Answer:
your answer should be 37:7
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 777 and 147 is 21
Divide both terms by the GCF, 21:
777 ÷ 21 = 37
147 ÷ 21 = 7
The ratio 777 : 147 can be reduced to lowest terms by dividing both terms by the GCF = 21 :
777 : 147 = 37 : 7
Therefore:
777 : 147 = 37 : 7
Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2

Answer:
it would be C do to the fact that 0.5 x 8=4
Answer:
1 /1 ; 360°
Step-by-step explanation:
Start time = 2:30 pm
Stop time = 3:30 pm
Minute hand makes a complete revolution per hour ;
This means that the minutes hand revolves round the whole circle in one hour, hence fraction of the circle covered by the minute hand between 2:30 pm - 3:30 pm is 1/1 = 1
The angle turned by the minutes hand :
1 complete revolution = 360°
A circle covers 360°
1 /1 fraction of a circle = 1/1 * 360° = 360°
Hence, angle turned by the minute hand = 360°
