I take it that we are to assume that the ratio between the actual length and the shadow length are directly proportional
so therefor we set up the following proprtion
actual height: shadow height=40ft:16ft
we are given that the tree is actually 27ft
so
40ft:16ft=27ft:?ft
make into a fraction
40ft/16ft=27ft/?ft
cross multiply or multiply both sides by 16?ft²
40?ft²=432ft²
divide both sides by 40ft
?ft=10.8ft
the length of the shadow is therfore 10.8ft
The painting's original price was $3,500.
Step-by-step explanation:
Step 1:
The price now is $500 lesser than 3 times the original price. So
The current selling price = (3 × original price) - $500.
If the current selling price is y and the original price is x, then
Step 2:
For this question, we have 
. Substituting this in the equation, we get
So the original price of the classic painting was $3,500.
Answer should be C. If you simplify the vertex equation y=7(x+1)^2 -3, you end up with the standard equation.
y=7(x^2 + 2x + 1) -3
y= 7x^2 + 14x + 7 - 3
y= 7x^2 + 14x + 4
Answer:
Division
Step-by-step explanation:
to get the value of X you have to divide both sides by 6
6x=-25
x=-25/6
