This results in a final answer of 94.
The question asks for the calculation of 2 times the difference of 73 and twice the sum of 9 and 4. Let's break it down step by step:
First, calculate the sum of 9 and 4, which is 9 + 4 = 13.Next, multiply this sum by 2 to get twice the sum, which results in 13 imes 2 = 26.The difference between 73 and the result from step 2 is 73 - 26 = 47.Finally, multiply that difference by 2 as per the question, giving us 47 imes 2 = 94.Therefore, 2 times the difference of 73 and twice the sum of 9 and 4 equals 94.
A cylinder has a radius of 14 m and a height of 6 m.
What is the exact volume of the cylinder?
84m^3
168m^3
504 m^3 1176m^3
Option D: [tex]1176 \pi \ {m}^{3}[/tex] is the volume of the cylinder
Explanation:
Given that the cylinder has a radius of 14 m and a height of 6 m
We need to find the exact volume of the cylinder.
The formula to determine the volume of the cylinder is given by
[tex]Volume=\pi r^{2} h[/tex]
Let us substitute [tex]r=14[/tex] and [tex]h=6[/tex] in the above formula, we have,
[tex]Volume=\pi (14)^{2} (6)[/tex]
Squaring the terms, we get,
[tex]Volume=\pi (196)(6)[/tex]
Multiplying we have,
[tex]Volume=1176\pi \ m^3[/tex]
Thus, the volume of the cylinder is [tex]1176 \pi \ {m}^{3}[/tex]
Therefore, Option D is the correct answer.

Of the 250 cats in a local cat show, 73 are orange, 11 are white, 80 are black, 27 are calico, 50 are gray, and 9 are tuxedo. To the nearest thousandth, what is the probability a
randomly selected cat from the show will be gray or tuxedo?
Answer:
[tex]0.236[/tex]
Step-by-step explanation:
The total number of cats in a local cat show is 250
Of these, 73 are orange, 11 are white, 80 are black, 27 are calico, 50 are gray, and 9 are tuxedo.
The probability of a
randomly selected cat from the show will be gray or tuxedo is
[tex] = \frac{50}{250} + \frac{9}{250} [/tex]
We simplify to get:
[tex] = \frac{50 + 9}{250} [/tex]
[tex] = \frac{59}{250} [/tex]
[tex] = 0.236[/tex]
To find the probability of selecting a gray or tuxedo cat in a cat show, add the number of gray and tuxedo cats, then divide by the total number of cats.
The probability that a randomly selected cat from the show will be gray or tuxedo is calculated by adding the number of gray cats and tuxedo cats, then dividing by the total number of cats.
Number of gray cats = 50
Number of tuxedo cats = 9
Total number of gray or tuxedo cats = 50 + 9 = 59
Probability = Number of gray or tuxedo cats / Total number of cats
Probability = 59 / 250 ≈ 0.236

A. 4r = v
B. r + 4 = v
C. 4v = r
D. v + 4 = r
(as i noramlly say im terrible at math)
Answer:
A. 4r=v
Step-by-step explanation:
It says that she ate 4 times as many as Reagen and r represents the number that Reagen at so it would be 4r. While v represents how many Olivia ate which is 4r so 4r = v.
Answer:
A.4r = v
Step-by-step explanation:
Because is really asking for a ratio so the comparison of two objects
so if Olivia ate four times as much as Reagan then first start off by finding the variables which is R and V .R is how much Reagan ate well we know she at 4 times more than Olivia so 4R and now you gotta figure V how much Olivia ate so 4R = V

Which statement below is true?
A. If p → q is true, then q → p is true.
B. If p → q is true and p is true, then q is true.
C. If p → q and q → r are true, then q → p is true.
D. If p → q and q → r are true, then r → p is true.
The correct statement is B. If p → q is true and p is true, then q is true.
Explanation:The correct statement is B. If p → q is true and p is true, then q is true.
This is known as the modus ponens rule and is a valid argument form in propositional logic. It states that if an implication is true and the antecedent (p) is true, then the consequent (q) must also be true.
For example, if p represents 'it is raining' and q represents 'the ground is wet', and the statement 'if it is raining, then the ground is wet' is true, and we know that it is indeed raining (p is true), then we can conclude that the ground is wet (q is true).

Which statements are true about the components of a circle? Check all that apply.
The radius is half the length of the diameter.
The circumferences is triple the radius.
The circumference is the perimeter of a circle.
To find the circumference, multiply it by the diameter.
The diameter is triple the length of the radius.
The radius of a circle is half the length of the diameter, and the circumference is the perimeter of the circle. However, the circumference is not triple the radius, and the diameter is not triple the length of the radius.
Explanation:In the context of Mathematics, particularly geometry, the following statements are indeed true about the components of a circle:
The radius is half the length of the diameter. This is because the radius of a circle is defined as the distance from the center of the circle to its edge, while the diameter is the distance across the circle passing through the center. The circumference is the perimeter of the circle. This perimeter is also called the circumference in the context of circles, as it is the length around the edge of the circle.However, the statements that the circumference is triple the radius, to find the circumference multiply it by the diameter, and the diameter is triple the length of the radius, are incorrect. The circumference of a circle is calculated as 2πr (two times the radius times Pi), and the diameter is twice the length of the radius, not triple.

How many more puppies weighed 3 pounds then 7 pounds?
Answer:
4 pounds?????
Step-by-step explanation:
(NOT QUITE SURE WHAT THE QUESTION WAS SO MAY BE WRONG)
7 - 3 = 4 pounds????
The answer depends on the number of puppies that weigh 3 pounds and 7 pounds. If 'x' puppies weigh 3 pounds and 'y' puppies weigh 7 pounds, the number of 3 pound puppies that outweighed the 7 pounds ones can be found by subtracting 'y' from 'x'.
Explanation:The phrasing of the question is a bit unclear. If we assume 'How many more puppies weighed 3 pounds than 7 pounds?' is the question, it's not possible to answer without the number of puppies that weigh 3 pounds and the number of puppies that weigh 7 pounds. Let's say you have 'x' puppies that weigh 3 pounds and 'y' puppies that weigh 7 pounds. The number of puppies that weigh more at 3 pounds than 7 pounds would be calculated as 'x' minus 'y'. If you have specific numbers to replace 'x' and 'y', substitute them in to find the number of puppies weighing more at 3 pounds.
