Answer:
The answer to your question is:
Step-by-step explanation:
Q1. They are vertical angles, so they measure the same
[2(x + 10)] = (3x - 30)
2x + 20 = 3x -30
2x - 3x = -30 - 20
- x = - 50
x = 50
Q2. They are also vertical angles, so they measure the same.
[6(x - 2)] = 3x + 30
6x - 12 = 3x + 30
6x - 3x = 30 + 12
3x = 42
x = 42/3
x = 14
∠DHG = 6(14 - 2)
∠DHG = 6(12)
∠DHG = 72
Answer:
c. 25.12
this can just be estimated- 8 x pi- or, to make it easy just do 8 x 3= 24. that gets you in the ballpark, and the only answer close is C
Answer:
No, it only equals 1 3/4.
Step-by-step explanation:
You first need to break up 1/2. You should know it equals 2/4, so adding 1 1/4 and 2/4, it will equal 1 3/4
Formula for <span>Volume of cube= 1/3 x area of base x height
</span>as base and height are the same:
So,
Base = 18 cm
Height = 18 cm
Area of base = Base^2
<span>Area of base = 18^2
</span><span>Area of base = 324 cm
</span>Putting all the values into the formula:
1/3 x 324 x 18
<span>=6 x 324 </span>
= 1944 cm^3
So according to above explanation
<span>C) 1944 cm3, is the correct answer.</span>
