Find the value of x:a) 2+3−6=−5b) 2(2+1)=5−1

Answers

Answer 1

In order to find the value of x in the expression, we need to isolate the terms with the variable 'x' in one side of the equation, and the variables without 'x' in the other side.

Then, we divide the whole equation by the number multiplying 'x', so we have just 'x' in one side of the equation.

So we have that:

a)

[tex]\begin{gathered} 2+3x-6x=-5x \\ 3x-6x+5x=-2 \\ 2x=-2 \\ x=\frac{-2}{2}=-1 \end{gathered}[/tex]

So the value of x is -1.

b)

[tex]\begin{gathered} 2\left(2+1\right)=5-1 \\ 4x+2=5x-1 \\ 4x-5x=-1-2 \\ -x=-3 \\ x=3 \end{gathered}[/tex]

So the value of x is 3

The length of the base of an isosceles triangle is 49.96 meters. Each base angle is 31.43°. Find the length of each of the two equal sides of the triangle. Round to the hundredths place.

Answers

Given that:

- The triangle is isosceles.

- Its base is 49.96 meters.

- Each base angle is 31.43°.

You can draw the triangle. See the picture shown below (it is not drawn the scale):

Notice that the Isosceles Triangle can be divided into two equal Right Triangles. Then, you know that:

[tex]CD=BD=\frac{49.96m}{2}=24.98m[/tex]

Since it is isosceles, the sides AB and AC have equal length.

Then, you can choose one of the equal Right Triangles and use the following Trigonometric Function in order to find the length of each equal side:

[tex]\cos \beta=\frac{adjacent}{hypotenuse}[/tex]

In this case, you can set up that:

[tex]\begin{gathered} \beta=31.43\degree \\ adjacent=24.98 \\ hypotenuse=AC \end{gathered}[/tex]

Therefore, substituting values and solving for AC, you get:

[tex]\begin{gathered} \cos (31.43\degree)=\frac{24.98}{AC} \\ \\ AC\cdot\cos (31.43\degree)=24.98 \end{gathered}[/tex][tex]\begin{gathered} AC=\frac{24.98}{\cos (31.43\degree)} \\ \\ AC\approx29.28 \end{gathered}[/tex]

Hence, the answer is:

The length of the two equal sides of the triangle is:

[tex]length\approx29.28m[/tex]

About Percentage

The Latin adverb "percent" means "by the hundred." The 16th century saw its invention. The abbreviation was later changed to %. Later, the period was eliminated, and the two words were merged to form the term "percent." Brief explanations employ the annotation sign %. Calculate your percentage of marks by comparing your final score to your overall score.

The percentage is a fraction or a ratio in which the value of the whole is always 100. For example, if Sam scored 30% marks in his math test, it means that he scored 30 marks out of 100. It is written as 30/100 in the fraction form and 30:100 in terms of ratio.

Percentage  Definition:

The percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

At preseident Obama's inauguration in 2013 the newspaper head lines stated there were about 800.000 people in attendance if the newspaper rounded to the nearest hundred thousand what is the largest number and smallest number of people who could have been there

Answers

The smallest whole number is 750,000, while the largest whole number is 849,999.

Consider the facts offered.

We must determine the smallest whole integer that, when rounded to the nearest hundred thousands, equals 800,000

Rounding a numerical rule

If the number on the right side of the rounding digit is 0, 1, 2, 3, 4, there is no need to modify the rounding digit and replace the remainder of the digit on the right with 0.

If the number on the right side of the rounding digit is 5, 6, 7, 8, 9, the rounding digit rounds up by one number and replaces the remainder of the digit on the right with 0.

Consider the number 800,000 for a moment.

Because we want the smallest number possible, the number at the hundred thousand place should be 7.

As a result, the smallest whole number is 750,000.

We now want the largest whole number that rounds to 800,000

Similarly, the biggest whole number must be bigger than 800,000 We don't want to raise the number at the hundred thousand place, hence the best ten thousand place option is 4. Put 9 at the rest locations to get the highest number.

As a result, the biggest whole number is 849,999.

The determinant of the matrix for the pineapple cake is 4350

The price of a pineapple cake is $30

The determinant of the matrix for the chocolate cake is 5075

The price of a chocolate cake is $35

Basically, what we want to do in this question is to form a set of linear equations then use matrix determinant method to solve for the unknowns in the linear equation.

