Answer:

7087.8m or 7.09km

Step-by-step explanation:

formula used:

distance = speed * time

total distance = distance1 + distance2

let d1 be distance1, d2 be distance2, s1 be speed1, s2 be speed2, t1 be time1, and t2 e time2:

s1 = 5.8m/s, t1 = 12.9 min or 774 sec, s2 = 6.10m/s, t1 = 7.1 min or 426 second

d1 = s1 * t1

   = 5.8 m/s * 774 s

   = 4489.2 m

d2 = s2 * t2

   = 6.10 m/s * 426 s

   = 2598.6 m

total distance = d1 + d2

                       = 4489.2m + 2598.6m

                       = 7087.8 meter or 7.09 kilometer

Consequently, each variable's value for the parallelogram INDY that's diagonals intersect at P and have values of x = 2/3 and y = 8/9.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign. a formula that expresses the connection between two expressions on either side of a sign.

Here,

If a parallelogram INDY has diagonals that intersects at P, then O bisects ID and YN

Hence IP = PD and NP = YP

IP=3x

DP = 6x - 2

NP = 3y and

YP=7x-2,

Substitute

3x = 6x-2

3x-6x = -2

-3x = -2

x = 2/3

x = 0.67

Also NP = YP

3y = 7x-2

3y = 7(2/3) - 2

3y = 14/3 - 2

3y = 14-6/3

3y = 8/3

9y = 8

y = 8/9

Hence the value of each variable for parallelogram INDY That has diagonals that intersect at P is x = 2/3 and y = 8/9.

The difference between 6 1/2 and 2 11/15 is 4 2/5.

Number is a mathematical object used to count, measure, and label. It is an abstract concept that has been used since ancient times and is an important part of mathematics. Numbers are used to represent quantities, such as distance, time, and money. They can also be used to represent abstract ideas such as order in a sequence or the size of a set. Numbers can be represented in various ways, such as symbols, digits, and words. Numbers are also used in many everyday contexts, such as telephone numbers, dates, and scores.

To calculate the difference, we first need to convert 2 11/15 into an improper fraction. To do so, we multiply the denominator (15) by the whole number (2) and add the numerator (11) to get an improper fraction of 31/15.

Next, we subtract 31/15 from 6 1/2. To do so, we need to convert 6 1/2 into an improper fraction. We multiply the denominator (2) by the whole number (6) and add the numerator (1) to get an improper fraction of 13/2.

We then subtract 31/15 from 13/2 to get 4 2/5. This is the difference between 6 1/2 and 2 11/15, written in simplest form.

Therefore, the answer is 4 2/5.

To find the largest four-digit value of t such that the expression is an integer, we need to set up an equation and solve for t.

Let's denote the given expression as x:

x = √(t - √(t - √(t - √(t - ...)))

To simplify the expression, we notice that the inner square root can be represented by x itself. So we can rewrite the equation as:

x = √(t - x)

Squaring both sides to eliminate the square root:

x^2 = t - x

Rearranging the equation:

x^2 + x - t = 0

To find the largest four-digit value of t, we can iterate through the values of t starting from 9999 and solve the quadratic equation for x. We are looking for a positive integer solution for x. Once we find the largest value of t that satisfies this condition, we have our answer.

By solving the quadratic equation for different values of t, the largest four-digit value of t that satisfies the condition is 9985.

There are 232 bit strings of length eight that do not contain six consecutive 0s.

we can use the principle of inclusion-exclusion. There are 28 total bit strings of length eight (since each digit can be either a 0 or a 1). However, if we simply remove all bit strings that contain six consecutive 0s, we would be overcounting some bit strings that contain multiple blocks of six consecutive 0s. To correct for this, we need to add back in the number of bit strings that contain two blocks of six consecutive 0s, which is 2^2 = 4. However, we have now overcorrected by including some bit strings that contain three blocks of six consecutive 0s. So we need to subtract those, which is 2^1 = 2. Finally, we need to add back in the number of bit strings that contain four blocks of six consecutive 0s, which is 1.

Therefore, the total number of bit strings of length eight that do not contain six consecutive 0s is 28 - 4 + 2 - 1 = 25. Since each digit can be either a 0 or a 1, there are 2^8 = 256 total bit strings of length eight. Therefore, the number of bit strings of length eight that do not contain six consecutive 0s is 232.

there are 232 bit strings of length eight that do not contain six consecutive 0s, and we arrived at this answer by using the principle of inclusion-exclusion to count the number of bit strings that do contain six consecutive 0s and then subtracting from the total number of possible bit strings of length eight.

Consider the following parametric equations:\($$x=t^2-3 t \text { and } y=\sqrt{t} \text { and the } y \text {-axis. }$$\)

The objective is to find area enclosed by the curve using the formula.

The area under the curve is given by parametric equations x=f(t), y=g(t),  and is traversed once as t increases from α to β, then the formula for calculating the area under the curve:

\($$A=\int_\alpha^\beta g(t) f^{\prime}(t) d t$$\)

The minimum distance that Malia needs on her last throw to win the game is less than 2.12 meters.

In this target game, Malia needs to have the lowest mean distance of all throws to win. The mean distance is calculated by adding up all the distances and dividing by the number of throws.

First, we need to calculate the mean distance of Malia's first 7 throws.

Mean distance = (2 + 3 + 4 + 2 + 5 + 3 + 4) / 7 = 3.14

Now, we know that Malia's mean distance must be less than 3.14 to win the game. Let's call the distance of her last throw x.

The mean distance of all 8 throws will be: (2 + 3 + 4 + 2 + 5 + 3 + 4 + x) / 8

To find the minimum distance that Malia needs on her last throw to win the game, we can set up an inequality:

(2 + 3 + 4 + 2 + 5 + 3 + 4 + x) / 8 < 3.14

Multiplying both sides by 8 gives us:

2 + 3 + 4 + 2 + 5 + 3 + 4 + x < 25.12

Simplifying gives us:

x < 25.12 - 23

x < 2.12

Therefore, the minimum distance that Malia needs on her last throw to win the game is less than 2.12 meters.

Step-by-step explanation:

The Law of Cosines can be used to find the third side of a triangle in which two sides and the angle between them are given.

The law of cosines tells us ...

  c² = a² +b² -2ab·cos(C)

Using the given values, we have ...

  c² = 4.2² +4.5² -2(4.2)(4.5)cos(26°)

Simplifying the equation, we get ...

  c² = 37.89 -37.8cos(26°) ≈ 3.91559

  c ≈ 1.979 . . . . km

The width of the strait is about 2.0 km.

The measure of m<QRX and m<QRP are 129 and 51 degrees respectively.

The sum of the interior angle of a triangle is 180 degrees, hence;

m<QPR + m<QRP + M<PQR = 180

Substitute the given parameters

49 + m<QRP + 80 = 180

m<QRP + 129 = 180

m<QRP = 180 - 129

m<QRP = 51 degrees

The sum of interior angle is equal to the exterior

m<QPR +  M<PQR = m<QRX

m<QRX = 49 + 80

m<QRX = 129 degrees

Hence the measure of m<QRX and m<QRP are 129 and 51 degrees respectively.
