three classes at a junior high school raised money to buy new computers
•ms moore’s class raised $249.00
•ms aguilars class raised $396.62 more than ms.moores class
•mr.barrys class raised $430.43 less than ms.augilars class
what is the total amount of money raised by all three classes
Answer:
$1109.81
Step-by-step explanation:
$249.00 +$369.62= $618.62(ms. aguilars class)
$618.92-$430.43= $188.19(mr. barry's class)
$249.00+$618.62+$188.19=$1109.81(complete answer of all 3 classes combined)
Answer:
The final amount is $1109.81
Step-by-step explanation:
In order to find the total amount, start with the know amount, which is Ms. Moore's class. Her class raised $249. Now we can use that to find the amount from Ms. Aguilar's class.
$249 + $396.62 = $645.62
Now we can use the amount from Ms. Aguilar's class to find the amount from Ms. Barry's class
$645.62 - $430.43 = $215.19
Now we can add the three amounts together to find the total amount.
$249 + $645.62 + $215.19 = $1109.81
Three people each select a letter of the alphabet. What is the probability that they select the same letter?
Final answer:
The probability that three people independently select the same letter of the alphabet is 1/676.
Explanation:
The question asks about the probability that three people select the same letter of the alphabet independently. Since there are 26 letters in the alphabet, the first person can pick any letter with a probability of 1 (they are sure to pick some letters). The second person must pick the same letter as the first, which has a probability of 1/26. Similarly, the third person also has a probability of 1/26 to pick the same letter as the first two. To find the combined probability for all three events happening in sequence (all three picking the same letter), we multiply the individual probabilities: 1 * (1/26) * (1/26) = 1/676.

Explain why the definitions of each rigid-motion transformation needs to be more precise than just referring to them as slides, flips and turns.
Answer:
Step-by-step explanation:
The definitions of rigid-motion transformations need to be precise as they entail more than physical descriptions of motions. They have unique mathematical definitions and are important for understanding and interpreting real-world movements and physical phenomena.
Explanation:The definitions of each rigid-motion transformation, namely slides (translations), flips (reflections), and turns (rotations), need to be more precise because they are not solely about the physical manifestation of the motion. These transformations have distinct mathematical underpinnings. For instance, a translation involves moving the figure along a specified direction and distance in a straight line, without changing the orientation of the figure. A reflection involves 'flipping' the figure over a line of reflection, altering its orientation but not its shape or size. A rotation involves turning the figure around a specified point for a given angle.
Moreover, in both rotational and translational motion - two forms of rigid-body motion, there are accurate variables such as displacement, velocity, and acceleration related to translational motion and the corresponding angular variables in rotational motion. These specific definitions are crucial for the mathematics behind movement and interpreting the world around us. Understanding such concepts can also aid in studying physical phenomena as diverse as a spinning ballet dancer or a rotating planet.

the table shows the number of minutes of exercise for each person. compare and contrast the measures of variation for both weeks. please answer quickly and thank you!
To compare the measures of variation for both weeks, calculate the range and standard deviation. Week 1 has a larger range and standard deviation compared to Week 2.
Explanation:
To compare and contrast the measures of variation for both weeks, we need to calculate the range and standard deviation for each week. The range is the difference between the highest and lowest values, while the standard deviation measures the average amount by which each data point differs from the mean.
For Week 1, the range is 90 (90 - 30), and the standard deviation is 25.62. For Week 2, the range is 30 (60 - 30), and the standard deviation is 11.55.
Therefore, Week 1 has a larger range and standard deviation compared to Week 2.

Select the representation that does not change the location of the given point. (4, 110°)
Question 6 options:
(4, 290)°
(-4, 200)°
(4, 470)°
(-4, 470)°
Answer:
(4,470°)
Step-by-step explanation:
The representation that does not change the location of (4, 110°) in polar coordinates are all points that are coterminal with the given point.
The only point among the given options that is coterminal with (4, 110°) is (4, 470)°
The two points have the same magnitude and 470°-360°=110°.
Since 110° is coterminal with 470° and the two points have the same magnitude with the same sign, the two points represent the same location in polar coordinates.
The correct choice is (4,470°)
In the polar coordinate system, the point (4, 470°) is the representation that does not change the location of the given point (4, 110°). We obtain this by adding 360° to the given angle.
Explanation:This question is based on the concept of polar coordinates. Polar coordinates represent a point in space by specifying its distance from a reference point, usually the origin, and the angle made with the positive x-axis. In polar coordinates, (r, θ), 'r' represents the distance and 'θ' is the angle.
Given point is (4, 110°). We can notice that by adding or subtracting multiples of 360° from the angle, we are not changing the location of the point. So, if we add 360° to the 110°, we will obtain 470°. Hence, the point that represents the same location is (4, 470°).
The point (-4, 200°) represents the point in the opposite direction and the points (4, 290°) and (-4, 470°) change the angle beyond or below what is allowable without changing the point's location.

