y is inversely proportional to x.
When y = 7, x= 9
Work out the value of y when x = 21.
Answer:
y = 3
Step-by-step explanation:
y is inversely proportional to x setup: y = k/x
'k' is the constant of variation; find this first
7 = k/9
k = 63
now use 'k' to find 'y'
y = 63/21
y = 3

What is parallelogram?A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
Given:
ABCD is a parallelogram.
And BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6.
The two diagonals bisect each other.
AC = AE + EC
AC = 2AE
AC = 8x-12
The diagonals of a parallelogram are equal.
So,
BD = AC
5x+3 = 8x-12
x = 3
So, AC = 12
Therefore, the AC is 12 unit.

The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Your friend wants to buy a pair of jeans that are on sale for 30% off if the jean's original price is $40.
Let "S" be the price of sales. Then the equation is given as,
30% = [($40 - S) / $40] x 100
0.30 = ($40 - S) / $40
S = $40 - $12
S = $28
The price of the pair of jeans that are on sale for 30% off will be $28.

Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply A. 160 shirts cost $20
B. 20 shirts cost $160
C. 20,160 shirts cost money
D. The total cost of shirts is 20,160
Answer:
option B is correct option.
Step-by-step explanation:
Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply
Looking at the graph we come to know that 20 shirts cost $160 because x -axis represent number of shirts and y-axis represent Total Cost
So, the point(20,160) means x = 20 and y=160
We have 20 shirts and the cost is $160
So, option B is correct option.

Elaine opened a savings account with a deposit of $1000. The interest on her account is compounded each year at a rate of 2%. Elaine will not make any additional deposits to or withdrawals from her account. What will be the balance in Elaine's account at the end of 3 years? Round your answer to the nearest whole dollar.
Answer:
$1,061.21
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Present value (PV) = $1,000
Rate of interest compounded yearly (r) = 2%
Time period (n) = 3
So, we can calculate the future value (FV) by using following formula,
Future Value = PV(1 + r)^n
By putting the value, we get
FV = $1,000 ( 1 + 0.02)^3
= $1,000 ( 1.02)^3
= $1,000 ( 1.061208)
= $1,061.21
