What is the total price of a $3.25 sandwich and a $1.10 drink including 7% sale tax?

1 answer:

3 0

Okay so start by finding the cost of the sandwich and the drink together. Once you have that number you need to find what 7% (or 0.07) or that number is. HINT it should be less than $0.50. Add this 7% to your sandwich-drink total and ta-da!!!

*WILL GIVE BRAINLIEST* the following function represents the production cost f(x), in dollars, for x number of units produced by

Trava [24]

Answer:

Step-by-step explanation:

By analyzing the functions f(x) and g(x), we can see that they are both quadratic relations.

To find the minimum value, we want to find the y-coordinate of the vertex.

In f(x), by using the formula (-b/2a), we get the x-coordinate of the vertex, 70. When we substitute 70 into the function, we get 55 as our minimum.

In h(x), we can see that the lowest y-coordinate in the given points is 899.52. So (1, 899.50) is our vertex.

This means that in f(x), the minimum production cost is $70. In contrast, in h(x), the minimum production cost is $899.50. Therefore f(x) has a lower minimum, with its minimum value at (70, 55), our vertex.

The equation for decibels and sound intensity is D=10log(sub 10) I/I(sub0) where D is decibels.

velikii [3]

$D=10\log\dfrac{I}{I_0}\\\\
D=10\log\dfrac{10^{11}}{10^{-12}}\\
D=10\log10^{23}\\
D=10\cdot23=\\
D=230$
