Debra makes 26.40 from selling 52.8 ounces of lemonade. Find the unit price in dollars per ounce. If necessary, round your answer to the nearest cent.
The unit price in dollars per ounce is 0.5 dollars per ounce.
According to the question,
We have the following information:
Debra makes 26.40 dollars from selling 52.8 ounces of lemonade.
Now, to convert this into dollars per ounce, we will divide the total amount by the number of ounces of lemonade:
Dollars per ounce = 26.40/52.8
Dollars per ounce of lemonade = 0.5
Now, we can also convert this into cent.
We know that 100 cent make 1 dollar.
So, 0.5 cents will make (0.5*100) cents or in other words, 50 cents.
Now, it will be 50 cents per ounce.
Hence, the units price of lemonade in dollar per ounce is 0.5.

At a local print shop, 20 copies can be made for $8. At this rate, how how many copies could be made for $14?
The number of copies that can be made would be: 35 copies
How to solve for the copies that can be madeWe would have to solve this problem through the use of cross multiplication
such that we have 20 copies = 8 dollars
unknown copies ? = 14 dollars
This can be re written to be arranged in the form
20 = 8 dollars
? = 14 dollars
we would have to cross multiply
14 x 20 = 8 x ?
280 = 8?
divide through by 14
? = 280 / 14
= 20
Hence the copies that would be made is 35 copies for 14 dollars at the local print shop

What is translation of triangle?
Triangle is a shape with three angles, thus when it is translated downward, it returns to its original form.
Triangle will remain unchanged after translation since the length of the sides and the measure of the angles are not altered.
Translation involves moving the same triangle to a new location while maintaining the triangle's angle and side.
therefore,

In the probability distribution table x=76 and p(x) is 0.3.
Here X is a random variable. P(X) is its probabilities corresponding to the different values of X.
now according to the properties of probability theory we know that sum of probabilities is 1.
so here to find the value of the probability of X corresponding to the value 76 we should use the following steps:
sum of given probabilities =(0.4+0.2+0.1) = 0.7required probability = 1 - sum of given probabilities = 1 - 0.7 = 0.3What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of random events. The value is expressed from zero to one. The calculus of probability is introduced in mathematics to predict the probability of events occurring. Probability basically means the degree to which something is likely to happen. It is a basic theory of probability that is also used in probability distribution, where the probability of the result of a random experiment is studied.

1. Jack buys small tins of tomatoes every week. They usually cost 50¢ each. Last week,
however, Jack saw that the shop was selling six large tins of tomatoes plus a bag of
pasta for $7.50. He worked out that the pasta was normally $2. Jack decided that he
could use one large tin of tomatoes instead of two small tins so he bought 18 large tins
of tomatoes together with three bags of pasta.
This week, however, the small tins of tomatoes are on offer at $1.60 for a pack of four.
How much more did Jack pay last week for tinned tomatoes than if he had bought them
this week?
Answer is in what unit?
Jack paid $ 2.10 more than last week for tinned tomatoes.
The answer is in dollars.
Given that:-
Price of small tomato tins = 50 cents
Price of pasta packet = $ 2
Price of large tomato tins = 2*50 cents = $ 1
Total price of 6 large tins and a pasta packet = $ 7.50
Price of 4 small tins of tomatoes this week = $ 1.60
Price paid by Jack last week for 18 large tins and 3 pasta packets = 7.50*3 = $ 22.50
Price of 18 large tins = 22.50 - 2*3 = 22.50 - 6 = $ 16.50
As 18 large tins equals 36 small tins, we can write,
Price Jack would have paid this week = 36*1.60/4 = $ 14.40
The amount Jack paid more for tinned tomatoes = 16.50 - 14.40 = $ 2.10

What is meant by the term reflection?A reflection is the shape's mirror image. The line of reflection is formed when an image reflects through a line. A figure is said to reflect another figure when every point in one figure has been equidistant from every point in another figure. The reflected image should be the same shape and size as the original, but it should face in the opposite direction. Translation can also occur as a result of changes in position.The Y-coordinates of a point remain constant when it is reflected across the Y-axis. However, the X-coordinates are transformed into their inverse signs.
As a result, the Y-axis reflection of a point (x, y) is (-x, y).

that measure 80° and 70°. Hannah says that triangles X and Y are not similar.
Jasmine says they are similar. Who is correct? Explain. HELPPP PLEASE
Answer:
Jasmine is correct. The triangles are similar.
Step-by-step explanation:
Triangle that have the same angle measurements are similar.
The sum of the interior angles of a triangle add up to 180
Triangle x has angles that measure 80 and 30. That totals 110. The third angle must be 70 so that it adds up to 180.
Triangle Y has angels that measure 80 and 70. That adds up to 150, that means that its third angles must be 30
Both triangles have angle measurements to 80, 70, and 30 so they are similar.

How to factorize this?
[tex]5x {}^{3} - 9x { }^{2} - 17x - 3[/tex]
The expression when factorized is (5x + 1)(x + 1)(x - 3)
How to factorize the expression?From the question, the expression is given as
5x³ - 9x² - 17x - 3
Express 9x² as 5x² - 15x² + x²
So, we have
5x³ - 9x² - 17x - 3 = 5x³ + 5x² - 15x² + x² - 17x - 3
Express -17x as x - 3x - 15x
So, we have
5x³ - 9x² - 17x - 3 = 5x³ + 5x² - 15x² + x² + x - 3x - 15x - 3
Rearrange the terms
5x³ - 9x² - 17x - 3 = 5x³ + 5x² - 15x² - 15x + x² + x - 3x - 15x - 3
Group the terms in 4's
5x³ - 9x² - 17x - 3 = (5x³ + 5x² - 15x² - 15x) + (x² + x - 3x - 15x - 3)
Factorize each group
5x³ - 9x² - 17x - 3 = 5x(x² + x - 3x - 3) + 1(x² + x - 3x - 3)
So, we have
5x³ - 9x² - 17x - 3 = (5x + 1)(x² + x - 3x - 3)
Factorize x² + x - 3x - 3
5x³ - 9x² - 17x - 3 = (5x + 1)(x(x - 3) + 1(x - 3))
So, we have
5x³ - 9x² - 17x - 3 = (5x + 1)(x + 1)(x - 3)
Hence, the factorized expression is (5x + 1)(x + 1)(x - 3)
