Which of these best describes an undefined term?
A. A term that is a building block for other definitions in geometry
B. A clause in a conditional statement that begins with "then"
C. A statement that has already been proven to be true
D. A statement that is the opposite of an original statement
Answer:
A. A term that is a building block for other definitions in geometry.Step-by-step explanation:
In Geometry, undefined terms refer to concepts like point, line and plane. Which are concepts that cannot be defined, they are too intuitive. Undefined terms are always true, they cannot be prove because those concepts are too primitive.
It's important to know that Geometry develops another complex defintions from these undefined terms, beacuse point, line and plane are the fundamentals of Geometry.
Therefore, the right answer is A.
Other choices are just wrong, because undefined terms aren't condition statments, they cannot be proven and they aren't oppsite of an original statement.

find the missing number
9/10 minus blank = 1/5
The missing number in the equation 9/10 minus blank = 1/5 is 7/10. To find this, we converted 1/5 to the common denominator of 10, resulting in 2/10, and subtracted it from 9/10.
Explanation:To find the missing number in the equation 9/10 minus blank = 1/5, we need to subtract 1/5 from 9/10. To do calculations with fractions, it's essential to have a common denominator. In this case, the least common denominator for 10 and 5 is 10. We need to express 1/5 as 2/10 to match the denominator of 9/10.
Next, we subtract the two fractions:
9/10 - 2/10 = 7/10So, the missing number is 7/10, because 9/10 minus 7/10 equals 1/5. This result becomes clear with the common denominators, as we are able to subtract the numerators directly while keeping the denominator.
Final answer:
To solve for the missing number in the equation 9/10 minus blank equals 1/5, we find a common denominator, move like terms, and solve for x, yielding the missing number 7/10.
Explanation:
To find the missing number in the equation 9/10 minus blank equals 1/5, we need to isolate the blank (let's call it x). To do this, we'll move all known values to one side of the equation.
Start with:
9/10 - x = 1/5
Add x to both sides:
9/10 = x + 1/5
Now, find a common denominator which is 10 in this case, to combine the fractions. This gives us:
9/10 = (x ⋅ 10/10) + (2/10)
Keep in mind, the arithmetic of common denominators to simplify the equation.
Combine like terms:
9/10 = (10x + 2)/10
Multiply both sides by 10 to get rid of the denominator:
9 = 10x + 2
Subtract 2 from both sides:
7 = 10x
Finally, divide by 10:
x = 7/10
So, the missing number is 7/10.

What is the volume of this square pyramid?
384 cm³
288 cm³
192 cm³
96 cm³
The required volume of the square pyramid is 3[tex]84 cm$^3$[/tex]. The answer is option A.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Here,
The formula for the volume of a square pyramid is:
[tex]$V = \frac{1}{3}Bh$[/tex]
Where B is the base area and h is the pyramid's height.
In this case, the base is a square with a side length of 12 cm, so its area is:
[tex]B = 12^2 = 144cm$^2$[/tex]
The height of the pyramid is 8 cm.
Plugging these values into the formula, we get:
[tex]V = \frac{1}{3}(144)(8) = 384$ cm$^3[/tex]
Therefore, the volume of the square pyramid is 3[tex]84 cm$^3$[/tex]. The answer is option A.

Bryan cuts a piece of cardboard in the shape of a trapezoid. The area is 43.5 square centimeters. If the bases are 6 centimeters and 8.5 centimeters long, what is the height of the trapezoid?
To find the height of the trapezoid, use the formula for the area of a trapezoid: A = ((b1 + b2) * h) / 2. Plug in the given values and solve for h.
Explanation:To find the height of the trapezoid, we can use the formula for the area of a trapezoid: A = ((b1 + b2) * h) / 2, where A is the area, b1 and b2 are the lengths of the bases, and h is the height. In this case, the area is given as 43.5 square centimeters, and the lengths of the bases are 6 centimeters and 8.5 centimeters. Plugging in these values, we get:
43.5 = ((6 + 8.5) * h) / 2
Simplifying the equation, we have:
87 = 14.5h
Dividing both sides by 14.5, we find:
h = 6 centimeters

