An equation has infinitely many solutions if it can be manipulated all the way to an identity (i.e. an equality where the right and left hand side are the same). We have:
A) 
which is impossible
B) 
which is an equality
C) 
which has a unique solution
D) 
which has a unique solution
Answer:
a person travel 50 ft from the bottom to the top of the escalator
Step-by-step explanation:
An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle
The escalator forms a right angle triangle
opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse
let x be the hypotenuse
a person travel 50 ft from the bottom to the top of the escalator
Answer:
160 trust me
Step-by-step explanation:
we multiply the length by the width which is the formula of finding rectangular areas'
Honestly, this one works out to be a quadratic (which I don't really feel like going into detail) . . . so instead, since this one is fairly simple to think about, I'll simply try "trial and error" . . .
Possible combinations:
1 × 36 = 36
2 × 18 = 36
3 × 12 = 36
4 × 9 = 36
6 × 6 = 36
Obviously, multiply 4 × 2 = 8 . . . and 9 is one more than 8, which is 2 times the first number, 4 . . . so that's your answer . . .
the numbers are 4 and 9
Answer:
false in all cases
Step-by-step explanation:
1) they are not supplementary ,cuz sum is not 180
2) false,cuz sum is not 90°
3) measure of AOB is not 60° and OC not bisecting them
4) measure of AOB is not 60° and OB not bisectijg AOC
