A retailer purchased an electric bicycle for Rs. 35000 and sold at a profit of 16% to a customer. How much did the customer pay

motikmotik

Answer:

Rs. 45,150

Step-by-step explanation:

Given data

Cost =Rs. 35000

Profit=16%

VAT=13%

Let us find the profit to be added

=16/100*35000

=0.16*35000

=Rs. 5,600

Let us find the VAT to be added

=13/100*35000

=0.13*35000

=Rs. 4,550

Hence the cost of the bike is

=4,550+ 5,600+ 35000

=Rs. 45,150

fredd [130]

Answer: D . $N(t) = 3 + (0.25t)^3 - 8(1.06)^t$

Step-by-step explanation:

Given : Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is represented by the function,

$A(t) = 5 + (0.25t)^3$

The number of bacteria of species B, B(t), after t hours is represented by the function, $B(t) = 2 + 8(1.06)^t$

Then, the difference in the number of bacteria, N(t), of both the species after t hours will be :-

$N(t)=A(t)-B(t)\\\\=5 + (0.25t)^3-(2 + 8(1.06)^t)\\\\=5 + (0.25t)^3-2-8(1.06)^t\\\\=5-2 +(0.25t)^3-8(1.06)^t\\\\=3+(0.25t)^3-8(1.06)^t$

Hence, the correct answer should be : D . $N(t) = 3 + (0.25t)^3 - 8(1.06)^t$

Which expression can be used to find the length of AT?

irina [24]

Answer:

$\large\boxed{\large\boxed{\overline{AT}=12.5(cos66\º)}}$

Explanation:

In a right triangle the angle between the hypotenuse and the adjacent leg to the angle are related by the trigonometric ratio cosine.

Cosine is the ratio of the adjacent leg to the hypotenuse:

In the right triangle ART, AT is the hypotenuse, AR is the ajacent leg to the angle 66º, and RT is the opposite leg to the angle 66º.

Then, the length of AT and 12.5 is related by the cosine ratio:

$cos(66\º)=\dfrac{\overline{AT}}{12.5}$

Multiplying both sides of the equation by 12.5in:

$\overline{AT}=12.5(cos66\º)$ ← answer
