What is ratio grade 7?

All of the rectangles together measure 1250 meters in length.

A textile square with a 25 square meter surface area. We are aware that the area of a square is determined by multiplying one side's length by itself. The square root of 25 square meters, or 5 meters, is the length of one side of the square in this instance.

Secondly, we are aware that the fabric is being cut into 50 cm-wide rectangles. We can use the following formula to determine each rectangle's length:

(Rectangle width) x (Square cloth length) / (Width of square cloth)

The equation in this instance is (50 cm) x (25 m) / (5 m) = 2500 cm or 25 meters.

Therefore, each rectangle is 25 meters long.

We divide the square cloth's length by each rectangle's width to get the total number of rectangles.

25m / 0.5m (50cm) = 50 rectangles.

Finally, we multiply the quantity of rectangles by the average length of each rectangle to determine the total length of all the rectangles:

50 m x 25 m = 1250 m

Therefore, a square piece of fabric that is 25 square meters in size and has been divided into 50 rectangles, each measuring 50 cm wide and 25 meters long.

Therefore the rectangles together measure 1250 meters in length.

When Claire and Megan meet, they will be $13\frac{1}{2}$ miles away from the outpost.

Speed is the rate at which an object moves or travels over a period of time. It is measured in units such as meters per second (m/s) or kilometers per hour (km/h). Speed is a scalar quantity, meaning it has only magnitude and not direction. For example, a car travelling at 30 km/h has a speed of 30 km/h regardless of the direction it is travelling.

This is because Claire runs at a faster speed than Megan and will reach the outpost first. When she turns around and runs back, she will have gone $9$ miles, and Megan will have gone $8\frac{1}{2}$ miles. When they meet, they will have gone a total of $17\frac{1}{2}$ miles, leaving them $13\frac{1}{2}$ miles away from the outpost.

As per the given matrix, the stable distribution for the regular stochastic matrix is [tex]\begin{bmatrix}x \\y\end{bmatrix}=\begin{bmatrix}0.40 \\0.10\end{bmatrix}[/tex]

The term matrix is defined as  a set of numbers arranged in rows and columns so as to form a rectangular array.

Here we have given that the matrix is written as

[tex]\begin{bmatrix}0.5 & 0.2 \\0.5 & 0.8\end{bmatrix}[/tex]

In order to find the  stable distribution for the regular stochastic matrix, we must know what does it means in matrix.

The term  stable distribution for the regular stochastic matrix in math is defined as a square matrix whose columns are probability vectors. And the  probability vector is a numerical vector whose entries are real numbers between 0 and 1 whose sum is 1.

Here in order to find the solution, we have to equate the value with x and y and then we have to cross multiply the terms, then we get,

=> [tex]\begin{bmatrix}x \\y\end{bmatrix}=\begin{bmatrix}0.5\times0.8 \\0.2\times0.5\end{bmatrix}[/tex]

When we simplify this we get the solution as,

70 different divisions are possible when eight children are divided into two teams each containing 4 children to play a game against each other

so this is what's known as a combination. a combination is a group where the order does not matter. to solve a combination, you use this equation:

n! / (r! *(n-r)!)

n is the total number of objects being sorted (8)

r is the group you need to sort them into (4)

(i know it's 2 groups of 4 but if you solve this for 1 group, the other group is automatically made of the remaining kids)

definition of !:

a number with a ! means 1*2*3...*that number (so that number multiplied by every number smaller than it all the way to one)

so we put 8 and 4 in this equation:

8! / (4! *(8-4)!)

simplify:

8! / *(4! 4!)

multiply out:

Step-by-step explanation:

The cartesian equation for the curve r = 7 cos(θ) is [x -(7/2)]²+y² = 49/4, which is the equation of a circle.

Given r =7 cosθ

Multiplying throughout by ‘r’,

r² =7r cos θ --- (1)

Consider x² + y² = r² and put x = r cos θ --- (2)

x² + y² = 7x

Using completing the square method:

x² - 7x + (7/2)² + y² = (7/2)²

[x - (7/2)]² + y² = 49/4

(x - 7/2)² + (y - 0)² = (7/2)²

For there to be no real solutions, the discriminant (b^2 - 4ac) must be negative. The discriminant is 5^2 - 4(1)(n) = 25 - 4n. So for there to be no real solutions, 25 - 4n < 0, or n > 6.25.

The maximum area of the rectangle is determined by the distance between the two points on the graph and the -axis.

A rectangle is a four-sided shape with four right angles and two pairs of parallel sides. It is one of the most common shapes in the world, found in everything from building designs to artwork. Rectangles are also used in math, specifically to measure area and perimeter. Rectangles can also be classified according to their sides, with squares being a special type of rectangle with four equal sides.

To calculate the maximum possible area of the rectangle, we can use the formula A = (x2 - x1)(y2 - y1).

In this case, the two points on the graph have the same -coordinate, so the x2 - x1 part of the equation is zero. This means that the y2 - y1 part of the equation gives the maximum possible area of the rectangle. To calculate this, we need to take the difference between the two points on the graph.

For example, if the two points on the graph were (2,4) and (2,6), the maximum area of the rectangle would be (6 - 4) = 2.

Therefore, the maximum possible area of the rectangle is equal to the difference between the two points on the graph.

Step-by-step explanation:

Answer: Let's call the hourly rate of the first mechanic "r1" and the hourly rate of the second mechanic "r2".

We know that the total time they worked is 20 hours + 5 hours = 25 hours.

We also know that the sum of their hourly rates is $95 per hour, so:

r1 + r2 = $95

We can use this information along with the total amount they charged, $1150, to find out how much each mechanic charged. We know that the total amount charged is the product of the number of hours worked and the hourly rate. So we can use the following equation:

(20 hours * r1) + (5 hours * r2) = $1150

Now we can substitute the equation r1 + r2 = $95 into the above equation and solve for r1:

(20 hours * r1) + (5 hours * (95 - r1)) = $1150

20r1 + 475 - 5r1 = 1150

15r1 = 675

r1 = $45/hour

To find out the hourly rate of the second mechanic, we can use the equation r1 + r2 = $95

r2 = $95 - r1

r2 = $95 - $45

r2 = $50/hour

So the first mechanic charges $45 per hour and the second mechanic charges $50 per hour.
