The value of x in the given object is 12.

The given shape is an equilateral triangle. A triangle is a three-sided polygon with three edges and vertices. The sum of angles in a triangle is equal to 180 degrees.

An equilateral triangle is a triangle in which the three angles are equal. This means that each angle in an equilateral triangle measures 60 degrees. Also, in an equilateral triangle the three sides are equal.

Since, all the three sides of an equilateral triangle is equal, the expressions for their sides can be equated to each other to determine the value of x

4x - 10 = 5x - 22

Combine similar terms: 22 - 10 = 5x - 4x

Add similar terms: 12 = x

Answer:

Step-by-step explanation:

Based on this parallel lines cut by a transversal, the true statements include the following:

B. m∠1 + m∠3 = 180 because they form a straight angle.

C. ∠3 ≅ ∠6 because they are alternate interior angles.

D. ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent.

A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees (180°).

In conclusion, ∠1 and ∠6 are supplementary angles because ∠3 is congruent to ∠6 and m∠1 + m∠3 = 180 degrees as shown in the image attached below.

The number of infected people will reach 568 in approximately 4 weeks

Exponential equations are inverse of logarithmic equation and are represented by the equation below:

y = ab^x

where

a is the base value and x is the exponent

Given the equation that shows the number of infected people from an outbreak of the measles as:

y = 4(6)^t

If the number of infected people reach 568, hence;

568 = 4(6)^t

568/4 = 4(6)^t/4

6^t = 568/4

6^t = 142

Take the natural logarithm of both sides

ln(6^t) = ln142

t = ln142/ln6

t = 4.37

Hence the number of infected people will reach 568 in approximately 4 weeks

Max is going to have more money than Shawn at the end of the seven weeks from the calculations

We would first have to define x to be the point where the money that they have would be equal

This is the week that is referred to as x

Sean would have $20 + $2x

Max would have $5x

When both amounts are equal, we would have sean = max

= $20 + $2x = $5x

Take like terms

20 = 5x - 2x

20 = 3x

divide through by 3

x = 20 / 3

= 6.6667

Remember

In 7 weeks sean = 20 + 2x 7 = 34

max = 5 x 7 = 75

Using relations in a right triangle, the missing side lengths are given as follows:

1. D. [tex]x = 7\sqrt{2}, y = 7[/tex]

2. B. [tex]x = 3\sqrt{2}, y = 2[/tex].

3. C. x = 6, y = 3.

4. C. [tex]x = 2\sqrt{5}, y = \frac{2\sqrt{15}}{3}[/tex]

There are three relations in a right triangle, given as follows:

For the first triangle, we have that:

tan(45º) = 7/y

1 = 7/y

y = 7.

Applying the Pythagorean Theorem:

x² = 7² + 7²

x = sqrt(2 x 49)

[tex]x = 7\sqrt{2}[/tex]

Hence the correct option is:

D. [tex]x = 7\sqrt{2}, y = 7[/tex]

For the second triangle, we have that:

tan(45º) = y/3

1 = y/3

y = 3.

Applying the Pythagorean Theorem:

x² = 3² + 3²

x = sqrt(2 x 9)

[tex]x = 3\sqrt{2}[/tex]

Hence the correct option is:

B. [tex]x = 3\sqrt{2}, y = 2[/tex].

For the third triangle, we have that:

[tex]\tan{30^\circ} = \frac{y}{3\sqrt{3}}[/tex]

[tex]\frac{\sqrt{3}}{3} = \frac{y}{3\sqrt{3}}[/tex]

y = 3 x 3/3

y = 3.

Then:

[tex]\sin{30^\circ} = \frac{y}{x}[/tex]

0.5 = 3/x

x = 6.

Hence the correct option is:

C. x = 6, y = 3.

For the fourth triangle, we have that:

[tex]\sin{30^\circ} = \frac{y}{\frac{4\sqrt{15}}{3}}[/tex]

[tex]0.5 = \frac{y}{\frac{4\sqrt{15}}{3}}[/tex]

[tex]y = \frac{2\sqrt{15}}{3}[/tex]

[tex]\cos{30^\circ} = \frac{x}{\frac{4\sqrt{15}}{3}}[/tex]

[tex]\frac{\sqrt{3}}{{2}} = \frac{x}{\frac{4\sqrt{15}}{3}}[/tex]

[tex]x = 2\sqrt{5}[/tex]

Hence the correct option is:

C. [tex]x = 2\sqrt{5}, y = \frac{2\sqrt{15}}{3}[/tex]

According to the solving the angular speed of the wheel in radius per minutes would be:

100.

