Rose and her twin brother decided to carry their juice in the lunch bags. Rose choose the tin juice that holds 472ml. Her brother took the bottled juice that contains 1/2 litre. Which of the two had more juice and by how much?

Answers

Answer:

Her brother had more juice by 28 mL

Step-by-step explanation:

Convert the 1/2 liter bottle to mL.

In 1 liter, there are 1000 mL. So, in 1/2 liters, there are 500 mL.

Since Rose's tin juice only holds 472 mL, her brother had more juice.

Find how much more he had by finding the difference:

500 - 472

= 28

So, her brother had more juice by 28 mL

Complete the solution of the equation. Find the
value of y when x equals -8.
4x + 9y = -14

does anyone know what this is?

Answers

Answer:

Y is equal to 2

Step-by-step explanation:

X equals -8

So,

4(-8) + 9y = -14

-32 + 9y = -14

-32 + 32 + 9y = -14 + 32

9y = 18

1/9 × 9y = 18 × 1/9

y = 2

The factored form of (20x² – 12x) + (25x– 15) is (4x+ 5)( 5x- 3).

What is Factorize?

The process of breaking or decomposing an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorisation or factoring.

Given:

(20x² – 12x) + (25x– 15)

or, 4x(5x – 3) + 5(5x – 3)

or, (4x+ 5)( 5x- 3)

Hence, the factored form of (20x² – 12x) + (25x– 15) is (4x+ 5)( 5x- 3).

The total cost of Anfä's trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup:
cleaning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and
value of x, the cost of each cavity filling?

Answers

Answer:

The cost of each cavity filling was $ 134.60.

Step-by-step explanation:

Given that the total cost of Anfa's trip to the dentist was $ 628.35, and she paid a flat fee of $ 89.95 which included the checkup: cleaning and then had 4 cavities filled, each of which cost the same amount, to determine which shows the correct equation and value of x, the cost of each cavity filling, the following calculation must be performed:

(628.35 - 89.95) / 4 = X

538.4 / 4 = X

134.6 = X

Therefore, the cost of each cavity filling was $ 134.60.

x = 3y-2

And solve for y

find the area of 72 by 108 inches in square yards? pls show work

Answers

Step-by-step explanation:

72 times 108 = 7776 sq inches

to convert inches to yds divide by 36

7776/ 36 = 216 sq yds

Answer: 6 yards^2

Step-by-step explanation:

first lets find the area of the space in inches and then convert the total to square yards :)

area = length * width

A = 108 * 72 = 7776 inches^2

now lets convert it

there are 1296 inches in a yard, so we divide 7776 by 1296 to find the number of square yards

7776 / 1296 = 6

so the area of the space is 6 yards^2

Answers

Answer:

[tex]a_{n}[/tex] = 6n + 1

Step-by-step explanation:

This is an arithmetic sequence with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 13 - 6 = 7 and d = 6 , then

[tex]a_{n}[/tex] = 7 + 6(n - 1) = 7 + 6n - 6 = 6n + 1

Answer:

the first few terms would be

7, 13, 19, 25, 31

nth term = 7 + 6(n+1)

nth term = 7+ 6n + 6

nth term = 6n + 13

The area of a rectangular painting is 5049 cm. If the width of the painting is 51 cm, what is its
length?

Answers

Answer:

The length is 99 centimeters.

Step-by-step explanation:

The area of a rectangle is found by multiplying:

A = Length • width

We also know that the area of the rectangular painting is 5,049 cm^2

An equation to represent this is:

51w = 5049

To find w, divide:

5049/51 = 99

CHECK YOUR ANSWER:

Formula tor area of a rectangle:

Length x width

Use formula with the measurements:

99 x 52 = 5049

So the length is 99 centimeters.
