Answer:
smaller triangle area = 73 1/3 ft^2
Step-by-step explanation:
The smaller triangle has a ratio of linear dimensions of 10/15 = 2/3 of that of the larger triangle. The area ratio is the square of this, so the area of the smaller triangle is ...
(165 ft^2)(2/3)^2 = (165 ft^2)(4/9) = 220/3 ft^2 = 73 1/3 ft^2
Answer:
A
Step-by-step explanation:
The degree is cubic (3) and there are 3 terms X^3, X^2, X
1 Move all terms to one side.
{x}^{2}+15x+45=0
x
2
+15x+45=0
2 Use the Quadratic Formula.
x=\frac{-15+3\sqrt{5}}{2},\frac{-15-3\sqrt{5}}{2}
x=

There are 2 pints in 1 quart
You have, for example, 6 pt of liquid
Since there are 2 pints in 1 quart, divide 6 and 2 together to get the qt amount you have
6/2 = 3
You have 3 qts
C is your answer
hope this helps
