Hello!

Answer:

[tex]\boxed{b=0}\checkmark[/tex]

The answer should have a positive sign.

Step-by-step explanation:

First, switch sides and group like terms.

4b+6=-b+2+4

Then, add numbers from left/right.

2+4=6

4b+6=-b+6

Subtract by 6 both sides of an equation.

4b+6-6=-b+6-6

Simplify.

4b=-b

Next add b both sides of an equation.

4b+b=-b+b

Simplify.

5b=0

Therefore, you divide by 5 from both sides of an equation.

5b/5=0/5

Finally, you simplify and solve to find that answer is.

0/5=0

b=0 is the correct answer.

Hope this helps!

Have a nice day! :)

Answer:

The answer is 57 degrees Fahrenheit

Step-by-step explanation:

The  temperature in degrees Fahrenheit is 57.2°F

The Fahrenheit temperature scale is used in the United States; the Celsius, or centigrade, scale is employed in most other countries and for scientific purposes worldwide.

The conversion formula for a temperature that is expressed on the Celsius (°C) scale to its Fahrenheit (°F) representation is:

°F = (9/5 × °C) + 32.

Given:

temperature= 14 C

using formula,

F=9/5C+32,

F= 9/5 * 14+32

F= 126/5+32

F= 25.2+32

F= 57.2

Hence, the temperature in degrees Fahrenheit is 57.2°F.

Answer:

128 degrees, so C is again the answer.

Step-by-step explanation:

Since angles 3 and 11 are corresponding(from your previous question), angles 1 and 11 will add up to 180 degrees, since a line is that long. Therefore your answer is 180-(degrees of angle 1)= 180-52= 128

m∠11 = 128°.

A line that cuts three parallel lines forms congruent angles which means they measure the same.

In this problem m∠1 = 52° = m∠4 = m∠5 = m∠8 = m∠9 = m∠12, and  m∠2 = m∠3 = m∠6 = m∠7 = m∠10 = m∠11.

To calculate m∠11, we know that m∠12 = m∠1 = 52°, the sum of the angle of m∠11 and m∠12 is 180°. Then:

m∠11 + m∠12 = 180°, with m∠1 = 52° = m∠12

m∠11 + 52° = 180°

m∠11 = 180° - 52°

m∠11 = 128°

The value of Sin θ for a given circle and given condition is (2√5)/5.

A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed point (the center). Any interval joining a point on the circle to the center is called a radius.

Here, let the horizontal side be x.

         vertical side be y

then as per the given condition

Vertical distance = 2 X horizontal distance

      y = 2x

By Pythagoras Theorem,

      r = [tex]\sqrt{x^2+y^2}[/tex]

      1 = [tex]\sqrt{x^2+(2x)^2}[/tex]

      1 = x² + 4x²

      5x² = 1

       x² = 1/5

      x = 1/√5

then, y = 2/√5

Now, Sin θ = perp. / Hypo.

         Sin θ = y/1

           Sin θ  = 2/√5

or        Sin θ  = (2√5)/5

Thus, the value of Sin θ for a given circle and given condition is (2√5)/5.

Step-by-step explanation:

Answer:

y=1/4 x +11

Step-by-step explanation:

So this is a word problem but it isn't too bad to figure what they want:  They are looking for a line that is perpendicular to y=-4x-6 and goes through (-4,10).

So we are looking for an equation whose slope is the opposite reciprocal of the given equation's slope.

The given equation has a slope of -4

The opposite reciprocal of -4 is 1/4 so that is the slope of our new line.

So we know our equation is in the form of y=1/4 x+b

Now we are given that this line should go through (-4,10) so plug it in to find b.

