Answer:

Step-by-step explanation:

For the given triangle ABC, the exact values of the three angles are: A = 50°, B = 60°, and C = 70°.

Let ABC be a triangle. The angles A, B, and C can be determined using the fact that the sum of the angles in any triangle is 180°.

We know that

A = 5x, B = 6x, and C = 7x, so:

A + B + C = 5x + 6x + 7x = 18x

Since the sum of the angles in a triangle is 180°, we can set

18x = 180°

and solve for x:

18x = 180°, x = 10°

Therefore, A = 50°, B = 60°, and C = 70°.

Length of the side of square is x = 5.7 unit

The Pythagorean theorem states, "In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides." The sides of this triangle were called the perpendicular, the base and the hypotenuse. Here, the hypotenuse is on the opposite side of the 90° angle, so it is the longest side.

Given,

Figure of a rectangle and a right triangle share its hypotenuse with length of rectangle

diagonal of rectangle = 8

length of both sides of right triangle other than hypotenuse = 4

Let length of rectangle be l

By Pythagoras theorem

l² = 4² + 4²

l² = 32

l = 4√2

Now, In the rectangle

8² = l² + x²

64 = 32 + x²

x² = 32

x = 4√2

x = 5.7

Answer:

[tex]18\frac{1}{24}[/tex] ≅ 18.0416667

Step-by-step explanation:

5 7/8 + 4 1/3 + 7 5/6 = [tex]\frac{433}{24}[/tex]

1.Conversion a mixed number 5 7/8

to an improper fraction: 5 7/8 = 5 7/8

= 5 · 8 + 7/8

= 40 + 7/8

= 47/8

To find a new numerator:

a) Multiply the whole number 5 by the denominator 8. Whole number 5 equally 5 * 8/8 = 40/8

b) Add the answer from the previous step 40 to the numerator 7. New numerator is 40 + 7 = 47

c) Write a previous answer (new numerator 47) over the denominator 8.

Five and seven-eighths is forty-seven eighths.

2. Conversion a mixed number 4 1/3

to an improper fraction: 4 1/3 = 4 1/3 = 4 · 3 + 1/3 = 12 + 1/3 = 13/3

To find a new numerator:

a) Multiply the whole number 4 by the denominator 3. Whole number 4 equally 4 * 3/3 = 12/3

b) Add the answer from the previous step 12 to the numerator 1. New numerator is 12 + 1 = 13

c) Write a previous answer (new numerator 13) over the denominator 3.

Four and one-third are thirteen-thirds.

3. Add: 47/8

+ 13/3

= 47 · 3/8 · 3

+ 13 · 8/3 · 8

= 141/24

+ 104/24

= 141 + 104/24

= 245/24

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - is LCM(8, 3) = 24. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 3 = 24. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - forty-seven eighths plus thirteen-thirds is two hundred forty-five twenty-fourths.

4. Conversion a mixed number 7 5/6

to an improper fraction: 7 5/6 = 7 5/6 = 7 · 6 + 5/6 = 42 + 5/6= 47/6

To find a new numerator:

a) Multiply the whole number 7 by the denominator 6. Whole number 7 equally 7 * 6/6= 42/6

b) Add the answer from the previous step 42 to the numerator 5. New numerator is 42 + 5 = 47

c) Write a previous answer (new numerator 47) over the denominator 6.

Seven and five-sixths are forty-seven-sixths.

5.Add: the result of step No. 3 + 47/6= 245/24 + 47/6 = 245/24 + 47 · 4/6 · 4 = 245/24 + 188/24 = 245 + 188/24 = 433/24

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - is LCM(24, 6) = 24. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 24 × 6 = 144. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - two hundred forty-five twenty-fourths plus forty-seven sixths are four hundred thirty-three twenty-fourths.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Given that, a high school sports team is ordering sports drinks online from a company.

Let the amount of drinks be y and number of drinks be x.

For drink not more than 50.

y=10+0.8x ------(i)

For drinks more than 50

y=15+0.7x ------(ii)

For a purchase of $75, it means that:

y=75

Substitute y=75 in equation (i), we get

y=10+0.8x

75=10+0.8x

0.8x=75-10

0.8x=65

x= 65/0.8

= 81.25

x=81

Substitute y=75 in equation (ii), we get

y=15+0.7x

75=15+0.7x

0.7x=60

x=85.7

x=84

By comparing both values

Answer:

Yes, the segments with lengths 11, 12, and 20 can form a triangle.

To check this, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, we can check that:

11 + 12 > 20

11 + 20 > 12

12 + 20 > 11

Since all three inequalities are satisfied, the segments can form a triangle.

To classify the triangle, we can use the law of cosines, which relates the lengths of the sides of a triangle to the cosine of one of its angles. Specifically, for a triangle with sides a, b, and c and angle A opposite side a, we have:

c^2 = a^2 + b^2 - 2ab cos(A)

Using this formula, we can find the cosine of each angle and determine if the triangle is acute, right, or obtuse based on the values obtained.

