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:
2520
Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference.
To find the number of terms given = - 10 , d = - 2 and a₁ = 100, then
100 - 2(n - 1) = - 10 ( subtract 100 from both sides )
- 2(n - 1) = - 110 ( divide both sides by - 2 )
n - 1 = 55 ( add 1 to both sides )
n = 56 ← number of terms
Given n, a₁ and a₅₆ , then the sun of the terms is
= (a₁ + a₅₆ )
= (100 - 10) = 28 × 90 = 2520
The slope is -3/2
Hope this help!
Answer:
x>3/4
Step-by-step explanation:
Reinterpreting the question, it's asking us to find which coin has a closer probability to 50% of getting either heads or tails.
Coin A
205 / 500 = .41 = 41%
Coin B
120 / 250 = .48 = 48%
Since 48% is closer to 50% than 41% is, coin B is the fairest.
