The way to find the area of a triangle is A=
if the base is 3 feet longer then the height we can write it like this B=H+3
now we can add it to our area equation
20=
20=
40=
+3H
10
=
h=3.2ft
Answer:
<em>Net price: $4972.50</em>
Step-by-step explanation:
<u>Percentages</u>
We know a ream of paper has a list price of $25.50. Custom Greetings placed an order for 300 of them. If they have purchased them at list price, the total price would have been
300*25.50=$7,650
But we also know there was a 35% trade discount, so the net price of their order is
$7,650-$7,650*35/100=$4972.50

Answer:
The area of triangle K is 16 times greater than the area of triangle J
Step-by-step explanation:
we know that
If Triangle K is a scaled version of Triangle J
then
Triangle K and Triangle J are similar
If two triangles are similar, then the ratio of its areas is equal to the scale factor squared
Let
z -----> the scale factor
Ak ------> the area of triangle K
Aj -----> the area of triangle J
so
we have
substitute
therefore
The area of triangle K is 16 times greater than the area of triangle J
Answer:
Step-by-step explanation:
Subtract 7 from both sides.
Simplify.
Divide both sides by 5.
Simplify.