For the given triangle, we have:

a = 11, b = 12, c = 20

cos(A) = (b^2 + c^2 - a^2) / (2bc) = (12^2 + 20^2 - 11^2) / (2 * 12 * 20) ≈ 0.714

Since cos(A) is positive and less than 1, the angle A is acute. Similarly, we can find the cosines of the other angles:

cos(B) = (c^2 + a^2 - b^2) / (2ca) ≈ 0.943

cos(C) = (a^2 + b^2 - c^2) / (2ab) ≈ -0.519

Since cos(B) and cos(C) are both positive and less than 1, angles B and C are also acute.

Therefore, the given triangle is acute.

a) Yes, I am skeptical of my friend's claim. The mean score of the class is 80, which means that the average score of all the students is 80.

b) I am also skeptical of my friend's claim that Class 2022 did better than Class 2023 in the Final Test. While the mean score of Class 2022 is higher than the mean score of Class 2023, this does not necessarily mean that Class 2022 did better.

If 50% of the students had a score higher than 80, then the other 50% of the students would have to have a score lower than 80 in order for the mean to be 80. However, my friend's estimation error of 0.07 means that there is a possibility that the true percentage of students with a score higher than 80 is actually between 43% and 57%. Therefore, it is not certain that 50% of the students had a score higher than 80.

It is possible that the distribution of scores for Class 2022 is more spread out, with some students scoring very high and some students scoring very low, while the distribution of scores for Class 2023 is more consistent. Without knowing the standard deviation or the range of the scores for each class, it is not possible to accurately compare the performance of the two classes.

The final answer is 8*2=16 ways

Eight people are to be seated in a row of 8 chairs. In how many ways can these people be seated if two of them insist on sitting next to one another?

There are a couple of steps to solving this problem.

Step 1: Consider the two people who insist on sitting next to one another as one unit. This means that there are now 7 units to be seated in the 8 chairs.

Step 2: Calculate the number of ways that the 7 units can be seated in the 8 chairs. This is done using the formula n!/(n-r)!, where n is the number of chairs and r is the number of units. In this case, n=8 and r=7, so the formula is 8!/(8-7)!, or 8!/1!, which simplifies to 8.

Step 3: Calculate the number of ways that the two people who insist on sitting next to one another can be seated within their unit. There are 2! or 2 ways that they can be seated.

Step 4: Multiply the number of ways that the 7 units can be seated in the 8 chairs by the number of ways that the two people can be seated within their unit. This gives us the total number of ways that the 8 people can be seated if two of them insist on sitting next to one another.

So the final answer is 8*2=16 ways.

The coordinates of B' after the translation represented by (x - 4, y - 3) is (1, -2). See other solutions below

B is located at the point (5, 1) in the figure.

If we translate the point by (x - 4, y - 3), the new location of B, denoted by B', can be found by subtracting 4 from the x-coordinate and 3 from the y-coordinate.

Therefore, B' is located at (1, -2).

The given information provides us with a set of matching points, which are:

Preimage = (2, 1)

Image = (-1, 2)

These points can be represented by the equation:

(x, y) = (-y, x)

This equation indicates that the points have undergone a (d) clockwise rotation of 270 degrees.

Here, the smaller shape is created by scaling down a larger shape, the transformation is a dilation that results in a reduction.

The scale factor for this transformation could be either 1/2 or 1/4.

Given the points P = (3, -2) and S = (4, -5), we apply two transformations.

The first transformation (x - 2, y) is defined as shifting the x-coordinate of each point left by 2 units, while keeping the y-coordinate the same.

This results in new points P' = (1, -2) and S' = (2, -5).

The second transformation involves reflecting the new points across the x-axis, which changes the sign of their y-coordinates.

The resulting points are P'' = (1, 2) and S'' = (2, 5).

In this context, we are given the coordinates of point A as (-2, -5).

This implies that if we scale down the original coordinates by a factor of 1/2, we get the new coordinates of point A, which become (-1, -2.5).

Therefore, the coordinates of point A' are (-1, -2.5).

Answer:

To calculate the probability that the winner of the gift certificate bought a printer from Super Electronics, we need to use the total number of customers who participated in the survey as the denominator and the number of customers who bought printers as the numerator.

The total number of customers who participated in the survey is:

Total Customers = Number of Customers who bought Laptops + Number of Customers who bought Desktops + Number of Customers who bought Printers

Total Customers = 88 + 52 + 64

Total Customers = 204

The number of customers who bought printers is 64.

Therefore, the probability that the winner of the gift certificate bought a printer from Super Electronics is:

P(Bought a Printer) = Number of Customers who bought Printers / Total Customers

P(Bought a Printer) = 64 / 204

P(Bought a Printer) = 0.3137 (rounded to 4 decimal places)

So, the probability that the winner of the gift certificate bought a printer from Super Electronics is 0.3137 or approximately 31.37%.

The accumulated value is $A = 5000 \times e^{(0.09 \times 4)} = 7,311.12$.

The accumulated value of an investment of $\$ 5,000$ at 9% compounded continuously for 4 years is $7,311.12.

This can be calculated using the compound interest formula

\(A=P e^{\lambda t}\).

In this equation, A is the accumulated value of the investment, P is the principal investment amount (which is $\$ 5,000$), $\lambda$ is the interest rate per compounding period (which is 0.09) and t is the number of compounding periods (which is 4 years).

Therefore, the accumulated value is $A = 5000 \times e^{(0.09 \times 4)} = 7,311.12$.
