Answer:
After 120 seconds
Step-by-step explanation:
Here, we want to know the number of seconds after which both spotlights will change colors at the same time again.
Basically, what we want to do here is to
calculate the value with which 30 and 40 have the same multiples or we want to
calculate the lowest common multiple of 30 and 40
The multiples of 30 are 30,60,90,120 etc
The multiples of 40 are 40,80,120 etc
We can see that the lowest common multiple of both is 120
So therefore the spotlights will change colors at the same time after 120 seconds
Answer:
No.
Step-by-step explanation:
A scale copy would see that both the x and y amount would be scaled proportionally. In this case, the x goes across 5 for figure A, and does the same for Figure B. On the other hand, the scaling for y is 2 for figure A, while it is 5 for figure B.
If it is a scale copy then.
If Figure A have the scaling of: 3, 5, 5, x, then Figure B, if given one scale of 5, should have
3:5
5:8.33
5:8.33
x:(x * ~1.67)
Therefore, the scaling is off.
Answer:
1) x = 4 2) x = 4 3) x = -4 4) x = 3 5) x = 5 6) x = 9 7) x = -8
8) x = 11 9) x = -5 10) x = -4
Step-by-step explanation:
Alternate Exterior and Alternate Interior angles are equal to each other. Just set the numbers or equations the give you equal to each other.
Question 1: Question 2: Question 3: Question 4:
33x+3=135 120=31x-4 120=x+124 40x+5=42x-1
33x=132 124=31x -4=x 6=2x
x=4 x=4 x= -4 x=3
Question 5: Question 6: Question 7: Question 8:
20x+4=19x+9 11x= -9+12x 80=x+88 10x+20=12x-2
-5= -x -x = -9 -8 = x 22=2x
x=5 x= 9 x= -8 x=11
Question 9: Question 10:
70=x+75 130=x+134
-5 = x -4 = x
x = -5 x= -4
