Answers
Answer:
Step-by-step explanation:
Answer in the photo
A sphere that has a volume 0.288π inches cube has a radius of 0.6 inches
Volume of a sphere
The volume of a sphere is described as follows:
volume of sphere = 4 / 3 πr³
where
r = radius of the sphereTherefore,
volume = 0.288π inches cube
Hence, the radius can be calculated as follows;
0.288π = 4 / 3 πr³
divide both side by π
0.288 = 4 / 3r³
cross multiply
0.288 × 3 = 4r³
0.864 = 4r³
divide both sides by 4
r³ = 0.864 / 4
r = ∛0.216
r = 0.6 inches
Therefore, a sphere that has a volume 0.288π inches cube has a radius of 0.6 inches

If x = time, and y = the number of problems in the set, which equation models the relationship?
Question 3 options:
y = 12x
y = x + 12
y = 1.2x
y = x + 1.2
Answers
Answer:
C, y = 1.2x
Step-by-step explanation:
Notice that x, representing time, is multiplied by 1.2 each time to get y, representing the number of problems. You can find this out by dividing y by x. 36/30 = 1.2.
48/40 = 1.2.
And so on...
P.S.: If you ever come across a problem like this, subtract one y value by another y value, then subtract the corresponding x values from eachother, then make both numbers into one fraction with y as the numerator and x as the denominator. In this problem, that would look like this:
48 and 36 are both y values: 48 - 36 = 12
40 and 30 are the corresponding x values: 40 - 30 = 10
We get 12/10, which can be simplified to 1.2. The slope is 1.2.
This method will always work for a straight line and will be taught to you soon if you haven't learned it already.

Please select the best answer from the choices provided
Answers
Answer:
d. 7.3
Step-by-step explanation:
-16-10.2g = -14.7g + 16.85
4.5g = 32.85
g = 7.3
The solution for the equation -16 - 10.2g = -14.7g + 16.85 is g = 7.3. You can verify it by substituting the solution back into the original equation.
Explanation:To solve the given equation, -16 - 10.2g = -14.7g + 16.85, we must first isolate the variable, g, by moving all terms involving g to one side of the equation and constant terms to the other side. Add 10.2g to both sides of the equation, giving, -16 = -4.5g + 16.85. To further isolate g, subtract 16.85 from both sides resulting in -32.85 = -4.5g. Finally, divide by -4.5 to solve for g. Thus, g = -32.85 / -4.5 = 7.3. We verify our solution by substituting 7.3 back into the original equation and confirming that the equality holds true.

Answers
Answer:
see below
Step-by-step explanation:
We need to find the diameter of the square
We can find this using the Pythagorean theorem
a^2+b^2 = c^2 where the legs are 7 and 7 and the diameter is c
7^2 +7^2 = c^2
49+49 = c^2
98 = c^2
Taking the square root of each side
sqrt(98) = sqrt(c^2)
9.899494937 = c
Since 9.9 is less than 11 which is the diameter of the circle it will never touch the circle.
Since the longest part of the square is less than the diameter of the circle, the square will fit inside the circle without touching
Answer:
Diagonal < Diameter
Step-by-step explanation:
The square will fit inside without touching if the diagonal length is less than the diameter
Diagonal = sqrt(7² + 7²)
7sqrt(2)
Diameter = 11
7sqrt(2) < 11
Because
(7sqrt(2))² < 11²
98 < 121

