At a concession stand, One person purchased 3 drinks and 3 soft pretzels. Another person purchased a total of $9.00. Another person purchased 4 drinks and 2 soft pretzels for a total of $8.50. What was the price of one soft pretzel?Please help me understand how to do this question, My teacher didn't really help make sense of this.The lesson is: Application of system

Answer:

$1.75

Step-by-step explanation:

Let x be the cost of 1 drink

Cost of 3 drinks = $3x

Cost of 4 drinks = $4x

Let y be the cost of 1 soft pretzels.

Cost of 3 soft pretzels=$3y

Cost of 2 soft pretzels=$2y

Now we are given that  One person purchased 3 drinks and 3 soft pretzels. Another person purchased a total of $9.00.

So, equation becomes : 3x+3y=9  --1

Now we are given that Another person purchased 4 drinks and 2 soft pretzels for a total of $8.50.

So, equation becomes : 4x+2y=8.5--2

Solving 1 and 2 graphically

Intersection point provides the  answer of the system of equations

Refer the attached graph

Intersection point : (1.25,1.75)

Hence the price of one soft pretzel is $1.75

Answer:

Option A. 35 + 3x = 83

Step-by-step explanation:

Emma took 35 picture of flowers on a nature walk.

She took 3 pictures of each bird she saw.

If x be the number of birds she saw during her nature walk. then total picture of birds = 3x

Total pictures taken by her were = 83

Therefore, total pictures of flowers + total pictures of birds = 83

(35 + 3x = 83 )

Option A 35 + 3x = 83 is the answer.

Amount of savings that Abbey has = $1325
Fixed registration charge = $35
Then
Amount of money left in hand of Abbey = (1325 - 35) dollars
                                                               = 1290 dollars
Let us assume that with this amount of money,
Abbey can learn yoga for = x months
Then

QUESTION POSTED AT 22/01/2020 - 01:52 AM

A square picture with a side length of 4 inches needs to be enlarged. The final area needs to be 81 square inches. Which equation can be used to solve for x, the increase in side length of the square in inches? x^2 + 4x – 81 = 0 x^2 + 4x – 65 = 0 x^2 + 8x – 65 = 0 x^2 + 8x – 81 = 0

Each side of the square needs to be enlarged by x inches to obtain the new area which is 81. The area of the square is calculated by squaring the measure of its side. 
                                         A = (x + 4)²
From the given value of area,
                                          (x +  4)² = 81
                                     x ² + 8x + 16 = 81
          
Further simplification leads to the answer,
                                         x² + 8x - 65 = 0

Nash is making a framed enlargement of a Mary Cassatt postage stamp to present to a retired postmaster. He enlarges the stamp using a scale of 2 inches to 1 centimeter. If the actual length of the stamp is 3 centimeters and its width is 5 centimeters, what are the dimensions of the scale picture?

Answer: 6 by 10 inches


Step-by-step explanation:

Given: Nash is making a framed enlargement of a Mary Cassatt postage stamp to present to a retired postmaster.

The scale of enlargement is 2 inches to 1 centimeter.

The actual length of the stamp = 3 centimeters

The length of frame = 2\times3=6\ inches

The actual width of the stamp = 5 centimeters

The width of frame = 2\times5=10\ inches

Thus, the dimension fo the scale picture is 6 by 10 inches

You study for an exam, but due to the fact that you waited too long, you only learn 60% of the material. The exam is all multiple choice, with each question having 5 choices. a) If you come across a question for which you don't know the answer, what's the probability of getting the answer right? b) If you come across a question for which you do know the answer, what's the probability of getting it right? c) What is the overall probability of getting any question correct?

