80% of the marbles in a bag are red. There are 32 red marbles in the bag. What is the total number of marbles in the bag?

Answer:

$55.20

Step-by-step explanation:

What is the brokerage fee

.15 * 48 = 7.2

The total cost of his ticket is the price of the ticket plus the brokerage fee

total cost = 48 + 7.2

               = $55.20

Marcus had to pay a total of $55.20 for the concert ticket, which includes the 15% brokerage fee on top of the original ticket price.

Marcus bought a concert ticket for $48. The online ticket broker charged a 15% brokerage fee on top of the ticket price. To calculate the total amount Marcus had to pay, we first need to calculate the brokerage fee. The brokerage fee is found by multiplying the ticket's price by the brokerage fee rate. So, $48 multiplied by 15% (or 0.15) gives us the brokerage fee of $7.20. This brokerage fee is then added back to the original ticket price, so Marcus paid a total of $48 + $7.20 = $55.20 for the concert ticket.

Answer:

25/w = l

Step-by-step explanation:

We know that the formula for the area of a rectangle is

A = l*w

We know the area is 25

Substituting this into the equation

25 = l*w

We are to solve for l, by dividing each side by w

25/w = lw/w

25/w = l

To find the length (L) of a rectangle when the area (A) is 25 square inches, you use the formula L = A/W, substituting A with 25 and W with the given width.

To solve for the length (L) of a rectangle with a known area (A), you first need the formula for a rectangle's area, which is A = L × W, where L is the length and W is the width of the rectangle. Given that the area (A) is 25 square inches and the area formula has been incorrectly stated as A = 2LW, we should correct it to A = LW.

If you have a specific width (W), you can rearrange the formula to solve for L by dividing both sides by W, resulting in L = A/W.

Using an example, if we know the width (W) is 5 inches, we could substitute into the formula:

L = A/W

L = 25 in2/5 in = 5 in

Therefore, the length (L) of the rectangle would be 5 inches.

Answer:

The answer would be x=2

Step-by-step explanation:

Answer:

It can be written that way, but the functions are not the same. The numbers the would be plugged in would not produce the same answer.

To find the perpendicular slope, we simply flip the fraction (aka reciprocal) and flip the sign (go from positive to negative, or vice versa)

So for problem 1a) we flip the fraction to go from 4/3 to 3/4. Then we flip the sign to go from +3/4 to -3/4. The final answer to problem 1a) is -3/4

The answer to problem 1b) is 7/3 following the same basic steps: -3/7 ---> -7/3 ---> 7/3

The answer to problem 1c) is -1/4. You can think of 4 as 4/1 which flips to 1/4 and it becomes -1/4

Answer:

Country A won 78 medals

Country B won 26 medals

Country C won 15 medals

Step-by-step explanation:

We have been given with :-

A+B+C=119  _____equation(1)

B=C+11  ____equation(2)

A=B+C+37 ____equation(3)

1) Starting with the 3rd equation,

A=B+C+37

2) Subtract 37 from both sides

A-37=B+C+37-37

3) Cancelling out +37 and -37 from the right side we get,

A-37 = B+C

or

B+C = A-37

4) Plugin B+C= A-37 in the equation 1,

A+B+C = 119

=> A+(A-37) = 119

=> 2A-37 = 119

5) Add 37 to both sides

2A-37+37=119+37

6) Cancelling out -37 and +37 from the left side, we get

2A = 156

7) Divide both sides by 2

[tex]\frac{2A}{2} =\frac{156}{2}[/tex]

8) Cancelling out the 2's on the left side, we get

A = 78

9) Now, we plugin A=78 in the equation 1

A+B+C=119

=> 78+B+C=119

10) Subtract 78 from both sides

78+B+C-78 = 119 -78

11) Cancelling out +78 and -78 from the left side, we get

B+C= 41 ____let it be equation (4)

