The scale from the drawing means ...
... drawing size : life size = 3 : 1000
This can be turned around to get ...
... life size : drawing size = 1000 : 3
I find this form more convenient to use in a proportion:
... actual length / drawing length = 1000 / 3
Multiplying by "drawing length", we get ...
... actual length = (drawing length)·(1000/3)
This will be true for both drawing lengths.
_____
... Pool length = (15 cm)·1000/3 = 5000 cm = 50 m
... Pool width = (7.5 cm)·(1000/3) = 2500 cm = 25 m
The area is the product of these dimensions:
... pool area = (50 m)·(25 m) = 1250 m²
Answer:
a1=1/2
r=3/4
n=5
Step-by-step explanation:
a1 is the first term in the geometric series
a1=1/2
r is the common ratio of the first and second term
r=(3/8)/(1/2)
r=3/4
where n is the no of the term in the geometric series
In algebra, the polynomial remainder theorem or little Bézout's theorem is an application of Euclidean division of polynomials. It expresses that the rest of the division of a polynomial by a direct polynomial is equivalent to. Specifically, is a divisor of if and just if a property known as the factor hypothesis.
The number multiplied at each stage of a geometric sequence is called its common ratio.
X = 5 and y = -12 is in the fourth quadrant. Hypotenuse = 13
sin theta = opposite / hypotenuse = -12 /13
A secant is a line that intersects a circle in exactly two points. When a tangent and a secant, two secants, or two tangents intersect outside a circle than the measure of the angle is formed is one-half the positive difference of the measures of the intercepted arcs.
