What is the unit rate of a 1.25L Coca Cola that cost $1.29
Artyom0805 [142]

a 1.25L Coca Cola that cost $1.29

Unit rate means we need to find the rate of 1 liter of Coca Cola

1.25 L Coca Cola =  $1.29

1 L of Coca Cola = ?

To find 1 liter of Coca cola divide the cost by liter, so we divide 1.29 by 1.25

\frac{1.29}{1.25}

1.032

So the cost of 1 liter of Coco Cola = $1.032

Find: (4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y) Place the correct coefficients in the difference.
DanielleElmas [232]

Answer: Our required answer will be

11x^2y^3-4xy^2

Step-by-step explanation:

Since we have given that

(4x^y^3+2xy^2-2y)-(-7x^2y^3+6xy^2-2y)

We need to get the difference:

1) We first open the second bracket and make appropriate change in signs :

4x^y^3+2xy^2-2y+7x^2y^3-6xy^2+2y

2) Gather the like terms together :

4x^2y^3+2xy^2-2y+7x^2y^3-6xy^2+2y\\\\=4x^2y^3+7x^2y^3+2xy^2-6xy^2-2y+2y\\\\=11x^2y^3-4xy^2

Hence, our required answer will be

11x^2y^3-4xy^2

Order from least to greatest. 10/8, 1.2, 0.556, 0.8%
Vsevolod [243]

The order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>

<h3>Ordering of numbers</h3>

In order to order the given numbers, we will first have to write them as a percentage as shown.

Given the number below

10/8, 1.2, 0.556, 0.8%

Convert to percentage

10/8 = 125%

1.2 = 120%

0.556 = 55.6%

0.8%

Hence the order from least to greatest is 0<u>.8%, 0.556, 1.2 and 10/8</u>
