You have to use the Pythagorean theorem a squared plus b squared is c squared so 13 squared plus 18 squared equals c squared. 13x13=169 18x18=324 169+324=493 so c squared is 493 to get c you square root 493 which equals 22.2 so the diagonal, c, is 22.2 centimeters long
Answer:
20%
Step-by-step explanation:
To find out the percent decrease of the price of the lotion, the first step is to get the amount of the decrease in price.
The lotion is normally $3.00 for the bottle.
This week, it's at $2.40 for the same bottle.
The difference is then of $0.60 per bottle.
Now, we take that $0.60 and we divide it by the original price of $3, we get:
$0.60 / $3.00 = 0.20
So the special is a reduction of 20% from the original price of $3.00 per bottle.
Answer:
5
Step-by-step explanation:
So let's start with making an equation,
125 x A = 625 Note: A is just a variable for the missing number
125A / 125 = 625 / A
A = 5
So, the missing number is 5

The conversion rate US dollars to Euros is represented with the function:
E(n)=0.72n
n- number of dollars
E(n) - Euros as a function of US dollars
The conversion rate Euros to Dirhams is :
D(x)=5.10x
x- number of Euros
D(x)- Dirhams as a function of Euros
<span>We are trying to find D(x) in terms of n.
D(x) = 5.10x
x can be rewritten as E(n)
D(x) = 5.10(E(n))
D(x) = 5.10(E(n))
D(x) = 5.10(0.72n)
D(x) = 3.672n </span>
According to this the following statement is true:
A) <span>(D x E)(n) = 5.10(0.72n)</span>
Answer:
The coordinates of C and D are (1, 3) and (-5, 1), respectivelly.
Step-by-step explanation:
Since E is the midpoint of diagonals AD and BC (see attachment). That is:
The vectorial distances of AE and BE are, respectively:
Now, the relative vectorial distances to C and D are now obtained:
Lastly, the coordinates are found by the following vectorial equations:
The coordinates of C and D are (1, 3) and (-5, 1), respectivelly.
