k(x)=-3x^6-0.7x+x^3[/tex]

This a polynomial function. All degrees are greater than or equal to zero.

The coefficient being decimals does not disqualify it from being a polynomial.

The highest degree of this polynomial is 6.

Therefore the correct answer is D

In 63, 6 is in the tenths place, meaning it represrents the number 60.

In 46, 6 is in the ones place, meaning it represents the number 6.

So, given that, in the first example 6 is x times the value of 6 in the second example:

x = 60 / 6

x = 10

Hope it helped,

BioTeacher101

The value of the digit 6 in the number 63 is 10 times the value of the digit 6 in the number 46.

In the number 63, the 6 is in the tens place, meaning it represents 60 (6 tens). In the number 46, the 6 is in the ones place, meaning it simply represents 6 (6 ones). Therefore, the 6 in 63 is 10 times the value of the 6 in 46.

Seth:

Equation 7.50x + 15y = 750, where x is the number of hours Seth works and y is the number of lawns he mows.

Karen:

Equation 6x + 4y = 700, where x is the number of hours Karen works and y is the number of dogs she walks.

Part A: Converting it in function for by solving for y first.

Solving 7.50x + 15y = 750, equation we get

7.50x + 15y = 750

15y = -7.50x + 750

Solving 6x + 4y = 700 for y, we get

6x + 4y = 700

4y = -6x + 700

On comaring with slope-intercept form y=mx+b, we got slope for Seth equation is -1/2 and slope for Karen is -3/2.

If we take absolute of those -1/2 and -3/2 we get 1/2 and 3/2.

Therefore, Karen has the higher slope. We can see the graph that blue line has greater slope as it's increasing/decreasing with greater rate.

In function form we could write equation as

Part B : y-intercept of Karen equation is 175 and y-intercept of Seth equation is 50.

Part C: If both students work 80 hours for the month.

Let us plug x =80 in each of the equations.

Seth would earn $10 from mowing lawn.

Therefore, the number of lawns Seth has to mow = 10/15 = 0.67 that is approximately 1 lawn.

Karen would earn $50 from walking dog.

So, the number of dogs Karne has to walk = 55/4 = 13.75 that ia approximately 14 dogs.

Part D: If Karen begins charging $8 per hour for babysitting and Seth begins earning $8 per hour.

The equations would become : 8x + 15y = 750, 8x + 4y = 700.

Answer:

Seth:

Equation 7.50x + 15y = 750, where x is the number of hours Seth works and y is the number of lawns he mows.

Karen:

Equation 6x + 4y = 700, where x is the number of hours Karen works and y is the number of dogs she walks.

Part A: Converting it in function for by solving for y first.

Solving 7.50x + 15y = 750, equation we get

7.50x + 15y = 750

15y = -7.50x + 750

y = -1/2x + 50

Solving 6x + 4y = 700 for y, we get

6x + 4y = 700

4y = -6x + 700

y= -3/2x + 175.

On comaring with slope-intercept form y=mx+b, we got slope for Seth equation is -1/2 and slope for Karen is -3/2.

If we take absolute of those -1/2 and -3/2 we get 1/2 and 3/2.

Therefore, Karen has the higher slope. We can see the graph that blue line has greater slope as it's increasing/decreasing with greater rate.

In function form we could write equation as

f(x) = -1/2x + 50 and

f(x) = -3/2x + 175.

Part B : y-intercept of Karen equation is 175 and y-intercept of Seth equation is 50.

Therefore, Karen has greater y-intercept.

This means Karen earns $175 by just walking dogs.

Part C: If both students work 80 hours for the month.

Let us plug x =80 in each of the equations.

y = -1/2x + 50  => y = -1/2(80) + 50 = -40 +50 = $10.

Seth would earn $10 from mowing lawn.

Therefore, the number of lawns Seth has to mow = 10/15 = 0.67 that is approximately 1 lawn.

y = -3/2x + 175  => y = -3/2(80) + 175 = -120 +175 = $55.

Karen would earn $50 from walking dog.

So, the number of dogs Karne has to walk = 55/4 = 13.75 that ia approximately 14 dogs.

Therefore, the number of lawns Seth has to mow is less than the number of dogs Karen has to walk.

Part D: If Karen begins charging $8 per hour for babysitting and Seth begins earning $8 per hour.

The equations would become : 8x + 15y = 750, 8x + 4y = 700.

It would not effect the graph much. Even the y-intercepts would remain same.

There would be a slightly change in slopes.
