Very buys a basket of mangoes that is priced $14 before tax. The sales tax is 6%. What is the total price Avery pays for t

igor_vitrenko [27]

Answer:

Avery needs to pay $14.84

Step-by-step explanation:

When there's a tax we need to sum the original value of the product with the tax's value. To find the amount of money Avery needs to pay in taxes we can apply a rule of three as shown below:

$\frac{14}{x} = \frac{100}{6} \frac{\%}{\%}$

Where "x" is the tax value, and $14 represents 100%, since it's the value used to calculate the tax. We have:

$x = \frac{14*6}{100}\\x = \frac{84}{100}\\x = 0.84$

The value to be paid is the product value plus the tax, therefore:

$\text{paid} = 14 + 0.84 = 14.84$

Avery needs to pay $14.84

A street sign is 104 inches tall. How tall is it in feet and inches.

ikadub [295]

Answer:

8 ft 8 in

Step-by-step explanation:

104/12 = 8.666...

This shows that there are 8 total feet because there are 12 inches in a foot

Then, multiply 8*12 to get 96 in order to get the remainder of the inches left that do not make up one whole foot.

Then subtract 96 from 104 (104-96) to get the remainder which is 8 inches.

PLEASE HELP ME I HAVING TROUBLE

Answer: f(-6) = $-\frac{12}{11}$ , f(-4) = $\frac{8}{9}$ , f(4) = $-\frac{8}{9}$ , f(6) = $\frac{12}{11}$

<u>Step-by-step explanation:</u>

(-6, f(-6)) is an x,y coordinate. They are asking what the y-value is when you plug in -6 for x.

f(x) = $\frac{2x}{x^{2}-25}$

f(-6) = $\frac{2(-6)}{(-6)^{2}-25}$

= $\frac{-12}{36-25}$

= $-\frac{12}{11}$

f(-4) = $\frac{2(-4)}{(-4)^{2}-25}$

= $\frac{-8}{16-25}$

= $\frac{-8}{-9}$

= $\frac{8}{9}$

f(4) = $\frac{2(4)}{(4)^{2}-25}$

= $\frac{8}{16-25}$

= $\frac{8}{-9}$

= $-\frac{8}{9}$

f(6) = $\frac{2(6)}{(6)^{2}-25}$

= $\frac{12}{36-25}$

= $\frac{12}{11}$
