Now, According to the question:

A triangular prism is a polyhedron with a triangle for a base, thus it is a three-sided prism. Given that the triangle has three sides and a height of h, the surface area would be A = Ph + ab where P is the perimeter of the triangle.

We have :

A right triangular prism has a triangular base with legs of 5 centimeters and 12 centimeters and a hypotenuse of 13 centimeters.

Now,

Hypotenuse  = 13

a = 5 cm

b = 12 cm

The distribution of the mean, median, and mode values will depend on how skewed the distribution is. As a result, mean or mode may be larger than or less than mode.

correct answer is D.

Different measures of the center in a set of numerical data include mean, median, and mode. They each attempt to condense a dataset into a single number that may be used to represent a "typical" data point.

The "mean" value is obtained by summing all the data points and dividing the result by the total number of data points.

The middle number, or median, is obtained by placing all data points in order and choosing the middle one (or, if there are two middle numbers, the mean of those two figures).

Which of the following graphs represents y, the total distance, in kilometers, the student hiked over both days after hiking for x hours on day two?​

Answers

The slope is 2, which equals the distance travelled each hour. The total distance hiked at the start of the second day is represented by the y-intercept, which is 4, which is also the y-value. intercept's

Explain about the Slope?

We locate the rise/run before calculating the slope. Since the line increases by 2 between each point, the rise is 2. It travels over 1 between the points, hence the run is 1. The slope is now 2/1, or 2.

Given that it is rise/run, this gives us miles/hours, which indicates the number of miles she treks per hour.

The line's crossing of the y-axis is known as the y-intercept. At four, this is.

The fact that the y-value at this time is 4 and the x-value at this point is 0 tells us that she has trekked 4 miles in the 0 hours since the start of the second day, which is the distance she has covered so far.

There is a linear relationship between the variables x and y, but not a proportional relationship.

Answers

Answer:

Slope is 3.5

There is a proportional relationship between the variables x and y

The other statements are false.

The slope is 3.5, not 7

A linear relationship is the same a proportional relationship so statement 4 is always false

The graph does pass through (0, 0)

Step-by-step explanation:

Consider the first 2 pairs of coordinates, (2, 7) and (6, 21);

The increase in x is from 2 to 6, i.e. an addition of 4, the increase in y is from 7 to 21, i.e. an addition of 14;

Now consider the the 2nd and 3rd pairs of coordinates, (6, 21) and (8, 28);

The increase in x is from 6 to 8, i.e. an addition of 2, the increase in y is from 21 to 28, i.e. an addition of 7;

So, with the first 2 pairs of coordinates, an increase of 4 in x resulted in an increase of 14 in y and with the second 2 pairs of coordinates, an increase of 2 in x resulted in an increase of 7 in y, i.e. (+4, +14) and (+2, + 7);

2 × (+2, +7) = (+4, 14)

Or:

(+4, +14) ÷ 2 = (+2, +7)

This means a line from the 1st point to the 2nd point and a line from the 2nd point to the 3rd point will have the same gradient:

To find the slope simple, find the increase in y resulting from an increase of 1 in x, so:

(+2, +7) ÷ 2 = (+1, +3.5)

The gradient (or slope) is 3.5;

If there is a line with a fixed gradient that passes through all the points, then the relationship is proportional, also linear;

This is the case for this question;

If we follow the pattern backwards as well, so the point:

(2, 7) - (+2, +7) = (0,0)

This means (0,0) lies on the line.

(0,0), (2, 7), (4, 14), (6, 21), (8, 28), (10, 35), (12, 42), (14, 49), etc.

All these points would lie on the line, just add 2 to x, add 7 to y;

You would find the same points plus others by the rule, add 1 to x, add 3.5 to y.

. If the string from the kite to his hand is 105 feet long, how many feet is the kite above the ground? Round your answer to the nearest hundredth of a foot if necessary.

Answers

Step-by-step explanation:

this creates a right-angled triangle 2.5 ft above the ground.

the string is the Hypotenuse (the side opposite to the 90° angle). the air distance to the height of the kite is one leg, and the height of the kite minus the 2.5 ft is leg 2.

in the trigonometric triangle the up/down side is sine (multiplied by the Hypotenuse or radius of the circle) of the angle at the center of the circle. and the left/right side is cosine (again multiplied by the Hypotenuse or radius) of the angle.

so, the height of the kite above ground is

Answers

The expression representing the total amount paid by Joshua at the register is 1.007x dollars.

