Answer:its Graph C
(According to the law of Nicoloas Sadi Carnot)
1. The model is <span>14x19x11 centimeters. The ratio is 1 cm : 0.5 m.
14(0.5) = 7
19(0.5) = 9.5
11(0.5) = 5.5
</span>7x9.5x5.5 meters
b) 365.75 m^3
2. To find the money spent on food, all you do is find the percent of food of the total income. food = 35%, income = $2000
35% of 2000
0.35(2000)
a) $700
3. <span>4.8x-1.3=1.7
First add 1.3 to both sides to cancel it out.
4.8x = 3
Divide both sides by 4.8.
x = 0.625
</span><span>c) 0.63</span>
Answer:
75π
≈ 235.62 
Step-by-step explanation:
R represents the radius of the lawn
r represents the area of the circular bed
So,
Area of the remaining lawn, A = area of the lawn - area of the circular flower bed
A = πR^2 - π^2
A = π(R^2 - r^2)
A = π(10^2 - 5^2)
A = π( 100 - 25)
A = 75π
≈ 235.62