A bicyclist covered 5/7 of his route and an additional 40 miles. He has yet to cover 118 miles less than 0.75 of his route. How long is his route in miles?
Answer:
6 miles
Step-by-step explanation:
Let the route length be r. The distance the cyclist has already covered is then (5/7)r + 40. This plus 0.75r - 118 must = r, the length of the entire route.
Then:
(5/7)r + 40 + (3/4)r - 118 = r
The LCD of the fractions 5/7 and 3/4 is 28. We thus have:
(20/28)r + 40 + (21/28)r - 118 = r, or
(41/28)r - 78 = (28/28)r
Combining the r terms, we get 13r = 78, and so r = 78/13 = 6.
The cyclist's bike route is 6 miles long.
Answer:
168 miles

ED decides to include more fruit in his diet he goes to the grocery store over the weekend and buys six apples six oranges six avocados the total cost is 19.50 write 3 Equations
Answer:
x = (19.5 - 6y - 6z) /6
y = (19.5 - 6x - 6z) /6
z = (19.5 - 6x - 6y) /6
Step-by-step explanation:
Let the Apples be X
Oranges be Y
Avocados be Z
Total cost of the Fruits = 19.5
So the equation would be as follows:
6x + 6y + 6z = 19.5
for Apples, equation would be:
6x= 19.5 - 6y - 6z
x = (19.5 - 6y - 6z) /6
For Oranges, the equation would be:
6y= 19.5 - 6x - 6z
y = (19.5 - 6x - 6z) /6
For Avocados, the equation would be:
6z= 19.5 - 6x - 6y
z = (19.5 - 6x - 6y) /6
Answer:
simple answer
Step-by-step explanation:
Let x be the cost of one apple, y the cost of one orange, and z the cost of one avocado.
The first weekend, Ed buys 6 of each fruit and pays $19.50: 6x+6y+6z=19.5
The second weekend, Ed buys 12 apples, 2 oranges, and 1 avocado and pays $9.50: 12x+2y+z=9.5
The third weekend, Ed buys 2 apples, 4 oranges, and 5 avocados and pays $14: 2x+4y+5z=14.

The point (2, 3) is on the terminal side of angle Θ, in standard position. What are the values of sine, cosine, and tangent of Θ?
Answer:
sin Ф = 3/√13; cos Ф = 2/√13; and tan Ф = 3/2
Step-by-step explanation:
Let's assume we're limiting ourselves to Quadrant I.
Start with the tangent function. tan Ф = opp / adj.
In this case opp = 3 and adj = 2.
The length of the hypotenuse is found using the Pythagorean Theorem and is √(3² + 2²) = √13.
Then sin Ф = opp / hyp = 3/√13 or 3√13/13
and
cos Ф = adj / hyp = 2/√13 or 2√13/13
and (as before)
tan Ф = opp / adj = 3/2
sin(θ) is approximately 0.832
cos(θ) is approximately 0.555
tan(θ) is 1.5
The given parameters are;
The location of point (2, 3) = The terminal side of angle θ in standard position
The required parameters;
sin of θ, cosine of θ, and tangent of θ
Strategy;
Draw angle θ on the coordinate plane based on definition showing point (2, 3) on the terminal side and find the required trigonometric ratio
Standard position is the position of an angle that has the vertex at the
origin, the fixed side of the angle is on the x-axis and the terminal side
which defines the angle is drawn relative to the initial fixed side to form
the given angle either clockwise or anticlockwise
We have the following trigonometric ratios with regards to the reference angle;
[tex]sin\angle X = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
The hypotenuse length = √(2² + 3²) = √13
Therefore;
[tex]\mathbf{sin( \theta)} = \dfrac{3 - 0}{\sqrt{13} }= \dfrac{3}{\sqrt{13} } = \mathbf{\dfrac{3 \cdot \sqrt{13} }{13}}[/tex]
[tex]\mathbf{sin( \theta)} \ is \ \mathbf{\dfrac{3 \cdot \sqrt{13} }{13}} \approx 0.832[/tex]
[tex]cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]
Therefore
[tex]\mathbf{cos( \theta)} = \dfrac{2 - 0}{\sqrt{13} }= \dfrac{2}{\sqrt{13} } =\mathbf{ \dfrac{2 \cdot \sqrt{13} }{13 }}[/tex]
[tex]\mathbf{cos( \theta)} \ is \ \mathbf{ \dfrac{2 \cdot \sqrt{13} }{13 }} \approx 0.555[/tex]
[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]
The hypotenuse length = √(2² + 3²) = √13
Therefore;
[tex]\mathbf{tan( \theta)} = \dfrac{3 - 0}{2 - 0 } \mathbf{=\dfrac{3}{2 }}[/tex]
tan(θ) = 1.5

