Really, really easy!
I know I should have figured it out, but:
Pictures from a company cost 650mb each, and songs cost 2200mb each. 16 files are downloaded in a single day, and the total mb from files downloaded adds up to 18150 mb, how many of each product was installed? Write two possible equations using p for pictures and s for songs.

Answers

Answer 1
The first equation would be 650p+2200s =18150 
The second equation would be p + s =16

Answer 2
Final answer:

This problem is a system of linear equations. The first equation represents the total number of files (pictures and songs) downloaded: p + s = 16. The second equation represents the total size of the downloads in terms of pictures and songs: 650p + 2200s = 18150.

Explanation:

This problem is an example of a system of linear equations. In this scenario, we have two types of files - pictures, represented by 'p', and songs, represented by 's'. The cost in megabytes for each is also provided. We can take these details and construct two equations:

Equation 1: The total numbers of pictures and songs downloaded: p + s = 16.
Equation 2: The total size of the downloads: 650p + 2200s = 18150.

You can solve these equations by substitution or elimination method to find the actual numbers of pictures and songs that were downloaded.

Write the vertex form of the equation of the parabola which has a vertex of (0,0) and contains the point (1,2). A. Y=2x^2. B. Y=2(x-1)^2. C. Y=x^2. D. Y=(x+1)^2+1

Answers

General equation of parabola:  y-k = a(x-h)^2

Here the vertex is at (0,0), so we have y-0 = a(x-0)^2, or y = ax^2

All we have to do now is to find the value of the coefficient a.

(1,2) is on the curve.  Therefore, 2 = a(1)^2, or 2 = a(1), or a = 2.

The equation of this parabola is y = 2x^2.

The vertex form of the equation of a parabola with a vertex at (0,0) and passing through the point (1,2) is [tex]y=2x^2.[/tex]

The vertex form of a parabola is given by: [tex]y = a(x - h)^2 + k[/tex] where (h, k) is the vertex of the parabola.

In this case, the vertex is (0, 0), so h = 0 and k = 0.

Therefore, the equation becomes: [tex]y = a(x - 0)^2 + 0.[/tex] Simplifying further, the equation becomes: [tex]y = ax^2[/tex].

Now, we need to find the value of 'a.' To do this, we can use the given point (1, 2). Substitute these values into the equation:

[tex]2 = a(1)^2[/tex].

Therefore, 'a' is 2. So, the final equation in vertex form is: [tex]y = 2x^2.[/tex]

So, the correct answer is A. [tex]Y = 2x^2.[/tex]

Step-by-step explanation:

Kurt bought a bike for $149.95. Eric bought a bike that had been $169.50 but was marked 1/5 off. How much less did Eric’s bike cost than Kurt’s?

Answers

Eric's bike costed $14.85 dollars less than kurts

After calculating the discount and subtracting it from the original price, Eric's bike cost $135.60, which is $14.35 less than Kurt's bike that cost $149.95.

To determine how much less Eric paid for his bike compared to Kurt's bike, we need to calculate the discount Eric received and subtract it from the original price of his bike. Then, we'll compare it to the price Kurt paid for his bike.

First, we calculate Eric's discount by multiplying the original price of the bike, $169.50, by 1/5 (which represents the 20% discount):

$169.50 times  15= $33.90.

Now, subtract this discount from the original price to find out how much Eric paid for the bike:

$169.50 - $33.90 = $135.60.

Finally, to find out how much less Eric's bike cost than Kurt's, we subtract the price Eric paid from the price Kurt paid:

$149.95 - $135.60 = $14.35.

Eric's bike cost $14.35 less than Kurt's.

there are 54 people at the party. 18 of them are wearing red, what percent of them are not wearing red

Answers

18 = number wearing red

54-18 = 36 not wearing red

36 out of 54 = 36/54

36/54 = 0.6666

0.6666 * 100 = 66.67%

Percent wearing red is 66.67%

There are 54 people at the party.

18 people are wearing red which means that 36 people are not wearing red

54 - 18 = 36

The fraction [tex]\frac{36}{54}[/tex] represents the 36 people at the party that are wearing no red. We can find what percent of the people at the party are not wearing red by turning [tex]\frac{36}{54}[/tex] into a percent.

[tex]\frac{36}{54}[/tex] can be reduced to [tex]\frac{2}{3}[/tex]  by dividing both the numerator and denominator by the greatest common factor of 36 and 54.

