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
'of' means mltilply
jane=2/9 of ben
ben=3/4
jane=2/9 of 3/4
jane=2/9 times 3/4=(2*3)/(9*4)=6/36=1/6 miles
Answer:
16%
Step-by-step explanation:
so you already know 35% like both and 17% like apples and 32% like neither
add those and get 84. we know that the percent is over 100 . So far you have 84% meaning there is only 16% left . Therefore 16% like bananas
(x + 2)(x - 4)
= x^2 + 2x - 4x - 8
= x^2 - 2x - 8
FIND TAX
=$3950 * 6%
=3950 * 0.06
=$237 tax
FIND TOTAL
add tax above to bike price
=$3950 + $237
=$4187 total
ANSWER: The cost of the motorbike with tax is $4187.
Hope this helps! :)
