Answer:
y
=

Explanation:
First, we need to determine the slope of the line. The formula for determining the slope of a line is:
m
=
y

−
y

where
m
is the slope and the x and y terms are for the points:
(
x
1
,
y
1
)
and
(
x
2
,
y
2
)
For this problem the slope is:
m

Now, selecting one of the points we can use the point slope formula to find the equation.
The point slope formula is:
y

Assume M is the Total Money
M/6 + (1/5)(M - M/6) + $600 = M
M/6 + M/5 - M/30 + $ 600 = M
M/6 + M/5 - M/30 - M = -$600
(1/6 + 1/5 - 1/30 - 1)M = -$600
-2M/3 = -$600
2M/3 = $600
M = ($600)(3/2)
M = $900
so the total money is $900
but the money he gave to his children is only 1/3 of the Total Money(M)
therefore,
=(1/3)($900)
=$300
$300 is the total money he gave to his children
The ratio of the model's height to actual height of tower is 1:725
Step-by-step explanation:
Given
Actual height of Sears Tower =
= 1450 feet
Height of Model =
= 24 inches
We can divide the actual height by the model's height to find the scale
Let z be the ratio of the height of the model to the actual height

The ratio should be in same unit.
We know that
1 ft = 12 inches
Then

Hence,
The ratio of the model's height to actual height of tower is 1:725