12) Subtracting C from both the sides of the equation 2, we get

B=C+11

=> B-C = C+11 - C

13) Cancelling out +C and -C from the right side, we get

B-C= 11 _____let it be equation (5)

14) Adding the equations 4 and 5, we get

B+C+B-C=41+11

15) Cancelling out the +C and -C, we get

2B = 52

16) Divide both sides by 2

[tex]\frac{2B}{2}=\frac{52}{2}[/tex]

17) Cancelling out the 2's on the left, we get

B =  26

18) Substituting A= 78 and B= 26 in the equation (1), we get

A+B+C=119

=> 78+26+C=119

=> 104+C=119

19) Subtracting 104 from both the sides, we get

104 + C - 104 = 119 -104

20) Cancelling out +104 and -104 from the left side, we get

C = 15

The problem is a basic algebra problem where we assign variables to the number of medals each country won. We then use given equations related to these variables to solve for each unknown.

In this problem, we are trying to solve for the number of medals each country won, so let's start by assigning variables for the number of medals for each country. Let's say, Country A = A, Country B = B, and Country C = C.

According to the problem, we know that Country A won 37 more medals than the sum of the other two countries, that's expressed by this equation: A = B + C + 37.

It's also stated that Country B won 11 more medals than Country C, so we have this equation: B = C + 11.

Further, we know that the total number of medals is 119, so we have this equation: A + B + C = 119.

Now, solve these equations systematically. First, substitute the value of A and B from first and second equation into the third equation and solve the variable C, then substitute the obtained value of C in second equation to find B and finally substitute the obtained values of B and C in first equation to find A.

This is a basic algebraic problem-solving situation. It involves the use of equations and variables to find the solution.

Answer:

m∡J = 110°, m∡L = 45°, m∡K = 25°

Step-by-step explanation:

Similar means they have the same angles. F corresponds with K, G with J, and  E with L.

m∡J = 110° because it corresponds with m∡G.

m∡L = 45° because it corresponds with m∡E.

To get m∡K, we have to remember all triangles add to 180. Add J and L together, and subtract that sum from 180° to get m∡F, which is equal to m∡K.

110 + 45 = 155

180 - 155 = 25

m∡K = 25°

Step-by-step explanation:

The simplified expression for (m+13)-(p+25) is m - p - 12.

To simplify the expression (m+13)-(p+25), we can distribute the negative sign to both terms inside the parentheses:

[tex]\[m + 13 - p - 25.\][/tex]

Next, combine like terms by grouping the variables (m and -p) and the constants (13 and -25):

[tex]\[m - p + 13 - 25.\][/tex]

Now, simplify the constants:

[tex]\[m - p - 12.\][/tex]

So, the final answer is m - p - 12. This expression represents the simplified form of the given algebraic expression.

In the original expression, (m+13)-(p+25), we subtracted the entire quantity (p+25) from (m+13). Distributing the negative sign, we subtracted p and 25 individually. Combining like terms involved combining the variables (m - p) and constants (13 - 25). The final result is m - p - 12, where m and p are coefficients of the respective variables, and 12 is the simplified constant term.

In summary, the expression (m+13)-(p+25) simplifies to m - p - 12 by applying the principles of combining like terms and distributing the negative sign. This simplified form is a more concise representation of the original expression.

Step-by-step explanation:

Since Farmer Tim has one of each coin, 50+20+10+5=85 cents are accounted for, leaving 395 - 85 = 310 cents for the remaining coins. We can try minimizing the number of coins that add up to 310 cents by using as many large denominations as possible.

The largest denomination is 50 cents, so we can take six 50 cent coins, which add up to 6 times 50 = 300 cents. We then can take one 10 cent coin. Thus, we have a combination of seven coins that up to 310 cents.

Therefore, the smallest number of coins that Farmer Tim could have is 4 + 7 = 11.

25(x-y) simplified using the distributive property gives us 25x - 25y.

WE are given the expression as 25x-25y

WE know that distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is

A(B + C) = AB + AC

To use the distributive property to simplify 25(x-y), we need to distribute the 25 to both x and y separately.

