Sturdy’s paper plates cost $3.12 for 24 plates. Tough’s paper plates cost $4.32 for 32 plates. Which is the better buy?

Answers

Answer:

Sturdy's paper plates

Step-by-step explanation:

Let's see how much 8 plates cost:

Sturdy

24/3=8

$3.12/3= $1.04

Tough

32/4=8

$4.32/4=$1.08

$1.04<$1.08

Because Tough's paper plates costs 4 cents more for 8 plates, Sturdy's paper plates are the better buy.

A punch bowl contained 2 liters of ginger ale, 1 liter of orange juice, and 1 liter of cranberry juice. Select all of the statements that are true. (Choose 2) 2 points The ratio of ginger ale to the entire punch bowl is 1 to 4. The ratio of orange juice to ginger ale is 2 to 1. The ratio of juices to ginger ale is 2 to 2. The ratio of the entire punch bowl to the juices is 2 to 4. The ratio of orange juice to the cranberry juice is 1 to 1.

Answers

Answer:

The ratio of juices to ginger ale is 2 to 2

The ratio of orange juice to the cranberry juice is 1 to 1

Step-by-step explanation:

Ginger ale = 2 liters

Orange juice = 1 liter

Cranberry juice = 1 liter

Total ratio = 2 + 1 + 1 = 4

The ratio of ginger ale to the entire punch bowl is 1 to 4.

Ginger ale : entire punch bowl

= 2 : 4

= 1 : 2

Not true

The ratio of orange juice to ginger ale is 2 to 1.

Orange juice : ginger ale = 1 : 2

Not true

The ratio of juices to ginger ale is 2 to 2.

juices : ginger ale = orange juice + cranberry juice : ginger ale

= 1 + 1 : 2

= 2 : 2

True

The ratio of the entire punch bowl to the juices is 2 to 4.

Entire punch bowl : juices 4 : 2

Not true

The ratio of orange juice to the cranberry juice is 1 to 1.

Orange juice : cranberry juice = 1 : 1

True

Substitution:
X + 2y = 13
-2x - 3y = -18

Answers

Answer:

x = -3

y = 8

Step-by-step explanation:

x + 2y = 13    ------------(I)

    x  = 13 - 2y -----------(II)

-2x - 3y = -18 ----------(III)

Substitute x = 13 - 2y in equation (III)

   -2*(13 - 2y)  - 3y = -18

-2*13 - 2y *(-2) -3y = -18

  -26  + 4y  - 3y    = -18             {Combine like terms}

               -26 + y =  -18     {Add 26 to both sides}

                         y = -18 + 26

                         y = 8

Substitute y = 8 in equation (II)

x = 13 - 2*8

  = 13 - 16

x = -3

x = -3

y = 8

A because the others are fractions and not a whole number

Answer:

the answer is c

Step-by-step explanation:

square root of 36 = 6 = 6 / 1D. 37 / 100 is already a fraction. Hence, the only number that cannot be written as a fraction is the square root of 48. The answer is C: the square root of 48 is an irrational number.

the geometric mean of 2 numbers is 20. one of the numbers 50. what is the other
number?

Answers

Answer:

8

Step-by-step explanation:

Let x = the unknown no.

Then

[tex]\frac{50}{20} = \frac{20}{x}[/tex]

50x = 400

 x = 8

If the geometric mean of two numbers is 20, one number is 50 then the other number is 8

What is geometric mean?

"The geometric mean is the average rate of return of a set of values calculated using the products of the terms."

Formula to calculate geometric mean is

[tex]GM = \sqrt{x_{1}.x_{2} }[/tex]

Here,

GM = 20

[tex]x_{1}=50\\ x_{2} =?[/tex]

Substitute the values in the formula

[tex]20=\sqrt{50.x_{2} }[/tex]

Squaring on both sides

[tex]400=50(x_{2})\\ x_{2} =\frac{400}{50} \\x_{2}=8[/tex]

Hence, the other number is 8.
