Answer:

(TZ - 2P)/2 = S

Step-by-step explanation:

Multiply both sides by Z

T*Z = Z*2(S + P)/Z

TZ = 2*(S + P)                    Divide by 2

TZ/2 = 2(S + P)/2              Do the division

TZ/2 = S + P                      Subtract P from both sides

TZ/2 - P = S                       That's one answer. You could refine it.

Multiply P by 2 so that you can put TZ - 2P over a common denominator.

(TZ - 2P)/2 = S                   Is another answer.  

I think the second one is probably the best one.

Answer:it would take him five weeks to lose ten pounds

Step-by-step explanation:

Answer: To determine Rocco´s weight jake must use this expression

Step-by-step explanation:

Hi to solve this problem we have to analyze the information given:

So, we have to write an equation where p is Rocco's weight after w weeks.

Each week Rocco will lose 0.5 pounds so the expression is 0.5w, where w is the number of weeks.

Mathematically speaking:

By replacing w by the number of weeks, Jake will obtain Rocco´s weight.

For example, if the number of weeks is 20:

p= 55-0.5x 10

p= 55 - 20

p= 35

After 20 weeks Rocco will lose 10 pounds.

Answer:

to find the vertical asymptote, you have to put the rational function in the simplest form, which means to cancel any common factor between the numerator and denominator. here we don't have anything to cancel. then take the denominator and equal it to 0. x-3=0 ,x=3

to find the horizontal asymptote, in this situation, the degree of the numerator and denominator are the same which is 1. therefore, y=the coefficient of the numerator ÷ the coefficient of the denominator. y=6÷1 ,y=6

Answer with explanation:

The given function is:

   [tex]f(x)=\frac{6x-2}{x-3}[/tex]

Horizontal Asymptote

   [tex]y= \lim_{x \to \infty} \frac{6x-2}{x-3}\\\\\text{Dividing Numerator and Denominator by ,x}\\\\\Rightarrow y=\lim_{x \to \infty} \frac{6-\frac{2}{x}}{1-\frac{3}{x}}\\\\\Rightarrow y=\frac{6-0}{1-0}\\\\\Rightarrow y=6[/tex]

Vertical Asymptote

→Substitute Denominator of f(x) =0

⇒x-3=0

⇒x=3

⇒x=3 is Vertical Asymptote , and y=6 is horizontal Asymptote.

Answer:

9y +9x - 10a-10c -10b = 105

Step-by-step explanation:

Given

a+b+c = -6 and x+y = 5

We have to find 9y +9x - 10a-10c -10b

Rearranging the terms

9x+9y-10a-10b-10c

Simplifying will give us:

= 9 (x+y) - 10(a+b+c)

Putting the values of x+y and a+b+c

= 9(5) -10(-6)

=45+60

=105

Therefore,

9y +9x - 10a-10c -10b = 105 ..

Answer:

9y + 9x - 10a - 10c - 10b  = 105

Step-by-step explanation:

It is given that,  a+ b + c = - 6 and x + y = 5

To find the value of given expression

Let the expression be 9y +9x - 10a-10c -10b

9y +9x - 10a -10c -10b  = 9(y + x) - 10(a + c + b )

 = 9(x + y) - 10(a + b + c)

 = 9 * (5) - 10 * (-6)

 = 45 + 60

 = 105

Therefore 9y + 9x - 10a - 10c - 10b  = 105

Answer:

there are no extraneous solutions to the equation

Step-by-step explanation:

Given

[tex]\sqrt{8x+9}[/tex] = x + 2 ( square both sides )

8x + 9 = (x + 2)² ← expand

8x + 9 = x² + 4x + 4 ( subtract 8x + 9 from both sides )

0 = x² - 4x - 5 ← in standard form

0 = (x - 5)(x + 1) ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 1 = 0 ⇒ x = - 1

As a check

Substitute these values into the equation and if both sides are equal then they are the solutions.

x = 5 : [tex]\sqrt{8(5)+9}[/tex] = [tex]\sqrt{49}[/tex] = 7

right side = 5 + 2 = 7

left side = right side ⇒ x = 5 is a solution

x = - 1 : [tex]\sqrt{8(-1)+9}[/tex] = [tex]\sqrt{1}[/tex] = 1

right side = - 1 + 2 = 1

left side = right side ⇒ x = - 1 is a solution

There are no extraneous solutions

Answer:

There are no extraneous solutions

Step-by-step explanation:

sqrt(8x+9) = x+2

Square each side

(sqrt(8x+9))^2 = (x+2)^2

8x+9 =  (x+2)^2

FOIL

8x+9 = x^2 +2x+2x+4

Combine like term

8x+9 = x^2 +4x+4

Subtract 8x from each side

8x-8x+9 = x^2 +4x-8x+4

9 = x^2 -4x+4

Subtract 9 from each side

0 = x^2 -4x-5

Factor

0=(x-5) (x+1)

