A diagram would be nice. The quick answer is C.
The first answer makes AE 8 which is twice as long as AC. I don't think the intent of the question is to use an external point.
The second one is also incorrect. This time E is in a place such that it makes AC and AE both equal and that too isn't possible.
The third one is the answer because D and E are both 1/2 the distance between the end point of the line containing them.
D is wrong because E is the midpoint of AC but D is not the midpoint of AB.
Ralph is 3 years old
Casey is 18 years old
Step-by-step explanation:
Let the age of Ralph be x
Then Casey is 6 times as old as Ralph will be 6x
In two years
Ralph =x+2
Casey=6x+2 ⇒ 4(x+2)
Equate the two equations for Casey as
6x+2 = 4x+8
6x-4x=8-2
2x=6
x=6/2= 3
Current age;
Ralph= x= 3 years old
Casey=6x = 6*3= 18 years

Answer:
im not 100% bit i think its 95ft
Step-by-step explanation:
This is the concept of trigonometry, we are required to calculate the number of floors the building has given the information above;
# floors=[height of the building]/[height of each floor]
height of each floor=17 ft
let the height of the building be,h.
h is given by;
tan theta=opposite/adjacent
theta=80
opposite=h
adjacent=75 ft
thus
tan 80=h/75
h=75 tan 80
h=425.35 ft
thus the number of floors will be:
425.35/17
=25.020≈25 floors
Answer:
5 hours
Step-by-step explanation:
4/5 is 20 of 25, so there are 5 hours left which is your answer!
