If seven coins add to $1, what
could the coins be?​

Answer:

Step-by-step explanation:

i'm pretty sure that you will have to add it.

so, when we add two fractions such as 3/4 + 3/4, we make sure that the denominators (the bottom numbers) are the same and then we simply add the numerators (the  top numbers).

in this problem, the denominators are the same so we will simply add 3+3 which equals to 6/4. the denominator will remain the same.

               answer:

                      3/4 + 3/4    =   6/4

The required weight of the candy box is 3 pounds.

Given that,
A balance scale was in perfect balance when Jane placed a box of candy on one pane of the balance and 3/4 of the same-sized candy box together with 3/4 pound weight on the other pane.
To determine how much the full box of candy weighs.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Let the weight of the candy box be x,
3/4 of the same-sized candy box
weight = 3/4 pound
x = 3/4x + 3/4
x / 4 = 3/4
x = 3

Thus, the required weight of the candy box is 3 pounds.

Answer:

  $1299.50

Step-by-step explanation:

It appears that the graph shows the percentage of market value of a 6-year-old car is about 10%. So the value of such a car with an original value of $12,995 would be ...

  $12,995 × 0.10 = $1299.50

The current market value is $1299.50.

The current market value of the car is $1299.50

The original cost is given as:

Original = $12,995.

From the graph, the worth of the car after 6 years is

Rate = 10%

So, the current market value of the car is:

Value = $12,995 * 10%

Evaluate the product

Value = $1299.50

Hence, the current market value of the car is $1299.50

Step-by-step explanation:

we have

First equation

[tex]\frac{1}{2}x-\frac{1}{3}y=5[/tex]

Isolate the variable y

[tex]\frac{1}{3}y=\frac{1}{2}x-5[/tex]

Multiply by 3 both sides

Final answer:

By calculating and comparing the price per pound of meat for each shopper, it is clear that they paid different prices per pound ($3.29 and $4.19), indicating they did not buy the same kind of meat.

Explanation:

To determine if both shoppers bought the same kind of meat, we need to calculate the price per pound that each shopper paid and compare the results. The first shopper bought 3 pounds for $9.87. To find the price per pound, we divide $9.87 by 3 pounds, which gives us $3.29 per pound.

The second shopper bought 4 pounds for $16.76. Similarly, we divide $16.76 by 4 pounds to get $4.19 per pound. Since the price per pound for each shopper is different, we can deduce that they did not buy the same kind of meat.

Answer:

37

Step-by-step explanation:

Students who applied or a scholarship=95

Of that:

Men= 41

Minorities= 36

Minorities who are women= 19

Minorities who are men = 36-19=17

Women+ Minorities who are women=Students who applied or a scholarship-(Men+Minorities who are men)

x + 19=95-(41+17)

x+19=95-58

x+19=37

x= 37-19

x=18

Women who are NOT minority=18

Total women=Minorities who are women+Women who are NOT minority

Total women=18+19

Total women=37

By understanding the problem as a basic arithmetic problem, we determine there are 54 women who applied for the scholarship by subtracting the number of men (41) from the total number of students (95).

To resolve the question, 'how many women applied for the scholarship', it's essential to understand the problem as a basic addition and subtraction problem. The numbers provided in the question give us initial points. It's stated that there are 41 men who applied, and if there are 95 students in total, we can calculate the total women by subtracting the number of men from the total. So, 95 total students - 41 men = 54 women. This calculation gives us the number of women that applied for the scholarship.

Answer:

Step-by-step explanation:

hello :

a)

let  f(x) = y     so : x = g(y)

in expression = f(x) =3x+12

means : y = 3x +12  calculate : x

3x = y -12

x = (1/3)y - 4

the inverse is : g(x) = (1/3)x - 4

b)f(g(-2) = f(-14/3)

because: g(-2) = (1/3)(-2)-4 = -2/3-4 = -14/3

so : f(g(-2) = f(-14/3)=3(-14/3)+12 = - 2

1. The inverse of the function is g(x) = (1/3)x - 4.

3. The value of f(g(–2)) is -2.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f(x)= 3x+ 12

1. let  f(x) = y then x = g(y)

y = 3x+ 12

y- 12 = 3x

x= y/3 + 4

So, the inverse of the function is g(x) = (1/3)x - 4.

2. For showing the function are inverse we have to that  

(fog)(x) = f(g(x)) =x and (gof)(x) =g(f(x)) = x

Take (fog)(x) = f(g(x))

= f( (1/3)x - 4.)

