Since the architect wants similar figures, it comes from the definition of similar triangles that the ratio of corresponding sides (all 3 sides) should be equal.
So,
.
Let's find CB.

So, CB should be 8. Option C is correct.
ANSWER: Change the length of side CB to 8 feet
The angles of a triangle all add up to 180º.
You need to set up and solve the equation:
84+48+3h = 180
Answer:
Y = 3/4x - 2
Step-by-step explanation:
Slope = (1 - - 5)/(4 - - 4 =6/8 = 3/4
b = -5 - (3/4)(-4)
b = -5 + 3 = -2
y = 3/4x - 2
1 liter of petrol in London costs £1.029
Since 1 gallon consist of 3.7854 liters, the cost of 3.7854 liters is calculated as:
Cost of 1 gallon of petrol in London = 3.7854*1.029 =£3.8951766
Next, we convert the pounds (£) to dollar($)
Since the exchange rate is 1$ =£ 0.497
£3.8951766 in $ = £3.8951766/£ 0.497 = 7.837$
The price of London petrol in dollars ($) per gallon =$7.84 (Rounded to nearest cents)
The answer is 1,695.6 in³.
The volume of the empty space is the difference of the bigger cylinder and the smaller cylinder: V = V1 - V2
The volume of the bigger cylinder is:
V1 = π r² h
r = 10 in
h = 15 in
π = 3.14
V1 = 3.14 * 10² * 15 = 4,710 in³
The volume of the smaller cylinder is:
V2 = π r² h
r = 8 in
h = 15 in
π = 3.14
V2 = 3.14 * 8² * 15 = 3,014.4 in³
The volume of the empty space is:
V = V1 - V2 = 4,710 in³ - 3,014.4 in³ = 1,695.6 in³