The correct option is 3.

angular velocity is the rate at which an item rotates or revolves around an axis, or the pace that the angular displacement among two bodies varies. This displacement is shown in the diagram by the angle formed by a line with one body and a line on the opposite body.

Angular velocity is defined as the rate of change of an object's position angle with respect to time, therefore w = theta / t, where w denotes angular velocity, theta denotes position angle, and t denotes time.

The angular speed of a rotating object is a scalar measurement. The angular velocity of a rotating object is measured as a vector. Only the magnitude of angular speed is specified. The magnitude and direction of angular velocity are specified.

Radius of the wheel = 2ft

velocity of the wheel = 200 ft/min

We know that the formula of Angular velocity:

ω = ν/r

ω = output

ν = liner velocity

r = path radius

Substituting the value in the formula:

ω = ν/r

ω = 200/2

The simple interest, in two years at the rate of 1.2% is 880

In this case, we must calculate how much interest 2000 would earn compounded yearly over two years at a rate of 1.2.

I = 880 in interest earned

Annually, the system may be evaluated in terms of simple interest.

A = P(rt) for the first year, where r = 1.2 and t = 1.

Therefore;

A = 2000(1.2×1).

A = 2400.

As a result, the revised Principal amount for the second year is 2400.

As a result, A' = 2400 (1.21).

A' = 2880.

As a result, the sum owing after two years is 2880.

However, because the initial principal is $2,000,

The interest is defined as I = A' - P, or I = 2880 - 2000.

I = 880 as a result of interest.

Simple interest is computed as S.I. = P R T, where P = Principal, R = Annual Rate of Interest in %, and T = Time, commonly expressed as the number of years. The interest rate is expressed as a percentage r% and is written as r/100.

The principle is the money borrowed from the bank or invested at the outset. P represents the principal.

Rate: The rate of interest at which the principle amount is handed to someone for a specific period of time; the rate of interest can be 5%, 10%, or 13%, for example. R represents the interest rate.

Time is the length of time for which the primary amount is supplied to someone. T represents time.

The length of one side of the garage originally is 18.17 feet.

The length of one side of the garage now is 22.25 feet.

The percent increase is 22.4%.

A square is a quadrilateral with four sides of equal length. A square has two diagonals of equal length that intersect at right angles.

Given the area of a square, the length of one side can be determined by calculating the square root of the area.

Area of the square = length²

Length of one side of the square = √area

√330 = 18.17 ft

Area of the garage after it was increased : (1 + percentage increase) x initial area

(1 + 0.5) x 330

1.5 x 330 = 495 feet²

Length of the side of the garage after it is increased = √495 = 22.25 feet

Answer:

m=4/3

Step-by-step explanation:

slope=rise/run or y=mx+b

rise/run=8/6=4/3

a. The slope of the line parallel to y = 3/4x - 1 is: 3/4.

b. The slope of the line perpendicular to  y = 3/4x - 1 is: -4/3.

If two lines are parallel to each other, they will have the same slope value. On the other hand, if the two lines are perpendicular to each other, they will have slopes that are negative reciprocals of each other.

Thus, given the equation, y = 3/4x - 1, the slope of this line is 3/4.

The negative reciprocal of 3/4 is -4/3.

Therefore, we can conclude that:

a. The slope of the line parallel to y = 3/4x - 1 is: 3/4.

Answer:

Step-by-step explanation:

Given a table of supply and demand at each price point, you are asked for the equilibrium price if the demand numbers are decreased by 0.5 million.

The equilibrium price is the price at which the quantity demanded is equal to the quantity supplied.

For the given table, we see that a price of $14 thousands will result in both demand and supply being 2.00 millions per year. That is the equilibrium price before any adjustment to the table is made.

The problem statement is telling you to use a table that has all of the demand values decreased by 0.5 million. That makes the demand column read ...

  2.25, 2.00, 1.75, 1.50, 1.25, 1.00, 0.75

This new column of reduced demand values matches the numbers in the supply column when they are both 1.75 million per year. That match occurs on the line with price $12 thousand.

The new equilibrium price is $12 thousand.
