Answer:
similarity
Step-by-step explanation:
look , dude
the two triangles have the following features:
the angle B= angle C = 90 degree
the angle A= the angle F
so the third angle in the first triangle = the third angle in the second triangle
so you have one condition of similarity which is the three angles are equal
to get the answer for lengths :
ab/fe= constant of proportionality
thus ab/fe=2.5/5=.5
so ac/13=.5 thus ac=6.5
and 6/de=.5 so de=12
Answer:
the answer is B. Theme. Hope this helps
Answer:
A
Step-by-step explanation:
The answer is 8i.
i = √(-1)
√(-64) = √((-1) * 64)
= √(-1) * √64
= i * √8²
= i * 8
= 8i
Answer:
The number of children was 170 and adults was 368.
Step-by-step explanation:
To clarify we'll call children by 'c' and adults by 'a'. The amount of people in the pool should be the sum of adults and children, so:
a + c = 538
The receipts for the adimission should total the amount of tickets from children and adults multiplied by the price of each ticket, so:
1.75*c + 2.25*a = 1125.5
We now have two equations and two variables. Using the first equation we can isolate the 'a' variable and use it on the second equation to find an answer. We then have:
a + c = 538
a = 538 - c
Using it on the second equation:
1.75*c + 2.25*(538-c) = 1125.5
1.75*c + 1210.5 - 2.25*c = 1125.5
1.75*c - 2.25*c = 1125.5 - 1210.5
-0.5*c = -85
c = -85/(-0.5) = 170
Using this value on the first equation:
a = 538 - 170 = 368
