solve the following equation for d. 4hd=3f-g3

Complementary Angles- When the sum of two angles is equal to 90 degrees, they are called complementary angles. (For example, 30 degrees and 60 degrees are complementary angles)

Supplementary Angles-Supplementary angles are those angles that sum up to 180 degrees. (For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°.)

Congruence Postulate- to be congruent if two angles and the side between these two angles of one triangle are congruent to corresponding angles and the included side (side between two angles) of the other triangle

Linear Pairs of Angles-A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

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).

The median is 16.

A stem-and-leaf plot is a table that is similar to a histogram. A stem-and-leaf plot divides a number into a stem and a leaf. The stem is the first number in the digit while the leaf is the last number. For example in the number 21, 2 would be the stem and 1 would be the leaf.

Median can be described as the number that occurs in the middle of a data set that is arranged either in ascending or descending order.

The median of 21 numbers would be the 11th number. The 11th number is 16.

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

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 garden store was able to sell a total of 1,960 bags of potting soil on Saturday and Sunday.

What is distributive property of multiplication over addition ?

If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.

In order to find the number of bags of potting soil sold over those two days, the first step is find out the number of pallets store sold there potting soil :

= 17( on Saturday) + 23 (Sunday)

= 40 palettes

Each palettes has 7 flats so the total number of flats sold is:

= 40 x 7

= 280 flats

Each flat then contains 7 bags so the total number of bags sold is:

= Number of flats sold x 7

= 280 x 7

= 1960 bags

In conclusion 1,960 bags of potting soil were sold.

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:

Answer:

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

It will cost $350.00 to buy enough carpet for the living room.

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

Someone who is earning $39,000 a year, would pay $1,638 towards social security out of their gross wages

Employees in 2012 paid 4.2% of their gross wages towards social security tax.

As the gross yearly wages of an employee is $39,000 and he have to pay the 4.2% of his gross wages towards social security or FICA tax.

Percentage means division by 100 and to know the contribution of the employee we need to multiply the percentage with the gross wages of the employee

He paid towards social security = 4.2% of 39000

The average rate of change in the fuel economy in the interval of speed [60,80] is 0.1

The given function F(x) = −0.005x 2 + 0.8x + 12 models the relationship between a certain vehicle’s speed and the fuel economy

where F(x)= fuel economy in kmpl

               x =speed of the vehicle in km/h

we need  to find  the average rate of change in the fuel economy in the interval of speed [60,80].

At speed 60 km/h

the fuel economy = - 0.005(60²) + 0.8(60) +12

                                      = - 18 + 48 + 12

                                      = 42 kmpl

At speed 80 km/h

the fuel economy = - 0.005(80²) + 0.8(80) +12

                                      = - 32 + 64 + 12

                                      = 44 kmpl

the average rate of change is given by the formula = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

By substituting the values we get= [tex]\frac{44- 42}{80-60}[/tex]

                                                   = 2/ 20

                                                   = 0.1
