Problem 1
1. A green light blinks every 4 seconds and a yellow light blinks every 5 seconds. When will both lights blink at the same time?
:
2. A red light blinks every 12 seconds and a blue light blinks every 9 seconds. When will both lights blink at the same time?
:
3. Explain how to determine when 2 lights blink together.
:
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.
Write an equation in point-slope form for: (-3, 6) and m = 2
Answer:
Step-by-step explanation:
which is greater 225% or 3
Answer:
3 is greater
Step-by-step explanation:
225% as a decimal is 2.25 and you can see that 3 is greater than 2.25
Answer:
3
Step-by-step explanation:
225% = 2.25 = [tex]2\frac{1}{4}[/tex].
So, 3 is greater than 225%.
pls helpppp asapppp with the question above
Answer:
the answer should be B
Step-by-step explanation:
i do apologize if its wrong im like 99.9% sure it correct
Answer:
0
Step-by-step explanation:
4(m+2) = -4(m-2)
by dividing over 4 :
m+2 = -1(m-2)
= m+2 = -m+2
by subtracting 2 :
m = -m
by adding "m" :
2m = 0
So
m = 0
I hope that the explanation is clear for you.
Evaluate help please!
The absolute value of a number is the distance from 0 to that number. The distance is positive, hence, the absolute value is always a positive number.
ExerciseReplace the value of x:
[tex]| x - 8 |[/tex]
[tex]| -4 - 8 |[/tex]
[tex]| -12 | = \large{\boxed{12}}[/tex]
The absolute value of a number is the numerical value of the number, without regard to its sign.
Answer. 12please help me will give you brainliest!!
Answer:
yes, no, no, yes
Step-by-step explanation:
Plug in each point into both equations to see which ones fit.
For the first point, (4,1) it works for both equations.
1=-2( 4 ) + 9, 1= -8 + 9, 1=1
4( 4 )+2( 1 )=18, 16 + 2 = 18, 18 = 18
Do it for the rest of the points and plug them in and you get,
no for (5,-3) because -1 does not equal to -3
no for (6,0) because -3 does not equal to 0
(-5,19) is yes because 19=19 and 18=18

finding missing angles of triangles show your work
Answer:
angle = 50
x = 6
Step-by-step explanation:
solution for angle:
180-(70+60) = 50
solution for x:
8x+2=50 (subtract 2 from both sides)
8x=48 (divide both sides by 8)
x=6

Choose the expression that is equivalent to the expression
n/4 n/4 n/4 n/4. A. N. B. 1/4n. C. 4n. D. 0
Answer:
A. n
Step-by-step explanation:
n/4 + n/4 + n/4 + n/4 = 4n/4 = n
On solving the expression, n/4 + n/4 + n/4 + n/4 , we get n.
What is a expression? What is a mathematical equation? What is equation modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have the following expression -
n/4 + n/4 + n/4 + n/4
We can write -
n/4 + n/4 + n/4 + n/4
n/4(1 + 1 + 1 + 1)
4 x n/4
n
Therefore, on solving the expression, n/4 + n/4 + n/4 + n/4 , we get n.

So what we gotta do is isolate the variable by
writing it out like this
4 1/4 25 those are the numbers where those go are like this
4x - 1/4 < 25 then move on to the next line on here we write out
4x + 1/4 - 1/4 < 25 + 1/4 (The reason why i put + 1/4 is because you have to isolate the variable by doing addition as well And i always find it easier to convert the fractions to decimals then after you make that line you make the next one like this you have to add 1/4 to 4x then take it away (which is 4x) then put that to the side like this 4x ? ? then we need to find those two ?s by adding 25 and 1/4 (or o.25) which is 25.25 then we need to add that to the second answer 4x ? 25.25 when you have this you need to find out which one is bigger so it is 4x<25.25 (or 25 1/4) then we need to divide 4 and 25.25 to get 6.25 so
the answer is x < 6.25 so c is your awnser

What is the measure of angle N?
=========================================================
Work Shown:
Apply the law of sines
sin(N)/MO = sin(O)/MN
sin(N)/18 = sin(17)/6
sin(N) = 18*sin(17)/6
sin(N) = 0.87711511416821 ................. which is approximate
N = arcsin(0.87711511416821)
N = 61.296295678111
N = 61 degrees approximately
----------------------
Notes:
Arcsine is the same as inverse sine. Your calculator is likely to have a button labeled [tex]\sin^{-1}[/tex] to indicate inverse sine.There are two solutions to sin(N) = 0.877; however, the other solution for N is larger than 90. This triangle your teacher is showing appears to be an acute triangle where every angle is less than 90 degrees. Technically two triangles are possible with these current given sides and angle.PLSSSSSSS HELPPPPPPP I WILL GIVE BRAINLIESTTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!PLSSSSSSS HELPPPPPPP I WILL GIVE BRAINLIESTTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!PLSSSSSSS HELPPPPPPP I WILL GIVE BRAINLIESTTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!PLSSSSSSS HELPPPPPPP I WILL GIVE BRAINLIESTTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!PLSSSSSSS HELPPPPPPP I WILL GIVE BRAINLIESTTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!PLSSSSSSS HELPPPPPPP I WILL GIVE BRAINLIESTTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!

Write the equation of a line with a slope of -7/2 passing through the point 2,-4
Answer:
y = -7/2x+3
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -7/2 x+b
Substitute the point into the equation
-4 = -7/2(2) +b
-4 = -7+b
Solving for b
-4+7 = -7+b+7
3 = b
The equation is y = -7/2x+3
