Answer:

okay well all i can explain is the image on the far left, the answer would be x=112 and then for the one on the far right (im not sure ) i think its 17

explanation: so a straight line had 180 degress and the outside angle is 126 meaning that if you do 180-126 you can find the amount of the inside angle on the bottom right. When you do this you get 54 degress. Then remember that a triangle has a total of 180 degrees all added up so the final angle inside the triagle is 80 minus the sum of the other two angles. 58+54=112 and 180-112=68. remember that 68 is the angle on the INSIDE and x is clearly on the outside meaning that you would need to do 180-68. your final answer would be 112. (and im really sorry i couldn't answer the other ones they're too blurry  :(

To find the equation of the line tangent to the curve 2ey = x + y at the point (2, 0), we need to find the derivative of the curve and evaluate it at the given point.

First, we differentiate the equation 2ey = x + y with respect to x using the rules of calculus. Taking the derivative of ey with respect to x gives us ey(dy/dx) = 1 + dy/dx.

Simplifying the equation, we get dy/dx = (1 - ey)/(ey - 1).

Next, we substitute x = 2 and y = 0 into the derivative equation to find the slope of the tangent line at the point (2, 0). Plugging in these values gives us dy/dx = (1 - e0)/(e0 - 1) = 0.

Since the slope of the tangent line is 0, we know that the line is horizontal. Therefore, the equation of the tangent line in slope-intercept form is y = 0x + b, where b is the y-intercept.

Since the tangent line passes through the point (2, 0), we can substitute these coordinates into the equation to solve for the y-intercept. Thus, we have 0 = 0(2) + b, which gives us b = 0.

Therefore, the equation of the tangent line is y = 0x + 0, which simplifies to y = 0.

The total number of tasks Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed

The factor 'x' in the expression '90x - 20' represents the total number of tasks that Terrence completed in the game.

To understand why, let's break down the given information. It states that Shelly and Terrence completed a different number of tasks. Shelly earned 90 points on each task, so the total number of tasks she completed is not represented by 'x'.

On the other hand, Terrence's total points were 20 less than Shelly's total. This means that Terrence's total points can be calculated by subtracting 20 from Shelly's total points. Since Shelly earned 90 points on each task, her total points would be 90 multiplied by the number of tasks she completed.

So, the expression '90x - 20' represents Terrence's total points in the game, where 'x' represents the total number of tasks that Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed, we can calculate his total points.

Therefore, the correct answer is: The total number of tasks Terrence completed.

The nearest thousand to 7412 is 7000.

Answer: 7000

Step-by-step explanation: When you round 7412 to the nearest thousand you should get 7000.

When simplifying the equation 4(x + 2) - x = 2x - (-x - 8), we obtain 8 = 8. This equation simplifies to 8 = 8, which means that both sides of the equation are equal.

This implies that any value of x would satisfy the equation, making it true for all values of x. Therefore, the equation has infinitely many solutions, meaning that any value of x can be substituted into the equation and it will still hold true.

-1(x-5)

Answer:

To solve for the value of a that will make the equation true, we can expand the left side of the equation using the square of a binomial formula:

(x + a)^2 = x^2 + 2ax + a^2

Substituting this expression back into the original equation, we get:

x^2 + 2ax + a^2 = x^2 + 16x + 64

We can then simplify this equation by canceling out the x^2 terms on both sides, which gives:

2ax + a^2 = 16x + 64

Next, we can isolate the variable a on one side of the equation by subtracting 2ax and 64 from both sides:

a^2 - 2ax = 64 - 16x

Finally, we can factor out the variable a from the left side of the equation:

a(a - 2x) = 64 - 16x

To solve for a, we can divide both sides by (a - 2x):

a = (64 - 16x)/(a - 2x)

However, we must also note that the denominator (a - 2x) cannot be zero, as this would result in a division by zero error. Thus, we must ensure that a ≠ 2x.

Therefore, the value of a that will make the equation true is:

a = (64 - 16x)/(a - 2x), where a ≠ 2x.

