Answer:
$1080
Data given:
selling price (SP): $1209.60
percentage profit: 12%
To calculate out percentage profit
profit% = gain/cost price × 100
gain = selling price - cost price
hence we have:
(1209.60 - cost price)/cost price ×100 = 12
when we cross multiply
we have 12costprice = (1209.60×100)-(100×cost price)
12CP=120960-100CP
collect like terms
12CP+100CP = 120960
112CP=120960
divide both sides by the coefficient of CP
CP = $1080
Step-by-step explanation:
Let x represent the missing side length.
By Pythagoras' Theorem,
We have x² + 12² = 13².
Therefore x² = 13² - 12² = 25 and x = 5.
(x = -5 is rejected as side lengths are positive)
Answer:


Step-by-step explanation:
Absolute Value Inequality entered :
|y+2|>6
Step by step solution :
Step 1: Rearrange this Absolute Value Inequality
Absolute value inequalitiy entered
|y+2| > 6
Step 2: Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |y+2|
For the Negative case we'll use -(y+2)
For the Positive case we'll use (y+2)
Step 3: Solve the Negative Case
-(y+2) > 6
Multiply
-y-2 > 6
Rearrange and Add up
-y > 8
Multiply both sides by (-1)
Remember to flip the inequality sign
y < -8
Which is the solution for the Negative Case
Step 4: Solve the Positive Case
(y+2) > 6
Rearrange and Add up
y > 4
Which is the solution for the Positive Case
Step 5:
Wrap up the solution
y < -8
y > 4

Answer:
∠DEC and ∠IHJ
Step-by-step explanation:
Alternate exterior angles are angles that lie on the outside of the parallel lines, but different sides.
∠DEC is on the upper left.
∠IHJ is on the lower right.
Therefore ∠DEC and ∠IHJ are alternate exterior angles.
So let's put it this way-
N% x 60 = 42
You want to isolate the variable
42/60 = N%
42/60 is .7 which is 70%
Hope this helps :)
