Answer:
21 male students
Step-by-step explanation:
For every teacher on the trip, 3 male students and 5 female students are there
If there are 35 female students, we have to divide that by 5 to find the number of teachers
35 divided by 5 is 7
There are seven teachers, so we multiply by 3 to find the number of male students
7 x 3 = 21

2. How do the sizes of the circles compare?
3. Are triangles ABC and DEF similar? Explain your reasoning.
4. How can you use the coordinates of A to find the coordinates of D?
When the radius of circle 2 is twice the radius of circle 1, the size of circle 2 is larger than circle 1.
What is triangle?In geometry, a triangle is a polygon with three sides and three angles. The sum of the angles in a triangle is always 180 degrees. Triangles are one of the most basic and fundamental shapes in geometry and are used in many mathematical and real-world applications, such as in architecture, engineering, and physics. There are different types of triangles based on the length of their sides and the measures of their angles, such as equilateral triangles, isosceles triangles, scalene triangles, acute triangles, obtuse triangles, and right triangles.
Here,
2. This is because the circumference and area of a circle are directly proportional to the radius.
3. To determine if triangles ABC and DEF are similar, we need to check if their corresponding angles are congruent and if their corresponding sides are in proportion. From the diagram, we can see that angle A is congruent to angle D, angle B is congruent to angle E, and angle C is congruent to angle F. This satisfies the angle-angle (AA) similarity criterion. Additionally, we can use the side-side-side (SSS) similarity criterion to determine if the corresponding sides are in proportion. From the diagram, we can see that side AB is parallel to side DE, side AC is parallel to side DF, and side BC is parallel to side EF. Therefore, we can conclude that triangles ABC and DEF are similar.
4. To find the coordinates of D using the coordinates of A, we need to determine the translation from A to D. From the diagram, we can see that A is translated two units to the right and three units down to get to D. Therefore, we can find the coordinates of D by adding two to the x-coordinate of A and subtracting three from the y-coordinate of A. If the coordinates of A are (x1, y1), then the coordinates of D would be (x1 + 2, y1 - 3).
A= (-0.87,0.5)
D=(-0.87 + 2, 0.5 - 3)
D=(1.13,-2.5)

The bank statement that is shown in the question shows a loss of £285.00 and calculated by subtracting the total expenses (money out) from the total revenue (money in).
Define profit or loss?Profit or loss is a measure of the financial performance of a business, organization, or individual over a given period of time.
Profit refers to the positive difference between the revenue earned by a business or individual and the expenses incurred during a given period.
A loss occurs when the expenses incurred exceed the revenue earned during a given period.
To calculate the profit or loss, you need to subtract the total expenses (money out) from the total revenue (money in).
In this case, the total revenue is £315.00 + £265.00 + £190.00 = £770.00, and the total expenses are £210.00 + £30.00 + £450.00 + £100.00 = £790.00.
So, the calculation would be:
Total revenue - total expenses = profit/loss
£770.00 - £790.00 = -£20.00

The observer deck of a ship is located at the origin of a coordinate system. Find the bearing of an object located at the point (5, 5).
Answer:
The observer deck of a ship is located at the origin of a coordinate system. Find the bearing of an object located at the point (5, 5).
Step-by-step explanation:
To find the bearing of an object located at the point (5, 5) relative to the observer deck at the origin of a coordinate system, we need to find the angle between the positive x-axis and the line connecting the observer deck to the object.
First, we calculate the slope of the line connecting the observer deck at (0, 0) to the object at (5, 5):
slope = (change in y) / (change in x)
= (5 - 0) / (5 - 0)
= 1
Next, we use the inverse tangent function to find the angle whose tangent is equal to the slope:
angle = arctan(slope)
= arctan(1)
= 45°
Therefore, the bearing of the object located at (5, 5) relative to the observer deck at the origin is 45 degrees.
Answer:
45° north of east
Step-by-step explanation:
tan⁻¹(y/x) = tan⁻¹(5/5) = tan⁻¹(1) = 45°

The _____ in which ratio is expressed is important
In mathematics, a ratio is a comparison of two quantities or numbers expressed in terms of division. The order in which the quantities are expressed in a ratio is also important.
Ratios are used in various mathematical applications such as in finance, geometry, and physics. The units or quantities being compared in a ratio are crucial in determining the meaning and significance of the ratio.
For example, if the ratio is expressed as 2:1, it could mean that the first quantity is twice the size of the second quantity, or it could mean that the second quantity is half the size of the first quantity. Therefore, it is important to clearly define the units or quantities being compared to avoid any ambiguity or misunderstanding.
In the example above, if the ratio was expressed as 1:2 instead of 2:1, the meaning of the ratio would be reversed. Therefore, the order of the quantities in a ratio should be consistent with the context in which it is being used. In summary, the units and the order in which the quantities are expressed in a ratio are important in conveying accurate and meaningful information.

