The number of times the hydrogen ion concentration of Aeen’s drink is the hydrogen ion concentration of Marien’s drink is 4 approx.

The phrase "times bigger" shows this:

If a number 'x' is 't' times bigger than 'y', then that means:

[tex]x = t \times y[/tex]

It is because 'y' had to multiply itself with 't' to get in equal level of 'x'

A solution with 'x' as its pH contains [tex]10^{-x} mol/L[/tex] of hydrogen ions.

For the considered case, we have:

Thus, its hydrogen ion concentration is [tex]10^{-2.7}[/tex] = x (say)

Thus, its hydrogen ion concentration is [tex]10^{-3.3}[/tex] = y (say)

Then, let x is t times bigger than y, then that means:

[tex]x = t\times y\\\\t = \dfrac{x}{y} = \dfrac{10^{-2.7}}{10^{-3.3}} = 10^{-2.7 - (-3.3)} = 10^{-0.6} \approx 4[/tex]

It is because of the property [tex]a^b \times a^c = a^{b+c}[/tex]

Thus, hydrogen ion concentration of Marien's drink is approx 4 times the hydrogen ion concentration of Aeen's drink.

Answer:

X=1, y=6

Step-by-step explanation:

Let's solve your system by substitution.

−8x−2y=−20;x+2y=13

Rewrite equations:

x+2y=13;−8x−2y=−20

Step: Solvex+2y=13for x:

x+2y=13

x+2y+−2y=13+−2y(Add -2y to both sides)

x=−2y+13

Step: Substitute−2y+13forxin−8x−2y=−20:

−8x−2y=−20

−8(−2y+13)−2y=−20

14y−104=−20(Simplify both sides of the equation)

14y−104+104=−20+104(Add 104 to both sides)

14y=84

14y

14

=

84

14

(Divide both sides by 14)

y=6

Step: Substitute6foryinx=−2y+13:

x=−2y+13

x=(−2)(6)+13

x=1(Simplify both sides of the equation)

Answer:

x=1 and y=6

Given:

The function f(x) describes the amount of money, in dollars, the club will earn for wrapping x presents.

[tex]f(x)=3x[/tex]

To find:

The f(658).

Solution:

We have,

[tex]f(x)=3x[/tex]

Substitute x=658 to find the value of f(658).

[tex]f(658)=3(658)[/tex]

[tex]f(658)=1974[/tex]

It means, the club will earn $1974 for wrapping 658 presents.

Therefore, [tex]f(658)=1974[/tex].

Answer:

Y= 200

Step-by-step explanation:

Just divide 30 by 0.15

Hope that helps!

Answer: y = 30/0.15

Step-by-step explanation:

First, convert 15% to a decimal by dividing by 100 to get 0.15. The word "of" in an equation means multiply, so the equation would be y*0.15 = 30. To isolate the variable you're trying to solve for, divide both sides by 0.15. The 0.15 on the left side of the equation cancels out, leaving you with a final equation of y = 30/0.15.

Answer:

emma: 6 toys, sally: 13 toys, james: 23 toys

Step-by-step explanation:

if emma had x toys, sally would have (x-3) toys. and we know that if james had 6 more toys, he would have the same amount as both girls combined. so in this case in terms of x, james would have (x+x-3-6) toys, after simplification we get 2x-9 toys..

since we know that the three of them have 52  nerf toys as total, we can set up the equation:

x= number of toys emma has

2x-9+x+x-3=52  

         4x-12=52

               x=16

emma has 16 toys, and sally has (16-3)=13 toys. finally, james has (2*16-9)=23 toys. 16+13+23=52

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of pineapples = 2

Amount given = £5

Amount returned = £3.60

The cost of the two pineapples.

= 5 - 3.60

= £1.40

The cost of one pineapple.

= 1.40/2

= 140/200

= 14/20

= £0.7

Thus,

The cost of one pineapple is £0.7.

Answer:

254.34 miles²

Step-by-step explanation:

How do we find the area of a circle?

Solving

Therefore, the area is 254.34 miles².

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:

Formula for area of a circle:

πr^2,

where pi is equal to 22/7 or 3.14

and r is the radius that is being squared

Plug in the actual values to this formula to find the area;

a = πr^2

a = 3.14 x 9^2

a = 3.14 x 81

a = 254.34, your answer is 254.34 square miles.

Hey there!

In order to simplify this expression, we need to combine like terms.

Remember, like terms are terms from the same "family". not terms that you like. :)

So, the like terms here are

8x, 3x

and

The probability of the spinner landing only once on yellow in two spins is 0.375. Then the correct option is C.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

The total sample will be

Total sample = 16 {RR, BB, YY, GG, RB, BR, RY, YR, RG, GR, BY, YB, BG, GB, YG, GY}

The probability of the spinner landing only once on yellow in two spins will be

Favorable event = 6 {YR, RY, YG, GY, YB, BY}

Then probability will be

[tex]P = \dfrac{6}{16}\\\\P = 0.375[/tex]
