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

Another way to write the expression is
= 1/4 * lw
= lw / 4
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%
Anyone know the answer?!

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.

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]

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.

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]

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

A store manager and stroke some new trainees that a book is priced at $21 winds up costing a customer $20.63 what does the tax is included which is the sale tax percentage
Answer:
1.76%
Step-by-step explanation:
Given
Original price of the book = $21
Price after sales percentage = $20.63
Discount = 21-20.63
Discount = $0.37
sale tax percentage = discount/original price × 100%
sale tax percentage = 0.37/21 × 100
sale tax percentage = 37/21
sale tax percentage = 1.76%
Hence the sale tax percentage is 1.76%
