The slope of the equation is 1/2.
1) 2a = 9b ⇒ 2:9
2) a + b = 3b ⇒ a = 2b ⇒ 1:2
Answers: 2:9 and 1:2
This question is incomplete but if you are asking for the angle measure then sin (10) is 0.1736481777
Answer:
125 traffic cones
Step-by-step explanation:
In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:
, where 'x' is the number of meters
cross-multiply: x = 25(50) or x = 1250 m
Since there is a cone every 10 m, we can divide the total number of meters by 10:
1250/10 = 125 cones
Answer:
44(2t-35)
Step-by-step explanation:
First, regroup terms
(2t-35)(45-1)
Then simplify 45-1 to 44
(2t-35)(44)
Now regroup terms again
44(2t-35)