Using the zero product property\

x-5 =0  x+1=0

x=5   x=-1

Check the solutions

x=5

sqrt(8*5+9) = 5+2

sqrt(40+9) = 5+2

sqrt(49) =7

7=7

x=-1

sqrt(8*(-1)+9) = -1+2

sqrt(-8+9) = -1+2

sqrt(1) =1

1=1

Both solutions are true solutions

Answer:

11 cartons

Step-by-step explanation:

Number of large boxes that can be contained in a carton = 8

Number of small boxes that can be contained in a carton = 10

Total number of boxes sent in one shipment = 96

This shipment contains both large and small boxes. Let there be x cartons of large boxes and y cartons of small boxes in one shipment. So, we can say,

Total number of large boxes in one shipment = Number of boxes in one carton * Total number of cartons = 8x

Similarly,

Total number of small boxes in one shipment = 10y

Since, total number of boxes in one shipment is 96, we can set up the equation as:

8x + 10y = 96

This equation can have following possible solutions:

We are given in the statement that are more large boxes than the small boxes, the valid solutions are:

Assuming that he sent both large and small boxes, the only valid solution will be:

This means, the merchant sent 7 cartons of large boxes i.e. 56 large boxes and 4 cartons of small boxes i.e. 40 small boxes. So in total he sent 11 cartons.

Answer:

11 boxes total   4 small    7 large  

Step-by-step explanation:

1 small box *10 = 10             96-10 = 86 (NO MULTIPLE OF 8)

2 small boxes*10=20          96-29=76 ( no multiple of 8)

3 small boxes  *10=30        96-30= 66(no multiple of 8)

4 small boxes*10 = 40        96-40 = 56 (YES multiple of 8)      56/8 = 7   (7 large boxes)

4 large boxes and 7 large boxes

Answer:

The border will be 18.6 inches wide

Step-by-step explanation:

Let the width be w

The length = 43 inches

Total wood = 800 square inches

Formula for area of rectangle = length x width

800 = 43 x w

w = 800/43

w = 18.6 inches

Therefore, the border will be 18.6 inches wide.

!!

Answer:

5 inches

Step-by-step explanation:

Let x be the width ( in inches ) of the border,

Given,

The length of the picture = 43 inches,

And, width of the picture = 27 inches,

So, the length of whole frame ( picture with border ) = 43 + 2x,

Its width = 27 + 2x

Thus, the area of the whole frame,

[tex]A=(43+2x)(27+2x)-----(1)[/tex]

Now, the area of the picture,

[tex]A_1=43\times 27=1161\text{ square inches}----(2)[/tex]

We have, the area of the border,

[tex]A_2=800\text{ square inches}----(3)[/tex]

Thus,

[tex]A=A_1+A_2[/tex]

Equation (1) (2) and (3),

[tex](43+2x)(27+2x) = 1161+800[/tex]

[tex]1161 + 86x+54x+4x^2=1161+800[/tex]

[tex]4x^2+140x-800=0[/tex]

[tex]x^2+35x-200=0[/tex]

[tex]x^2+40x-5x-200=0[/tex]

[tex]x(x+40)-5(x+40)=0[/tex]

[tex](x-5)(x+40)=0[/tex]

[tex]\implies x=5\text{ or }x=-40[/tex]

∵ Width can not be negative,

Hence, the width of the border is 5 inches.

Answer:

Step-by-step explanation:

Answer:

-6/7

Step-by-step explanation:

To find the slope of a line given two points on that line, you can use the slope formula: [tex]\frac{y_2-y_1}{x_2-x_2}[/tex] where you have points [tex](x_1,y_1) \text{ and } (x_2,y_2)[/tex].  

When using that formula, do not put the subscripts when plugging in the answers.

Something that is equivalent to that formula and I think is easier to remember is:

Lining up the points and subtracting vertically and then putting 2nd difference over first difference.

Like this:

 (-2 ,  3)

- ( 5 , -3)

-------------

-7         6

So the slope is 6/-7 or -6/7.

It doesn't matter what order you do the points. You have done the (5,-3) on top instead.

Like this:

  ( 5, -3)

-  (-2,  3)

--------------

  7     -6

The slope is still -6/7.

If you don't like that and you do just directly like using that formula, then I will do it that way too.

So applying the formula either gives you: [tex]\frac{3-(-3)}{-2-5)}[/tex] or [tex]\frac{-3-3}{5-(-2)}[/tex].  Both will give us the same number.

[tex]\frac{3-(-3)}{-2-5)}=\frac{6}{-7}=\frac{-6}{7}[/tex]

[tex]\frac{-3-3}{5-(-2)}=\frac{-6}{7}[/tex]

Answer:

Step-by-step explanation:

a)

y=−1/12x^2+6x+3

y=−1/12(0)^2+6(0)+3

y = 3

b)

y=−1/12x^2+6x+3

y = -1/12 (x^2-72x) + 3

y = =-1/12 (x^2-72x+1296-1296) +3

y = -1/12(x^2 -72x +1296) + 108 + 3

y = -1/12 (x - 36)^2 +111

maximum height of the ball is 111 feets

c)

y = -1/12 (x - 36)^2 +111

0 = -1/12 (x - 36)^2 +111

-111 = -1/12 (x - 36)^2

1332 = (x - 36)^2

36.497 = x - 36

x = 72.497

How far from the child does the ball strike the ground = 72.497 feets

The ball is 3 feet high when it leaves the child's hand. The maximum height of the ball is 6 feet. The ball strikes the ground 2 feet from the child.

