Which values of x will make the absolute value equation true? |x – 3| = 40
A. {–43, –37}
B. {43, –37}
C. {40, –40}
D. {43, 37}
The values of x that satisfy the absolute value equation |x – 3| = 40 are 43 and -37. These are derived from solving the two possible scenarios for absolute value equations, resulting in a positive and a negative solution.
Explanation:To find which values of x will make the absolute value equation |x – 3| = 40 true, we need to consider both the positive and negative scenarios that can result from the absolute value. The absolute value of a number equals the number itself if it is positive or zero, and it equals the negative of the number if it is negative.
So, we set up two equations:
x - 3 = 40 (when x – 3 is non-negative)x - 3 = -40 (when x – 3 is negative)Solving the first equation for x, we add 3 to both sides:
x = 40 + 3
x = 43
Solving the second equation for x, we add 3 to both sides:
x = -40 + 3
x = -37
Therefore, the values of x that will satisfy the equation are 43 and -37. Option D is the correct answer.
Final answer:
The values of x that make the absolute value equation true are 43 and -37.
Explanation:
To solve the equation |x-3| = 40, we need to consider two cases:
1. x-3 = 40: In this case, we add 3 to both sides to isolate x and get x = 43.
2. -(x-3) = 40: In this case, we distribute the negative sign and add 3 to both sides to isolate x, which gives x = -37.
Therefore, the values of x that make the absolute value equation true are {43, -37}.

A piece of solid, spherical glass has a circumference of 18.84 centimeters. The sphere is cut in half, creating two identical hemispheres. Using 3.14 for π, Tran computes the amount of paint needed to cover the sphere. Which statement about the amount of paint found by Tran is true?
Tran found the minimum amount of paint needed to cover the curved surface of a hemisphere
Tran found the minimum amount of paint needed to cover the entire surface of one of the hemispheres.
Tran found the minimum amount of paint needed to cover both hemispheres.
Tran found the minimum amount of paint needed to cover the bases of both hemispheres.
Final answer:
Tran must calculate the surface area of the hemisphere, including the base, to determine the amount of paint needed, which is the sum of half the surface area of the sphere and the area of the base.
Explanation:
The question is asking what Tran would compute when using π to determine the amount of paint required for a hemisphere. First, Tran needs to calculate the surface area of the sphere to determine the paint needed. Given the circumference C = 18.84 cm, the radius r can be found using C = 2πr, which gives us a radius of r = C / (2π). Once we have the radius, we can find the surface area A of the sphere using A = 4πr², which is necessary to determine the paint needed for the outer surface.
However, when the sphere is cut into two hemispheres, the flat face of each hemisphere (base) also needs paint. The area of the base is a circle with an area of πr². Thus, the total surface area that Tran would need to paint for one hemisphere, including the base, is πr² + 2πr² (half of the sphere's surface area).
Final answer:
Option D.) Tran found the minimum amount of paint needed to cover both hemispheres.
Explanation:
Tran found the minimum amount of paint needed to cover both hemispheres. To calculate the amount of paint needed to cover a hemisphere, we need to find the surface area of the hemisphere. The formula for the surface area of a sphere is 4πr², where r is the radius.
Given that the circumference of the sphere is 18.84 centimeters, we can use the formula C = 2πr to solve for the radius. Plugging in the value for C, we get 18.84 = 2πr.
Simplifying the equation, we find that the radius of the sphere is approximately 3 centimeters.
The surface area of a hemisphere is half the surface area of a sphere, so the surface area of one hemisphere is 2πr²/2 = πr².
Substituting the value of r, we find that the surface area of one hemisphere is approximately 9π square centimeters.
Since Tran cut the sphere in half and created two identical hemispheres, the minimum amount of paint needed to cover both hemispheres would be twice the surface area of one hemisphere, which is approximately 18π square centimeters.
For a circle with a diameter of 6 meters, what is the measurement of a central angle (in degrees) subtended by an arc with a length of 7 3 π meters?
Answer : The measurement of a central angle is, [tex]140^o[/tex]
Step-by-step explanation :
Formula used for angle subtended by an arc is:
[tex]s=\frac{\pi r\theta}{180}[/tex]
where,
s = arc length = [tex]\frac{7}{3}\pi m[/tex]
r = radius = [tex]\frac{diameter}{2}=\frac{6m}{2}=3m[/tex]
Now put all the given values in the above formula, we get:
[tex]s=\frac{\pi r\theta}{180}[/tex]
[tex]\frac{7}{3}\pi=\frac{\pi \times (3)\times \theta}{180}[/tex]
[tex]\theta =140^o[/tex]
Thus, the measurement of a central angle is, [tex]140^o[/tex]
does 6% of a pound weigh more than an ounce
Answer:
6% of a pound does not weigh more than 1 ounce.
Step-by-step explanation:
First, we will calculate 6% (0.06) of 1 pound.
0.06 × 1 lb = 0.06 lb
1 pound is equal to 16 ounces. 0.06 pounds, expressed in ounces is:
0.06 lb × (16 oz/ 1 lb) = 0.96 oz
6% of a pound = 0.96 oz
0.96 oz < 1 oz
Due to the transitive property, we can affirm that 6% of a pound does not weigh more than 1 ounce.

Two numbers add to 336 and the first is 124 bigger than the second. What are the two numbers?
Final answer:
To solve the problem, a system of equations is set up with the second number as 'x' and the first as 'x + 124.' The equations are simplified to find 'x = 106,' which makes the first number '230.' The two numbers are 106 and 230.
Explanation:
To find the two numbers that add to 336 and where the first number is 124 larger than the second, we need to set up a system of equations based on the information given:
Let the second number be x.
Then the first number will be x + 124 since it is 124 bigger than the second.
The sum of the two numbers is 336, so we can write the equation x + (x + 124) = 336.
Simplifying this equation, we get 2x + 124 = 336.
Subtract 124 from both sides to isolate the term with x, yielding 2x = 212.
Divide both sides by 2 to find x, which gives x = 106.
Since the first number is 124 larger, we add 124 to 106, resulting in the first number being 230.
Therefore, the two numbers are 106 and 230.

Step-by-step explanation:
When p2 – 4p is subtracted from p2 + p – 6, the result is 5p-6 To get p – 9, subtract
Subtract p² - 4p from p² + p - 6 to get 5p - 6. To obtain p - 9, subtract 15 from 5p - 6.
Let's break it down step by step:
1. Subtracting p² - 4p from p² + p - 6:
Start by writing down the expression p² + p - 6.
Now, subtract p² - 4p from it term by term.
(p² + p - 6) - (p² - 4p)
2. Expand and Simplify:
Distribute the subtraction across each term inside the parentheses:
p² + p - 6 - p² + 4p
This simplifies to: (p² - p²) + (p + 4p) - 6
= 0 + 5p - 6
= 5p - 6
3. Now, to get p - 9:
We want to manipulate 5p - 6 to p - 9.
Subtracting 15 from 5p - 6 gives:
5p - 6 - 15
= 5p - 21
Therefore, subtracting 5p - 21 from 5p - 6 results in p - 9.
