Answer: 32.35 cm^2
Step by step:
Find the area of the rectangle first.
A= L • W
A= 11 • 4.2
A= 46.2 cm^2
Then find the area of the circle. The formula is A= pi (r)^2. The diameter of the circle is 4.2 cm because looking at the width of the rectangle it fits into the circle as well.
Half of the diameter is 2.1 cm which is the radius.
A= pi (r)^2
A= pi (2.1)^2
A= pi (4.41)
A= 13.85 cm^2
Then you would subtract 13.85 from 46.2 to find the shaded portion.
Hope this helps :))
Assuming that the two investments are X & Y
X + Y = 6300
X = 6300 - Y (1)
9/100X + 4/100 Y = 372 (2)
replacing X from (1) into (2)
9/100(6300-Y) + 4/100 Y = 372
567 - 9/100Y +4/100Y = 372
(-9+4)/100Y = 372 - 567
5/100Y = -195
Y = 100*195/5 = 3900
From (1) we can get X
X = 6300 - 3900 = 2400
I hope this is helpful
The only way to do that is with +7 and -7 .
Answer:
180 houses
Step-by-step explanation:
The 3 part of the ratio 10 : 3 represents 30 bungalows, thus
30 ÷ 3 = 10 ← value of 1 part of the ratio
10 parts = 10 × 10 = 100 ← number of flats
The 5 part of the ratio 9 : 5 represents 100 flats, thus
100 ÷ 5 = 20 ← value of 1 part of the ratio, then
9 parts = 9 × 20 = 180 ← number of houses
