matilda mixed 8 parts cranberry juice with 4 parts apple juice to make cran-apple juice. what is the ratio of cranberry juice to apple juice in the mixture?

please explain how you got the answer

Answers

The ratio of cranberry juice to apple juice is 2:1 or 2 to 1

Both 8 and 4 can be divided by 4 so divide (cranberry juice—>) 8 by 4 to get 2. Divide (apple juice—>) 4 by 4 to get 1, now put them in the correct spot which equals 2:1 or 2 to 1

a tennis shop sold twenty $100 racquets at an 8% profit and ten $80 bags at a 15% loss. The profit on the combined transaction was


PLEASE HELP. I'LL GIVE THE BRAINLIEST.

Answers

So first let me assume that the Total profit of the racquets are 8 percentage and not individually.

Now to find the profit we can do

20 x 100= 2000

Now
8=x/2000*100
X= 160

And now for loss
10x80=800

Now

15= x/800*100
X=120

Now profit =

160-120 = 40

The profit was only 40

Answer:

$ 40

Step-by-step explanation:

Rackets:

      Cost Price (CP)  = $ 100

              Profit percent =  8%

       Profit = 8% * 100 = [tex]\frac{8}{100}*100 = 8[/tex]

Profit for one racket =$8

Profit for 20 rackets = 8*20 = $ 160

Bags:

CP = $ 80

Loss percent = 15%

[tex]Loss = \frac{15}{100}*80=12[/tex]

Loss for 10 bags = 12 * 10 = $ 120

The profit in the combined transaction = 160 - 120 = $ 40

Answers

Answer: Ello mate, so since there are 5 bags and each weigh 1/2 a pound, 2 bags = 1 pound, right? And since we have 5 bags, 4 bags already equal 2 pounds so that leaves us with 1 bag left over which equals 1/2 a pound, so Tim has 2 1/2 pounds of grapes. Let me know if this helped!

For tropical fish, aquarium water should be set to 76° F with an allowance of 4°.

a. Explain how to write an absolute value equation to represent this situation.

b. Explain the steps to solve the absolute value equation. What do the solutions represent?

Answers

Using absolute value, it is found that:

The absolute value equation that models the situation is: [tex]|T - 76| = 4[/tex]The two solutions, [tex]T = 72[/tex] and [tex]T = 80[/tex], mean that the temperature of the aquarium water must be between these two values.

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

The absolute value function is defined by:

[tex]|x| = x, x \geq 0[/tex]

[tex]|x| = -x, x < 0[/tex]

It measures the distance of a point x to the origin.

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

Item a:

The temperature should be set to 76ºF with an allowance of 4ºF, thus, the absolute value of the difference between the temperature T and 76 should be 4, that is:

[tex]|T - 76| = 4[/tex]

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

Item b:

Here, it is needed to solve the equation.

There are two solutions:

[tex]T - 76 = 4[/tex]

[tex]T = 80[/tex]

Or also:

[tex]T - 76 = -4[/tex]

[tex]T = 72[/tex]

The two solutions, [tex]T = 72[/tex] and [tex]T = 80[/tex], mean that the temperature of the aquarium water must be between these two values.

The perimeter of a rectangular tray is 28 inches. The length of the tray is 2 inches longer the width of the tray. Determine the dimensions of the rectangular tray.

Answers

Step-by-step explanation:

perimeter=28

length=2x

width=x

28=2(x+2x)

28=2x+4x

28=6x

28/6=6x/6

4.67=x

width=4.67

length=2×4.67

=9.34

Using the concept of perimeter of a rectangle, we have that:

The length is of 8 inches.The width is of 6 inches.

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

Perimeter of a rectangle:

The perimeter of a rectangle of length l and width w is given by:

[tex]P = 2(l + w)[/tex]

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

The perimeter is of 28 inches, thus:

[tex]P = 28[/tex]

[tex]2(l + w) = 28[/tex]

Dividing both sides by 2:

[tex]l + w = 14[/tex]

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

The length is 2 inches longer than the width, thus:

[tex]l = 2 + w[/tex]

Replacing into the equation, we find the width:

[tex]2 + w + w = 14[/tex]

[tex]2w = 12[/tex]

[tex]w = \frac{12}{2}[/tex]

[tex]w = 6[/tex]

The width is of 6 inches.

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

The length is:

[tex]l = 2 + w = 2 + 6 = 8[/tex]

The length is of 8 inches.

