Here are the 6 ways to
write 835 000
1st way = word form way
=> eight hundred thirty five thousands.
2nd way = place value form
=> 8 hundred thousand 3 ten thousand 5 thousand
3rd way = expanded form
=> 800 000 + 30 000 + 5 000
4th way = algebraic form
=> 835 000
5th way = numeric addition form
=> 800 000 + 35 000
6th way = fraction form
=> 835 000 / 1
X/49 = 21/x
x^2 = 21(49) = 1029
x = √1029 = 32.1
x = 32.1
The speed is the ratio between the distance and the time:
Data:
d=6343miles
t=9h
Then, the plane traveled at a speed of 704.77 miles per hour.
X= 100°
180° - 57° = 123
x + 23°= 123°
x = 100°
Answer:
2x+50 and 5x-55 both are congruent or have same measure.
Step-by-step explanation:
Since we want to prove that both lines are parallel, this means no theorems that involve with parallel lines apply here.
First of, we know that AC is a straight line and has a measure as 180° via straight angle.
x+25 and 2x+50 are supplementary which means they both add up to 180°.
Sum of two measures form a straight line which has 180°.
Therefore:-
x+25+2x+50=180
Combine like terms:-
3x+75=180
Subtract 75 both sides:-
3x+75-75=180-75
3x=105
Divide both sides by 3.
x=35°
Thus, x = 35°
Then we substitute x = 35 in every angles/measures.
x+25 = 35°+25° = 60°
2x+50 = 2(35°)+50° = 70°+50° = 120°
5x-55 = 5(35°)-55 = 175°-55° = 120°
Since 2x+50 and 5x-55 have same measure or are congruent, this proves that both lines are parallel.
