Which situation results in a final value of zero?
A. The overall change in temperature when the temperature goes from -10 degrees fahrenheit, to 10 degrees fahrenheit.
B. The total profit made from when a person buys an item for $2.25, and then sells the item for $2.25.
C. The overall change in altitude in a hot air balloon after rising 21 kilometers from sea level.
D. The total distance a person travels when he bikes 3.1 miles to school and the bikes 3.1 miles back home.
Answer:
B
Step-by-step explanation:
The profit made is equal to 2.25-2.25 which is 0.
The situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero. which is the correct answer would be an option (B).
What is the distance?Distance is defined as the product of speed and time.
As per option (A),
The overall change in temperature = 10 - (-10) = 20 degrees
As per option (B),
The profit made is equal to 2.25 - 2.25 = 0 which is zero.
As per option (C),
The overall change in altitude = 21 - 0 = 21 kilometers
As per option (D),
The total distance traveled by person = 3.1 + 3.1 = 6.2 miles
Thus, the situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero.
Hence, the correct answer would be option (B).

What is the equation of a line that passes through points (0, 4) and (-4, -8)? y = 2x + 4 y = 2x - 4 y = 3x + 4 y = 3x - 4
Answer:
y= 3x +4
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx +c, where m is the gradient and c is the y-intercept.
To find the value of m, use the gradient formula below:
[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]
Gradient
[tex] = \frac{4 - ( - 8)}{0 - ( - 4)} \\ = \frac{4 + 8}{0 + 4} \\ = \frac{12}{4} \\ = 3[/tex]
Subst. m=3 into the equation.
y= 3x +c
To find the value of c, substitute a coordinate.
When x=0, y=4,
4= 3(0) +c
c=4
Thus, the equation of the line is y= 3x +4.
An angle measures 120 degrees. Describe how to use special right triangles and the unit circle as tools to calculate the sine and cosine of this angle.
Answer:
We know that, for a right triangle:
Cos(A) = (adjacent cathetus)/hipotenuse
sin(A) = (opposite cathetus)/Hipotenuse.
If we are in a right triangle inside the unit circle, we have that hypotenuse = 1.
Now, when you draw the unit circle, now from the center of the axis you must draw a straigth line (that forms an angle of 120° with the x-axis), and in the point where it cuts the unit circle we do 2 things.
from this point, you can draw a parallel line to the y-axis, the point where this line touches the x-axis is the value of the cosine.
Now you draw a line that is parallel to the x-axis (remember that the line must pass trough the point of before), the point where this line cuts the y-axis is the value of the sine
You should get:
sin(120°) = 0.87
cos(120°) = -0.5

Step-by-step explanation:
Since Rita is trying to prove that the two triangles are similar, she will be looking for corresponding sets of sides that have an equivalent ratio. Therefore, since for the big triangle she uses sides PQ and PR, the corresponding sides on the smaller triangle would be PS and PT, which have a ratio of 28:35. Hope this helps!
The statement is completed by 28 :35, the correct option is B.
What are Similar Triangles?Two triangles of the same shape are said to be similar when their corresponding sides are proportional.
The triangle RPQ
The length of PS is equal to 28
The length of SQ is equal to 2x
The length of PT is equal to 35
The length of TR is equal to 60
The triangles SPT and QPR are proved to be similar in Step 4 by the property that corresponding sides of similar triangles are in proportion.

6(3p – 1) = 84 can you help me with this question please? i am struggling to explain this to my son. thanks in advance.
On photos i showed 2 ways of possible solutions
Answer: p=5
Step-by-step explanation:
6(3p-1)=84
You can now do it two ways. This is the first way:
Divide by 6 so the equation now writes:
3p-1= 14
Then add the one onto the other side.
3p=15
Then divide 15 by 3
P=5
The other way is to expand the brackets first.
18p-6=84
Then add the 6 onto the other side.
18p=90
Then divide 90 by 18.
P=5
This is a bit more complex so I recommend the first way. Hope you can now explain to your son. Have an amazing day!