= 3 ((1/3)x - 4) 12

= x - 12 + 12

= x

Now, (gof)(x)

=g(f(x))

= g(3x+ 12)

= (1/3) ( 3x+ 12) -4

= x + 4 - 4

= x

3. f(g(-2))

So,  g(-2)

= (1/3)(-2)-4

= -2/3-4

= -14/3

Then, f(g(-2)) = f(-14/3)

=3(-14/3)+12

= - 2

Final answer:

To solve the given system of linear equations, we use the elimination method to find the intersection point (14, 109), which is where the two lines represented by the equations meet.

Explanation:

To solve the system of equations:

y = 5x + 39

y = 3.5x + 60

We can use the method of substitution or elimination. In this case, elimination is the straight-forward choice. Since both equations are already solved for y, set them equal to each other and solve for x:

5x + 39 = 3.5x + 60

Now, subtract 3.5x from both sides:

1.5x + 39 = 60

Subtract 39 from both sides:

1.5x = 21

Divide both sides by 1.5:

x = 14

Now, plug the value of x into one of the original equations to solve for y:

y = 5(14) + 39

y = 70 + 39

y = 109

The solution to the system is (14, 109). This represents the point where the two lines intersect on a graph.

Answer:

The territorial dispute over Taiwan originated in 1949 when the Chinese people fled to Taiwan due to the complete control of Communists in Mainland China.

Explanation:

The event happened after the "Chinese Civil War," a war between the Kuomintang and the Communist Party of China (CPR). This resulted to many Chinese people fleeing from Southern China to Taiwan in order to prevent the advances of the Communist Party. This was also a sign of retreat from the war.

Moving to Taiwan from China took 4 months and this was meant to be a temporary solution rather than being permanent. However, the plan could not be realized thus, resulting to many Chinese people living in Taiwan until today.

So, this led to the controversial issue that Taiwan is, somehow, part of China. In connection with this, territorial disputes arose whether Taiwan should be unified with Mainland China.

Answer:

p>3

Step-by-step explanation:

<=> 3p - 9 - 5p > -3p - 6

<=> -2p + 3p > -6 + 9

<=> p > 3

To solve the inequality 3(p-3) - 5p > -3p - 6:

Simplify and combine like terms to get p > 3 as the solution.

An inequality is a mathematical statement that uses the inequality symbol to indicate the relationship between two expressions. Both sides of an inequality sign have different expressions.

The given expression is:

3(p-3) – 5p>-3p- 6

Distribute the 3 to the terms inside the parentheses:

3p - 9 - 5p > -3p - 6

Combine like terms on both sides of the inequality:

-2p - 9 > -3p - 6

Move all the terms containing p to one side by adding 3p to both sides: -2p + 3p - 9 > -6

Simplify:

p - 9 > -6

Move the constant term to the other side by adding 9 to both sides:

p - 9 + 9 > -6 + 9

Simplify: p > 3

Hence,

The solution of the given inequality is p > 3.

Step-by-step explanation:

The monthly salary for Job B after x months, which includes a 4% monthly raise, can be represented by the exponential function S(x) = 2000 * (1 + 0.04)^x, where S(x) is the salary and x is the number of months.

To represent the monthly salary for Job B after x months, we need to account for the 4% raise each month. Since the starting salary is $2000, and the raise is 4% (or 0.04 in decimal form) of the previous month's salary, the function to represent the monthly salary can be written using a geometric sequence formula.

Let S(x) be the salary at month x. The function will be an exponential function in the form:

S(x) = 2000 * (1 + 0.04)^x

Here, 2000 is the initial salary, 0.04 represents the 4% raise, and x is the number of months that have passed.

Distance in meters D = 167.75 meters

Step-by-step explanation:

Distance covered in 5 seconds is given by:

Distance, D = Speed (S) X Time (T)

Where,

Distance = ?

Speed = 75mph

Time = 5s

Since we are calculating distance in meters, we have to convert 75miles per hour to meters per second

75mph = 75miles/1hr X 1km/0.621miles X 1000m/1km X 1hr/60mins X 1min/60s

            = (75X1000) / (0.621X60X60) meter per second

            = 75000/2235.6 meter per second

            = 33.55 meter per second

∴ Distance D = 33.55 meter per second X 5 seconds

                      = 167.75 meters
