The correct answer is C, 6/7
Answer:
The geometric mean of the measures of the line segments AD and DC is 60/13
Step-by-step explanation:
Geometric mean: BD² = AD×DC
BD = √(AD×DC)
hypotenuse/leg = leg/part
ΔADB: AC/12 = 12/AD
AC×AD = 12×12 = 144
AD = 144/AC
ΔBDC: AC/5 = 5/DC
AC×DC = 5×5 = 25
DC = 25/AC
BD = √[(144/AC)(25/AC)]
BD = (12×5)/AC
BD= 60/AC
Apply Pythagoras theorem in ΔABC
AC² = 12² + 5²
AC² = 144+ 25 = 169
AC = √169 = 13
BD = 60/13
The geometric mean of the measures of the line segments AD and DC is BD = 60/13
Answer:
y = 4x - 1
Step-by-step explanation:
y = mx + b
Here m is slope and b is y-intercept
m = 4; b = -1
y = 4x - 1
Answer:
79.617...
Step-by-step explanation:
When you are trying to find the circumfrence you do c=πd
So to find the diameter you reverse it
Since you already know the 250 feet you divide it by π
You then get 79.6
Simply divide 23 and 2/5 bags of apples between 9 friends:
23 and 2/5 bags ÷ 9 friends= 117/5 bags ÷ 9 friends
= 13/5 bags
= 2 and 3/5 bags
Therefore, each friend receives 2 and 3/5 bags of apples.
Hope this helps!