The measure of one supplementary angle is 45 degrees more than twice the measure of the other. Write an equation to find the measure of each angle. Solve to find each angle
Answer:
45 , 135
Step-by-step explanation:
LET ONE ANGLE BE x AND OTHER ANGLE BE 45+2x
since they are supplementary angles ,
x+2x+45=180
3x = 180 -45
3x = 135
x = 135/3
x =45 degree
therefore measure of one angle = 45 degree and other angle angle = 2*45+45 = 90+45 = 135 degree

2.7 * 10 ^-5 / 9 * 10 ^-6
First divide the numbers
2.7 / 9 = .3
Then divide the exponents
10^-5 / 10 ^ -6
When we divide exponents we subtract
10^(-5 - -6) = 10 ^1
.3 * 10 ^1
But scientific notation has a number between 1 and less than 10
Move the decimal 1 place to the left, so we subtract 1 from the exponent

A fence with four sections has a perimeter of 43 ft. Three of the sections have lengths of 8 ft, 12 ft, and 11 ft. What is the length of the fourth section?
x = 43 + 8 + 12 + 11
x + 8 + 12 + 11 = 43
x – 8 + 12 +11 = 43
x – 43 = 8 + 12 –11
Answer:
x + 8 + 12 + 11 = 43
Step-by-step explanation:
The perimeter is the length of the 4 sections of fencing.
If x represents the fourth section and the perimeter is 43, then
x + 8 + 12 + 11 = 43, that is
x + 31 = 43 ( subtract 31 from both sides )
x = 12
The length of the fourth section is 12 ft

What is Area?Area is the quantity that expresses the extent of a region on the plane or on a curved surface.
Given,
Short base a = 145 yards
Long base b = 225 yards
Height h = 80 yards
Area of the park = [tex]\frac{a+b}{2}h[/tex]

Question 2
The measures of two supplementary angles are in the ratio of 2: 3. Find the measurements of the two angles.
Question 3
In a pair of complementary angles, the measurement of the larger angle is three times that of the smaller angle. Find the measurements of the two angles.
Answer:
1 ) m∠ 1 = 72°, m∠2 = 108°,
2 ) m∠ 1 = 22.5°, m∠2 = 67.5°
Step-by-step explanation:
Question 2 ) Assuming these are supplementary angles, we know that their measures form a linear pair that add to 180°;
let us assign these angles as 1, and 2 ⇒ m∠ 1 + m∠ 2 = 180,
with the given ratios 2 to 3, we can say x ⇒ one part of measure, so that ⇒ 2x + 3x = 180,
2x + 3x = 180 ⇒ combine like terms,
5x = 180 ⇒ divide either side by 5,
x = 36°
If this is so, m∠ 1 = 2x = 2 * ( 36 ) = 72°, and m∠ 2 = 3x = 3 * ( 36 ) = 108°;
Solution; m∠ 1 = 72°, m∠2 = 108°
Question 3 ) If it is known that two angles are complementary to one another, we can say their measures add to 90°;
let us one more, assign these angles as 1 and 2 ⇒ m∠ 1 + m∠ 2 = 180,
knowing that the measure of one angle is 3 times that of the other angle we can derive the ratio 1 : 3 in the manner smaller ∠ measure : bigger ∠ measure so that ⇒ x + 3x = 90,
x + 3x = 90 ⇒ combine like terms,
4x = 90 ⇒ divide either side by 4,
x = 22.5
If this is so, m∠ 1 = x = 1 * ( 22.5 ) = 22.5°, and m∠ 2 = 3x = 3 * ( 22.5 ) = 67.5°;
Solution; m∠ 1 = 22.5°, m∠2 = 67.5°

Answer: x8 i really don't know if it is correct tell me plz
Step-by-step explanation:
The expression (x²)⁴ without exponents can be written as x × x × x × x × x × x × x × x.
The given expression is (x²)⁴.
It is known that the power rule of exponents states that:
(xᵃ)ᵇ = xᵃᵇ
Here, a = 2 and b = 4.
So using the power rule,
(x²)⁴ = x²⁽⁴⁾
= x⁸
Now, it is known that exponents are actually the multiplication of the number with the same number again and again.
Here x is multiplied by itself 8 times.
So the expression can be written as:
