Find the selling price of each item Cost of a sled:99.50 Markup:95%

Answer:

37.50%

Step-by-step explanation:

Use the formula: Old Value minus New Value (in absolute value bars) divided by Old Value times 100

New Value = $25 / Old Value = $40

$40 - $25 =  $15

$15 divided by $40 is 0.375

0.375 times 100 (0.375 x 100) is 37.50

The interest Tamika earns after 15 years with an annual deposit of $1,750 in a money market account with a 4.25% annual compound interest rate is $9,449.40.

This is a problem of calculating compounded interest over time. The formula for compound interest is A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years. But since Tamika is depositing $1,750 each year, this becomes an annuity problem. So, the future value of an annuity formula is used, which is FV = P * [(1 + r)^nt - 1] / r.

Here, P = $1,750, r = 4.25% or 0.0425, n = 1 (since interest is compounded annually), and t = 15 years. Substituting these into the formula, we find FV = $1,750 * [(1 + 0.0425)^15 - 1] / 0.0425 = $35,699.40.

The total amount after 15 years is $35,699.40, but this includes her contributions which total $26,250 (1750 * 15). So, the interest she earned is $35,699.40 - $26,250 = $9,449.40.

Answer:

slope is -4 or in a fraction, -4/1

Step-by-step explanation:

When you have 2 points, you can find the slope by subtracting them by each other. You must do 8 - 0 which is 8, then -2 - 0 which is -2. Then you get 8/-2. Once simplified, you get -4, and you know if the number is alone, there is always a 1 under it so you get -4/1.

Hello!

Step-by-step explanation:

[tex]Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}[/tex]

[tex]\frac{8-0}{(-2)-0}=\frac{8}{-2}=-4[/tex]

Slope is -4

Answer: C

Step-by-step explanation: The equation is y = x/7. For every 7 numbers that x increases, y increases by 1.

Leila needs to score 23 points in her next game to have an average of 27 points per game.

To find out how many points Leila needs to score in her next game in order to have an average of 27 points per game, we need to use the formula for finding an average. The sum of all the points scored is 33 + 28 + 24 + x (the points in the next game), and we divide this sum by the number of games, which is 4. So, the equation is (33 + 28 + 24 + x) / 4 = 27. To solve for x, we multiply both sides of the equation by 4 to get 33 + 28 + 24 + x = 27 * 4. Simplifying this gives us 85 + x = 108. To isolate x, we subtract 85 from both sides of the equation, which gives us x = 108 - 85. So, Leila needs to score 23 points in her next game to have an average of 27 points per game.

where b is the y intercept

y = mx+2

The only answer that has the y intercept of 2 is y = 3x+2

Answer: B) 1/4

The greatest common factor of 4 and 16 is 4. This is the largest factor that goes into both numerator and denominator

Divide the numerator and denominator by the GCF

4/4 = 1

16/4 = 4

This means 4/16 reduces to 1/4

Thinking in reverse, you can multiply top and bottom of 1/4 by 4 to get 4/16.

Answer:

nth term =  523 + 24(n - 1

Step-by-step explanation:

This is modelled by an arithmetic series where first term a1 = 523 and common difference d = 24.

nth term = a1 + d(n - 1).

Here it is  523 + 24(n - 1)   (answer)

Answer:

The answer is:24n+499

Step-by-step explanation:

As we know Henry's grandfather gave him a box of 523 baseball cards in the first month.

from the second month Henry start to collect 24 baseball cards each month.

if the total process took n months, so Henry himself collected 24 baseball cards for 'n-1' months.

so total cards collected by Henry in (n-1) months is=24(n-1)

hence, Henry's total collection is=number of baseball cards his grandfather gave him+number of baseball cards collected by Henry himself

=523+24(n-1)

=523+24n-24

=24n+499

Answer: 31 & 42

Step-by-step explanation:

1st #: x

2nd #: x + 11

1st# + 2nd# = sum

 x    +  x + 11 =  73

         2x + 11 = 73

         2x        = 62

           x          = 31

2nd #: x + 11   = 31 + 11   = 42

The problem is solved by creating two equations from the given conditions and then solving them to find the numbers. The result is that the two numbers are 31 and 42.

We are looking for two numbers, let's call them x and y. According to the problem, one number exceeds the other by 11, so we can say that y = x + 11. Moreover, their sum is 73, so x + y = 73.