Step-by-step explanation:

Answer:

B. a=8

Step-by-step explanation:

First, let's look at the expression that is on the right side of the equal sign:

\(x^2+16x+64\)

This expression is equal to:

\((x+a)^2\)

So, it must mean that the expression on the right is merely the expanded form of the expression on the left.

Recall the expanded form for the square of a sum:

\((a+b)^2=a^2+b^2+2ab\)

Notice that 64 is equal to 8 squared, and 16x is equal to 2 times 8 times x.

This must mean that \(a=8\).

Thus, our answer is:

B. a=8

Answer:

You need to put the fractions for us to answer but fractions that are greater than 1/2 include: 3/4 and  4/7  and  basically any fraction that has a value greater than 0.5

Step-by-step explanation:

The number of children that were admitted = 196

The number of adults that were admitted = 160

Given that,

The admission fee at an amusement park for children =  $1.25

The admission fee at an amusement park for adults = $6.80

On a certain day, people entered the park = 356

The admission fees collected totaled = $1333

Let us assume,

The number of children that were admitted represented as = x

The number of adults that were admitted represented as = y

On a certain day, 356 people entered the park.

So,

We can write,

x + y = 356  

x = 356 - y                                    (Equation-1)

The admission fee at the amusement park is $1.25 for children and $6.80 for adults.

The admission fees collected on that day totaled $1333.

Then the,

1.25x + 6.8y = 1333                      (Equation-2)

Substituting x = 356 - y into equation 2, it becomes

1.25x + 6.8y = 1333

1.25(356 - y) + 6.8y = 1333

445 - 1.25y + 6.8y = 1333

-1.25y + 6.8y = 1333 - 445

5.55y = 888

y = 888 / 5.55

y = 160

Then we can substitute y value in equation - 1,

x = 356 - y      

x = 356 - 160

x = 196

Therefore,

The number of children that were admitted = 196

The number of adults that were admitted = 160

The length of the common external tangent is equal to the sum of the radii of circles b and c. Since circle a has a radius of 1, the sum of the radii of circles b and c is equal to the radius of circle d. Therefore, the radius of circle b is \(\frac{2}{3}\)

To find the radius of circle b, let's examine the given information.
We know that circle a has a radius of 1 and passes through the center of circle d.

Since circle b and c are congruent, they have the same radius.
Since circles a, b, and c are externally tangent to each other, their radii form a line that is tangent to circle d.

This line is called a common external tangent.
From the diagram, we can see that the common external tangent is perpendicular to the radius of circle d.

Therefore, the length of the common external tangent is equal to the sum of the radii of circles b and c.
Since circle a has a radius of 1, the sum of the radii of circles b and c is equal to the radius of circle d.

Point A is located at (4, 4) in the coordinate plane.With these dimensions, we can determine that Point A is located at (4, 4) in the coordinate plane.

To find the coordinates of point A, we need to consider the properties of the shaded region. The shaded region consists of a rectangle and a triangle. We know that the area of the shaded region is 120 square units, and the height of the line segment above the horizontal axis is 4 units.

The rectangle's area is given by its length multiplied by its width. Since the height of the rectangle is 4 units, we can deduce that the length of the rectangle is also 4 units. Therefore, the width of the rectangle can be found by dividing the total area of the shaded region by the length of the rectangle.

Subtracting the width of the rectangle from the total width of the shaded region will give us the base of the triangle. Since the triangle is isosceles, the base length is equal to the height of the rectangle.

The margin of error of the given population proportion by applying an estimate of the standard deviation based on the simulation is equal to 0.06.

Sample proportion = 0.18

Number of trials = 100

Sample size = 50

To determine the margin of error for the population proportion using an estimate of the standard deviation,

we can use the range of the sample proportions from the simulation.

The margin of error is calculated as half of the range.

In this case, the minimum sample proportion is 0.28 and the maximum sample proportion is 0.40.

Range = Maximum sample proportion - Minimum sample proportion

Range = 0.40 - 0.28

           = 0.12

The margin of error is half of the range,

Margin of Error = Range / 2

Margin of Error = 0.12 / 2
