Roman was studying the life of fish, frogs, and turtles in
Doyle Park. In two hours, he counted 4 more frogs than
turtles. The number of fish he counted was twice the
number of turtles. In total, he counted 68 animals. How
many fish were there?
how many frogs were there? how many turtles were there?
Answers
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish
identify the relationship between angles f, b, and a in the above diagram. PLEASE HELP WILL GIVE BRAINLIEST 7TH GRADE MATH
Answers
Answer:
Just remember that straight lines are always 180° (a + b = f)
Step-by-step explanation:
Assuming the triangle is equiangular and equilateral, a b and c are the same, so they are interchangeable.
f + c = 180 becuase it is a straight line. you can switch out c with a because they are the same. So:
f+a=180
(switch out with b)
f+b=180
GUESSING this is equiangular, a and b must add up to 120 because they are are both 60.
If a line is 180 degrees and c is 60 (same as a and b) then f will be 180-60 which is 120. 120 is the same as the sum of a and b, so you could write:
a + b = f
The relationship between angles f, b, and a could be as a + b = f.
What is linear pair?Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.
WE can see that the triangle is equiangular and equilateral, Also angles a b and c are the same, so they are interchangeable.
WE know that the base makes the straight line
f + c = 180
So: f + a = 180
Similarly
f + b = 180
Assuming this is equiangular, a and b must be add to 120, they are both 60 degrees
If we consider the line is 180 degrees and c is 60 then f will be 180-60 which is 120.
120 degree is the same as the sum of a and b, so we could write:
a + b = f
Hence, the relationship between angles f, b, and a could be as a + b = f.

3. Explain how to determine when 2 lights blink together.
:
Answers
Answer:
1) both lights will blink at the same time every 20 seconds
2)Both lights will blink at the same time every 36 seconds
3) How to determine when 2 lights will blink together is that you must find the least common factor (LCM) of both numbers and when both hit the same number then that is when both lights blink at the same time.
Step-by-step explanation:
For example for number 1 we have 4 and 5 seconds when the lights blink
4: 4, 8, 12, 16, 20...
5: 5, 10, 15, 20...
we see that the LCM factor is 20 and that is when both lights will hit at the same time.