So,

25(x-y) = 25(x) - 25(y)

= 25x - 25y

Therefore, 25(x-y) simplified using the distributive property gives us 25x - 25y.

Final answer:

The expression 25(x-y) is simplified using the distributive property by multiplying 25 by each term inside the parentheses, resulting in 25x - 25y.

Explanation:

To use the distributive property to simplify the expression 25(x-y), you should multiply each term inside the parentheses by 25.

This is what it looks like when we apply the distributive property:

25 × (-y) = -25y

So, the simplified expression is 25x - 25y.

When we evaluate expressions, we are typically trying to express them in a way that shows the multiple or product terms explicitly. This process is like reversing distributive law and turning it back into factors (multiples). Here, the distributive law helps us see that the expressions 25x and -25y, when combined, produce the same value as the original expression 25(x-y).

Answer:

Step-by-step explanation:

First find 2 points on the line.  To do this you will need to substitute numbers in for x and y.  Do this by first putting 0 in for x to find the value of y:

9(0) + 4y = -36

0 + 4y = -36       =  4y = -36   =        y = -36 ÷ 4 = -9     y= -9

(0,-9)

Now that we have that point substitute 0 in for y.

9x + 4(0) = -36

9x + 0 = -36   =    9x = -36     =    x = -36  ÷ 9    x = -4

(-4,0)

After you have your two points decide which on you want to be (x1,y1) and which you want to be (x2,y2).  It doesn't matter which one you choose.  You will then plug in your numbers into the slope formula:

       y2 - y1           -9 - 0         -9           The slope is - 9/4

       x2 - x1            0 - 4          -4            

In a parallelogram, opposite angles are the same.

Because you are given angle C is 70 degrees, angle R is also 70 degrees.

An exterior angle of a triangle is equal to the sum of the two opposite inside angles.

Angle KSO is an exterior angle to the triangle made from ORS,

So angle KSO would equal the sum of angle O and angle R.

Angle KSO = 65 + 70 = 135 degrees.

Step-by-step explanation:

Lets start solving the equation line by line,

2/5(5+x)=8

For solving such type of question one must know the BODMAS Rule.

Where,

B= Bracket  

O=Orders

D=Division

M=Multiplication

A=Addition

S=Subtraction

and its very important to remember the priority of each operation, as you need to solve it as per their Priorities.

Bracket first, Orders second, Division and so on....

So now lets start with the given equation,

2/5(5+x)=8

As per the BODMAS we have to first start with brackets,

2/5(5+x)=8

2/5*5+2/5*x=8 First Step

2+2/5*x=8

2/5*x=8-2

2/5*x=6

2x=30

so x=15.

This is a very common Traditional Method  to solve such problems but their are other ways too.

Lets see one by one how NIco, Erik, Raj sandra and Aditi is trying to solve this question by their methods.

Lets analyze the method used by Nico first,

Nico has smartly multiplied both the sides of the equation with 5/2 so that the problem becomes easy to solve in further steps,

2/5(5+x)=8

5/2*2/5(5+x)=8*5/2

5+x=20

so x=15.

smart answer in a few steps.

Now let's analyze the answer by  Aditi,

2/5(5+x)=8

5/2*(5)+5/2=(5/2)8

The second step of Aditi is incorrect as it doesn't make any sense.

Now lets analyze the answer by Erik,

2/5(5+x)=8

2/5(5+x)-5=8-5

this will also yields a correct answer but subtracting 5 from both side doesn't seems to be a optimum way to solve and it will add more steps before getting the answer.

Raj has again using a smart way to solve the equation,

2/5(5+x)=8

1/2*2/5(5+x)=8*1/2

This will also gives correct answer in a few steps.

Sandra is using a traditional way to solve the question and it will also give correct result.

So, we can say that except Aditi all will get the correct answer.

and if we compare then Nico and Raj will get the answer in few steps.

I hope this will help you.