Now, we need to substitute y from the first equation into the second one. So x + (x + 11) = 73, which simplifies to 2x + 11 = 73. Subtracting 11 from both sides gives us 2x = 62. Dividing by 2, we find that x = 31. From the first equation, we can now determine the value for y as y = 31 + 11 = 42. Therefore, the two numbers are 31 and 42.

Answer:

slope = -7/2

Step-by-step explanation:

To find the slope, we will solve the equation for y.

7x-2y=0.2

Subtract 7x from each side.

7x-7x-2y=-7x+0.2

-2y = -7x+0.2

Then we need to divide each side by -2

-2y/-2 = -7x/-2 + 0.2/-2

y = -7/2 x -0.1

This is in the form y= mx+b where m is the slope and b is the y intercept.

So the slope is -7/2 and the y intercept is -0.1

Answer:

The row with x = 2 and y = 4 is incorrect. The y value should be y = 3 when x = 2.

==============================================================

Explanation:

Fractions can be a bit of a pain, so I'm going to be converting to decimal form to help with the computation; however, I will convert the y value results to mix number form so that it matches what the table shows.

Keep in mind that 3/4 = 0.75 when you use a calculator or long division. So a number like 2.75 means 2 & 3/4 (two and three quarters)

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

Let's check the first row. Plug in x = 0 and it leads to...

y = (3/4)*x^2

y = (3/4)*0^2

y = (3/4)*0

y = 0.75*0

y = 0

This shows us that row 1 is correct. When x = 0, y = 0 leading to (x,y) = (0,0).

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

Repeat the same basic outline of steps, but now use x = 2

y = (3/4)*x^2

y = (3/4)*2^2

y = (3/4)*4

y = 0.75*4

y = 3

So instead of 4, the proper y value is y = 3 when x = 2. This means row 2 is the answer (the row that has the incorrect values).

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

For the sake of completeness, let's see if the third row is correct or not. Plug in x = 3

y = (3/4)*x^2

y = (3/4)*3^2

y = (3/4)*9

y = 0.75*9

y = 6.75

y = 6 & 3/4

We see that x = 3 points to y = 6 & 3/4, so we have the correct values in this row. We can cross this off the list of choices.

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

Finally, let's check x = 5

y = (3/4)*x^2

y = (3/4)*5^2

y = (3/4)*25

y = 0.75*25

y = 18.75

y = 18 & 3/4

We get the proper y value. So we can also cross this off the list.

Answer:

A

Step-by-step explanation:

C and D are both wrong for the same reason. The denominator should be (x +1)*5 which means that either A or B is correct.

C and D have an error seldom seen on Brainly. It means that the denominator has been added rather than multiplied but even the addition is a little strange. Frankly, I don't know what has to be done to get either of them.

So the answer is

numerator: 5*(x + 9) +  (x + 1)(x - 2)

denominator: 5*(x + 1)

Simplify the numerator. Remove the brackets.

numerator: 5x + 45 + x^2 - 2x + x - 2               Gather like terms

numerator: x^2 + 5x - 2x + x + 43                      Simplify

numerator: x^2 + 4x + 43

Answer

x^2 + 4x + 43

5(x + 1)

y-coordinate is 3 times the x-coordinate → y = 3x

Substitute to the equation 3x - 4y = 9:

3x - 4(3x) = 9

3x - 12x = 9

-9x = 9     divide both sides by (-9)

x = -1

y = 3(-1)

y = -3

The point of x and y-coordinate after solving the equation is (-1, -3).

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both.

Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given equation in the question,

3x - 4y = 9  (i)

It is given that y is three times the x-coordinate,

y = 3x

Substitute it in equation (i)

3x - 4(3x) = 9

3x - 12x = 9

-9x = 9

x = -1

Substitute x = -1 in equation (i)

3(-1) - 4y = 9

-4y = 12

y = -3

Therefore, the point is (-1, -3).

now, if you took a look at that link above, let's see.

if we take AB and BC and lie them flat, by opening up the vertex at B, the longest that'd give us is 12+14 = 26, so AC can be at most LESS than 26 units, because if it's 26, then we end up with a flat-line and lose the triangle, so 25 or less is fine for AC.

can it be 30? well, how the dickens are AB + BC going to give 30 or more than 30 really?  nope, not quite, it can't be.
