The ratio of a : b is 1 : 2
Step-by-step explanation:
A ratio is a relationship between two numbers indicating how many times the first number contains the second number
Ex: If there are eight oranges and six bananas, then the ratio of oranges to bananas is eight to six, and is written as 8 : 6, which is equivalent to the ratio 4 :3 in its simplest form
∵ a + b = 3a
- To find the ratio between a and b find b in terms of a
- Subtract a from both sides
∴ b = 2a
→ a : b
Substitute b by 2a
→ a : 2a
Divide both terms by a
→ 1 : 2
∴ a : b = 1 : 2
The ratio of a : b is 1 : 2

Sure. So we have -9x, and then we can distribute the negative, just as we would do with a number. That gives us -9x-17-7x. We can combine the -9x and -7x to get -16x. Therefore, our answer is -16x-17. Hope this helped!
Answer:
h=0.89
Step-by-step explanation:
Given
Diameter=22m
so radius=11m
Volume=113m^3
Solution
1/3πr^2h=113
1/3×3.14×11×11h=113
h=113×3/3.14×11×11
h=0.89
So the value of h is 0.89
Answer:
Lines are parallel.
Step-by-step explanation:
The given lines are
Rearrange the equation in the slope intercept form that is
where
is the slope.
<em>First Line:</em>

compare it with 
slope (
) of first line 
<em>Second Line:</em>

divide both by 

compare it with 
slope
of second line 
Since slope of two lines are equal

hence these lines are parallel.
Answer:
17.03 units
Step-by-step explanation:
The distance formula for the distance between two points (x1, y1) and (x2, y2) is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
For the given points, the distance is ...
d = √((8-(-3))^2 +(-6-7)^2) = √(11^2 +(-13)^2)
d = √(121 +169) = √290
d ≈ 17.03
The distance between the points is about 17.03 units.
