Which of the following is an example of a proportional equation? *

Answer:

Choice A

Step-by-step explanation:

This is just order of operations and spreading out your number outside of the parentheses into the numbers inside of it

a) 7(4x+1)-> 7(4x)+7(1)-> 28x+7  = 28x+7

b) 6(x+2)-> 6(x) +6(2)-> 6x+12 ≠ 8x

c) 4(2x+4)-> 4(2x)+4(4)-> 8x+16 ≠ 8x+10

The question is incomplete, the complete question is;

Based on the information in the table, is the cost of the apples proportional to the weight of apples?

Pound of apples:

2

3

4

5

Cost of apples:

$3.76

$5.64

$7.52

$9.40

2. Based on the information in the table, is the cost of the pizza proportional to the number of toppings?

Number of toppings:

2

3

4

5

Cost of pizza:

$11.99

$13.49

$14.99

$16.49

Answer:

See explanation

Step-by-step explanation:

Based on the information provided, there is a proportional relationship between the cost of the apples and the weight of the apples as well as between the number of toppings and the cost of the pizza.

We know that there is a proportional relationship when there is a linear increase  or decrease in the two quantities in the relationship. This increase or decrease is usually by a constant value.

In the relationship between the weight of apples and the cost of apples, the cost of apples increases steadily by $1.88 which shows a proportional relationship.

Also, in the relationship between the number of toppings and the cost of pizza, the cost of pizza increases by $1.5 which shows a proportional relationship between the two.

Answer:

  32.4 feet

Step-by-step explanation:

The applicable relationship between angle and triangle lengths is ...

  Sin = Opposite/Hypotenuse

The dock height is the side of the triangle opposite the given angle. The desired length is the hypotenuse of the triangle, so we have ...

  sin(18°) = (10 ft)/s

  s = (10 ft)/sin(18°) = (10/0.30902) ft

  s ≈ 32.4 ft

The length of the rope is about 32.4 feet.

Answer:

1579

Step-by-step explanation:

There is a particular formula you must use and it leads to this 420(1 + 0.18)^8=1579

The number of visits when you would receive a discount and a free product at the same time is on the 20th visit.

A multiple of a number is the product of an integer and that number. For example a multiple of 10 is 120. This is because the product of 10 and 12 is 120.

In order to determine the number of visit, the multiple of 4 and 10 has to be determined. The first common multiple is required answer

The first ten multiples of 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40

The first ten multiples of 10 = 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

Answer:

1/10 acres

Step-by-step explanation:

A land developer wants to divide up 9/10 of an acre Of land into equally sized lots for houses. He wants to build nine houses. How big can he make each lot?

This is calculated as:

1 lot = 1 house

Hence:

9 house = 9/10 acres

1 house = x

Cross Multiply

9x = 9/10 acres

x = 9/10 ÷ 9

x = 9/10 × 1/9

x = 1/10 acres

Hence, the size of each lot when divided equally = 1/10 acres

Answer:

20%

Step-by-step explanation:

Here, we want to calculate the percentage increase in the price of a can of green beans

Mathematically, we use the formula below;

(new price - old price)/old price * 100%

From the question;

old price = $0.50

new price = $0.60

So we have;

(0.6-0.5)/0.5 * 100%

= 0.1/0.5 * 100%

= 20%

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A bakery sells 44 large boxes of muffins and 50 small boxes of muffins in one day. Each large box holds 20 muffins, and each small box holds 15 muffins.

The total number of muffins sold on this day will be calculated as,

⇒ 44 x 20 + 50 x 15

⇒ 880 + 750

⇒ 1,630

The total number of muffins sold on this day will be 1,630.

Full question:

A transaction is positive if there is a sale and negative when there is a return. Each time a customer uses credit card for a transaction, the credit company charges Isabel. The credit company charges 1.5% of each sale and a fee of 0.5 % for returns

Let x represent the amount of a transaction and let f(x) represent the amount Isabel is charged for the transaction. Write a function that expresses f(x)

Answer:

f(x)= 0.015(x)

f(x)= 0.005(x)

Explanation:

If Isabel makes a sale, she has a positive transaction and therefore is charged 1.5%(which is 0.015) by the credit company for the transaction. If the product is returned, it is a negative transaction and the credit company charges 0.5%(which is 0.005) for the transaction. The functions for positive and negative transactions would be different as indicated in the answer since transactions( given by x) are different- positive and negative.