The sum of three consecutive odd integers is 87. Which equation could you use to find the three
integers and what is the largest integer?
O 3k + 4 = 87
The largest integer is 31
O k + (k + 2) + (k + 4) = 87
The largest integer is 31
O k + (k + 2) + (k + 4) = 87
The largest integer is 29
O k + (k + 1) + (k + 3) = 87
The largest integer is 31

Answers

Answer:

[tex]k+(k+2)+(k+4)=87[/tex]

The largest integer is 31.

Step-by-step explanation:

Hi there!

Let k be equal to the smallest of the integers.

Let (k+2) be the next odd integer.

Let (k+4) be the final odd integer.

We're given that the sum of these three integers is 87. Construct an equation:

[tex]k+(k+2)+(k+4)=87[/tex]

Combine like terms:

[tex]k+k+2+k+4=87\\3k+6=87\\3k=81\\k=27[/tex]

Therefore, the smallest integer is 27. Because the largest integer is k+4, the largest integer is therefore 31.

Given m||n, find the value of x.
t
(7X+7)
(2x+2)

Answers

The value of x is 21.

From the attached diagram we can observe that the lines m and n are parallel to each other and these parallel lines are intersected by transversal t.

Let us assume that angle 'y' be a linear angle with (2x + 2)

(Both angles are below line n)

⇒ y + (2x + 2) = 180°          .............(1)

So that, angles (7x + 7) and angle y are alternate exterior angles.

We know that alternate exterior angles are equal.

⇒ (7x + 7) = y

From equation (1),

(7x + 7) + (2x + 2) = 180°    

9x + 9 = 180

9(x + 1) = 180

x + 1 = 20

x = 21

This is the required value.

Find the complete question below.

Points X, Y, and Z are collinear, with Y in between X and Z. If XY = 5x, YZ = 2x + 7, and XZ = 56, find x.x = 7

Answers

When two or more points are on a straight path, then they are collinear. So that in the given question, the value of x is 7.

Two or more points are said to be collinear if and only if they fall on a straight line. Thus, the points can be joined by a single straight line.

From the given question, it can be observed that;

XZ = XY + YZ

But given the following:

XY = 5x, YZ = 2x + 7, and XZ = 56

Then,

56 = 5x + (2x + 7)

     = 5x + 2x + 7

56 = 7x + 7

collect like terms to have

56 - 7 = 7x

49 = 7x

x = [tex]\frac{49}{7}[/tex]

  = 7

x = 7

Therefore, the value of x is 7.

Help please words about America (ex. democracy,freedom) Read and annotate the article: Weve all created our own personal histories, marked by highs and lows, that we share with the world and we can shape them to live with more meaning and purpose.We are all storytellers all engaged, as the anthropologist Mary Catherine Bateson puts it, in an act of creation of the composition of our lives. Yet unlike most stories weve heard, our lives dont follow a predefined arc. Our identities and experiences are constantly shifting, and storytelling is how we make sense of it. By taking the disparate pieces of our lives and placing them together into a narrative, we create a unified whole that allows us to understand our lives as coherent and coherence, psychologists say, is a key source of meaning.Northwestern University psychologist Dan McAdams is an expert on a concept he calls narrative identity. McAdams describes narrative identity as an internalized story you create about yourself your own personal myth. Like myths, our narrative identity contains heroes and villains that help us or hold us back, major events that determine the plot, challenges overcome and suffering we have endured. When we want people to understand us, we share our story or parts of it with them; when we want to know who another person is, we ask them to share part of their story.An individuals life story is not an exhaustive history of everything that has happened. Rather, we make what McAdams calls narrative choices. Our stories tend to focus on the most extraordinary events, good and bad, because those are the experiences we need to make sense of and that shape us. But our interpretations may differ. For one person, for example, a childhood experience like learning how to swim by being thrown into the water by a parent might explain his sense of himself today as a hardy entrepreneur who learns by taking risks. For another, that experience might explain why he hates boats and does not trust authority figures. A third might leave the experience out of his story altogether, deeming it unimportant.People who believe their lives are meaningful tend to tell stories defined by growth, communion and agency.McAdams has been studying narrative identity for over 30 years. In his interviews, he asks research subjects to divide their lives into chapters and to recount key scenes, such as a high point, a low point, a turning point or an early memory. He encourages participants to think about their personal beliefs and values. Finally, he asks them to reflect on their storys central theme. He has discovered interesting patterns in how people living meaningful lives understand and interpret their experiences. People who are driven to contribute to society and to future generations, he found, are more likely to tell redemptive stories about their lives, or stories that transition from bad to good. There was the man who grew up in dire poverty but told McAdams that his hard circumstances brought him and his family closer together. the rest: 405-588-2610 what is an example of density? pls helppp
