Zander uses an on-line store that sells
songs for $1 each and movies for $6.
He used all of his $20 allowance to buy
10 items.

a. Write one equation in a system for this situation.

b. Write a second equation in the system.

c. What do x and y represent?

d. How many songs and how
many movies did he buy?

Answers

Final answer:

To solve this problem, set up a system of equations and solve for the number of songs and movies Zander bought using substitution or elimination.

Explanation:

To solve this problem, we can set up a system of equations to represent the situation:

x + y = 10

$1x + $6y = $20

The first equation represents the total number of items Zander bought, which is 10.The second equation represents the total amount of money Zander spent, which is $20.x represents the number of songs Zander bought, and y represents the number of movies Zander bought.To solve the system of equations, we can use any method, such as substitution or elimination. For example, using substitution, we can solve for x in the first equation and substitute it into the second equation to find the value of y.Once we have the value of y, we can substitute it into the first equation to find the value of x.So, Zander bought 4 songs and 6 movies.

which of the following expressions represents the distances between -4 and 5 on the number line? A.|-4+5| B.|4-5| C.|-5-(-4)| D.|-4-5|

Answers

Answer:

Option C - [tex]|5-(-4)|[/tex]

Step-by-step explanation:

To find : Which of the following expressions represents the distances between -4 and 5 on the number line?

Solution :

According to number line,

<-----------|----|------|----|-----|----|---|----|----|----|-----|----|---------------->

-∞         -5   -4    -3   -2   -1   0   1    2   3   4    5    6                +∞      

The distance between -4 and 5 is given by,

[tex]d=|5-(-4)|[/tex]

Solving the expression,

[tex]d=|5+4|[/tex]

[tex]d=|9|[/tex]

[tex]d=9[/tex]

Therefore, The expression represents the distances between -4 and 5 on the number line is [tex]d=|5-(-4)|[/tex]

So, Option C is correct.

Answer:

D is the  answer

Step-by-step explanation:

|-4-5|=|-9|=9

the distance between -4 and  0  is 4 .....and between 0 and 5 is 5

so the distance will be 4+5=9

Find the percent markup from wholesale cost to selling price.

Answers

Answer:

$650 - $200 = $450

$200 = p × $450

p = 20/45 = 4/9 = about 44%

The percent markup is about 44%.

Final answer:

To find the percent markup from wholesale cost to selling price, calculate the difference between the selling price and the wholesale cost, divide that difference by the wholesale cost, and multiply by 100.

Explanation:

To find the percent markup from wholesale cost to selling price, you need to calculate the difference between the selling price and the wholesale cost, and then divide that difference by the wholesale cost. Finally, multiply the result by 100 to get the percent markup.

For example, if the wholesale cost is $50 and the selling price is $75, the difference is $25. Dividing $25 by $50 gives you 0.5, and multiplying by 100 gives you a 50% markup.

how do u solve this question 3/4 - 1/3 =

Answers

You need to find the common denominator first. 3 * 4 = 12
3/4 = 9/12 and 1/3 = 4/12
9/12 - 4/12 = 5/12
1. Find the least common denominator (12).
3/4·3/3=9/12
1/3·4/4=4/12

2. Now you can subtract.
9/12-4/12=5/12.

So your answer is 5/12.

triangles q'r's' is a translation of triangle QRS which transformation created triangle q'r's'

A. Translation 3 units left and 5 units up
B. Translation 5 units left and 3 units up
C. Translation 3 units right and 5 units down
D. translation 5 units right and 3 units down

Answers

Final answer:

To determine which transformation created triangle q'r's' from triangle QRS, one would compare the vertices of the original and translated triangles. This comparison would reveal the horizontal and vertical distances each point has been moved, indicating the correct translation.

Explanation:

The question asks which transformation created triangle q'r's' from triangle QRS. The correct answer will be the translation that moves triangle QRS to the new position of triangle q'r's'. When a figure is translated, all points move the same distance in the same direction. Given the options, we need to choose the translation that shifts the triangle in the correct direction and by the correct number of units.

Without specific coordinates, we cannot determine the exact translation from the given options. However, if we had the positions of triangles QRS and q'r's', we could compare their corresponding vertices to find the difference in their 'x' (horizontal) and 'y' (vertical) coordinates. This difference would tell us how far and in which direction the triangle has been translated.

If 1 is added to the numerator and to the denominator of a fraction,the value obtained is 4/5.If 5 is subtracted from it's numerator and from it's denominator, the resulting value is 1/2.Find the fraction.

Answers

Let n and d represent the numerator and denominator of the fraction.
.. (n +1)/(d +1) = 4/5
.. (n -5)/(d -5) = 1/2
Eliminating fractions from these equations gives
.. 5(n +1) = 4(d +1)
.. 2(n -5) = (d -5)
Subtracting the first equation from 4 times the second gives
.. 4(2(n -5)) -(5(n +1)) = 4(d -5) -(4(d +1))
.. 8n -40 -5n -5 = 4d -20 -4d -4
.. 3n = 21
.. n = 7
.. 2(7 -5) = d -5
.. 9 = d

The fraction is 7/9.

Theo bought two hot dogs and two sodas for $4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. What is the price of a hot dog at the concession stand?

Answers

Hotdog @ 0.50 cents

If Theo bought two hot dogs and two sodas for $4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. Then $1.125 is the price of a hot dog at the concession stand

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Theo bought two hot dogs and two sodas for $4.00.

Let hot dogs denoted by H

Soda denoted by S

2H+2S=4...(1)

Vicky bought three hot dogs and a soda for $4.50

3H+S=4.50..(2)

Multiply (2) with 2

6H+2S=9..(3)

Now subtract 3 from 1

2H+2S-6H-2S=4.50-9

-4H=-4.5

H=1.125

Now plug in H value in 2

3(1.125)+S=4.5

3.375+S=4.5

S=4.5-3.375

S=1.125

Hence $1.125 is the price of a hot dog at the concession stand

Rick discounts a 100-day note for $25,000 at 13%. The effective rate of interest to the nearest hundredth percent is


A. 13.48%.
B. 13.03%.
C. 13.02%.
D. 13.49%.

Answers

First we have to calculate the amount of interest. This can be done by using the interest formula, I = P x R x T.

= 25,000 x 0.13 x (100/365)
= 902.78

This will be deducted from the principal amount, which is 25,000. 

= 24,097

Last, we plug our values in to the effective rate formula for interest: 

[tex] \frac{Interest}{Proceeds x Time of Note} [/tex]

902.78/6693.6722

= 13.487066

After rounding, we come to our final answer, which is D, 13.49%.
