Answer:
x=180-(76+63)=41 degrees that is option 4
Step-by-step explanation:
Linear pair
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>
10.
a) x- is the time after which the total cost is the same.
24 + 99x - is the cost in the dealership
45 + 89x is the cost at the local mechanic
24 +99x = 45 + 89x
99x - 89x = 45 - 24
10x = 21
x= 2.1 (hours)
b) 24 +99x < 45 + 89x
x< 2.1
The repairs cost less in dealership when work takes less than 2.1, and the dealership is better, because the cost of parts is less in the dealership.
Answer: 70
plz give brainliest
Step-by-step explanation:
Solution:
Since
96 : 160 = 42 : X
Then we know
160/96 = X/42
Multiplying both sides by 42 cancels on the right
42 × (160/96) = (X/42) × 42
42 × (160/96) = X
Then solving for X
X = 42 × (160/96)
X = 70
Therefore
96 : 160 = 42 : 70
