Answer:
y = 
Step-by-step explanation:
Straight line in the graph attached shows the linear relation between number of gallons of white paint and number of gallons of red paint added to prepare pink.
Let the number of gallons of white paint required = x
and number of gallons of red paint required = y
y ∝ x
y = kx [k = proportionality constant]
Since a point (4, 1) lies on this line,
1 = 4k
k = 
Therefore, equation that describes the relationship will be,
y =
Answer:
108 degrees difference.
Step-by-step explanation:
63+45=108
Answer:
60 mph
Step-by-step explanation:
mph=miles/hours
240/4=60
60 miles per hour
There are 1.6 5/8's in 1
1.6 is the same as 8/5.
The are 8/5 5/8's in 1
Another way to solve this problem is:
Since we can set it up as:
1/
=8/5
We can also set the problem up as:
5/8*x=1
Then, we can apply the reciprocal rule:
a/b*b/a=1
5/8*8/5=1
The final answer is there are 8/5 5/8's in 1
Answer:
Bc = √63 ft
Step-by-step explanation:
Here, we want to get the length of BC
As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side
So we want to get the third leg which is BC
we can use the Pythagoras’ theorem here
And that states that the square of the hypotenuse equals the sum of the squares of the two other sides
let the missing length be x
12^2 = x^2 + 9^2
144 = x^2 + 81
x^2 = 144-81
x^2 = 63
x = √63 ft
