Answer: D. About [tex]\frac{1}{2}[/tex] inches per hour.
Step-by-step explanation:
1. The city received [tex]12^{\frac{1}{4}}[/tex] inches of rain in [tex]25^{\frac{1}{2}}[/tex] hours.
2. Let's write the mixed number as decimal numbers:
[tex]12^{\frac{1}{4}}in=12.25in[/tex]
[tex]25^{\frac{1}{2}}h=25.5h[/tex]
3. To find the approximate rainfall rate in inches per hour, you must divide 12.25 inches by 25.5 hours, as following:
[tex]\frac{12.25in}{25.5h}=0.48\frac{in}{h}[/tex]
4. If you round the result to the nearest tenth, you obtain:
[tex]0.5\frac{in}{h}=\frac{1}{2}\frac{in}{h}[/tex]
5. Therefore, the answer is the option D.
The approximate rainfall rate is closest to 0.5 inches per hour therefore the correct answer is Option D.
To determine the approximate rainfall rate in inches per hour, we need to divide the total amount of rainfall by the duration over which it fell.
Total rainfall: [tex]12 \frac{1}{4}[/tex] inches (which is equal to 12.25 inches)Duration: 25 [tex]\frac{1}{2}[/tex] hours (which is equal to 25.5 hours)Using the formula for intensity:
Intensity (inches per hour) = Depth (inches) / Duration (hours)Intensity = 12.25 inches / 25.5 hours ≈ 0.48 inches per hourThe approximate rainfall rate is closest to 0.5 inches per hour, so the correct answer is Option D: about 1/2 inch per hour.
2x-1=3/4x +9 please help me solve
Hi!
[tex]2x-1=\frac{3}{4x+9}[/tex]
[tex]2x(4x+9)-1*(4x+9)=\frac{3}{4x+9}(4x+9)[/tex]
[tex]2x(4x+9)-(4x+9)=3[/tex]
[tex]2x(4x+9)-(4x+9)=3[/tex]
[tex]x=\frac{\sqrt{145-7} }{8},x=-\frac{7+\sqrt{145} }{8}[/tex]
[tex]x=\frac{\sqrt[]{145-7} }{8}, or x=-\frac{7+\sqrt{145} }{8}[/tex]
Explanation: First you had to multiply by 4x+9 from both sides. Then simplify, it gave us 2x(4x+9)-(4x+9)=3. Next you can also solve 2x(4x+9)-(4x+9)=3. And the answer it gave us is x=√145-7/8 or x=-7+√145/8 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie

Fuaad solved an absolute value inequality and expressed the solution as -12 < x > 7. What is another way to show Fuaad’s solution?
Solution: The another way to show the Fuaad's solution is [tex]x>7[/tex].
Explanation:
It is given that the solution of an inequality is [tex]-12<x>7[/tex].
It can be break in two parts [tex]-12<x[/tex] and [tex]x>7[/tex].
The inequality [tex]-12<x[/tex] means the values of x is greater than [tex]-12[/tex] and the inequality [tex]x>7[/tex] means the value of x is greater that than 7.
When we combine both results we get [tex]x>7[/tex] it means the value of x is greater than 7.
It can also represented by number line as shown in given figure.
The number line shows the values of x and red lines shows the solution of both inequalities [tex]-12<x[/tex] and [tex]x>7[/tex].
The common region shows the combination of both the possible inequalities, therefore the another way to show the Fuaad's solution is [tex]x>7[/tex].

I need help with a question before my test: how do I tell if a graph has rotational Symmetry if it is not an odd function and do all odd functions have point symmetry??
Answer:
If you know that the function is not odd, you know that the graph does not have rotational symmetry
Step-by-step explanation:
There is a theorem that says: "A function is odd if, and only if, its graph is symmetric with respect to the origin, or it has rotational symmetry in 180 ° with respect to the origin"
This statement is equivalent to:
If a function is odd, its graph has rotational symmetry with respect to the origin
If a graph has rotational symmetry with respect to the origin then the function is odd.
Therefore, it is impossible for the graph to have rotational symmetry with respect to the origin and the function is not odd.
Then, if you know that the function is not odd, you know that the graph does not have rotational symmetry
Evaluate the limit ....
It depends on how t is approaching 2.
In fact, if you consider the right limit, you have
[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{|t-2|} [/tex]
But since t is greater than 2, t-2 is positive, and thus |t-2| = t-2.
So, the limit becomes
[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{t-2} = \lim_{t \to 2^+} -1 = -1 [/tex]
On the other hand, if you consider the left limit, you have
[tex] \displaystyle \lim_{t \to 2^-} \dfrac{2-t}{|t-2|} [/tex]
But since t is less than 2, t-2 is negative, and thus |t-2| = -t+2.
So, the limit becomes
[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{-t+2} = \lim_{t \to 2^+} 1 = 1 [/tex]
So, this limit does not exist, because the left and right limits exist but are not the same.
Some people advise that in very cold weather, you should keep the gas tank in your car more than half full. Lou's car had 5.9 gallons in the 13-gallon tank on the coldest day of the year. Lou filled the tank with gas that cost $3.80 per gallon. How much did Lou spend on gas?
Lou spends the total amount would be $26.98 on gas which is determined by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
The following information is provided in the problem :
Lou topped up the tank with $3.80 per gallon of petrol.
Lou's car's 13-gallon tank held 5.9 gallons.
If he filled the tank, you can determine the total amount of money Lou spent by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.
So the total amount would be:
⇒ (13 - 5.9)(3.80)
⇒ (7.1)(3.80)
⇒ 26.98.
Therefore, the total amount would be $26.98

