Answer 1

Answer:

Equations:

[tex]4H + 3P = 13.75[/tex]

[tex]2H + 5P = 11.25[/tex]

[tex]H = 2.50[/tex] --- Hot dog

[tex]P = 1.25[/tex] --- Pretzel

Step-by-step explanation:

Represent hot dogs with H and Pretzels with P.

For Tina:

[tex]4H + 3P = 13.75[/tex]

For Doug:

[tex]2H + 5P = 11.25[/tex]

Solving for the price of both items:

We have:

[tex]4H + 3P = 13.75[/tex] --- (1)

[tex]2H + 5P = 11.25[/tex] --- (2)

Multiply (2) by 2

2 * ([tex]2H + 5P = 11.25[/tex])

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

[tex]4H + 10P = 22.50[/tex] --- (3)

Subtract (3) from (1)

[tex]4H + 3P = 13.75[/tex]

[tex]4H + 10P = 22.50[/tex]

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

[tex]4H - 4H + 3P - 10P = 13.75 - 22.50[/tex]

[tex]3P - 10P = 13.75 - 22.50[/tex]

[tex]-7P = -8.75[/tex]

Solve for P

[tex]P = \frac{-8.75}{-7}[/tex]

[tex]P = 1.25[/tex]

Substitute 1.25 for P in (2)

[tex]2H + 5P = 11.25[/tex]

[tex]2H + 5 * 1.25 = 11.25[/tex]

[tex]2H + 6.25 = 11.25[/tex]

Collect Like Terms

[tex]2H = 11.25-6.25[/tex]

[tex]2H = 5[/tex]

Solve for H

[tex]H = \frac{5}{2}[/tex]

[tex]H = 2.50[/tex]

What are the advantages and disadvantages of bar chart​

Answers

Answer:

Advantages:

● Bar charts are pretty easy to interpret, and there's a very clear relationship between size and value that allows easy comparison.

● They're simple to make and most people have experience creating and understanding them from school.

● They can help in presenting very large or very small values more emphatically.

Disadvantages:

● Bar charts that attempt to represent wide ranges of numbers will struggle to efficiently communicate their message. For example, a bar chart for the numbers 5, 6, 10 and 378 will lend extreme visual weight to the highest value and make the relative values of the other measurements appear irrelevant. An alternative to this would be creating an adjusting scale for the bars, but this complicates the visual aspect of the presentation and breaks the intuitive sense that size correlates directly to value.

● Bar graphs tend to be locked into a particular data set, making it hard to show multiple values or changes over time unless the chart is modified, such as by making the bars layered and three-dimensional.

I hope it's helpful!

Timo was curious if quadrilaterals LMNR and PQNO were similar, so he tried to map one figure onto

Timo concluded:
"It's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations,
so the quadrilaterals are not similar."

Answers

Answer:

c

Step-by-step explanation:

The two quadrilaterals LMNR and PQNO are not similar. Timo tried to map one figure onto the other using rotation and dilation methods. He concluded that they are not similar because the rigid transformations like rotation preserve congruence and dilation will not change the shape but it changes its size. So, this results in no congruence.

What is rigid transformation?Rotations, reflections, and translations are known as rigid transformations. They do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.

What is dilation?Dilation is not a rigid transformation, since they change the size of a figure. Dilation would not change the shape but changes the sizeThis would give us a similar, but not congruent figure.

Here Timo used rotation and dilation on the two quadrilaterals LMNR and PQNO. So, this resulted in a change in the size of the quadrilaterals. Because of this, Timo concluded that "it's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations, so the quadrilaterals are not similar".

how do I simify by combining like terms​

Answers

Answer:  Like terms are combined together in algebraic expression so that the result of the expression can be calculated with ease. For example, 7xy + 6y + 6xy is an algebraic equation who's like terms are 7xy and 6xy. Therefore, this expression can be simplified by combining like terms as 7xy + 6xy + 6y = 13xy + y.

Step-by-step explanation:

Answer:

If in a equation there are numbers that have the same letters you can just add them or subtract them depending on the signs.

Step-by-step explanation:

For example this equation:

2x + 7b - 7x + 9b + 1a - 22a

So you just put them in different categories(Remember to bring them with the sign that's in front of each number) after that you just add or subtract them

category x(only numbers that have x's go here):     +2x-7x  = -5x

category b (only numbers that have b's go here):    +7b+9b = +16b

category a (only numbers that have a go here):       +1s-22b = -21a

now just put them in the same equation:

-5x+16-21a

and done!^^

Hope this example helped~

If 120 L of an acid solution is 75% acid, how much pure acid is there
in the mixture?

Answers

Answer:

25% or 30L

Step-by-step explanation:

100% is 120L, we know 75% is acid, we need the other 25% to make the 100%. 25% of 120 is 30, so 30 liters is pure acid

Andy's little brother has a toy box that
contains 2 blue race cars, 1 green race car,
and 1 red race car. Andy removes 2 race cars
from the toy box without looking. If Andy
removes a blue car first and does not replace
it, which best represents the sample space
for the cars Andy removes?

Answers

Answer:

c.

Step-by-step explanation:

The solution is Option C.

Sample space is  set A = { blue , blue } , { blue , green } , { blue , red }

What is union and intersection of sets?

The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

Let the sample space be represented as set A

Now , the equation will be

The number of blue cars = 2 blue cars

The number of green cars = 1 green car

The number of red cars = 1 red car

So , the total number of cars = 2 + 1 + 1 = 4 cars

Now , Andy removes 2 race cars from the toy box without looking

Let the first removed car be a blue car

So , the second car can have any value including a blue , green or white

And , the sample space is given by set A

Set A = { blue , blue } , { blue , green } , { blue , red }

Hence , the set is { blue , blue } , { blue , green } , { blue , red }
