Final answer:
The diameter of a circle with a radius of 1 foot is 2 feet.
Explanation:
The radius of a circle is half the diameter. So, if the radius (r) of a circle is given as 1 foot, the diameter (d) is simply twice the radius. Therefore, the diameter is:
d = 2 × r
d = 2 × 1 ft
d = 2 ft
Hence, the diameter of the circle is 2 feet.

Jana is ordering a list of numbers from least to greatest.
StartRoot 7 squared EndRoot, StartRoot 7 EndRoot, Four-fifths, StartRoot 0.8 EndRoot, (StartRoot 5 EndRoot) Squared
Which statement can be used to create her list?
A: StartRoot 0.8 EndRoot is less than Four-fifths because 0.8 = four-fifths and the square root of a number less than 1 is less than the number itself.
B: StartRoot 7 EndRoot is greater than StartRoot 7 squared EndRoot because StartRoot 7 squared EndRoot = 7 and the square root of a number greater than 1 is greater than the number itself.
C: (StartRoot 5 EndRoot) squaredis less than StartRoot 7 EndRoot because (StartRoot 5 EndRoot) squared = 5 and StartRoot 7 EndRoot is between 6 and 8.
D: StartRoot 7 EndRoot is greater than Four-fifths because Four-fifths is less than 1 and the square root of a number greater than 1 is greater than 1.
Answer:
The correct option is D
Step-by-step explanation:
The given numbers are
√(7²), √7, 4/5, √0.8, (√5)²
Now, let us check their real values.
√(7²) = 7
√7 ≈ 2.646
4/5 = 0.8
√0.8 ≈ 0.894
(√5)² = 5
Now, checking the options,
A doesn't apply
B doesn't appy
C doesn't apply
D applies because √7 = 2.646 is greater than 4/5 = 0.8 because 4/5 is less than 1 and the square root of a number greater than 1 is greater than 1.

The tangents of the acute angles in a right triangle can be calculated by taking the ratio of the side opposite the angle to the side adjacent to the angle.
Explanation:In a right triangle, the tangent of an acute angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. Let's say the acute angles of the right triangle are A and B, and the sides opposite to them are denoted as A and b, respectively. Then, the tangents of the angles A and B can be calculated as:
Tan(A) = a/b

By mistake, you added salt instead of sugar to the
oil. How can you remove the salt?
Answer: Evaporate the water by boiling it in a pot with a lid or another container. This separates both substances as the boiling point for water is much lower than salt, this method is called simple distillation.
Answer:
Salt is ionic, and oil is covalent. If you add water, the salt will dissolve in the water, and the oil will float to the top. You could then skim the oil and start over with sugar. To double-check, you could even make sure the oil does not conduct electricity!

A student wants to sign up for a swimming class that charges $5 an hour. His parents are willing to spend up to $100 for swimming
lessons. Write an inequality representing the possible number of hours he could take swimming lessons for.
Answer:
[tex]x\leq 20[/tex]
Step-by-step explanation:
Given:
Charges of one hour swimming class = $5
Maximum amount that parents are willing to spend for swimming = $100
To find: inequality representing the possible number of hours, a student could take swimming lessons
Solution:
An inequality compares two values such that either one value is less than, greater than, or not equal to another value.
Let x represents number of hours spend by a student in swimming class.
As maximum amount that parents are willing to spend for swimming is $100 and charges of one hour swimming class is $5,
[tex]5x\leq 100\\x\leq \frac{100}{5} =20\\x\leq 20[/tex]

The collection of data points that answer a statistical question is called
A) center
B) distribution
C) shape
D) spread
The correct answer is B) distribution.
A statistical distribution refers to the collection of data points that provide information about how a particular variable is spread or distributed across different values.
In other words, it describes the frequency or likelihood of each possible outcome or observation within a dataset.
Understanding the distribution of data is essential in statistics because it helps us analyze and make predictions about various phenomena. Common types of distributions include the normal distribution, uniform distribution, and exponential distribution, among others.
Statistical distributions are characterized by their center (average or median), shape (how the data is spread out), and spread (how much variation exists within the data).
These three aspects collectively provide valuable insights into the data's overall behavior and are fundamental for statistical analysis and decision-making.
Therefore, when we talk about the collection of data points that answer a statistical question, we are referring to the distribution of the data, which encapsulates important information about its characteristics.

The greatest common factor of 14 and 38
Answer:
2
Step-by-step explanation:
when you order all their GCF's, going backwards, you can see that both of them are divisible by 2. Hope this helps! If you are still confused please comment!
The greatest common factor of numbers 14 and 38 is 2.
To find the greatest common factor (GCF) of 14 and 38, we can determine the largest positive integer that divides both numbers evenly.
To begin, let's find the factors of each number:
Factors of 14: 1, 2, 7, 14
Factors of 38: 1, 2, 19, 38
The common factors between 14 and 38 are 1 and 2.
However, the greatest common factor, so the GCF is 2.
Therefore, the greatest common factor of 14 and 38 is 2.

Drag each number to the correct location on the equation. Not all numbers will be used.
ABC and RST are similar and have the same orientation. The hypotenuse of RST is on the same line as the hypotenuse of ABC and is twice the length of AB.
What is the equation of the line that contains the hypotenuse of RST?
-18
9
3
-6
-3
-9
6
18
Answer:
The equation of the hypotenuse line is y = -3·x + 9
Therefore, the correct options are -3 and 9
Step-by-step explanation:
The question asks to fill the boxes
y = _ x + _
We note that the equation is that of a straight line of the form;
y = m·x + c
Where:
m = Slope of the straight line graph and
c = Y intercept, that is the y-coordinate of the point on the line where x = 0
From the graph, we find the slope as follows;
[tex]Slope = \frac{y_2 - y_1}{x_2 -x_1} = \frac{(-9) -0}{6-3} = -3[/tex]
Therefore, m = -3
The y intercept is found by extending the hypotenuse line to the point where it touches the y axes that is at x = 0;
From the graph, it is observed that the line, when extended, touches the y axes at the point y = 9, therefore, c = 9
Hence we have, the equation of the hypotenuse line is y = -3·x + 9.
Answer:
y = -3x + 9

Round 6.9824 to the nearest tenth.
Answer:
6.9824 rounded to the nearest tenth is 6.9. But i am pretty sure the correct answer is 7
Step-by-step explanation:
6.9824 rounded to the nearest tenth is 6.99.
To round 6.9824 to the nearest tenth, we look at the hundredth place, which is 8 in this case. Since 8 is greater than or equal to 5, we round the digit in the tenth place up by 1.
So, rounding 6.9824 to the nearest tenth:
1. Identify the hundredth place: 8
2. Since 8 is greater than or equal to 5, we round the digit in the tenth place up by 1.
3. The digit in the tenth place is 9.
4. The number becomes 6.99.