10=1/4 * (-4)+b

10=-1+b

11=b

So the equation is y=1/4 x+11

Answer: [tex]y=\frac{1}{4}x+11[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

Given the equation of the line [tex]y= -4x - 6[/tex], you can identify that the slope is:

[tex]m=-4[/tex]

By definition, the slopes of perpendicular lines are negative reciprocals, then the slope of equation  of the line that represents the new path which will be built perpendicular to other path, is:

[tex]m=\frac{1}{4}[/tex]

Knowing that the path will intersect at the point (-4 ,10), you  need to substitute the slope and this point into  [tex]y=mx+b[/tex] and solve for "b":

[tex]10=\frac{1}{4}(-4)+b\\\\10+1=b\\\\b=11[/tex]

Therefore, the equation that represents the new path is:

 [tex]y=\frac{1}{4}x+11[/tex]

The sum of the real numbers x and y is 25 and their difference is 13. To find the value of xy, we need to solve a system of equations. The value of xy is 114.

To solve this problem, we need to set up a system of equations based on the given information. Let's denote x and y as the two real numbers. The sum of x and y is 25, so we can write the equation x + y = 25. The difference between x and y is 13, so the equation becomes x - y = 13. To find the value of xy, we need to solve this system of equations.

First, let's add the two equations together. (x + y) + (x - y) = 25 + 13. This simplifies to 2x = 38. Dividing both sides by 2, we find x = 19.

Now, we can substitute the value of x into one of the original equations (x + y = 25) to solve for y. 19 + y = 25. Subtracting 19 from both sides, we get y = 6.

Therefore, the value of xy is 19 * 6 = 114.

The center is (0,0) and the radius is 5.

A pie weighs n pounds.  How much would one serving weigh if the entire pie were to be shared equally among 12 people?

Answer: 14 is 20% of 70

The increase in price of the stock is $37.50. To find the percent increase, divide the increase (37.50) by the original price (12.50) and multiply by 100, giving a percent increase of 300%.

The question requires us to find the percent increase in the price of a stock. First, to find the increase, we subtract the initial price from the final price. We get $50 - $12.50 = $37.50. This is the increase in price. To find the percentage increase, we divide this increase by the initial price and multiply by 100 to convert it into percent. Therefore, the percentage increase = ($37.50 / $12.50) x 100 = 300%. Therefore, there is a 300% increase in the stock price.

Step-by-step explanation:

From the attached picture, you will notice that you can fill in the 4 corners of the hexagon with 4 triangles (i.e shaded areas) to form a rectangle.

Area of each shaded corner (triangle) = [tex]\frac{1}{2}[/tex] x 4 x 2.14 = 4.28 cm²

Area of 4 shaded corners = 4 x 4.28 = 17.12cm²

Area of hexagon

= Area of rectangle - Area of 4 shaded corners

= 74.24 - 17.12

The equation 3 • (10 • 12) = (3 • 10) • 12 is justified by the associative property of multiplication, stating that the grouping of numbers in multiplication does not change the outcome.

The equation 3 • (10 • 12) = (3 • 10) • 12 can be justified using the property of associative property of multiplication. This property states that when three or more numbers are multiplied, the way in which the numbers are grouped does not change the product. In simpler terms, no matter how we place the parentheses in a multiplication equation, the result will always be the same.

For example, let's take three numbers, a, b, and c. The associative property of multiplication tells us that (a • b) • c = a • (b • c). Applying this to the given equation, 3 • (10 • 12) is the same as (3 • 10) • 12 because, according to the property, the grouping of numbers does not affect the outcome. This demonstrates why the original equation holds true.

The game’s expected value of points earned for a turn is 71.

Step-by-step explanation:

Here we know that:

Points     Frequency

50           55

75            32

150          13

Here points earned is a random variable.

We need to find its expected value,

Finding Expected value:

Expected value of a random variable is its mean value. So we will first find the mean value of points earned per turn from the table we are given.

Total number of turns = sum of frequencies

= 55 + 32 + 14 = 100

Total points earned = 50(55) + 75(32) + 150(13)

= 7100

Expected value of points earned for a turn = Mean value of points

= Total points/no. of turns

= 7100/100

= 71
