Answer:
The formula is connecting R and A
[tex]R = k \frac{1}{A}[/tex]
The value of 'K' = 18.15
Step-by-step explanation:
Step(i):-
Given that R is inversely proportional to A
R ∝ 1 / A
[tex]R = k \frac{1}{A}[/tex]
Given R = 12 .1 and A = 1.5
[tex]R = k \frac{1}{A}[/tex]
[tex]12.1 = K (\frac{1}{1.5} )[/tex]
K = 12.1 × 1.5
K = 18.15
The value of 'K' = 18.15
write this rate as a unit rate 1/7 1/14

Answer:
The answer is 2.
Step-by-step explanation:
First you have to change 1/7 divided by 1/14 like this: 1/7 times 14/1.
Second solve the equation, 1/7 x 14/1 = 14/7 = 2.

If interest is compounded semi-annually, which expression
represents the account balance in t years?
Answer:
The equation to represent the account balance in t years
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{2t}[/tex]
Step-by-step explanation:
Given the compound interest equation
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
here
A represents Accrued Amount (principal + interest)
P represents Principal Amount
I represent Interest Amount
r represents the Annual interest rate
t represents Time Involved in years
n represents the number of compounding periods per unit t
As we are given that the interest is compounded semi-annually
i.e. n = 2
so substituting n = 2 in the equation
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{2t}[/tex] ∵ n = 2
Thus, the equation to represent the account balance in t years
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{2t}[/tex]
Esther and her 6 brothers went shopping at the mall. She shopped in 12 different stores while her brothers each shopped in 8 different stores. How many stores did Esther and her brothers shop in altogether?
Answer:
60 stores
Step-by-step explanation:
Here, we want to get the total number of stores in which Esther and her 6 brothers went shopping
From the question, she shopped in 12 different stores
Each of her six brothers shopped in 8 different stores
That makes the number of stores in which the brothers shop be 8 * 6 = 48 stores
The total number of stores is thus, 48 + 12 = 60 stores
7. This year, the water in a reservoir dropped by 60%. For the original water level to be restored next year, by what percent must the remaining reserves increase?
Answer:
Given: Water in a reservoir dropped by 60%
Step-by-step explanation:
let the total water level of reservoir be 100.
then, in first year
the water reservoir dropped = 60% of 100
=[tex]\frac{60}{100}[/tex] * 100
= 60
therefore, total water level needed to be restored till next year= 100
remaining water level to restore till next year= 100-60
=40
percentage= [tex]\frac{40}{100}[/tex] * 100
=40%

Luke wants to reduce the area of his rectangular garden by one-fourth. The expression 1/4 lw can be used to represent this change. What is another way to write this expression?
Answer:
lw/4
Step-by-step explanation:
Area of a rectangle = length × width
= l × w
Area of a rectangle = let
reduce the area of his rectangular garden by one-fourth
= 1/4 * lw
= 1/4lw
What is another way to write this expression?
Another way to write the expression is
= 1/4 * lw
= lw / 4
If f(x) = -x + 5 and g(x) = x^2, what is (g° (-1)?
Answer:
[tex](g\circ f)(-1)=36[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=-x+5\text{ and } g(x)=x^2[/tex]
And we want to find:
[tex](g\circ f)(-1)[/tex]
This is equivalent to:
[tex]=g(f(-1))[/tex]
So, evaluating f(-1) first, we acquire:
[tex]f(-1)=-(-1)+5=6[/tex]
Then by substitution:
[tex]=g(6)[/tex]
So:
[tex]=(6)^2=36[/tex]
Therefore:
[tex](g\circ f)(-1)=36[/tex]
Your answer is indeed correct.
Answer:
please refer to the above attachment.

What is the apparent solution to the system of equations?
y = -2 +2
y=40 +7
Graph the system of equations using the Line tool. Plot a point at the apparent solution to the system using the point tool.
Answer:
y=−x+2y=4x+7 NO
y=−x+2 YES
y=4x+7
Multiply the first equation by 4, obtaining: 4y = -4x + 8
Add the 2nd equation to this result: y = 4x + 7
--------------------
5y = 15, and y = 3
Then, using the first equation, determine x:
y = 3 = -x + 2
1 = -x, so x = -1
The solution is (-1, 3)
Answer: (-1; 3)
Step-by-step explanation:
y = -x + 2
y = 4x + 7
4x + 7 = -x + 2
4x + 7 + x - 7 = - x + 2 + x - 7
5x = - 5
x = - 1
y = 4(-1) + 7
y = 3
Intersection point: (-1; 3)

A rectangle made of squares is shown . The length of the side of each square is 1 cm create an equation to find the area of the rectangle. Move numbers an symbols to the lines
Answer:
See Explanation
Step-by-step explanation:
The rectangle is not shown. To solve this question, I'll make use of the attachment.
Apply the same steps, and you'll get the answer to your question.
From the attachment, we have:
[tex]Rows = 3[/tex]
[tex]Columns = 4[/tex]
Since the length of each square is 1 cm, then
[tex]Row = 3cm[/tex]
[tex]Column = 4cm[/tex]
So, the area is:
[tex]Area = Row * Column[/tex]
[tex]Area = 3cm * 4cm[/tex]
[tex]Area = 12cm^2[/tex]

Can anybody help please I’ll mark brainlist!
Can anybody answer this question??
The answer is A
as the x+ 4 is when we replace x with 0
x=0
so
y=0+4
=4
So the line of y must intersect at (0,4) coordinate
which is given as in A and should be a positive slope

renting a bike and the total amount spent to rent the bike? (5 points)
Answer:
Neither of the graphs show a proportional relationship.
Step-by-step explanation:
A proportional relationship is also known as a linear relationship, where when the points are plotted on the graph, the points increase or decrease at a constant rate. This will appear as a straight line with NO change.

Shelley delivered 10 newspapers after 20 minutes and 30 newspapers after 60 minutes what is rate of change that represents how many paper shelley's delivering every minute
Answer:
1 newspaper per 2 minutes
Step-by-step explanation:
If you look at 10 newspapers per 20 minutes, you can divide newspapers by minutes which gives you 10/20 = 1 newspaper per 2 minutes. To check the answer, you can do 2*30=60 since 2 minutes per each newspaper would equal 60 minutes.
Hope this helps!