The gravitational attraction between two masses varies inversely as the square of the distance between them. If the attraction force between them is 75 lbs. when the bodies are eight feet apart, find the attraction when the masses are twelve feet apart.
a) 33 1/3 lbs. b) 50 lbs. c) 168 3/4 lbs.
Answer: Option a) 33 1/3 lbs
Solution:
Be
Attraction force (F) varies inversely as the square of the distance between them:
F=k/d^2
Constant of proportionality: k
Distance between the two masses: d
F=75 lbs when d=8 feet
Replacing in the formula above:
F=k/d^2
75 lbs=k/(8 feet)^2
Squaring in the denominator:
75 lbs=k/(64 feet^2)
Solving for k: Multiplying both sides of the equation by 64 feet^2:
(64 feet^2)(75 lbs)=(64 feet^2)[k/(64 feet^2)]
4,800 lbs*feet^2=k
k=4,800 lbs*feet^2
F=k/d^2
F=4,800 lbs*feet^2/d^2
Find the attraction when the masses are twelve feet apart:
F=?
d=12 feet
Replacing in the formula:
F=4,800 lbs*feet^2/(12 feet)^2
Squaring in the denominator:
F=4,800 lbs*feet^2 / (144 feet^2)
Dividing:
F=(4,800/48)/(144/48) lbs
F=100/3 lbs
F=(99+1)/3 lbs
F=(99/3+1/3) lbs
F=33 1/3 lbs
Final answer:
Using Newton's inverse square law for gravitational force, it is determined that the force of attraction will be a) 33 1/3 lbs when the distance between the masses is increased from 8 to 12 feet.
Explanation:
The scenario described falls under the gravitational force law stated by Isaac Newton, which is a fundamental concept in Physics. The force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them (F ∝ 1/d²). We are given that the gravitational attraction is 75 lbs when the bodies are 8 feet apart. To find the force at a distance of 12 feet, we use the inverse square law which indicates that increasing distance reduces gravitational force.
Let F1 be the initial force and d1 be the initial distance, and let F2 be the force at a new distance d2. According to the inverse square law, we have F1/F2 = (d2/d1)². Plugging in the values F1 = 75 lbs, d1 = 8 feet, and d2 = 12 feet, we get 75/F2 = (12/8)² = 2.25. Solving for F2, we find that F2 = 75 / 2.25 = 33.33 lbs.
Therefore, the gravitational attraction when the masses are twelve feet apart is 33 1/3 lbs.

each block in Ton’s neighborhood is 2/3 mile long if he walk 4 1/2 blocks how far does he walk?
if each block is 2/3 miles long, and he walks 4 1/2 blocks, we can simply multiply to two. It looks like this:
(2/3)(4 1/2)
to multiply, make 4 1/2 into an improper fraction and multiply normally
(2/3)(9/4)
Ton walks 3 miles total.
Final answer:
Ton walks a total distance of 3 miles if each block is 2/3 mile long and he walks 4 1/2 blocks by multiplying the length of one block by the number of blocks walked.
Explanation:
The question asks about the total distance Ton walks if each block in his neighborhood is 2/3 mile long and he walks 4 1/2 blocks. To find the total distance, we can multiply the length of one block by the number of blocks walked:
Convert 4 1/2 blocks to an improper fraction: 4 1/2 = 9/2 blocks.
Multiply the length of one block by the number of blocks: (2/3 mile/block) × (9/2 blocks) = (2×9) / (3×2) = 18 / 6 = 3 miles.
Therefore, Ton walks a total distance of 3 miles.
