Answer: 16 square units</h3>
Let x be the height of the parallelogram. Right now it's unknown, but we can solve for it using the pythagorean theorem. Focus on the right triangle. It has legs a = 3 and b = x, with hypotenuse c = 5
a^2 + b^2 = c^2
3^2 + x^2 = 5^2
9 + x^2 = 25
x^2 = 25-9
x^2 = 16
x = sqrt(16)
x = 4
This is a 3-4-5 right triangle.
The height of the parallelogram is 4 units.
We have enough info to find the area of the parallelogram
Area of parallelogram = base*height
Area of parallelogram = 4*4
Area of parallelogram = 16 square units
Coincidentally, the base and height are the same, which isn't always going to be the case. The base is visually shown as the '4' in the diagram. The height is the dashed line, which also happens to be 4 units long.
Answer: <em>ok so if 60% is under 25 then we can assume 40% is over 25, and then do 40% of 450,000, which is 180,000 .</em>
<em>so we can say that 180,000 people in the town are over 25 years old</em>
Answer:
Volume = 308
Step-by-step explanation:
Volume of a rectangular prism = Height * Width * Depth
Sub in the three values and solve
V = 11 * 7 * 4
V = 308
Answer:
EF ≈ 1.98
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° = 
= 
= 
( multiply both sides by 4.5 )
4.5 × sin26° = EF
4.5 × 0.44 = EF , that is
EF ≈ 1.98 ( to 2 dec. places )
P^5 / P^2
The base are equal, so we should to subtracting the powers only
Dividing exponential expressions
P^5 / P^2 = P^(5-2)
:. = P^3
