Here is the answer

Step-by-step explanation:

To find the perimeter of a triangle, we need to add up the lengths of all three sides. In this case, the sides of the triangle are given by the expressions 3x2 - y2, 4x2 - 7xy + 4y, and -3x + 7xy + 8y2.

To find the perimeter, we can simply add up these three expressions:

Perimeter = 3x2 - y2 + 4x2 - 7xy + 4y - 3x + 7xy + 8y2

= 7x2 - 3xy + 12y

This is the perimeter of the triangle. Note that the perimeter is a scalar quantity, not a vector, so it does not have a direction associated with it.

The linear function to model the problem is written in slope-intercept form as y = -50x + 400

A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b

In the question given, we can model a linear function to represent this.

Let x represent the distance covered.

The function can be written as;

f(x) = -50x + 400

This function represents the distance left till she gets home

Plotting this on a graph, we would have a straight line intercpeting the x-axis at (8, 0) and the y- axis at (0, 400)

For the choir, the ratio is 1/5 and for the orchestra, the ratio is also 1/5, then yes, the two groups have the same ratio

Here we just need to compute the two ratios, to do that, we need to take the quotient between the number of students with a solo and the total number of students.

For the choir, there are 25 students and 5 with a solo, so the ratio is:

5/25 = 1/5

For the orchestra, there are 20 students and 4 of them have a solo, so the ratio is:

4/20 = 1/5

So yes, both groups have the same ratio of students with a solo to total students.

The property of congruence illustrated in the statement is the transitive property.

The transitive property states that if A is congruent to B and B is congruent to C, then A is congruent to C. In other words, if two things are congruent to a third thing, they are also congruent to each other.

In the statement "If AB ≅ DE, EF ≅ DE then AB ≅ EF," AB is congruent to DE, and EF is congruent to DE, so AB must also be congruent to EF according to the transitive property.

The other properties you listed are not applicable in this case. The symmetric property states that if A is congruent to B, then B is congruent to A. The reflexive property states that every object is congruent to itself. And multiplication is not a property of congruence.

Therefore ,the collar remain effective for 26.44 days.

In mathematics, there are numerous ways to use the word "order." It most frequently refers to the quantity of elements in (for example, conjugacy class order, graph order, group order, etc.) or describes the biggest term (for example, curve order, surface order, or polynomial order) that appears in a mathematical object.

Here,

=>Rate of evaporation=k=dr/dt

=> amount still present=R.

Thus ,It's a first order reaction.

So, half life=0.693/k.

20=0.693/k.

=> k=0.0346

Now,

60% of active ingredient has been evaporated.

So, 40% left.

Time taken=T=(2.303/k)log(R/0.4R)

T=(2.303/0.0346)log(5/2)

T=66.56(log5-log2)

T=66.56(0.699-0.301)

T=66.56(0.398)

Step-by-step explanation:

The time which has passed when Tom overtakes Hazel is after Hazel has walked 1 hr 15 minutes and in that time Hazel has walked

1.25 * 4.8

= 6 km.

So, Tom runs 6 km in 10:15 - 9.39 = 36 minutes

In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis) respectively.

In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" is equal to zero (0).

Answer:

transversitile multistelular projection

Answer:

Step-by-step explanation:

The perimeter of triangle ACD that is formed by two right-angle triangles ACB and DCB, approximated to 1 decimal place is: 40.1 cm.

The graph of the equation that is parallel to 4x – 3y = –12 is determined as: A. y = 4/3x - 3/2.

If two lines are parallel to each other, their graph will have the same slope value, m. This means if their equations are expressed as y = mx + b in slope-intercept form, they will both have the same value of m.

Given the equation of a graph as 4x - 3y = -12, rewrite it in slope-intercept form to determine the slope value:

4x - 3y = -12

-3y = -4x - 12

-3y/-3 = -4x/-3 - 12/-3

y = 4/3x + 4

This means the slope, m is 4/3. The slope of the graph that is parallel to it will also have a slope of 4/3.

The slope of y = 4/3x - 3/2 is also 4/3, therefore, the answer is: A. y = 4/3x - 3/2.

Mean is calculated to get an idea of the average of the observations in the data set.

The average value of the observations in a data set is called the mean or average . It is calculated by dividing the sum of observations by the number of observations i.e.

u = (x1 + x2 + x3 + .... + xn)/n

where u is the mean , x1 , x2 ...,  xn are data observations and n is the number of observations.

For example, we have values as 1,2,3,4,5 and we want to calculate the mean . Then it is calculated by

u = (1+2+3+4+5) / 5 = 3.

So, the mean is 3.