Let θ be equal to 855∘. Sketch θ in standard position. θ = 855∘ is in the fourth quadrant of the coordinate plane θ = 855∘
The given angle, θ, is a positive angle. It is measured in the counterclockwise direction from the initial side to the terminal side.Hence, we sketch θ in the standard position with its initial side along the positive x-axis.
Find an angle between 0∘ and 360∘ that is coterminal with θ.
The angle between 0∘ and 360∘ that is coterminal with θ is given by:
θ1 = θ - n × 360∘θ1 = 855∘ - 2 × 360∘θ1 = 855∘ - 720∘θ1 = 135∘

From midnight to 8:00 am, the temperature rose 1. 51. 5°C each hour. If the temperature at midnight was -3−3°C, what was the temperature at 8:00 am?
the temperature at 8:00 am is 9°C This means that every hour from midnight to 8:00 am, the temperature increased by 1.5°C, resulting in a total increase of 12°C over the 8 hour period.
To solve this problem, we need to use the formula for calculating the final temperature based on the initial temperature and the rate of change per hour.
The formula for this is:
Final Temperature = Initial Temperature + (Rate of Change per Hour x Number of Hours)
In this case, the initial temperature is -3°C, the rate of change per hour is 1.5°C, and the number of hours is 8.
Plugging these values into the formula, we get:
Final Temperature = -3 + (1.5 x 8)
Final Temperature = -3 + 12
Final Temperature = 9°C
Therefore, the temperature at 8:00 am is 9°C.
This means that every hour from midnight to 8:00 am, the temperature increased by 1.5°C, resulting in a total increase of 12°C over the 8 hour period.
It's important to note that this problem assumes that the rate of change per hour remains constant throughout the 8 hour period. In reality, the temperature may fluctuate based on various factors, such as wind, cloud cover, and humidity. However, for the purposes of this problem, we can assume that the rate of change per hour remains constant.

Find the solution(s) to the system, if it exists. State the solution as a point (be sure to use parentheses), use parameter(s) s and t if needed. If the system is inconsistent, then state no solution.
The system has infinitely many solutions, which can be written as (x, y, z) = (1 - 60s, -10 + 600s, s) where s is a parameter.
To solve the system of equations:
1x + 0y + 60z = 1
1x + 10y + 0z = 0
0x + 0y + 0z = 0
The third equation is an identity, implying that it does not give us any new information. The first two equations can be used to solve for x, y, and z:
From the first equation, we get x = 1 - 60z
From the second equation, we get y = 0 - 10x = -10(1 - 60z) = -10 + 600z
Therefore, the solution to the system can be written as a point in terms of z as:
(x, y, z) = (1 - 60z, -10 + 600z, z)
Since z can take on any value, there are infinitely many solutions to the system, which can be parameterized as:
(x, y, z) = (1 - 60s, -10 + 600s, s) where s is a parameter.
he system has infinitely many solutions, which can be written as (x, y, z) = (1 - 60s, -10 + 600s, s) where s is a parameter.

if the parametric equations for x and y are both non-constant linear functions of t, then must the curve be a line? if so, give an argument why this must be true. if not, explain and give a counter-example.
If the parametric equations for x and y are both non-constant linear functions of t, then curve must be a line.
A curve (sometimes known as a curved line in ancient texts) is a mathematical entity that is similar to a line but does not have to be straight.
A curve may be conceived of intuitively as the trace left by a moving point. "The [curved] line[a] is [...] the first species of quantity, which has only one dimension, namely length, without any width nor depth, and is nothing else than the flow or run of the point which [...] will leave from its imaginary moving some vestige in length, exempt of any width," Euclid wrote more than 2000 years ago.
Let x = at+b and y = ct+d
Then,
[tex]\frac{x-b}{a}=\frac{y-d}{c}=t xc-bc=ay-adxc-ay+ad-bc=0[/tex]
Which is linear equation in x and y.
Therefore, curve is always a line.

Agent Hunt is transferring classified files from the CIA mainframe into his flash drive. S(t) models the size of the files on the drive (in megabytes) after t seconds. S(t)=5t+45. What was the file size on the drive before the transfer? answer in megabytes
95 Gigabytes 1/3 Every 10 seconds, files are transmitted that are 10 times larger than the transfer rate as a whole. 2 / 3 The graph's slope is 5, according to the slope-intercept version of the equation for S. The unit rate is 5 gigabytes per second, according to this.
We are given the equation:- S(t)= 5t+45
calculate the value of S in 10s, 20s, 30s, ....... and difference in them.
for t= 10:-
S= 5(10)+45= 50+45= 95
for t= 20:-
S= 5(20)+45= 100+45=145
for t= 30:-
S= 5(30)+45= 150+45= 195
The difference:-
195-145= 50 and 145-95= 50
Hence, the file size is 50 MB per 10 seconds or 5 MB per second.