We have,

To represent the total amount that Joshua paid at the register, we need to account for the following steps:

- Applying the 5% discount to the original price x:

Discount = 5% of x = 0.05x

Calculating the price after the discount:

Price after discount = x - Discount = x - 0.05x = 0.95 x

Tax = 6% of the discounted price = 0.06 x (0.95x)

The expression for the total amount that Joshua paid at the register:

Total amount paid

= Price after discount + Tax

= 0.95 x + 0.06 (0.95 * x)

Simplifying the expression:

Total amount paid = 0.95x + 0.057x

Total amount paid = 1.007x

If necessary, round your answer to two decimal places, like this: 42. 53

Answers

The length of side AB rounded to two decimal places is 16.25.

In a right angle triangle, the side on the base of the angle in question is divided by the hypotenuse. In this case, we can use the cosine ratio to find the length of AB.

We are provided with the following information,

C is the right angle, C= 90°

A= 52°

AC = 10. 01

sin 52° = 0. 788

cos 52° = 0. 616

tan 52° = 1. 280

Now,

since angle C is the right angle, AB is the hypotenuse.

Therefore, with respect to Angle A, AC will be the base and BC will be the perpendicular.

We know, cos x= base/hypotenuse

In this case, cos A = AC / AB

cos 52° = 10. 01/ AB

AB = 10. 01 / 0. 616

What are Binary Operations?

Binary operations are the operations which are performed on a specific set.

If the operation is defined on a set X, then binary operation can be defined as,

* : X * X → X.

Addition, subtraction, ... are some of the binary operations.

The given binary operation is defined as,

a * b * c = [tex]a^b-b^c+c^a[/tex]

We have to find the value of 1 * (-1) * 2.

By the definition,

1 * (-1) * 2 = [tex]1^{-1}-(-1)^{2}+2^1[/tex]

              = 1 - 1 + 2

              = 2

Hence the correct option is D.

The estimated mean score is given as follows:

19.12.

How to obtain the mean of a data-set?

The mean of a data-set is obtained as the sum of all observations in the data-set divided by the number of observations.

For each score, we consider it to be the mean of each interval in the frequency table, hence the sum of all scores is given as follows:

4 x 19 + 9 x 14 + 13 x 15 + 18 x 28 + 28 x 10 + 43 x 13 = 1740.

The total number of scores is of:

19 + 14 + 15 + 20 + 10 + 13 = 91.

Hence the mean score is obtained as follows:

1740/91 = 19.12.

Does the point (0, 0) satisfy the equation y = x?

Answers

Answer:

yes

Step-by-step explanation:

when y equals 0, x equals 0 also

y = x will produce a straight line passing through the point of origin (0,0)

(x,y) => (0,0)

Plug in the point into the equation, y=x.

We get,

0=0, which is true.

Thus, the point, (0,0), satisfies the equation, y=x.

Answers

When the line passes through two points as shown, the slope is 11/3.

What is slope?

The slope or gradient of a line in mathematics is a number that describes both the direction and the steepness of the line. The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope is a numerical value that describes the steepness of a line and is typically calculated by dividing the vertical distance by the horizontal distance (rise over run) between two points.

Here,

m=3

m=(y2-y1)/(x2-x1)

3=(y+5)/(-3+(2))

-3=y+5

y=-8

The value of slope is 11/3 when the line is passing through 2 points as given.

2. Amy has a room that is 6 feet by 10 feet. She bought tiles
that are 8 inches by 6 inches. How many tiles will she
need to cover the floor?

Answers

What are units?

A unit can be used for measurement, and is commonly found in mathematics to describe length, size, etc.

Because we are dealing with different units here, we first would need to know how many inches are in one foot.

1 foot = 12 inches

Now that we know how many inches are in a foot, we can convert the length and width of the room from feet to inches.

6 feet = 72 inches

10 feet = 120 inches

Taking these numbers, we now need to figure out the area of the floor.

72 × 120 = 8640

Now, find the area of each tile.

6 × 8 = 48

Taking 8640, we can now divide that by 48 to get the number of tiles needed.

8640 ÷ 48 = 180

Therefore, 180 tiles are needed to cover the floor.