Height of the trapezoid is 6 centimeters.
Area = (1/2) × (Base1 + Base2) × Height
Given the following values:
Area = 43.5 square centimetersBase1 = 6 centimetersBase2 = 8.5 centimetersWe can plug these values into the formula and solve for the height:
43.5 = (1/2) × (6 + 8.5) × Height
43.5 = (1/2) × 14.5 × Height
43.5 = 7.25 × Height
To isolate the height, divide both sides by 7.25:
Height = 43.5 / 7.25
Height = 6 centimeters
So, the height of the trapezoid is 6 centimeters.

In one gram of substance 0.22 grams of nickel is present. Then the amount of nickel in the 35 grams of the substance is 7.7 grams.
What are ratio and proportion?A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.
A single gram of a certain metallic substance has 0.52 grams of copper and 0.26 grams of zinc.
The remaining portion of the substance is nickel.
Let the gram of nickel be x. Then we have
x + 0.52 + 0.26 = 1

Kyra exercises at a gym for 1 2/3 hours. she stretches,lifts weights, runs, and showers. kyra spends 1/4 hour stretching 1/3 hour showering.how much time does kyra spend running?
Final answer:
To determine the time Kyra spends running, the time spent on stretching and showering is subtracted from the total gym time, resulting in 65 minutes of running.
Explanation:
Kyra exercises at the gym for a total of 1 2/3 hours. To calculate the time she spends running, we need to subtract the time spent on other activities from the total exercise time. First, convert 1 2/3 hours to an improper fraction: (1 × 3) + 2 = 3 + 2 = 5/3 hours. Now, let's convert this into minutes: 5/3 hours × 60 minutes/hour = 100 minutes.
Next, calculate the total time spent stretching and showering: (1/4 hour × 60 minutes/hour) + (1/3 hour × 60 minutes/hour) = 15 minutes + 20 minutes = 35 minutes.
Finally, to find out how much time Kyra spends running, subtract the time spent on stretching and showering from the total exercise time: 100 minutes - 35 minutes = 65 minutes spent running
Kyra spends 1 hour and 5 minutes running at the gym.
Explanation:To find out how much time Kyra spends running, we need to subtract the time she spends stretching and showering from the total time she exercises at the gym.
Given that Kyra spends 1 2/3 (or 5/3) hours at the gym, and 1/4 hour stretching and 1/3 hour showering, we can calculate:
Total time Kyra spends stretching and showering = 1/4 + 1/3 = 3/12 + 4/12 = 7/12 hours
Time Kyra spends running = Total time at the gym - Total time Kyra spends stretching and showering = 5/3 - 7/12 = 20/12 - 7/12 = 13/12 hours.
Therefore, Kyra spends 13/12 hours or 1 hour and 5 minutes running.

The height in feet h of a water bottle rocket launched from a rooftop is given by the equation h = -16t2 + 320t + 32, where t is the time in seconds. After the rocket is fired, how long will it take to return to the ground? Solve by completing the square. Round your answer to the nearest tenth of a second.
Final answer:
It will take approximately 20.2 seconds for the water bottle rocket to return to the ground after being launched, determined by solving the given quadratic equation by completing the square.
Explanation:
The question asks how long it will take for a water bottle rocket launched from a rooftop to return to the ground, given the equation h = -16t2 + 320t + 32, where h is height in feet and t is time in seconds. To find when the rocket hits the ground, we need to solve for t when h equals zero by completing the square.
First, rearrange the equation: 0 = -16t2 + 320t + 32.
Factor out -16 to simplify: 0 = -16(t2 - 20t - 2).
To complete the square, take half of the -20, square it and add to both sides: 100 + 2 = -16(t2 - 20t + 100).
This simplifies to 0 = -16((t - 10)2 + 98) and then (t - 10)2 = -98/(-16).
Solve for t: t = 10 + sqrt(98/16), which gives approximately t = 20.2 seconds.
Therefore, it will take approximately 20.2 seconds for the water bottle rocket to return to the ground.
