No. For example, the angles of every equilateral triangle ... whether its sides
are 1 nanometer, 1 inch, 1 mile, or 1 light-year long ... are always 60 degrees
each. The angles alone may reveal the <u>ratios</u> of the sides, but they tell nothing
about the actual length of any of the sides.
Answer:
The median is 83.
Step-by-step explanation:
A’(-8,-4) B’(4,-4) C’(4,8) D’(-8,8)
Because the scale factor is 4 all you do is multiply your coordinates by 4
Answer:
10,995.6 ft^3.
2300.3 gallons.
(both to the nearest tenth).
Step-by-step explanation:
Area of the surface of the river = area of the outer circle - area of the inner circle.
Radius of the outer circle = 30 *3 = 90 feet.
So the surface area of the river = π(90)^2 - π(85)^2
= 875π ft^2
Also the volume of the river = surface area * depth = 875π*4 = 3500π ft^3
= 10,995.6 ft^3.
Number of gallons of water it will hold = 10,995.6 / 4.78
= 2300.3 gallons.
The answer is :
c. (x+1)²=20
To check:
(x+1)²=20 (a+b)²=a²+2ab+b²
x²+2x+1=20
x²+2x=20-1
x²+2x=19