Answer:
x = 20
∠B = 92
∠C = 40
Step-by-step explanation:
im pretty sure
Answer:
x = 20. ∠B = 92° and ∠C = 40°
Step-by-step explanation:
Angles of a triangle are ∠A = 48°, ∠B = (6x - 28)° and ∠C = (2x)°
Since sum of all the angles of the triangle is 180°
So ∠A + ∠B + ∠C = 180°
48° + (6x - 28)° + (2x)° = 180°
48 + 6x - 28 + 2x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = [tex]\frac{160}{8}=20[/tex]
Now ∠B = (6x - 28) = 6×20 - 28
∠B = 120 - 28 = 92°
And ∠C = 2x° = 2×20 = 40°
Therefore, x = 20. ∠B = 92° and ∠C = 40° is the answer.

Required ratio is 2:5.
Step-by-step explanation:
Given that number of female nurses = 250
Given that number of male nurses = 100
Now we need to find about what is the ratio of male nurses to female nurses.
So we just need to divide number of male nurses by the number of female nurses. That means divide 100 by 250. We get:
[tex]\frac{male}{female}=\frac{100}{250}[/tex]
[tex]\frac{male}{female}=\frac{10}{25}[/tex]
[tex]\frac{male}{female}=\frac{2}{5}[/tex]

The measure of a vertex angle of an isosceles triangle is 120° and the length of a leg is 8 cm. Find the length of a diameter of the circle circumscribed about this triangle.
ANSWER
The length of a Diameter is 3.714
EXPLANATION
The circumscribed triangle is shown in the attachment.
We use the cosine ratio to find the altitude of the isosceles triangle.
[tex] \cos(60 \degree) = \frac{altitude}{hypotenuse} [/tex]
[tex] \cos(60 \degree) = \frac{altitude}{8} [/tex]
Altitude =8cos(60°)
Altitude=4cm
Let the upper half of the altitude be y cm.
Then the radius of the circle is (y-4)cm
The upper radius meets the tangent at right angles.
From the smaller right triangle,
[tex] \sin(60 \degree) = \frac{4 - y}{y} [/tex]
[tex] y\sin(60 \degree) = 4 - y[/tex]
[tex]y\sin(60 \degree) + y= 4 [/tex]
[tex](\sin(60 \degree) + 1)y= 4 [/tex]
[tex]y= \frac{4}{\sin(60 \degree) + 1} [/tex]
[tex]y = 16 - 8 \sqrt{3} [/tex]
y=1.857
The diameter is 2y
[tex]d = 32 - 16 \sqrt{3} [/tex]
=2(1.875)
The length of a Diameter is 3.714
Answer:
Diameter of the circle is 16 cm.
Step-by-step explanation:
Given : The measure of a vertex angle of an isosceles triangle is 120° and the length of a leg is 8 cm.
To find : The length of a diameter of the circle circumscribed about this triangle?
Solution :
We construct a circle in which an ABC isosceles triangle is formed.
Refer the attached figure below.
The measure of a vertex angle of an isosceles triangle is 120° .
The length of a leg is 8 cm, AC=8 cm
Vertex angle is divided by the line touching the center of the circle.
So, [tex]\angle A=60^\circ[/tex] and line AD=radius of the circle
Applying property of isosceles triangle,
Now, ∠DAC=∠ACD=∠CDA=60°
AC=DC=8 cm
The radius of the circle is 8 cm.
The diameter of the circle is twice the radius.
Therefore, The diameter of the circle is d=2(8)=16 cm.