(a) To find the height of the ball when it leaves the child's hand, we need to substitute x=0 into the equation for y. Therefore, y=(-1/12)(0)^2+6(0)+3=3. So, the ball is 3 feet high when it leaves the child's hand.

(b) The maximum height of the ball can be found by determining the vertex of the parabolic equation. The equation is in the form of y=ax^2+bx+c, where the vertex is located at x=-b/2a. In this case, a=-1/12 and b=6. Therefore, x=-6/(2(-1/12))=-6/(-1/6)=-6(-6)=6 feet. So, the maximum height of the ball is 6 feet.

(c) To determine how far from the child the ball strikes the ground, we need to find when the ball's height is 0. Set y to 0 and solve for x. 0=(-1/12)x^2+6x+3. This equation can be solved using factoring or the quadratic formula. The solutions are x=-36 and x=2. Therefore, the ball strikes the ground 2 feet from the child.

5500% of 4600% is 2530

Order of Operations in Mathematics follow this following rule :

This problem is about Percentage.

Given:

What percent of 4600% is 2530?​

We can translate above questions into mathematical equation as follows:

[tex]x\% \times 4600 \% = 2530[/tex]

[tex]x\% \times \frac{4600}{100} = 2530[/tex]

[tex]x\% \times 46 = 2530[/tex]

[tex]x\% = 2530 \div 46[/tex]

[tex]x\% = \frac{55}{1}[/tex]

To convert above fraction , we could multiply with 100% :

[tex]x\% = \frac{55}{1} \times 100\%[/tex]

[tex]x\% = \boxed{ 5500 \% }[/tex]

Another Example:

50% of 4600 is 2300

80% of 4600 is 3680

100% of 4600 is 4600

120% of 4600 is 5520

The 2530 is 55% of 46. This means that 2530 is 55% of 4600%, as 4600% is equivalent to 46 in decimal form.

To find what percent 2530 is of 4600%, we first need to understand that 4600% is equal to 46. Hence, we need to determine what percent of 46 is 2530.

Let x be the percentage we are trying to find. We can set up the equation:

x% of 46 = 2530

To solve for x, we divide both sides by 46:

x% = 2530 / 46

x% = 55

So, 2530 is 55% of 46.

To summarize, 2530 is 55% of 46. This means that 2530 is 55% of 4600%, as 4600% is equivalent to 46 in decimal form.

Answer: True

Step-by-step explanation: that is the correct definition on theoretical probability! :D

. Probability is calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes, not unfavorable outcomesThe statement about theoretical probability in the question is false.

The provided statement about theoretical probability is false. According to the definition of theoretical probability, the probability of an event occurring is in fact the number of favorable outcomes divided by the total number of possible outcomes, not the unfavorable outcomes. To calculate the theoretical probability of an event A, one must count the number of outcomes that are favorable for event A (those that result in the event occurring) and divide by the total number of all possible outcomes.

Example:

If a die is rolled, the probability of rolling a three (a favorable outcome) is 1 in 6 (the total number of possible outcomes), as there is one three on a die and six possible outcomes in total.

Therefore, the correct way to express probability is:

Probability = (number of favorable outcomes) / (total number of possible outcomes)

Step-by-step explanation:

There are four 11-year olds and x amount of 14-years old.

We are given the average of this group of 11 and 14 year olds is 12.

This gives us the following equation to solve for x:

[tex]\frac{4(11)+x(14)}{4+x}=12[/tex]

Doing some simplifying on the left and writing 12 as 12/1 on the right because I'm going to cross-multiply in the step to follow:

[tex]\frac{44+14x}{4+x}=\frac{12}{1}[/tex]

Cross multiplying:

[tex]1(44+14x)=(4+x)(12)[/tex]

Distribute:

[tex]44+14x=48+12x[/tex]

Subtract 12x on both sides:

[tex]44+2x=48[/tex]

Subtract 44 on both sides:

[tex]2x=4[/tex]

Divide both sides by 2:

[tex]x=2[/tex]

Answer:

The distance formula d = rt, 'd' stands for distance, 'r' stands for rate and 't' stands for time.

It's a well known formula used in physics to solve problems that involves questions like "how fast", "how far", or "for how long".

In the formula d = rt, the variable t represents time. It's a consistent representation across situations whenever you are dealing with equations for motion, speed, or other physics contexts.

The variable t in the formula d = rt stands for time. This formula is used to calculate distance based on the rate of speed (r) and the time (t) traveled. To solve for time, you would rearrange the formula to t = d/r, which means time equals distance divided by rate.

In various physics and mathematical contexts, as shown in the reference information, the letter t consistently represents time. It could be the time an object takes to cover a certain distance at a given rate, or more complex scenarios involving non-Euclidean worlds or quantum mechanics. Nevertheless, whenever you see t in such equations, it is typically referring to time, unless otherwise specified.
