Answer:
875 ft²
Step-by-step explanation:
Given 2 similar rectangles with ratio of sides = a : b, then
ratio of areas = a² : b²
Here the ratio of sides = 5 : 25 = 1 : 5, thus
ratio of areas = 1² : 5² = 1 : 25
Thus the area of EFGH is 25 times the area of ABCD
area of EFGH = 35 × 25 = 875 ft²
Answer:
SOH-CAH-TOA
= 40.60°
SOH = SIN = OPP/HYP
SIN(Θ) = 6/
Step-by-step explanation:
Suppose you add x liters of pure water to the 10 L of 25% acid solution. The new solution's volume is x + 10 L. Each L of pure water contributes no acid, while the starting solution contains 2.5 L of acid. So in the new solution, you end up with a concentration of (2.5 L)/(x + 10 L), and you want this concentration to be 10%. So we have

and so you would need to add 15 L of pure water to get the desired concentration of acid.
Answer:
A rhombus is quadrilateral with all side of equal length. Thus a quadrilateral with all sides of equal length and all angles right angles is still a rhombus but it is also a square. It is also a quadrilateral, a rectangle and a parallelogram.

I hope this helped! have a great day! :)
Answer:
y + 7 = -
(x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
Where m is the slope and (a, b) a point on the line
Here m = -
and (a, b) = (1, - 7), thus
y - (- 7) = -
(x - 1), that is
y + 7 = -
(x - 1) ← in point- slope form
