The constant of proportionality between the amount of tomatoes he orders (in pounds), and their cost (in dollars) is: 4 dollars per pound

To solve this problem we must perform the following algebraic operations with the given information

Information about the problem:

pounds , dollars

Calculating the proportion of the amount of tomatoes he orders and their cost we get:

Proportion dollars per pound = Dollars / pound

Proportion dollars per pound = $88/ 22 pounds = 4 $/pound

Proportion dollars per pound = $92/ 23 pounds = 4 $/pound

Proportion dollars per pound = $96/ 24 pounds = 4 $/pound

Proportion dollars per pound = $100/ 25pounds = 4 $/pound

As we could get the constant of proportionality is 4 $/pound

Answer:

23

Step-by-step explanation:

f(3) = f(2) + f(1) = 5 + 4 = 9

f(4) = f(3) + f(2) = 9 + 5 = 14

f(5) = f(4) + f(3) = 14 + 9 = 23

Answer:

substituting n by 5 gives;

f(5)=(5-1)+(5-2)=7

The probability of winning the game is 1/11.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood of a particular event happening.

Given:

If we win the first time on the 11th game played.

So, we can consider the total is 11.

So, the  probability of winning the game

= 1/11

Hence, the probability of winning the game is 1/11.

Hence when ΔCDE is translated to ΔC'D'E', the congruency is correct  ΔDCE ≅ ΔD'C'E'

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,

CD ≅ C'D'

CE ≅ C'E'

DE ≅ D'E'

Hence, Option (B) is correct answer.

The expression when factorized is (5x + 1)(x + 1)(x - 3)

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)

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.

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.

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