Answer:  a) \frac{1}{2}

b)  \frac{1}{3}

c) \frac{1}{6}

Step-by-step explanation:

The probability of a question from the material that was read = 60 % = 0.6

The probability of a question from the material that was not read = 40 % = 0.4

The probability of a right answer out of 5 questions  =\frac{1}{5} = 0.2

While, the probability of wrong answer = 1 - 0.2 = 0.8

a) Thus, by the definition of conditional probability,

The probability of getting a right answer when it is given that it is from the unread material =\frac{0.2}{0.4}=\frac{1}{2}

b) The probability of getting a right answer when it is given that it is from the read material =\frac{0.2}{0.6}=\frac{1}{3}

c) And, overall probability of a correct answer

= The correct answer is from the read material or the correct answer is from the unread material

= \frac{1}{2}\times \frac{1}{3}= \frac{1}{6}

Can someone please help me with 24? A picture step by step would be great! :)

I don't know how to draw a picture for you in this space as you asked. So, stay with me. It's a combination of BASIC geometry principles, a little algebra and, of course, simple logic.

1. Draw a vertical line from the top angle straight down. That creates 2 triangles. The newly created angles are each 90 degrees because you've created two right angles at the bottom.

2. Since the three angles of any triangle need to add up to 180 degrees, work backwards. If one angle is 90 degrees, the other two need to add up together to be 90 degrees to equal 180.

3. Start with 3x-4. Logically speaking, the angle (visually) is probably around 45 degrees because it looks like about half the size of the 90 degree angle. Start with that premise. Plug in a number to the equation that equals about that number. I chose 15. 3(15)-4 = 41. OK. If the top angle (of this newly created triangle on the left) PLUS the 41 need to add up to 90, do the subtraction.... 90-41= 49.

4. Let's move to other triangle. We know the bottom angle is 90 and PART of the top angle is 49. Again, logically and visually suppose that that far right angle is about 30 degrees - because it's skinnier than the far left 41 degree angle AND.... we could say the angle is 30 degrees because 2(15) = 30. Remember that we plugged in 15 for x in the other equation.

5. Again, do the subtraction. If one angle is 90, the second is 30, what's the difference from 180? 60. So, that top angle (of the newly-created triangle on the right is 60 .... PLUS the 49 that got from the partial angle before = 60 + 49 = 109. So the FULL angle at the top is 109 degrees. AND, we know that's right because we can check it by plugging in the number 15 into the equation like this: 8x-11.... 8(15) - 11  =  120 - 11 = 109.

6. As the measure of the largest angle is 109 degrees, the answer is B.

A probability is a number between zero and one. 

There are 3 options win, lose or draw. 
This means that (win + loss + draw = 1)

From the information given you know:
Win = 0.02
Draw = 0.8 

So: 0.02 + loss + 0.8 = 1 
Therefor loss = 1 - 0.8 - 0.02 
loss = 0.18

Hey can someone please help explain and answer this 1 question. There's a picture. Thank you!

We'll first clear a few points.
1. A hyperbola with horizontal axis and centred on origin (i.e. foci are centred on the x-axis) has equation
x^2/a^2-y^2/b^2=1
(check: when y=0, x=+/- a, the vertices)
The corresponding hyperbola with vertical axis centred on origin has equation
y^2/a^2-x^2/b^2=1
(check: when x=0, y=+/- a, the vertices).

The co-vertex is the distance b in the above formula, such that 
the distance of the foci from the origin, c satisfies c^2=a^2+b^2.
The rectangle with width a and height b has diagonals which are the asymptotes of the hyperbola.

We're given vertex = +/- 3, and covertex=+/- 5.
And since vertices are situated at (3,0), and (-3,0), they are along the x-axis.
So the equation must start with
x^2/3^2.

It will be good practice for you to sketch all four hyperbolas given in the choices to fully understand the basics of a hyperbola.

QUESTION POSTED AT 21/01/2020 - 08:56 AM

Zoro Manufacturing Company manufacturers wooden picture frames. Each piece of wood yields 15 frames. Each piece of wood costs $18.75. The direct labor charge is $13.50 per hour. Each hour, 65 frames can be produced. To the nearest cent, what is the prime cost of manufacturing one picture frame?

To determine the cost of manufacturing one picture frame, add all the known cost by the number of frames produced. With the basis of one hour of operation,

                                  Cost of wood per frame = $18.75 / 15 = $1.25

                           Cost of direct labor per frame = $ 13.50 / 65 = $ 0.21

Adding all up the costs, 

                                     total cost = $1.25 + $0.21 = $1.46

Therefore, manufacturing one picture frame costs approximately $1.46.