Manuela and Stephen survey 250 people at a sporting event and ask if they prefer hamburgers or hot dogs, and if they prefer regular or diet soda.
Regular Soda Diet Soda Total
Hamburgers 90 40 130
Hot Dogs 70 50 120
Total 160 90 250
a. What is the probability that someone who prefers diet soda will also prefer hamburgers?
b. What is the probability that someone who prefers hot dogs will also prefer regular soda?
c. Are preferring diet soda and preferring hamburgers independent events? Explain.
d. Are preferring regular soda and preferring hot dogs independent events? Explain.
Answers
Answer:
a. 40/250
b. 70/250
c. Preferring diet soda and preferring hamburgers are not independent events
d. Preferring regular soda and preferring hot dogs are not independent events
Step-by-step explanation:
We are given:
Regular Soda Diet Soda Total
Hamburgers 90 40 130
Hot Dogs 70 50 120
Total 160 90 250
a. The probability that someone who prefers diet soda will also prefer hamburgers can be calculated as:
No. of people who prefer hamburgers and diet soda / Total no. of people
40/250
b. The probability that someone who prefers hot dogs will also prefer regular soda can be calculated as:
No. of people who prefer hot dogs and regular soda/Total no. of people
70/250
c. For two events to be independent, they must fulfill the condition:
P(A and B) = P(A) * P(B)
P(Diet Soda) = No. of people who prefer diet soda/total no. of people
= 90/250
P(Hamburgers) = No. of people who prefer hamburgers/total no. of people
= 130/250
P(Diet Soda and Hamburgers) = 40/250
Now, we need to check:
P(Diet Soda and Hamburgers) = P(Diet Soda) * P(Hamburgers)
40/250 = 90/250 * 130/250
40/250 ≠ 11700/62500
So, we can conclude that these two events are not independent events.
d. P(Regular Soda) = No. of people who prefer regular soda/total no. of people
= 160/250
P(Hot dogs) = No. of people who prefer hot dogs/total no. of people
= 120/250
P(Regular Soda and Hot Dogs) = 70/250
Now, we need to check if:
P(Regular Soda and Hot Dogs) = P(Regular Soda) * P(Hot dogs)
70/250 ≠ 160/250 * 120/250
So, these two events are not independent.
The solutions obtained are Part (a): The probability is 0.444, Part (b): The probability is 0.583, Part (c): Preferring diet soda and preferring hamburgers are not independent and Part (d): Preferring regular soda and preferring hot dogs are not independent.
Probability and Independence Analysis
Let's analyze the data provided from Manuela and Stephen's survey:
Regular Soda Diet Soda Total
Hamburgers 90 40 130
Hot Dogs 70 50 120
Total 160 90 250
→ Part A: Probability that Someone Who Prefers Diet Soda Also Prefers Hamburgers
The number of people who prefer diet soda is 90, and among them, 40 prefer hamburgers. Therefore, the probability is calculated as follows:
P(Hamburgers|Diet Soda) = 40 / 90
≈ 0.444
→ Part B: Probability that Someone Who Prefers Hot Dogs Also Prefers Regular Soda
The number of people who prefer hot dogs is 120, and among them, 70 prefer regular soda. Therefore, the probability is:
P(Regular Soda|Hot Dogs) = 70 / 120
≈ 0.583
→ Part C: Independence of Preferring Diet Soda and Preferring Hamburgers
To determine if these events are independent, we check if:
P(Diet Soda AND Hamburgers) = P(Diet Soda) * P(Hamburgers)
Calculations:
→ P(Diet Soda AND Hamburgers) = 40 / 250
→ P(Diet Soda) = 90 / 250
→ P(Hamburgers) = 130 / 250
→ P(Diet Soda AND Hamburgers) ≠ P(Diet Soda) * P(Hamburgers)
Since the equality does not hold, these events are not independent.
Part D: Independence of Preferring Regular Soda and Preferring Hot Dogs
We test the same independence condition for regular soda and hot dogs:
→ P(Regular Soda AND Hot Dogs) = P(Regular Soda) * P(Hot Dogs)
Calculations:
→ P(Regular Soda AND Hot Dogs) = 70 / 250
→ P(Regular Soda) = 160 / 250
→ P(Hot Dogs) = 120 / 250
→ P(Regular Soda AND Hot Dogs) ≠ P(Regular Soda) * P(Hot Dogs)
Therefore, these events are also not independent.

Step-by-step explanation:
We can use the Pythagorean theorem with legs 3x and 4x+7
a^2+ b^2 = c^2
(3x^2) +(4x+7)^2 = c^2
Let x = 8
(3*8)^2 + (4*8+7)^2 = c^2
24^2+ 39^2 = c^2
576+1521 = c^2
2097 = c^2
Take the square root of each side
sqrt(2097) = sqrt(c^2)
45.79301257 =c
Rounding to the nearest tenth
45.8 =c
Answer:
45.8
Step-by-step explanation:
First solve for the other two sides by replacing x with 8
4(8)+7 = 39
3(8) = 24
Then use the pythagorean theorem ([tex]a^{2} + b^{2} = c^{2}[/tex]) to solve for the hypotenuse, c being the hypotenuse
[tex]39^{2} + 24^{2} = c^{2}[/tex]

2097 = [tex]c^{2}[/tex]

Write the word sentence as an inequality. Then solve the inequality. Three less than a number x is more than 15. An inequality that represents this word sentence is..??? Please help me??
Answers
Answer:
x-3>15
x>18
Step-by-step explanation:
usually its better to read it from right to left, more than 15 tells you its gonna be >. then you see 3 less than x, which is x-3. Then solve as if the > was an equal sign
x-3>15
+3 +3
x>18
The inequality representing 'Three less than a number x is more than 15' is x - 3 > 15. Solving this, we get x > 18. Hence, x should be greater than 18.
The word sentence given is: 'Three less than a number x is more than 15'. To write this as an inequality, we start by identifying the mathematical phrase for 'Three less than a number x', which is 'x - 3'.
The phrase 'is more than' translates to the inequality symbol '>'.
Therefore, we set up the inequality as follows:
x - 3 > 15
Next, we solve the inequality step-by-step:
Start with the inequality: x - 3 > 15Add 3 to both sides to isolate x: x - 3 + 3 > 15 + 3This simplifies to: x > 18So, the solution to the inequality is x > 18.
In summary, when converting word sentences to inequalities, ensure you accurately translate the phrases and solve them step-by-step to find the solution.