Before we set up these equations,we need to use variables to represent the fruit prices;

Let p represent the price a of pineapple

Let c represent the price of a chocolate;

So let us proceed to form the linear equations;

The equation for the weekdays sales will be;

[tex]45p\text{ + 62c = 3520}[/tex]

The equation for the weekend sales will be;

[tex]55p\text{ + 79c = }4415[/tex]

Now, we have two equations that we need to use the matrix determinant method to solve;

[tex]\begin{bmatrix}{45} & {62} \\ {55} & {79} \\ {} & {}\end{bmatrix}\text{ }\begin{bmatrix}{p} & \\ {c} & {} \\ {} & \end{bmatrix}\text{ = }\begin{bmatrix}{3520} & {} & \\ {4415} & {} & \\ {} & {} & \end{bmatrix}[/tex]

The above is the matrix set up we wil use;

Now, we start by calculating the determinant of 2 * 2 matrix; that would be;

[tex]\begin{gathered} \Delta\text{ = (45 }\times\text{ 79) - (62 }\times\text{ 55)} \\ \Delta\text{ = 3555-3410 = 145} \end{gathered}[/tex]

Next is to find the determinant of the pineapple cake matrix;

To find this, what we will do is to substitute the coefficient of p with the total sales value to get a new matrix set;

The matrix for the pineapple cake will be;

[tex]\begin{gathered} \begin{bmatrix}{3520} & {62} \\ {4415} & {79} \\ {} & {}\end{bmatrix}\text{ } \\ \\ \text{The }\det er\min ant\text{ here will be ;} \\ \Delta_{p\text{ = }}(3520\text{ }\times\text{ 79) - (62 }\times\text{ 4415)} \\ =\text{ 4350} \end{gathered}[/tex]

Next is to find the determinant of the chocolate cake matrix;

To find this, what we will do is to substitute the coefficient of c with the total sales value to get a new matrix set;

The matrix for the chocolate cake will be;

[tex]\begin{gathered} \begin{bmatrix}{45} & {3520} \\ {55} & {4415} \\ {} & {}\end{bmatrix} \\ \\ \Delta_c\text{ = (45 }\times\text{ 4415) - (55 }\times\text{ 3520)} \\ =\text{ 5075} \end{gathered}[/tex]

Finally, we proceed to get the prices for the pineapple and the cake;

To get this, we simply divide the matrix of each by the initial matrix value;

[tex]\begin{gathered} p\text{ = }\frac{\Delta_p}{\Delta}=\frac{4350}{145}=30_{} \\ \\ c\text{ = }\frac{\Delta_c}{\Delta}\text{ = }\frac{5075}{145}\text{ = 35} \end{gathered}[/tex]

Solve by graphing. If the population of a town is growing at a rate of 2.5% each year and the current population is 50,000. After how many years will the population reach 100,000 people. Round to the NEAREST whole number. Be sure to label your answer.

Answers

The situation describes an exponential growth, which can be expressed using the general formula:

[tex]y=a(1+r)^x[/tex]

Where

a is the initial value

r is the growth rate, expressed as a decimal value

x is the number of times intervals

y is the final value after x time intervals

For the studied population, the growth rate is 2.5%, to express this number as a decimal value you have to divide it by 100:

[tex]\begin{gathered} r=\frac{2.5}{100} \\ r=0.025 \end{gathered}[/tex]

The initial value is the current population of the town: a=50000

You can express the equation of exponential growth for this population as follows:

[tex]\begin{gathered} y=50000(1+0.025)^x \\ y=50000(1.025)^x \end{gathered}[/tex]

We know that after x years the population will be y=100000, to determine how many years it will take to reach this value you have to equal the equation to 100000 and solve for x:

[tex]100000=50000(1.025)^x[/tex]

-Divide both sides of the expression by 50000

[tex]\begin{gathered} \frac{100000}{50000}=\frac{50000(1.025)^x}{50000} \\ 2=(1.025)^x \end{gathered}[/tex]

-Apply logarithm to both sides of the equal sign:

[tex]\begin{gathered} \log (2)=\log (1.025^x) \\ \log (2)=x\cdot\log (1.025) \end{gathered}[/tex]

-Divide both sides by the logarithm of 1.025

[tex]\begin{gathered} \frac{\log(2)}{\log(1.025)}=\frac{x\cdot\log (1.025)}{\log (1.025)} \\ x\approx28.07\approx28 \end{gathered}[/tex]

After approximately 28 years the population of the town will be 100,000.

thus, the adjacent side is:

A square is a quadrilateral with four equal straight sides and four right angles.

In this sense since the diagonals of a square bisect each other and meet at 90° and are congruent, we can conclude it is enough justification to prove that CDEF is a square

What is a fraction?

A fraction, which derives from Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of particular size there are when stated in ordinary English. A common, vulgar, or simple fraction is one that has a non-zero denominator that is displayed below (or after) line on which the numerator is shown. Compound fractions, complicated fractions, and mixed numeral fractions are the examples of uncommon fractions that use numerators and denominators.

The numerator and the denominator of positive common fractions are both natural integers. The denominator shows how many of numerator's equal parts make up a unit or whole, and the numerator reflects the number of equal parts. Since there can never be zero components in a whole, denominator cannot be zero. For instance, numerator 3 in the fraction 3/4 denotes that the fraction is made up of 3 equal parts, while denominator 4 denotes that the fraction is made up of 4 parts altogether.

Let, [tex]\frac{3}{8} x[/tex] animals are dogs,

[tex]\frac{2}{5} * \frac{3}{8}x = \frac{3}{20}x[/tex]

Therefore, [tex]\frac{3}{20}[/tex] of the animals at shelter are dogs that have spots.
