Answer:
t = total people
m = men
w = women
w / m = 3 So A) w = 3 * m
B) w = m + 200
multiplying A) by minus 1
A) -w = -3m
B) w = m + 200
Adding the 2 equations
0 = -2m + 200
2m = 200
m = 100 Since there are 200 more women than men then there are
300 women
Total people = 100 + 300 = 400
Step-by-step explanation:
R = _/A/4pi. where that sign before A is square root and pi means pie
Answer:
Rectangle B is a scaled copy of rectangle A.
Enlargement scale factor = 1.25
Step-by-step explanation:
<u>Rectangle A:</u>
Length = 12 units
Width = 8 units
<u>Rectangle B:</u>
Length = 15 units
Width = 10 units
<u>Rectangle C:</u>
Length = 30 units
Width = 15 units
Rectangle B length ÷ rectangle A length = rectangle B width ÷ rectangle A width = 1.25
i.e
=
= 1.25
Hence rectangle B is a scaled copy of rectangle A and the scale factor of enlargement is 1.25
