Answer:
y = 112
Step-by-step explanation:
If y varies directly as the square of x
mathematically;
y ∝ x²
y = kx² where 'k' is the constant of proportionality
let u know the value of k for this equation by making k the subject of the formular from y = kx²
divide both sides by x²
k = y / x²
given that y = 567 x = 9
k = 567/(9)²
k = 567/81
k = 7
now to get the value of y when x = 4
from the equation conneting x, y,
y = kx²
y = 7 × (4)²
y = 7 × 16
y = 112
The diagonals of a rhombus are perpendicular bisectors of each other, and are also angle bisectors. The 4 congruent right triangles the rhombus is cut into by the two diagonals are 30-60-90 degree triangles, the longer leg is √3/2 of the hypotenuse, √3/2 of 10=5√3. so the longer diagonal is twice of 5√3=10√3
Answer:
ummmm....
Step-by-step explanation:
9/10 , 0.99 , 19/20 , 9%
A) profit is 8$, the price increases 8$ every time or each pie is $4
B)N times 4= P
C) 15 times 4= $60 Profit. Because each pie is 4$
D) if 144$ are made and each pie is $4, you’d divide 144 by 4= 36. 36 Pies were sold.
I hope this is correct and helps :)
