Total number of working days in school was 212 in a year. Akhilesh was absent for 50 days. Find his attendance percent for the year

Answer:

x = 150 , y = 30 , z = 60

Step-by-step explanation:

x and 30° are same- side interior angles and sum to 180° , that is

x + 30 = 180 ( subtract 30 from both sides )

x = 150

-------------

x and y are a linear pair and sum to 180° , that is

x + y = 180

150 + y = 180 ( subtract 150 from both sides )

y = 30

----------------

since EF and EG are congruent then Δ EFG is isosceles with base angles congruent , then

2 = y = 30

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

z is an exterior angle of Δ EFG , then

z = ∠ 2 + ∠ y = 30 + 30 = 60

The smallest positive debt that can be paid off using sticker trading is $7$ dollars.

To find the smallest positive debt that can be paid off using sticker trading, we need to consider the values of the stickers (in dollars) and find the smallest positive amount that can be reached through a combination of these values.

Given that a Harry Potter sticker is worth $49 and a Twilight sticker is worth $35, we can approach this problem using the concept of the greatest common divisor (GCD) of these two values.

The GCD of $49$ and $35$ is $7$. This means that any multiple of the GCD can be represented using these sticker values.

In other words, any positive multiple of $7$ dollars can be paid off using sticker trading.

Therefore, the smallest positive debt that can be paid off using sticker trading is $7$ dollars.

If two different signs are multiplied, the product obtained should be multiplied by another negative sign. We would then get the last sign as positive.

When two different signs are multiplied, the product obtained should be multiplied by another negative sign. When two different signs are multiplied, we obtain either a positive or negative product depending on the signs. If both signs are positive, the product is positive. If both signs are negative, the product is also positive.

However, if two different signs are multiplied, the product is negative. This is the first step in answering the question.

After we obtain a negative product by multiplying two different signs, we are to multiply this product with another negative sign. Multiplying a negative product with another negative sign would yield a positive result. This is because the product of two negatives is positive.

To understand this concept, we can use numbers as examples. Let us say we want to multiply -5 and 7. The product of -5 and 7 is -35 since we are multiplying two different signs.

The y-intercept of line ↔AB is 56/5.

The equation of line ↔CD is y = (-7/5)x + 12.

To find the y-intercept of line ↔AB, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

Given the coordinates of point A (8, 0) and point B (3, 7), we can calculate the slope of line ↔AB:

slope (m) = (y₂ - y₁) / (x₂ - x₁)

= (7 - 0) / (3 - 8)

= 7 / -5

= -7/5

Now, we can substitute the slope (-7/5) and the coordinates of point A (8, 0) into the slope-intercept form to find the y-intercept:

0 = (-7/5)(8) + b

Simplifying:

0 = -56/5 + b

To isolate b, we can add 56/5 to both sides:

b = 56/5

Therefore, the y-intercept of line ↔AB is 56/5.

Moving on to line ↔CD, given the coordinates of point D (5, 5), we can use the point-slope form of a linear equation to find the equation of the line:

y - y₁ = m(x - x₁)

Substituting the coordinates of point D (5, 5) and the slope from the previous calculation (-7/5), we have:

y - 5 = (-7/5)(x - 5)

Expanding and simplifying:

y - 5 = (-7/5)x + 7

Rearranging the equation to slope-intercept form:

y = (-7/5)x + 7 + 5

y = (-7/5)x + 12

Therefore, the equation of line ↔CD is y = (-7/5)x + 12.

The total distance of the obstacle course can be calculated by finding the distance between each pair of consecutive points and adding them up. The distance between two points (x1, y1) and (x2, y2) can be calculated using the formula: distance = sqrt((x2 - x1)^2 + (y2 - y1)^2).

Using this formula, we can calculate the distances between each pair of consecutive points as follows:

Start to Tire Race: distance = sqrt((-40 - (-40))^2 + (-30 - (-10))^2) = 20 yards

Tire Race to Rope Climb: distance = sqrt((40 - (-40))^2 + (-30 - (-30))^2) = 80 yards

Rope Climb to Monkey Bars: distance = sqrt((40 - 40)^2 + (20 - (-30))^2) = 50 yards

Monkey Bars to Finish: distance = sqrt((10 - 40)^2 + (20 - 20)^2) = 30 yards

Adding up all these distances, we get a total distance of 20 + 80 + 50 + 30 = 180 yards for the obstacle course.

The distance along the ground between the building and the pilot is approximately 92.19 feet (rounded to the nearest tenth).

To find the distance along the ground between the building and the pilot, we can use trigonometry.

We have the following information:

Angle of elevation (θ) = 38°

Distance from the building to the pilot (opposite side) = 72 ft

We need to find the adjacent side, which represents the distance along the ground.

