8(51)
=8(50+1)
=(8*50)+(8*1)
=(8*5*10)+(8*1)
=400+8
=408
Answer:
Please check the explanation.
Step-by-step explanation:
We know the equation
y = kx
k = y/x
where k is the proportionality constant
so,
First ratio can be calculated as
Miles = 45
Hours = 3/4
The ratio = 45 / (3/4)
= (45 × 4) / 3
= 180/3
= 60
Thus, the proportionality constant = 60
Thus, the remaining ratios can be calculated as:
The Pair (135, Hours)
135/Hours = 60
Hours = 135 / 60
= 27/12
= 9/4
= 2.25
Thus, the pair is (135, 2.25)
The Pair (Miles, 3)
Miles/3 = 60
Miles = 60×3
= 180
The Pair (90, Hours)
90/Hours = 60
Hours = 90 / 60
= 3/2
= 1.5
Thus, the complete table:
Miles 45 135 180 90
Hours 3/4 9/4 3 3/2
Verification:
Miles / Hour = 45/(3/4) = 60
Miles / Hour = 135 / 2.25 = 60
Miles / Hour = 180 / 3 = 60
Miles / Hour = 90 / 1.5 = 60
It’s 40 because it’s closer to 40 than 30
I think it’s 2
Hope that helped sorry if it’s wrong
Answer:
C. (9,1)
Step-by-step explanation:
Let the coordinated of Jaydas House be:
A(x_1, y_1) = (1,5)
The coordinates of Christian's House be:
B( x_2, y_2)
Let the restaurant be
M(x_M, y_M) = (7,2)
The ratio is 3:1
So
m=3 and n=1
So by the formula of finding the point that divides lines into given ratios
Therefore the coordinates of Christian's house are (9,1)
Option C is correct ..