2 ÷ 3 = 0.667

0.667 × 100 = 66.67%

Therefore, 66.67% of the people at the party are not wearing red

Solve the system of equations. y = 7x + 43 y = 2x + 13 a. ( -6, 1) c. ( 6, 1) b. ( 6, -1) d. No solution

Answers

Hello there!

y = 7x + 43
y = 2x + 13

We wanna solve y = 7x + 43 for y in y = 2x + 13

What does that even mean? Well it simply means that we gonna replace y by 7x + 43.

y = 2x + 13

7x + 43 = 2x + 13

Subtract 2x on both sides

7x + 43 - 2x = 2x + 13 - 2x

5x + 43 = 13

Now we can subtract 43 on both sides

5x + 43 - 43 = 13 - 43

5x = -30

Then divide both sides by 5

5x/5 = -30/5

x = -6

Now since we have the value for x, we gonna use that value to find y.

We can do that by substituting -6 for x in y = 7x + 43

But what does that mean? It means that in y = 7x + 43, we gonna replace the x by -6

y = 7x + 43

y  = 7(-6) + 43

y = -42 + 43

y = 1

Thus,

The answer is: x = -6 and y = 1

The correct answer is option A (-6,1).

x² + x + 1/4 = - 11 3/4
x² + x + 1/4 = - 47/4

(x + 1/2)² = - 47/4 
x + 1/2 = +/- √(- 47/4) 
x + 1/2 = +/- [tex] \frac{47}{4}i [/tex]

how do i solve 3 (2y-4)=8y+9-9y

Answers

3(2y - 4) = 8y + 9 - 9y

Distribute 3:
6y - 12 = 8y + 9 - 9y

Combine like terms:
6y - 12 = -y + 9

Add y to both sides:
7y - 12 = 9 

Add 12 to both sides:
7y = 21

Divide both sides by 3:
y = 3
The first step for solving this equation is to distribute 3 through the parenthesis.
6y - 12 = 8y + 9 - 9y
Collect the like terms with y.
6y - 12 = -y + 9
Move the variable to the left side and then change its sign.
6y + y - 12 = 9
Now move the constant to the right side and change its sign.
6y + y = 9 + 12
Add the terms on the left side of the equation.
7y = 9 + 12
Add the numbers on the right side.
7y = 21
Lastly,, divide both sides of the equation by 7 to find your final answer.
y = 3
This means that y = 3 is the correct answer to your question.

Mitch does not know the correct answer to two multiple choice questions. The choices are A,B,C, and D. If Mitch just guesses, what is the probability that Mitch will guess both answers correctly?

Answers

Both chances to success are 1/4. If you want the first AND the second to be successful, you have to multiply the chances, so the answer is

1/4 * 1/4 = 1/16

Final answer:

Mitch has a 1/16 probability of guessing both multiple-choice answers correctly when randomly guessing among four options.

Explanation:

If Mitch guesses on two multiple-choice questions with choices A, B, C, and D, the probability of guessing both correctly is calculated as follows: The probability of correctly guessing one question is 1/4 (since there are 4 possible choices, and only one is correct). To find the probability of guessing both correctly, we multiply the probabilities of each independent event. Thus, the probability of guessing the first question correctly AND the second question correctly is 1/4 × 1/4 = 1/16.

Find the quotient. (14x^3-21x^2 +28x)/(7x)

Answers

The calculated quotient of the expression (14x³ - 21x² + 28x) ÷ 7x is 2x² - 3x + 4

How to evaluate the quotient expression

From the question, we have the following parameters that can be used in our computation:

(14x³ - 21x² + 28x) ÷ 7x

Factor out x in the numerator

So, we have

(14x³ - 21x² + 28x) ÷ 7x = x(14x² - 21x + 28) ÷ 7x

Evaluate the quotient

(14x³ - 21x² + 28x) ÷ 7x = (14x² - 21x + 28) ÷ 7

Divide through by 7

(14x³ - 21x² + 28x) ÷ 7x = 2x² - 3x + 4

Hence, the quotient of the expression is 2x² - 3x + 4

name the following triangle according to its angles and sides: 120 degrees, 35 degrees, 25 degrees

Answers

The answer is a scalene triangle because all its sides and angles are unequal

Final answer:

The triangle with angles of 120 degrees, 35 degrees, and 25 degrees is classified as an obtuse scalene triangle because it has one angle greater than 90 degrees and all angles of different measures.

Explanation:

To classify the triangle with angles of 120 degrees, 35 degrees, and 25 degrees, we first confirm that the sum of its angles is 180 degrees, which is true for any plane triangle. Given this sum, we can classify the triangle based on its angles and sides.

A triangle with one angle greater than 90 degrees is called an obtuse triangle, as it has an obtuse angle (greater than 90 degrees). Since this triangle has a 120-degree angle, it fits that definition. Furthermore, because all the angles are different, we can classify it as a scalene triangle, meaning all sides have different lengths. Therefore, the correct classification for this triangle is an obtuse scalene triangle.