Using the trigonometric function tangent (tan), we can set up the following equation:

tan(θ) = opposite/adjacent

tan(38°) = 72/adjacent

To find the adjacent side, we rearrange the equation:

adjacent = 72 / tan(38°)

Using a calculator, we can evaluate this expression:

adjacent ≈ 72 / 0.7813 ≈ 92.19 ft

Therefore, the distance along the ground between the building and the pilot is approximately 92.19 feet (rounded to the nearest tenth).

The value of x is 70 degrees.

To find the value of x, we can use the properties of angles in a circle.

In the given circle, we have a diameter AB passing through the center of the circle, labeled as point C. Point D is located at 2 o'clock, point B at 3 o'clock, and point A at 9 o'clock.

We are given that angle ABD is labeled as 70 degrees. Since angle ABD is an angle formed by a chord (AB) and a tangent (BD), we can apply the property that the measure of an angle formed by a tangent and a chord is equal to half the measure of the intercepted arc.

In this case, angle ABD intercepts the arc AB. Since AB is a diameter, it subtends a 180-degree arc. Therefore, the measure of angle ABD is equal to half the measure of the intercepted arc AB, which is 180 degrees divided by 2, resulting in 90 degrees.

Now, let's focus on angle DAB, labeled as x. Since angle DAB and angle ABD are vertical angles (angles formed by the intersection of two lines), they have the same measure. Therefore, x is also equal to 70 degrees.

The initial number of people on the bus was 39.

To find out how many people were on the bus initially, we can work backwards from the given information. If 22 people got off the bus and 17 people remained on the bus, we can assume that the total number of people who got off and those who remained accounts for the entire initial number of people on the bus.

Let's denote the initial number of people on the bus as 'x'. According to the information provided, 22 people got off the bus, so the number of people who remained on the bus is 'x - 22'. We are also given that 17 people remained on the bus, so we can set up the equation:

x - 22 = 17

To solve this equation, we can add 22 to both sides:

The function that is decreasing on the same interval as the given function f(x) is h(x) = 2x^2 + 8x + 3.

To determine if a function is increasing or decreasing, we look at the sign of its derivative. If the derivative is positive, the function is increasing, and if the derivative is negative, the function is decreasing.

Taking the derivative of h(x) with respect to x, we get h'(x) = 4x + 8. To find the interval on which h(x) is decreasing, we need to find the values of x for which h'(x) < 0.

Setting h'(x) < 0, we have 4x + 8 < 0. Solving this inequality, we find x < -2.

Therefore, h(x) is decreasing for x < -2. Since the interval where h(x) is decreasing matches the interval for the given function f(x), we can conclude that h(x) = 2x^2 + 8x + 3 is the function that is decreasing on the same interval as f(x).

Overall, the function h(x) = 2x^2 + 8x + 3 is decreasing on the interval x < -2, which aligns with the interval of the given function f(x).

The exponential equation to model Puerto Rico's population in millions after t years is:

[tex]P(t) = 3.72 \times e^(^-^0^.^1^1^8^t^).[/tex]

To model Puerto Rico's population in millions after t years using an exponential equation, we can use the following formula:

[tex]P(t) = P₀ \times e^(^r^t^),[/tex]

where:

P(t) is the population at time t,

P₀ is the initial population (in 2010),

e is the base of the natural logarithm (approximately 2.71828), and

r is the growth rate.

Given that the population of Puerto Rico in 2010 was approximately 3.72 million people, we can substitute P₀ = 3.72 into the equation.

Now, to determine the growth rate (r), we need to consider the population decrease of 11.8% since 2010. We can convert this percentage into a decimal by dividing it by 100, so 11.8% becomes 0.118.

Since the population decreased, we use a negative growth rate, so r = -0.118.

Therefore, the exponential equation to model Puerto Rico's population in millions after t years is:

[tex]P(t) = 3.72 \times e^(^-^0^.^1^1^8^t^).[/tex]

This equation takes into account the initial population in 2010 and the negative growth rate to project the population in millions for any given year (t) after 2010.

The reflected figure is labeled figure C is B: A is congruent to A, B is congruent to B, C is congruent to C. The correct answer is B: A is congruent to A, B is congruent to B, C is congruent to C.

To explain why figure A is congruent to figure C, we need to understand the transformations that were applied to create each figure.

In the given scenario, figure A was translated 3 units to the right and 2 units up to create figure B. This means that every point in figure A was shifted horizontally by 3 units to the right and vertically by 2 units up to obtain the corresponding points in figure B.

Next, figure B was reflected over the x-axis to create figure C. This reflection flips the figure vertically, so the y-coordinates of each point are negated while the x-coordinates remain the same.

Now, if we compare the coordinates of figure A and figure C, we can see that the x-coordinates of each point in figure C are the same as in figure A, while the y-coordinates are negated. This means that the two figures have the same shape and size, just positioned differently on the coordinate plane.

Therefore, we can conclude that figure A is congruent to figure C because they have the same shape and size, even though they are located in different positions on the coordinate plane.
