Which of the following quantities are inversely proportional? WILL GIVE BRAINIEST
a
The number of hours worked and the amount of money earned, assuming the worker is paid by the hour
Answer:
option 1
option 3
option 4
Step-by-step explanation:
Inversely proportional means "one quality increases, the other decreases " or "one quantity decreases ,other increases. " Inverse relantionship, that's it.
option 1:
Since the volume is given as 56 and we know the volume is area of base * height, to keep the volume at constant [56], if height increases, area of base would need to decrease, and vice versa. So Inversely proportional.
option 2:
The time spend in plowing a field with a tractor with increase when we area using more fuel.So more fuel used means more time spent. So these are directly proportional, Not inverse.
option 3:
Since the price is a constant, the amount of length we buy more,the price per one yard HAS to decrease, and vice versa. So ,this is Inverse relantionship.
option 4:
If the number of identical tractors. increase, it will take less time to plow the set 358 acre farm. And vice versa. So this is Inversely proportional as well.

Devin is collecting signatures for a petition to open a new park in her town. She needs to collect at least 1,000
signatures before she can schedule a meeting with the mayor. She already has 380 signatures. If each petition page
holds 80 signatures, which inequality best shows how many more pages (p) Devin needs?
Answer:
P = t - f
Step-by-step explanation:
First we need to find how many pages in total she needs so 1,000/80 - 12.5 so 13 pages. Then 380/80 4.75 of a page filled so subtract that from 12.5 to get 8 pages left to fill.
let p = pages left to fill
let T = total pages needed
let F = pages already filled
can someone do all the even numbers
Which situation can be represented by this equation?
170 +2.5x= 325 - 4x
Answer:
The second one is the answer.

Which statement correctly compares the function shown on this graph with
the function y = 2x - 5?
A. The function shown on the graph has a smaller rate of change and lower starting point.
B. The function shown on the graph has a smaller rate of change, but a higher starting point.
C. The function shown on the graph has a greater rate of change and a higher starting point.
D. The function shown on the graph has a greater rate of change, but a lower starting point.
The correct option is Option C: The function shown on the graph has a greater rate of change and a higher starting point.
What is the rate of change of function?The rate of change of function is the change in the value of the function with respect to x value.
rate of change of function f(x)= df(x)/dx= f'(x)
Here the function given in the question is y=2x-5
rate of change of function= f'(x)= df(x)/dx= dy/dx= d(2x-5)/dx= 2
the starting point of the function f is y-intercept of the function.
the y-intercept of the function is the point where the function touches the y-axis which can be calculated by putting x value is equals to 0.
y= 2x-5
⇒y= 2*0-5
⇒y= -5
The starting point of function is -5.
Given the graph has slope = |y-intercept| / |x intercept|
= 4/1 =4
rate of change of graph = slope of graph= 4
similarly, the y-intercept of the function is the point where the function touches the y-axis which can be calculated by putting x value is equals to 0.
The y-intercept of the graph= the starting point of the graph= -5
Therefore the function in the graph has a higher rate of change as well as a higher starting point.
From the above, it is clear that the correct option is Option C: The function shown on the graph has a greater rate of change and a higher starting point.

The domain of a function h(x) is x > 3, and the range is y2 -2. What are the domain and range of its inverse function, h-1(x)?
A. Domain: x>3 Range: y2 -2
B. Domain: x2 -2 Range: y> 3
C. Domain: x>-2 Range: y> 3
D. Domain: x2 3 Range: y> -2
Answer:
I think it's b I don't know for sure though
Step-by-step explanation:
I don't know for sure tho
Using inverse function concepts, the correct option is:
B. Domain: x < -2 Range: y> 3
--------------------------
The domain of a function is the set that contains all possible input values.The range of a function is the set that contains all possible output values.In the inverse function, input and output are exchanged, thus, domain and range are also exchanged.For the original function, the domain is x > 3 and the range is y < -2.Thus, for the inverse function, the domain is x < -2 and the range is y > 3, which means that option B is correct.A similar problem is given at https://brainly.com/question/24603090

3x= 5+7x solve for x
Answer:
x = -5/4
Step-by-step explanation:
3x= 5+7x (subtract 7x from both sides)
3x - 7x = 5
-4x = 5 (divide both sides by -4)
x = 5/(-4)
x = -5/4
In fig if x+y=w+z then prove that AOB is a line.
Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∘
∣ Angles around a point.
(x+y)+(w+z)=360
∘
(x+y)+(x+y)=360
∘
∣ Given x+y=w+z
2(x+y)=360
∘
(x+y)=180
∘
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line
6. Audrey's monthly car payment is $350 and
she needs to save at least $35 each month for
gas. If Audrey is paid $17.50 an hour, write
and solve an inequality to represent the
number of hours she must work in a month to
pay for her car payment and gas.
The number of hours she must work in a month to pay for her car payment and gas is 22 hours
What is inequality?inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
For one month, Audrey has to pay $350 for her payment and $35 for gas, meaning that she will need to pay $385 per month.
$350 + $35 = $385
Audrey makes $17.50 an hour. Set up equality to find the number of hours she must work to pay for her car payment and gas.
17.50x > 385
(17.50x)/17.50 > 385/17.50
x > 22
Therefore, Audrey must work at least 22 hours to pay for her car payment and gas.

hope this helps
Answer:
$5.40 for 12 letters
Step-by-step explanation:
you need to find the cost for 1 unit then multiply that by 12, so you take the cost (4.50) and divide it by letters (10) so you get 0.45. So that is the cost of q letter, then you that that unit rate and multi[ly it by the number that you need to figure out (12) so .45x12=5.40
12 letters=$5.40

Step-by-step explanation:
To simplify any square root;
Factorize the number under the root using prime numbersTake out the root any number repeated twice as one numberExamples:
1. Simplify [tex]\sqrt{8}[/tex]
factorize 8 using prime numbers
8 = 2 × 2 × 2, then [tex]\sqrt{8}=\sqrt{(2)(2)(2)}[/tex]
Take two of 2 out the root, then [tex]\sqrt{8}=2\sqrt{2}[/tex]
2. Simplify [tex]\sqrt{18}[/tex]
factorize 18 using prime numbers
18 = 2 × 3 × 3, then [tex]\sqrt{18}=\sqrt{(2)(3)(3)}[/tex]
Take the two 3 out the root, then [tex]\sqrt{18}=3\sqrt{2}[/tex]
Let us simplify [tex]3\sqrt{45}[/tex]
∵ 45 = 3 × 3 × 5
∴ [tex]3\sqrt{45}=3\sqrt{(3)(3)(5)}[/tex]
→ Take the two 3 out by one 3
∴ [tex]3\sqrt{45}=3(3)\sqrt{5}[/tex]
→ Multiply the numbers out the root
∴ [tex]3\sqrt{45}=9\sqrt{5}[/tex]
∴ The simplest radical form is [tex]9\sqrt{5}[/tex]
