How do you do number 10? I got it wrong and is the only one I'm stuck on. PLEASE HELP, thanks!​

The number of teaspoons of pepper required for beef is ( 3 / 4).

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that the recipe for beef stew calls for 1/4 teaspoon of pepper for every 3 potatoes the number of teaspoons required for 9 potatoes will be calculated as below:-

3 potatoes = ( 1 / 4 ) teaspoon

1 potato = ( 1 / 12 ) teaspoon

9 potatoes = 9 / 12 teaspoon

9 potatoes = 3 / 4 teaspoon

Therefore, the number of teaspoons of pepper required for beef is ( 3 / 4).

Step-by-step explanation:

If you want the reciprocal you need to change the sign to the opposite and flip the numbers.

The worth of the investment is $1.51 * 10^39

The given parameters are

Principal, P = $500

Rate, r - 4%

Time, t = 7 years

Number of times, n = 12

So, we have:

A(t)=P*e^nt

This gives

A(12) =  500 *e^(12 * 7)

Evaluate

A(12) = 1.51 * 10^39

Hence, the worth of the investment is $1.51 * 10^39

Answer:

The final temperature is 10.1 degrees Fahrenheit

Answer:

13 and 39

Step-by-step explanation:

let the smaller number be n then the larger number is 2n + 13 , so

n + 2n + 13 = 52

3n + 13 = 52 ( subtract 13 from both sides )

3n = 39 ( divide both sides by 3 )

n = 13

2n + 13 = 2(13) + 13 = 26 + 13 = 39

then smaller number is 13 and larger number is 39

The three equivalent ratios to 4/14 are:

Equivalent ratios are ratios having the same proportion to each other when they are put in their simplest forms.

Ratios are how much a variable is in relation to the whole.  Ratios are the same as proportions or portions of the whole variable

Ratios can be shown as decimals, fractions, percentages, or with the ratio sign (:).

For instance, 2/5 = 0.4 or 40%

2/7 = 4/14 (2 x 2/7) or 0.2857

8/28 = 4/14 (4/14 x 2) or 0.2857

6/21 = 4/14 (4/14 ÷ 2 x 3) or 0.2857

3/4 = 0.75

Using the z-distribution, it is found that a sample size of 97 is required.

The confidence interval is as follows:

[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]

The margin of error is given by the following rule:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

For this problem, considering a margin of error of 10, the parameters are given by:

[tex]M = 10, \sigma = 50[/tex]

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

Then we take the margin of error equation and solve for n as follows:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]10 = 1.96\frac{50}{\sqrt{n}}[/tex]

[tex]10\sqrt{n} = 50 \times 1.96[/tex]

[tex]\sqrt{n} = 5 \times 1.96[/tex]

[tex](\sqrt{n})^2 = (5 \times 1.96)^2[/tex]

n = 96.04

Rounding up, as a sample size of 96 results in M > 10, we have that:

A sample size of 97 is required.

Answer:

  C = 16

Step-by-step explanation:

Given point M=2 and J=18 on a number line, you want the coordinate of point C that is 7/8 of the distance from M to J.

The distance from M to J is the difference of their coordinates:

  J -M = 18 -2 = 16

7/8 of that distance is ...

  (7/8)(16) = 7(16/8) = 7(2) = 14

You are being asked for the coordinate of the point that is 14 units from M in the direction of J.

To find the coordinate of C, we add the desired distance to the coordinate of M:

  C = M +14

  C = 2 +14 = 16

The coordinate of point C is 16.

|6w - 18| = 12

You can say:

|6w - 18| = 12

6w - 18 = 12 or 6w - 18 = -12

First let’s solve for: 6w - 18 = 12

6w - 18 = 12

ADD 18 to BOTH SIDES

6w - 18 + 18 = 12 + 18

SIMPLIFY IT!
6w = 12 + 18

6w = 30

DIVIDE 6 to BOTH SIDES

6w/6 = 30/6

SIMPLIFY IT!

w = 30/6

w = 5

Second let’s solve for: 6w - 18 = -12

6w - 18 = -12

ADD 18 to BOTH SIDES

6w - 18 + 18 = -12 + 18

SIMPLIFY IT!

6w = -12 + 18

6w = 6

DIVIDE 6 to BOTH SIDES

6w/6 = 6/6

SIMPLIFY IT!
w = 6/6

w = 1

Therefore, your answer should be:

w = 5 or w = 1

Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of the three-dimensional object.

Now it is given that,

Length of room,l =

Width of room, w =

So, area of the room =  l*w = 7*5

⇒ area of the room = 35 square meter

Since, indigo carpet costs $10.00 per square meter

Thus, total cost to install the carpet =  area of the room*carpet costs

⇒ total cost to install the carpet = 35*10

⇒ total cost to install the carpet = $350

During the experiment the temperature changes slightly. Hence

the percentage increase in the temperature of the mixture is 27.35%.

Given, the temperature of the mixture changes from 12 1/4°F to 15 3/5°F

we are asked to determine the percentage of increase in the temperature of the mixture.

Initial temperature = 12 1/4°F

convert it into proper fraction.

= 48+1/4

= 49/4°F

Final temperature = 15 3/5°F

convert it into proper fraction.

= 75+3/5

= 78/5

Therefore, percentage increase:

= Final temp - Initial temp/Initial temp × 100

% Increase = (78/5 - 49/4)/49/4 × 100

% Increase = (78×4 - 49×5/5×4)/49/4 × 100

% Increase = 312-245/5×49 × 100

as 4 gets cancelled from numerator and denominator.

% Increase = 67×100/249

% Increase = 6700/249

% Increase = 27.346%

we need to round it off to the nearest hundredth.

% Increase = 27.35%

Hence the percentage increase in the temperature is  27.35%.

The amount of times that the the bacterial cell is smaller than the amoeba cell is; 150 times

Laws of indices provide us with rules for simplifying calculations or expressions involving powers of the same base.

We are given;

Length of a bacterial cell = 3 * 10⁻⁶ m

Length of an amoeba cell = 4.5 * 10⁻⁴ m

Thus, to get the amount of times that the bacterial cell is smaller than the amoeba cell, we need to convert the Length of a bacterial cell to have same exponent as that of the Length of an amoeba cell before dividing.

Thus;

Length of a bacterial cell = 3 * 10⁻⁶ m

Length of an amoeba cell = 450 * 10⁻⁶ m
