Answer:
126 apples
Step-by-step explanation:
Let the number of apples picked by Mary=m
Cindy picks 6 times as many as Mary= 6Xm=6m
John picks 8 times as many as Mary= 8Xm=8m
Altogether they picked a total of 135 apples.
m+6m+8m=135
15m=135
m=135/15
m=9
We want to determine how many apples John and Cindy Picked.
John Picked 6m apples
Cindy Picked 8m apples
Their combined total= 6m+8m =14m
Since m=9
14m =14 X9 =126 apples
John and Cindy picked a total of 126 apples
Answer:
(3 , 2.5)
Step-by-step explanation:
.5x + y = 4
y = .5x+1
.5x + (.5x + 1) = 4
x + 1 = 4
x = 3
y = .5(3)+1
y = 1.5 + 1
y = 2.5
the answer is 5.196152423
Answer:
k = 2a = 10
Step-by-step explanation:
If
x² / 25 − y² / 56 = 1
we know that
a² = 25 ⇒ a = 5
b² = 256 ⇒ b = √256
The equation of the hyperbola defined by |FP − PG| = k can be written as follows:
|FP − PG| = 2*a
then
2*a = 2*5 = 10
