Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°
Answer:
<em>A = 70</em>
Step-by-step explanation:
<em>CB </em>is equal to <em>EZ </em>and <em>E </em>equals 35, and <em>E </em>and <em>C </em>are the same, therefore, both <em>E </em>equals 35. Since there's 180 degrees in a triangle, and <em>ABY </em>equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that <em>B </em>equals 75. You have to add <em>E </em>and <em>B</em> (35 + 75), since that's in the same triangle as <em>A. </em>When you do that, you get 110. Subtract 180 - 110 to get <em>A, </em>which is 70.
Answer: 1 / 5 of the total distance.
Step-by-step explanation:
They traveled 7/10 of the distance on Saturday. This means that on Saturday, the fraction left was:
= 1 - 7/10
= 3/10 of the distance
On Sunday, they traveled 2/3 of this remaining distance. The fraction of the distance traveled is therefore:
= 2/3 * 3/10
= 6 / 30
= 1 / 5 of the total distance.
Answer:
k = 0
Step-by-step explanation:
<u>Explanation</u>:-
given straight line equation is k x+(k+1)y=2......(1)
The point A(2,2) lies on the equation is
substitute x = 2 and y=2
k(2) + (k+1)(2) =2
now simplify 2 k+2 k+2 = 2
subtracting '2' on both sides , we get solution is
4 k +2 -2 = 2-2
4 k =0
k = 0
7.6*10^3+2.3*10^5=7600+230000= 237600.
